As you may have heard already, the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI) released a joint... Cloud Security Drovorub’s Ability to Conceal C2 Traffic And Its Implications For 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 8/15/20 Published As you may have heard already, the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory about previously undisclosed Russian malware called Drovorub. According to the report, the malware is designed for Linux systems as part of its cyber espionage operations. Drovorub is a Linux malware toolset that consists of an implant coupled with a kernel module rootkit, a file transfer and port forwarding tool, and a Command and Control (C2) server. The name Drovorub originates from the Russian language. It is a complex word that consists of 2 roots (not the full words): “drov” and “rub” . The “o” in between is used to join both roots together. The root “drov” forms a noun “drova” , which translates to “firewood” , or “wood” . The root “rub” /ˈruːb/ forms a verb “rubit” , which translates to “to fell” , or “to chop” . Hence, the original meaning of this word is indeed a “woodcutter” . What the report omits, however, is that apart from the classic interpretation, there is also slang. In the Russian computer slang, the word “drova” is widely used to denote “drivers” . The word “rubit” also has other meanings in Russian. It may mean to kill, to disable, to switch off. In the Russian slang, “rubit” also means to understand something very well, to be professional in a specific field. It resonates with the English word “sharp” – to be able to cut through the problem. Hence, we have 3 possible interpretations of ‘ Drovorub ‘: someone who chops wood – “дроворуб” someone who disables other kernel-mode drivers – “тот, кто отрубает / рубит драйвера” someone who understands kernel-mode drivers very well – “тот, кто (хорошо) рубит в драйверах” Given that Drovorub does not disable other drivers, the last interpretation could be the intended one. In that case, “Drovorub” could be a code name of the project or even someone’s nickname. Let’s put aside the intricacies of the Russian translations and get a closer look into the report. DISCLAIMER Before we dive into some of the Drovorub analysis aspects, we need to make clear that neither FBI nor NSA has shared any hashes or any samples of Drovorub. Without the samples, it’s impossible to conduct a full reverse engineering analysis of the malware. Netfilter Hiding According to the report, the Drovorub-kernel module registers a Netfilter hook. A network packet filter with a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) is a common malware technique. It allows a backdoor to watch passively for certain magic packets or series of packets, to extract C2 traffic. What is interesting though, is that the driver also hooks the kernel’s nf_register_hook() function. The hook handler will register the original Netfilter hook, then un-register it, then re-register the kernel’s own Netfilter hook. According to the nf_register_hook() function in the Netfilter’s source , if two hooks have the same protocol family (e.g., PF_INET ), and the same hook identifier (e.g., NF_IP_INPUT ), the hook execution sequence is determined by priority. The hook list enumerator breaks at the position of an existing hook with a priority number elem->priority higher than the new hook’s priority number reg->priority : int nf_register_hook ( struct nf_hook_ops * reg) { struct nf_hook_ops * elem; int err; err = mutex_lock_interruptible( & nf_hook_mutex); if (err < 0 ) return err; list_for_each_entry(elem, & nf_hooks[reg -> pf][reg -> hooknum], list) { if (reg -> priority < elem -> priority) break ; } list_add_rcu( & reg -> list, elem -> list.prev); mutex_unlock( & nf_hook_mutex); ... return 0 ; } In that case, the new hook is inserted into the list, so that the higher-priority hook’s PREVIOUS link would point into the newly inserted hook. What happens if the new hook’s priority is also the same, such as NF_IP_PRI_FIRST – the maximum hook priority? In that case, the break condition will not be met, the list iterator list_for_each_entry will slide past the existing hook, and the new hook will be inserted after it as if the new hook’s priority was higher. By re-inserting its Netfilter hook in the hook handler of the nf_register_hook() function, the driver makes sure the Drovorub’s Netfilter hook will beat any other registered hook at the same hook number and with the same (maximum) priority. If the intercepted TCP packet does not belong to the hidden TCP connection, or if it’s destined to or originates from another process, hidden by Drovorub’s kernel-mode driver, the hook will return 5 ( NF_STOP ). Doing so will prevent other hooks from being called to process the same packet. Security Implications For Docker Containers Given that Drovorub toolset targets Linux and contains a port forwarding tool to route network traffic to other hosts on the compromised network, it would not be entirely unreasonable to assume that this toolset was detected in a client’s cloud infrastructure. According to Gartner’s prediction , in just two years, more than 75% of