Tags Share this article 8/9/23 Published A firewall that runs 24/7 requires a good amount of computing resources. Especially if you are running a complex firewall system, your performance overhead can actually slow down the overall throughput of your systems and even affect the actual functionalities of your firewall. Here is a brief overview of common firewall performance issues and the best practices to help you tune your firewall performance . 7 Common performance issues with firewalls Since firewall implementations often include some networking hardware usage, they can slow down network performance and traffic bottlenecks within your network. 1. High CPU usage The more network traffic you deal with, the more CPU time your server will need. When a firewall is running, it adds to CPU utilization since the processes need more power to execute the network packet analysis and subsequent firewall This may lead to firewall failures in extreme cases where the firewall process is completely shut down or the system experiences a noticeable lag affecting overall functionality. A simple way to resolve this issue would be to increase the hardware capabilities. But as that might not be a viable solution in all cases, you must consider minimizing the network traffic with router-level filtering or decreasing the server load with optimized 2. Route flapping Router misconfiguration or hardware failure can cause frequent advertising of alternate routes. This will increase the load on your resources and thus lead to performance issues. 3. Network errors and discards A high number of error packets or discarded packets can burden your resources as these packets are still processed by the firewall even when they ultimately turn out to be dud in terms of traffic. Such errors usually happen when routers try to reclaim some buffer space. 4. Congested network access link Network access link congestion can be caused due to a bottleneck happening between a high bandwidth IP Network and LAN. When there is high traffic, the router queue gets filled and causes jitters and time delays. When there are more occurrences of jitter, more packets are dropped on the receiving end, causing a degradation of the quality of audio or video being transmitted. This issue is often observed in VoIP systems . 5. Network link failure When packet loss continues for over a few seconds, it can be deemed a network link failure. While re-establishing the link could take just a few seconds, the routers may already be looking for alternate routes. Frequent network link failures can be a symptom of power supply or hardware issues. 6. Misconfigurations Software or hardware misconfigurations can easily lead to overloading of LAN, and such a burden can easily affect the system’s performance. Situations like these can be caused by misconfigured multicast traffic and can affect the overall data transfer rate of all users. 7. Loss of packets Loss of packets can cause timeout errors, retransmissions, and network slowness. Loss of packets can happen due to delayed operations, server slowdown, misconfiguration, and several other reasons. How to fine-Tune your firewall performance Firewall performance issues can be alleviated with hardware upgrades. But as you scale up, upgrading hardware at an increasing scale would mean high expenses and an overall inefficient system. A much better cost-effective way to resolve firewall performance issues would be to figure out the root cause and make the necessary updates and fixes to resolve the issues. Before troubleshooting, you should know the different types of firewall optimization techniques: Hardware updates Firewall optimization can be easily achieved through real-time hardware updates and upgrades. This is a straightforward method where you add more capacity to your computing resources to handle the processing load of running a firewall. General best practices This involves the commonly used universal best practices that ensure optimized firewall configurations and working. Security policies, data standard compliances , and keeping your systems up to date and patched will all come under this category of optimizations. Any optimization effort generally applied to all firewalls can be classified under this type. Vendor specific Optimization techniques designed specifically to fit the requirements of a particular vendor are called vendor-specific optimizations. This calls for a good understanding of your protected systems, how traffic flows, and how to minimize the network load. Model specific Similar to vendor-specific optimizations, model-specific optimization techniques consider the particular network model you use. For instance, the Cisco network models usually have debugging features that can slow down performance. Similarly, the PIX 6.3 model uses TCP intercept that can slow down performance. Based on your usage and requirements, you can turn the specific features on or off to boost your firewall performance. Best practices to resolve the usual firewall performance bottlenecks Here are some proven best practices to improve your firewall’s performance. Additionally, you might also want to read Max Power by Timothy Hall for a wholesome understanding. Standardize your