global organizations will be running cloud-native containerized applications in production, up from less than 30% today. Would the Drovorub toolset survive, if the client’s cloud infrastructure was running containerized applications? Would that facilitate the attack or would it disrupt it? Would it make the breach stealthier? To answer these questions, we have tested a different malicious toolset, CloudSnooper, reported earlier this year by Sophos. Just like Drovorub, CloudSnooper’s kernel-mode driver also relies on a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) to extract C2 traffic from the intercepted TCP packets. As seen in the FBI/NSA report, the Volatility framework was used to carve the Drovorub kernel module out of the host, running CentOS. In our little lab experiment, let’s also use CentOS host. To build a new Docker container image, let’s construct the following Dockerfile: FROM scratch ADD centos-7.4.1708-docker.tar.xz / ADD rootkit.ko / CMD [“/bin/bash”] The new image, built from scratch, will have the CentOS 7.4 installed. The kernel-mode rootkit will be added to its root directory. Let’s build an image from our Dockerfile, and call it ‘test’: [root@localhost 1]# docker build . -t test Sending build context to Docker daemon 43.6MB Step 1/4 : FROM scratch —> Step 2/4 : ADD centos-7.4.1708-docker.tar.xz / —> 0c3c322f2e28 Step 3/4 : ADD rootkit.ko / —> 5aaa26212769 Step 4/4 : CMD [“/bin/bash”] —> Running in 8e34940342a2 Removing intermediate container 8e34940342a2 —> 575e3875cdab Successfully built 575e3875cdab Successfully tagged test:latest Next, let’s execute our image interactively (with pseudo-TTY and STDIN ): docker run -it test The executed image will be waiting for our commands: [root@8921e4c7d45e /]# Next, let’s try to load the malicious kernel module: [root@8921e4c7d45e /]# insmod rootkit.ko The output of this command is: insmod: ERROR: could not insert module rootkit.ko: Operation not permitted The reason why it failed is that by default, Docker containers are ‘unprivileged’. Loading a kernel module from a docker container requires a special privilege that allows it doing so. Let’s repeat our experiment. This time, let’s execute our image either in a fully privileged mode or by enabling only one capability – a capability to load and unload kernel modules ( SYS_MODULE ). docker run -it –privileged test or docker run -it –cap-add SYS_MODULE test Let’s load our driver again: [root@547451b8bf87 /]# insmod rootkit.ko This time, the command is executed silently. Running lsmod command allows us to enlist the driver and to prove it was loaded just fine. A little magic here is to quit the docker container and then delete its image: docker rmi -f test Next, let’s execute lsmod again, only this time on the host. The output produced by lsmod will confirm the rootkit module is loaded on the host even after the container image is fully unloaded from memory and deleted! Let’s see what ports are open on the host: [root@localhost 1]# netstat -tulpn Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1044/sshd With the SSH server running on port 22 , let’s send a C2 ‘ping’ command to the rootkit over port 22 : [root@localhost 1]# python client.py 127.0.0.1 22 8080 rrootkit-negotiation: hello The ‘hello’ response from the rootkit proves it’s fully operational. The Netfilter hook detects a command concealed in a TCP packet transferred over port 22 , even though the host runs SSH server on port 22 . How was it possible that a rootkit loaded from a docker container ended up loaded on the host? The answer is simple: a docker container is not a virtual machine. Despite the namespace and ‘control groups’ isolation, it still relies on the same kernel as the host. Therefore, a kernel-mode rootkit loaded from inside a Docker container instantly compromises the host, thus allowing the attackers to compromise other containers that reside on the same host. It is true that by default, a Docker container is ‘unprivileged’ and hence, may not load kernel-mode drivers. However, if a host is compromised, or if a trojanized container image detects the presence of the SYS_MODULE capability (as required by many legitimate Docker containers), loading a kernel-mode rootkit on a host from inside a container becomes a trivial task. Detecting the SYS_MODULE capability ( cap_sys_module ) from inside the container: [root@80402f9c2e4c /]# capsh –print Current: = cap_chown, … cap_sys_module, … Conclusion This post is drawing a parallel between the recently reported Drovorub rootkit and CloudSnooper, a rootkit reported earlier this year. Allegedly built by different teams, both of these Linux rootkits have one mechanism in common: a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) and a toolset that enables tunneling of the traffic to other hosts within the same compromised cloud infrastructure. We are still hunting for the hashes and samples of Drovorub. Unfortunately, the YARA rules published by FBI/NSA cause False Positives. For example, the “Rule to detect Drovorub-server, Drovorub-agent, and Drovorub-client binaries based on unique strings and strings indicating statically linked libraries” enlists the following strings: “Poco” “Json” “OpenSSL” “clientid” “—–BEGIN” “—–END” “tunnel” The string “Poco” comes from the POCO C++ Libraries that are used for over 15 years. It is w-a-a-a-a-y too generic, even in combination with other generic strings. As a result, all these strings, along with the ELF header and a file size between 1MB and 10MB, produce a false hit on legitimate ARM libraries, such as a library used for GPS navigation on Android devices: f058ebb581f22882290b27725df94bb302b89504 56c36bfd4bbb1e3084e8e87657f02dbc4ba87755 Nevertheless, based on the information available today, our interest is naturally drawn to the security implications of these Linux rootkits for the Docker containers. Regardless of what security mechanisms may have been compromised, Docker containers contribute an additional attack surface, another opportunity for the attackers to compromise the hosts and other containers within the same organization. The scenario outlined in this post is purely hypothetical. There is no evidence that supports that Drovorub may have affected any containers. However, an increase in volume and sophistication of attacks against Linux-based cloud-native production environments, coupled with the increased proliferation of containers, suggests that such a scenario may, in fact, be plausible.

Tags Share this article 11/24/22 Published Organizations transitioning to the cloud require robust security concepts to protect their most critical assets, including business applications and sensitive data. Rony Moshkovitch, Prevasio’s co-founder, explains these concepts and why reinforcing a DevSecOps culture would help organizations strike the right balance between security and agility. In the post-COVID era, enterprise cloud adoption has grown rapidly. Per a 2022 security survey , over 98% of organizations use some form of cloud-based infrastructure. But 27% have also experienced a cloud security incident in the previous 12 months. So, what can organizations do to protect their critical business applications and sensitive data in the cloud? Why Consider Paved Road, Guardrails, and Least Privilege Access for Cloud Security It is in the organization’s best interest to allow developers to expedite the lifecycle of an application. At the same time, it’s the security teams’ job to facilitate this process in tandem with the developers to help them deliver a more secure application on time. As organizations migrate their applications and workloads to a multi-cloud platform, it’s incumbent to use a Shift left approach to DevSecOps. This enables security teams to build tools, and develop best practices and guidelines that enable the DevOps teams to effectively own the security process during the application development stage without spending time responding to risk and compliance violations issued by the security teams. This is where Paved Road, Guardrails and Least Privilege could add value to your DevSecOps. Concept 1: The Paved Road + Guardrails Approach Suppose your security team builds numerous tools, establishes best practices, and provides expert guidance. These resources enable your developers to use the cloud safely and protect all enterprise assets and data without spending all their time or energy on these tasks. They can achieve these objectives because the security team has built a “paved road” with strong “guardrails” for the entire organization to follow and adopt. By following and implementing good practices, such as building an asset inventory, creating safe templates, and conducting risk analyses for each cloud and cloud service, the security team enables developers to execute their own tasks quickly and safely. Security staff will implement strong controls that no one can violate or bypass. They will also clearly define a controlled exception process, so every exception is clearly tracked and accountability is always maintained. Over time, your organization may work with more cloud vendors and use more cloud services. In this expanding cloud landscape, the paved road and guardrails will allow users to do their jobs effectively in a security-controlled manner because security is already “baked in” to everything they work with. Moreover, they will be prevented from doing anything that may increase the organization’s risk of breaches, thus keeping you safe from the bad guys. How Paved Road Security and Guardrails Can Be Applied Successfully Example 1: Set Baked-in Security Controls Remember to bake security into reusable Terraform templates or AWS CloudFormation modules of paved roads. You may apply this tactic to provision new infrastructure, create new storage buckets, or adopt new cloud services. When you create a paved road and implement appropriate guardrails, all your golden modules and templates are already secure from the outset – safeguarding your assets and preventing undesirable security events. Example 2: Introducing Security Standardizations When creating resource functions with built-in security standards, developers should adhere to these standards to confidently configure required resources without introducing security issues into the cloud ecosystem. Example 3: Automating