network traffic Any good practice starts with rectifying your internal errors and vulnerabilities. Ensure all your outgoing traffic aligns with your cybersecurity standards and regulations. Weed out any application or server sending out requests that don’t comply with the security regulations and make the necessary updates to streamline your network. Router level filtering To reduce the load on your firewall applications and hardware, you can use router-level network traffic filtering. This can be achieved by making a Standard Access List filter from the previously dropped requests and then routing them using this list for any other subsequent request attempts. This process can be time-consuming but is simple and effective in avoiding bottlenecks. Avoid using complicated firewall rules Complex firewall rules can be resource heavy and place a lot of burden on your firewall performance. Simplifying this ruleset can boost your performance to a great extent. You should also regularly audit these rules and remove unused rules. To help you clean up firewall rules, you can start with Algosec’s firewall rule cleanup and performance optimization tool . Test your firewall Regular testing and auditing of your firewall can help you identify any probable causes for performance slowdown. You can collect information on your network traffic and use it to optimize how your firewall operates. You can use Algosec’s firewall auditor services to take care of all your auditing requirements and ensure compliance at all levels. Make use of common network troubleshooting tools To analyze the network traffic and troubleshoot your performance issues, you can use common network tools like netstat and iproute2. These tools provide you with network stats and in-depth information about your traffic that can be well utilized to improve your firewall configurations. You can also use check point servers and tools like SecureXL, and CoreXL. Follow a well-defined security policy As with any security implementation, you should always have a well-defined security policy before configuring your firewalls. This gives you a good idea of how your firewall configurations are made and lets you simplify them easily. Change management is also essential to your firewall policy management process . You should also document all the changes, reviews, and updates you make to your security policies to trace any problematic configurations and keep your systems updated against evolving cyber threats. A good way to mitigate security policy risks is to utilize AlgoSec. Network segmentation Segmentation can help boost performance as it helps isolate network issues and optimize bandwidth allocation. It can also help to reduce the traffic and thus further improve the performance. Here is a guide on network segmentation you can check out. Automation Make use of automation to update your firewall settings. Automating the firewall setup process can greatly reduce setup errors and help you make the process more efficient and less time-consuming. You can also extend the automation to configure routers and switches. Algobot is an intelligent chatbot that can effortlessly handle network security policy management tasks for you. Handle broadcast traffic efficiently You can create optimized rules to handle broadcast traffic without logging to improve performance. Make use of optimized algorithms Some firewalls, such as the Cisco Pix, ASA 7.0 , Juniper network models, and FWSM 4.0 are designed to match packets without dependency on rule order. You can use these firewalls; if not, you will have to consider the rule order to boost the performance. To improve performance, you should place the most commonly used policy rules on the top of the rule base. The SANS Institute recommends the following order of rules: Anti-spoofing filters User permit rules Management permit rules Noise drops Deny and alert Deny and log DNS objects Try to avoid using DNS objects that need DNS lookup services. This slows down the firewall. Router interface design Matching the router interface with your firewall interface is a good way to ensure good performance. If your router interface is half duplex and the firewall is full duplex, the mismatch can cause some performance issues. Similarly, you should try to match the switch interface with your firewall interface, making them report on the same speed and mode. For gigabit switches, you should set up your firewall to automatically adjust speed and duplex mode. You can replace the cables and patch panel ports if you cannot match the interfaces. VPN If you are using VPN and firewalls, you can separate them to remove some VPN traffic and processing load from the firewall and thus increase the performance. UTM features You can remove the additional UTM features like Antivirus, and URL scanning features from the firewall to make it more efficient. This does not mean you completely eliminate any additional security features. Instead, just offload them from the firewall to make the firewall work faster and take up fewer computing resources. Keep your systems patched and updated Always keep your systems, firmware, software, and third-party applications updated and patched to deal with all known vulnerabilities.