Security with Infrastructure as Code (IaC) IaC is a way to manage and provision new infrastructure by coding specifications instead of following manual processes. To create a paved road for IaC, the security team can introduce tagging to provision and track cloud resources. They can also incorporate strong security guardrails into the development environment to secure the new infrastructure right from the outset. Concept 2: The Principle of Least Privileged Access (PoLP) The Principle of Least Privilege Access (PoLP) is often synonymous with Zero Trust. PoLP is about ensuring that a user can only access the resources they need to complete a required task. The idea is to prevent the misuse of critical systems and data and reduce the attack surface to decrease the probability of breaches. How Can PoLP Be Applied Successfully Example 1: Ring-fencing critical assets This is the process of isolating specific “crown jewel” applications so that even if an attacker could make it into your environment, they would be unable to reach that data or application. As few people as possible would be given credentials that allow access, therefore following least privilege access rules. Crown jewel applications could be anything from where sensitive customer data is stored, to business-critical systems and processes. Example 2: Establishing Role Based Access Control (RABC) Based on the role that they hold at the company, RBAC or role-based access control allows specific access to certain data or applications, or parts of the network. This goes hand in hand with the principle of least privilege, and means that if credentials are stolen, the attackers are limited to what access the employee in question holds. As this is based on users, you could isolate privileged user sessions specifically to keep them with an extra layer of protection. Only if an administrator account or one with wide access privilege is stolen, would the business be in real trouble. Example 3: Isolate applications, tiers, users, or data This task is usually done with micro-segmentation, where specific applications, users, data, or any other element of the business is protected from an attack with internal, next-gen firewalls. Risk is reduced in a similar way to the examples above, where the requisite access needed is provided using the principle of least privilege to allow access to only those who need it, and no one else. In some situations, you might need to allow elevated privileges for a short period of time, for example during an emergency. Watch out for privilege creep, where users gain more access over time without any corrective oversight. Conclusion and Next Steps Paved Road, Guardrails and PoLP concepts are all essential for a strong cloud security posture. By adopting these concepts, your organization can move to the next stage of cloud security maturity and create a culture of security-minded responsibility at every level of the enterprise. The Prevasio cloud security platform allows you to apply these concepts across your entire cloud estate while securing your most critical applications.

Organizations no longer keep their data in one centralized location. Users and assets responsible for processing data may be located... Zero Trust How to Create a Zero Trust Network 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 2/12/24 Published Organizations no longer keep their data in one centralized location. Users and assets responsible for processing data may be located outside the network, and may share information with third-party vendors who are themselves removed from those external networks. The Zero Trust approach addresses this situation by treating every user, asset, and application as a potential attack vector whether it is authenticated or not. This means that everyone trying to access network resources will have to verify their identity, whether they are coming from inside the network or outside. What are the Zero Trust Principles and Concepts? The Zero Trust approach is made up of six core concepts that work together to mitigate network security risks and reduce the organization’s attack surface. 1. The principle of least privilege Under the Zero Trust model, network administrators do not provide users and assets with more network access than strictly necessary. Access to data is also revoked when it is no longer needed. This requires security teams to carefully manage user permissions , and to be able to manage permissions based on users’ identities or roles. The principle of least privilege secures the enterprise network ecosystem by limiting the amount of damage that can result from a single security failure. If an attacker compromises a user’s account, it won’t automatically gain access to a wide range of systems, tools, and workloads beyond what that account is provisioned for. This can also dramatically simplify the process of responding to security events, because no user or asset has access to assets beyond the scope of their work. 2. Continuous data monitoring and validation Zero trust policy assumes that there are attackers both inside and outside the network. To guarantee the confidentiality, integrity, and availability of network assets, it must continuously evaluate users and assets on the network. User identity and privileges must be checked periodically along with device identity and security. Organizations accomplish this in a variety of ways. Connection and login time-outs are one way to ensure periodic monitoring and validation since it requires users to re-authenticate even if they haven’t done anything suspicious. This helps protect against the risk of threat actors using credential-based attacks to impersonate authenticated users, as well as a variety of other attacks. 3. Device access control Organizations undergoing the Zero Trust journey must carefully manage and control the way users interact with endpoint devices. Zero Trust relies on verifying and authenticating user identities separately from the devices they use. For example, Zero Trust security tools must be able to distinguish between two different individuals using the same endpoint device. This approach requires fundamental changes to the way certain security tools work. For example, firewalls that allow or deny access to network assets based purely on IP address and port information aren’t sufficient. Most end users have more than one device at their disposal, and it’s common for mobile devices to change IP addresses. As a result, the cybersecurity tech stack needs to be able to grant and revoke permissions based on the user’s actual identity or role. 4. Network micro segmentation Network segmentation is a good security practice even outside the Zero Trust framework, but it takes on special significance when threats can come from inside and outside the network. Microsegmentation takes this one step further by breaking regular network segments down into small zones with their own sets of permissions and authorizations. These microsegments can be as small as a single asset, and an enterprise data center may have dozens of separately secured zones like these. Any user or asset with permission to access one zone will not necessarily have access to any of the others. Microsegmentation improves security resilience by making it harder for attackers to move between zones. 5. Detecting lateral movement Lateral movement is when threat actors move from one zone to another in the network. One of the benefits of micro segmentation is that threat actors must interact with security tools in order to move between different zones on the network. Even if the attackers are successful, their activities generate logs and audit trails that analysts can follow when investigating security incidents. Zero Trust architecture is designed to contain attackers and make it harder for them to move laterally through networks. When an attack is detected, the compromised asset can be quarantined from the rest of the network. Assets can be as small as individual devices or user accounts, or as large as entire network segments. The more granular your security architecture is, the more choices you have for detecting and preventing lateral movement on the network. 6. Multi-factor authentication (MFA) Passwords are a major problem for traditional security models, because most security tools automatically extend trust to anyone who knows the password. Once a malicious actor learns a privileged user’s login credentials, they can bypass most security checks by impersonating that user. Multi-factor authentication solves that problem by requiring users to provide more information. Knowing a password isn’t enough – users must authenticate by proving their identity in another way. These additional authentication factors can come in the form of biometrics, challenge/response protocols, or hardware-based verifications. How To Implement a Zero Trust Network 1. Map Out Your Attack Surface There is no one-size-fits-all solution for designing and implementing Zero Trust architecture. You must carefully define your organization’s attack surface and implement solutions that protect your most valuable assets. This will require a variety of tools, including firewalls, user access controls, permissions, and encryption. You will need to segment your network into individual zones and use microsegmentation to secure high-value and high-volume zones separately. Pay close attention to how your organization secures its most important assets and connections: Sensitive data . This might include customer and employee data, proprietary information, and intellectual property that you can’t allow threat actors to gain access to. It should benefit from the highest degree of security. Critical applications. These applications play a central role in your organization’s business processes, and must be protected against the risk of disruption. Many of them process sensitive data and must benefit from the same degree of security. Physical assets. This includes everything from customer-facing kiosks to hardware servers located in a data center. Access control is vital for preventing malicious actors from interacting with physical assets. Third-party services. Your organization relies on a network of partners and service providers, many of whom need privileged access to your data. Your Zero Trust policy must include safeguards against attacks that compromise third-party partners in your supply chain. 