Cloud Security Emerging Tech Trends – 2023 Perspective Ava Chawla 2 min read Ava Chawla 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 11/24/22 Published 1. Application-centric security Many of today’s security discussions focus on compromised credentials, misconfigurations, and malicious or unintentional misuse of resources. Disruptive technologies from Cloud to smart devices and connected networks mean the attack surface is growing. Security conversations are increasingly expanding to include business-critical applications and their dependencies. Organizations are beginning to recognize that a failure to take an application-centric approach to security increases the potential for unidentified, unmitigated security gaps and vulnerabilities. 2. Portable, agile, API & automation driven enterprise architectures Successful business innovation requires the ability to efficiently deploy new applications and make changes without impacting downstream elements. This means fast deployments, optimized use of IT resources, and application segmentation with modular components that can seamlessly communicate. Container security is here to stay Containerization is a popular solution that reduces costs because containers are lightweight and contain no OS. Let's compare this to VMs, like containers, VMs allow the creation of isolated workspaces on a single machine. The OS is part of the VM and will communicate with the host through a hypervisor. With containers, the orchestration tool manages all the communication between the host OS and each container. Aside from the portability benefit of containers, they are also easily managed via APIs, which is ideal for modular, automation-driven enterprise architectures. The growth of containerized applications and automation will continue. Lift and Shift left approach will thrive Many organizations have started digital transformation journeys that include lift and shift migrations to the Cloud. A lift and shift migration enables organizations to move quickly, however, the full benefits of cloud are not realized. Optimized cloud architectures have cloud automation mechanisms deployed such as serverless (i.e – AWS Lamda), auto-scaling, and infrastructure as code (IaC) (i.e – AWS Cloud Formation) services. Enterprises with lift and shift deployments will increasingly prioritize a re-platform and/or modernization of their cloud architectures with a focus on automation. Terraform for IaC is the next step forward With hybrid cloud estates becoming increasingly common, Terraform-based IaC templates will increasingly become the framework of choice for managing and provisioning IT resources through machine-readable definition files. This is because Terraform, is cloud-agnostic, supporting all three major cloud service providers and can be used for on-premises infrastructure enabling a homogenous IaC solution across multi-cloud and on-premises. 3. Smart Connectivity & Predictive Technologies The growth of connected devices and AI/ML has led to a trend toward predictive technologies. Predictive technologies go beyond isolated data analysis to enable intelligent decisions. At the heart of this are smart, connected devices working across networks whose combined data 1. enables intelligent data analytics and 2. provides the means to build the robust labeled data sets required for accurate ML (Machine Learning) algorithms. 4. Accelerated adoption of agentless, multi-cloud security solutions Over 98% of organizations have elements of cloud across their networks. These organizations need robust cloud security but have yet to understand what that means. Most organizations are early in implementing cloud security guardrails and are challenged by the following: Misunderstanding the CSP (Cloud Service Provider) shared responsibility model Lack of visibility across multi-cloud networks Missed cloud misconfigurations Takeaways Cloud security posture management platforms are the current go-to solution for attaining broad compliance and configuration visibility. Cloud-Native Application Protection Platforms (CNAPP) are in their infancy. CNAPP applies an integrated approach with workload protection and other elements. CNAPP will emerge as the next iteration of must have cloud security platforms. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/2/23 Published Cloud threats are at an all-time high. But not only that, hackers are becoming more sophisticated with cutting-edge tools and new ways to attack your systems. Cloud service providers can only do so much. So, most of the responsibility for securing your data and applications will still fall on you. This makes it critical to equip your organization’s cloud architects and security teams with the necessary skills that help them stay ahead of the evolving threat landscape. Although the core qualities of a cloud architect remain the same, upskilling requires them to learn emerging skills in strategy, leadership, operational, and technical areas. Doing this makes your cloud architects and security teams well-rounded to solve complex cloud issues and ensure the successful design of cloud security architecture. Here, we’ll outline the top skills for cloud architects. This can be a guide for upskilling your current security team and hiring new cloud security architects. But besides the emerging skills, what are the core responsibilities of a cloud security architect? Responsibilities of Cloud Security Architects A cloud security architect builds, designs, and deploys security systems and controls for cloud-based computing services and data storage systems. Their responsibilities will likely depend on your organization’s cloud security strategy. Here are some of them: 1. Plan and Manage the Organization’s Cloud Security Architecture and Strategy: Security architects must work with other security team members and employees to ensure the security architecture aligns with your organization’s strategic goals. 2. Select Appropriate Security Tools and Controls: Cloud security architects must understand the capabilities and limitations of cloud security tools and controls and contribute when selecting the appropriate ones. This includes existing enterprise tools with extensibility to cloud environments, cloud-native security controls, and third-party services. They are responsible for designing new security protocols whenever needed and testing them to ensure they work as expected. 3. Determine Areas of Deployments for Security Controls: After selecting the right tools, controls, and measures, architects must also determine where they should be deployed within the cloud security architecture. 4. Participating in Forensic Investigations: Security architects may also participate in digital forensics and incident response during and after events. These investigations can help determine how future incidents can be prevented. 5. Define Design Principles that Govern Cloud Security Decisions: Cloud security architects will outline design principles that will be used to make choices on the security tools and controls to be deployed, where, and from which sources or vendors. 6. Educating employees on data security best practices: Untrained employees can undo the efforts of cloud security architects. So, security architects must educate technical and non-technical employees on the importance of data security. This includes best practices for creating strong passwords, identifying social engineering attacks, and protecting sensitive information. Best Practices for Prioritizing Cloud Security Architecture Skills Like many other organizations, there’s a good chance your company has moved (or is in the process of moving) all or part of its resources to the cloud. This could either be a cloud-first or cloud-only strategy. As such, they must implement strong security measures that protect the enterprise from emerging threats and intrusions. Cloud security architecture is only one of many aspects of cloud security disciplines. And professionals specializing in this field must advance their skillset to make proper selections for security technologies, procedures, and the entire architecture. However, your cloud security architects cannot learn everything. So, you must prioritize and determine the skills that will help them become better architects and deliver effective security architectures for your organization. To do this, you may want to consider the demand and usage of the skill in your organization. Will upskilling them with these skills solve any key challenge or pain point in your organization? You can achieve this by identifying the native security tools key to business requirements, compliance adherence, and how cloud risks can be managed effectively. Additionally, you should consider the relevance of the skill to the current cloud security ecosystem. Can they apply this skill immediately? Does it make them better cloud security architects? Lastly, different cloud deployment (e.g., a public, private, edge, and distributed cloud) or cloud service models (e.g., Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS)) bring unique challenges that demand different skillsets. So, you must identify the necessary skills peculiar to each proposed project. Once you have all these figured out, here are some must-have skillsets for cloud security architects. Critical Skills for Cloud Security Architect Cloud security architects need several common skills, like knowledge of programming languages (.NET, PHP, Python, Java, Ruby, etc.), network integration with cloud services, and operating systems (Windows, macOS, and Linux). However, due to the evolving nature of cloud threats, more skills are required. Training your security teams and architects can have more advantages than onboarding new recruits. This is because existing teams are already familiar with your organization’s processes, culture, and values. However, whether you’re hiring new cloud security architects or upskilling your current workforce, here are the most valuable skills to look out for or learn. 1. Experience in cloud deployment models (IaaS, PaaS, and SaaS) It’s important to have cloud architects and security teams that integrate various security components in different cloud deployments for optimal results. They must understand the appropriate security capabilities and patterns for each deployment. This includes adapting to unique security requirements during deployment, combining cloud-native and third-party tools, and understanding the shared responsibility model between the CSP and your organization. 2. Knowledge of cloud security frameworks and standards Cloud security frameworks, standards, and methodologies provide a structured approach to security activities. Interpreting and applying these frameworks and standards is a critical skill for security architects. Some cloud security frameworks and standards include ISO 27001, ISAE 3402, CSA STAR, and CIS benchmarks. Familiarity with regional or industry-specific requirements like HIPAA, CCPA, and PCI DSS can ensure compliance with regulatory requirements. Best practices like the AWS Well-Architected Framework, Microsoft Cloud Security Benchmark, and Microsoft Cybersecurity Reference Architectures are also necessary skills. 