2. Implement Zero Trust Controls using Network Security Tools The next step in your Zero Trust journey is the implementation of security tools that allow you collect, analyze, and respond to user behaviors on your network. This may require the adjustment of your existing security tech stack, and the addition of new tools designed for Zero Trust use cases. Firewalls must be able to capture connection data beyond the traditional IP, port, and protocol data that most simple solutions rely on. The Zero Trust approach requires inspecting the identities of users and assets that connect with network assets, which requires more advanced firewall technology. This is possible with next generation firewall (NGFW) technology. VPNs may need to be reconfigured or replaced because they do not typically enforce the principle of least privilege. Usually, VPNs grant users access to the entire connected network – not just one small portion of it. In most cases, organizations pursuing Zero Trust stop using VPNs altogether because they no longer provide meaningful security benefits. Zero Trust Network Access (ZTNA) provides secure access to network resources while concealing network infrastructure and services. It is similar to a software-defined perimeter that dynamically responds to network changes and grants flexibility to security policies. ZTNA works by establishing one-to-one encrypted connections between network assets, making imprecise VPNs largely redundant. 3. Configure for Identity and Access Management Identity-based monitoring is one of the cornerstones of the Zero Trust approach. In order to accurately grant and revoke permissions to users and assets on the network, you must have some visibility into the identities behind the devices being used. Zero Trust networks verify user identities in a variety of ways. Some next-generation firewalls can distinguish between user traffic, device traffic, application traffic, and content. This allows the firewall to assign application sessions to individual users and devices, and inspect the data being transmitted between individuals on networks. In practice, this might mean configuring a firewall to compare outgoing content traffic with an encrypted list of login credentials. If a user accidentally logs onto a spoofed phishing website and enters their login credentials, the firewall can catch the data before it is transferred off the network. This would not be possible without the ability to distinguish between different types of traffic using next-generation firewall technology. Multi-factor authentication is also vital to identity and access management. A Zero Trust network should not automatically authenticate a user who presents the correct username and password combination to access a secure account. This does not prove the identity of the individual who owns the account – it only proves that the individual knows the username and password. Additional verification factors make it more likely that this person is, in fact, the owner of the account. 4. Create a Zero Trust Policy for Your IT Environment The process of implementing Zero Trust policies in cloud-native environments can be complex. Every third-party vendor and service provider has a role to play in establishing and maintaining Zero Trust. This often puts significant technical demands on third-party partners, which may require organizations to change their existing agreements. If a third-party partner cannot support Zero Trust, they can’t be allowed onto the network. The same is true for on-premises and data center environments, but with added emphasis on physical security and access control. Security leaders need to know who has physical access to servers and similar assets so they can conduct investigations into security incidents properly. Data centers need to implement strict controls on who interacts with protected equipment and how their access is supervised. How to Operationalize Zero Trust Your Zero Trust implementation will not automatically translate to an operational security context that you can immediately use. You will need to adopt security operations that reflect the Zero Trust strategy and launch adaptive security measures that address vulnerabilities in real-time. Gain visibility into your network. Your network perimeter is no longer strictly defined by its hardware. It consists of cloud resources, automated workflows, operating systems, and more. You won’t be able to enforce Zero Trust without gaining visibility into every aspect of your network environment. Monitor network infrastructure and traffic. Your security team will need to monitor and respond to access requests coming from inside and outside your network. This can lead to significant bottlenecks if your team is not equipped with solutions for automatically managing network traffic and access. Streamline detection and response. Zero Trust networks mitigate the risks of cyberattacks, malware, ransomware, and other potential threats, but it’s still up to individual security analysts to detect and investigate security incidents.