3. Understanding of Native Cloud Security Tools and Where to Apply Them Although most CSPs have native tools that streamline your cloud security policies, understanding which tools your organization needs and where is a must-have skill. There are a few reasons why; it’s cost-effective, integrates seamlessly with the respective cloud platform, enhances management and configuration, and aligns with the CSP’s security updates. Still, not all native tools are necessary for your cloud architecture. As native security tools evolve, cloud architects must constantly be ahead by understanding their capabilities. 4. Knowledge of Cloud Identity and Access Management (IAM) Patterns IAM is essential for managing user access and permissions within the cloud environment. Familiarity with IAM patterns ensures proper security controls are in place. Note that popular cloud service providers, like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, may have different processes for implementing IAM. However, the key principles of IAM policies remain. So, your cloud architects must understand how to define appropriate IAM measures for access controls, user identities, authentication techniques like multi-factor authentication (MFA) or single sign-on (SSO), and limiting data exfiltration risks in SaaS apps. 5. Proficiency with Cloud-Native Application Protection Platforms CNAPP is a cloud-native security model that combines the capabilities of Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), and Cloud Service Network Security (CSNS) into a single platform. Cloud solutions like this simplify monitoring, detecting, and mitigating cloud security threats and vulnerabilities. As the nature of threats advances, using CNAPPs like Prevasio can provide comprehensive visibility and security of your cloud assets like Virtual Machines, containers, object storage, etc. CNAPPs enable cloud security architects to enhance risk prioritization by providing valuable insights into Kubernetes stack security configuration through improved assessments. 6. Aligning Your Cloud Security Architecture with Business Requirements It’s necessary to align your cloud security architecture with your business’s strategic goals. Every organization has unique requirements, and your risk tolerance levels will differ. When security architects are equipped to understand how to bridge security architecture and business requirements, they can ensure all security measures and control are calibrated to mitigate risks. This allows you to prioritize security controls, ensures optimal resource allocation, and improves compliance with industry-specific regulatory requirements. 7. Experience with Legacy Information Systems Although cloud adoption is increasing, many organizations have still not moved all their assets to the cloud. At some point, some of your on-premises legacy systems may need to be hosted in a cloud environment. However, legacy information systems’ architecture, technologies, and security mechanisms differ from modern cloud environments. This makes it important to have cloud security architects with experience working with legacy information systems. Their knowledge will help your organization solve any integration challenges when moving to the cloud. It will also help you avoid security vulnerabilities associated with legacy systems and ensure continuity and interoperability (such as data synchronization and maintaining data integrity) between these systems and cloud technologies. 8. Proficiency with Databases, Networks, and Database Management Systems (DBMS) Cloud security architects must also understand how databases and database management systems (DBMS) work. This knowledge allows them to design and implement the right measures that protect data stored within the cloud infrastructure. Proficiency with databases can also help them implement appropriate access controls and authentication measures for securing databases in the cloud. For example, they can enforce role-based access controls (RBAC) within the database environment. 9. Solid Understanding of Cloud DevOps DevOps is increasingly becoming more adopted than traditional software development processes. So, it’s necessary to help your cloud security architects embrace and support DevOps practices. This involves developing skills related to application and infrastructure delivery. They should familiarize themselves with tools that enable integration and automation throughout the software delivery lifecycle. Additionally, architects should understand agile development processes and actively work to ensure that security is seamlessly incorporated into the delivery process. Other crucial skills to consider include cloud risk management for enterprises, understanding business architecture, and approaches to container service security. Conclusion By upskilling your cloud security architects, you’re investing in their personal development and equipping them with skills to navigate the rapidly evolving cloud threat landscape. It allows them to stay ahead of emerging threats, align cloud security practices with your business requirements, and optimize cloud-native security tools. Cutting-edge solutions like Cloud-Native Application Protection Platforms (CNAPPs) are specifically designed to help your organization address the unique challenges of cloud deployments.

Tags Share this article 12/6/22 Published As 2022 comes to a close, Professor Avishai Wool, AlgoSec Co-Founder and CTO, provides his top 5 issues organizations will need to be aware in 2023 that will also dominate the cyber community conversation. 1) Application centric approach to network security will supersede basic NSPM I think the market has matured to the point where the NSPM approach has reached a tipping point and I see the shift to an application perspective becoming the de facto approach in network security policy management as there are better and more robust technologies in the market that can help organizations get there faster. I see this shift becoming even more viable in 2023 based on recent market trends in which organizations are opting for downsizing and trying to do more with the smaller staff at the expense of losing tribal knowledge. As a result, I see organizations shifting more towards adopting a holistic approach to network security that are more application centric in which they can retain critical knowledge, such as application traffic intent and application policy rules, so that the new generations can step in and pick up where the previous predecessors left off. 2) Containerization will enhance layered security I expect container security to be increasingly popular in the future, as companies understand that their existing network security mechanisms are not enough for the communication networks of today. Containers are seen as a cost-effective light-weight solution for deployment – and deploying them introduces another inner layer where security policies can be applied: behind the perimeter filters, the internal zoning, and the micro-segmentation, organizations can now also consider nano-segmentation at the container level. Vulnerability testing is another dimension of the container platform especially within cloud applications and SaaS products. The common Kubernetes platform offers both opportunities and challenges for vulnerability scanners. Beyond 2023 , businesses will need to enhance both their visibility and management capabilities of security within their containerized applications 3) Security driven IaaS ecosystems to improve network security I expect the popularity of Infrastructure as a service (IaaS) to continue to soar, making it difficult for security teams to keep up with the associated risks and vulnerabilities. Pre-set security settings may not meet the needs of the organization and customizing these settings can prove to be difficult. The customizability of IaaS offers great potential for productivity, but it also makes it complicated to secure. The bottom line is that companies can no longer depend on their network perimeter to guard sensitive data. In response, I anticipate organizations that begin utilizing an “Always-on Security” approach such as Infrastructure as Code (IaC) which would permit them to construct personalized policies to control the development environments during each phase of the software development life cycle (SDLC) and recognize potential risks, security flaws, and compliance issues on a what-if basis, before deploying flawed settings into production. 4) Cloud-native security tools will reign supreme I expect that cloud-based security systems will become more commonplace: these security solutions offer a wide range of abilities, such as secure access, identity and access management, data loss prevention, application security, automation of security, detection and prevention of intrusions, security information and event management, and encryption. With companies transitioning more workloads to the cloud, they will want to make use of many of these features. These tools make it possible for remote teams to manage a greater public cloud presence: comfortably configuring services and automating processes, to identify and preemptively tackle any kind of threats. To bridge the gap in cloud data security, I anticipate the emergence of data safeguarding systems that are designed specifically for cloud usage and are able to link up with public cloud systems in an advanced, agentless manner. This has been classified in the market as Cloud Native Application Protection Platform (CNAPP) . These platforms must be able to detect where the data is stored and what sorts of data are stored in the cloud, so that corporations can prioritize on what is most important – defending their most sensitive data and cloud-based applications without interfering with their normal operations. 5) Expect ransomware not to go away and get even more sophisticated Organizations in 2022 saw no let-up from ransomware threats, some of whom were attacked multiple times and I do not see any reason why this trend will change in 2023. Cyber criminals are getting more resourceful and savvier in their attempts to stay ahead of law enforcement, and I anticipate these attacks will only become more frequent as their perpetrators are proving more capable of infiltrating many organizations’ cyber defenses. In response, organizations will have to seek more technology solutions to protect data at the source. But that would not suffice. I think organizations will need to look beyond technological solutions and apply better preparedness strategies. Whether it be Zero Trust or something less overarching but more practical for an organization’s business needs, such as Micro-segmentation , it would ensure that threat-actors would not be able to access the data residing inside the security perimeter.

Cloud Security Sunburst Backdoor, Part II: DGA & The List of Victims 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 12/17/20 Published Previous Part of the analysis is available here . Next Part of the analysis is available here . Update from 19 December 2020: Prevasio would like to thank Zetalytics for providing us with an updated (larger) list of passive (historic) DNS queries for the domains generated by the malware. As described in the first part of our analysis, the DGA (Domain Generation Algorithm) of the Sunburst backdoor produces a domain name that may look like: fivu4vjamve5vfrtn2huov[.]appsync-api.us-west-2[.]avsvmcloud[.]com The first part of the domain name (before the first dot) consists of a 16-character random string, appended with an encoded computer’s domain name. This is the domain in which the local computer is registered. From the example string above, we can conclude that the encoded computer’s domain starts from the 17th character and up until the dot (highlighted in yellow): fivu4vjamve5vfrt n2huov In order to encode a local computer’s domain name, the malware uses one of 2 simple methods: Method 1 : a substitution table, if the domain name consists of small letters, digits, or special characters ‘-‘, ‘_’, ‘.’ Method 2 : base64 with a custom alphabet, in case of capital letters present in the domain name Method 1 In our example, the encoded domain name is “n2huov” . As it does not have any capital letters, the malware encodes it with a substitution table “rq3gsalt6u1iyfzop572d49bnx8cvmkewhj” . For each character in the domain name, the encoder replaces it with a character located in the substitution table four characters right from the original character. In order to decode the name back, all we have to do is to replace each encoded character with another character, located in the substitution table four characters left from the original character. To illustrate this method, imagine that the original substitution table is printed on a paper strip and then covered with a card with 6 perforated windows. Above each window, there is a sticker note with a number on it, to reflect the order of characters in the word “n2huov” , where ‘n’ is #1, ‘2’ is #2, ‘h’ is #3 and so on: Once the paper strip is pulled by 4 characters right, the perforated windows will reveal a different word underneath the card: “domain” , where ‘d’ is #1, ‘o’ is #2, ‘m’ is #3, etc.: A special case is reserved for such characters as ‘0’ , ‘-‘ , ‘_’ , ‘.’ . These characters are encoded with ‘0’ , followed with a character from the substitution table. An index of that character in the substitution table, divided by 4, provides an index within the string “0_-.” . The following snippet in C# illustrates how an encoded string can be decoded: static string decode_domain( string s) { string table = "rq3gsalt6u1iyfzop572d49bnx8cvmkewhj" ; string result = "" ; for ( int i = 0 ; i < s.Length; i++) { if (s[i] != '0' ) { result += table[(table.IndexOf(s[i]) + table.Length - 4 ) % table.Length]; } else { if (i < s.Length - 1 ) { if (table.Contains(s[i + 1 ])) { result += "0_-." [table.IndexOf(s[i + 1 ]) % 4 ]; } else { break ; } } i++; } } return result; } Method 2 This method is a standard base64 encoder with a custom alphabet “ph2eifo3n5utg1j8d94qrvbmk0sal76c” . Here is a snippet in C# that provides a decoder: public static string FromBase32String( string str) { string table = "ph2eifo3n5utg1j8d94qrvbmk0sal76c" ; int numBytes = str.Length * 5 / 8 ; byte [] bytes = new Byte[numBytes]; int bit_buffer; int currentCharIndex; int bits_in_buffer; if (str.Length < 3 ) { bytes[ 0 ] = ( byte )(table.IndexOf(str[ 0 ]) | table.IndexOf(str[ 1 ]) << 5 ); return System.Text.Encoding.UTF8.GetString(bytes); } bit_buffer = (table.IndexOf(str[ 0 ]) | table.IndexOf(str[ 1 ]) << 5 ); bits_in_buffer = 10 ; currentCharIndex = 2 ; for ( int i = 0 ; i < bytes.Length; i++) { bytes[i] = ( byte )bit_buffer; bit_buffer >>= 8 ; bits_in_buffer -= 8 ; while (bits_in_buffer < 8 && currentCharIndex < str.Length) { bit_buffer |= table.IndexOf(str[currentCharIndex++]) << bits_in_buffer; bits_in_buffer += 5 ; } } return System.Text.Encoding.UTF8.GetString(bytes); } When the malware encodes a domain using Method 2, it prepends the encrypted string with a double zero character: “00” . Following that, extracting a domain part of an encoded domain name (long form) is as simple as: static string get_domain_part( string s) { int i = s.IndexOf( ".appsync-api" ); if (i > 0 ) { s = s.Substring( 0 , i); if (s.Length > 16 ) { return s.Substring( 16 ); } } return "" ; } Once the domain part is extracted, the decoded domain name can be obtained by using Method 1 or Method 2, as explained above: if (domain.StartsWith( "00" )) { decoded = FromBase32String(domain.Substring( 2 )); } else { decoded = decode_domain(domain); } Decrypting the Victims’ Domain Names To see the decoder in action, let’s select 2 lists: List #1 Bambenek Consulting has provided a list of observed hostnames for the DGA domain. List #2 The second list has surfaced in a Paste bin paste , allegedly sourced from Zetalytics / Zonecruncher . NOTE: This list is fairly ‘noisy’, as it has non-decodable domain names. By feeding both lists to our decoder, we can now obtain a list of decoded domains, that could have been generated by the victims of the Sunburst backdoor. DISCLAIMER: It is not clear if the provided lists contain valid domain names that indeed belong to the victims. It is quite possible that the encoded domain names were produced by third-party tools, sandboxes, or by researchers that investigated and analysed the backdoor. The decoded domain names are provided purely as a reverse engineering exercise. The resulting list was manually processed to eliminate noise, and to exclude duplicate entries. Following that, we have made an attempt to map the obtained domain names to the company names, using Google search. Reader’s discretion is advised as such mappings could be inaccurate.
