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.

Proper firewall configuration is essential for a secure network Explore how to overcome challenges and learn tips for effective firewall configuration Firewall configuration: What is it? How does it work? Firewalls can greatly increase the security of enterprise networks, and enable organizations to protect their assets and data from malicious actors. But for this, proper firewall configuration is essential. Firewall configuration involves configuring domain names and Internet Protocol (IP) addresses and completing several other actions to keep firewalls secure. Firewall policy configuration is based on network types called “profiles” that can be set up with security rules to prevent cyber attacks. Schedule a demo Watch a video Firewall configuration challenges Configuring firewalls can raise many challenges Finding the right firewall It can be overwhelming to decide between a hardware or software firewall, so make sure you first determine your business needs and network configuration. Software firewalls can protect individual machines against harmful traffic; hardware firewalls are suitable for protecting enterprise networks. Broad firewall policy configurations During firewall setup, broad approvals policies that allow traffic from any source to any destination can expose the network to several security risks. It’s safer to implement narrow permissions from the start by following the Principle of Least Privilege (POLP). These firewall rule configurations can be widened later as required. Non-standard authentication With non-standard authentication methods, your firewall could accept weaker passwords or place less stringent limits on the number of login attempts allowed. This increases the risk of cybersecurity breaches. For safety, use only standard authentication methods. Open ports and risky management services Cybercriminals leverage open firewall ports and dynamic routing protocols to penetrate and exploit enterprise networks. Disable open ports at the time of firewall configuration. Other open ports should be adequately protected. Inadequate firewall monitoring If firewalls are not monitored, you may miss signs of unusual traffic that could indicate the presence of cyber attackers. Always monitor and log outputs from security devices so you will be alerted if you’re under attack. If an attacker does break through, alerts reduce the time to response. Guest or public networks: Use this profile when the system is connected to a public network. It’s best to set restrictive access because the other systems on the network could be potentially harmful. Private networks: Use this profile when connected to a network in workgroup mode. Set access to medium levels since the other systems can be mostly trusted. Domain networks: This profile is used when networks are connected to an Active Directory (AD) domain. A group policy controls the firewall settings. What are the network profiles for firewall configuration? A typical enterprise-level network is segregated into multiple security zones or “rings”: Ring 1: The Internet Edge Ring 2: The Backbone Edge Ring 3: The Asset Network Edge Ring 4: Local Host Security These zones are a logical way to group the firewall’s physical and virtual interfaces, and control traffic. Traffic can flow freely within a zone, but not between different zones until you define and allow it within the firewall policy configuration. In general, more zones means a more secure network What is the role of security zones in firewall settings? Yes, you can create a filter with a list of words, phrases and variations to be blocked. Configure your firewall settings to “sniff” each packet of traffic for an exact match of this text. Can I configure my firewall to block specific words or phrases? For each network profile, a firewall displays status information like: Profile currently in use Firewall state (On or Off) Incoming connections and current policy Active networks Notification state What information does a firewall display for each network profile? You can set firewall filters for all these protocols: Internet Protocol (IP) to deliver information over the Internet Transmission Control Protocol (TCP) to break apart and reconstruct information over the Internet HyperText Transfer Protocol (HTTP) for web pages User Datagram Protocol (UDP) for information that requires no user response File Transfer Protocol (FTP) to upload/download files Simple Mail Transport Protocol (SMTP) for sending text-based information via email Simple Network Management Protocol (SNMP) to collect system information from a remote computer Telnet to perform commands on a remote computer What are the protocols you can set firewall filters for? Here’s a 6-step secure firewall setup process: Secure the firewall Update with the latest firmware Replace default passwords with strong, unique passwords Avoid using shared user accounts Disable Simple Network Management Protocol (SNMP) or configure it securely Restrict incoming/outgoing traffic for TCP Create firewall zones Group assets into zones based on functions and risk levels Set up the IP address structure to assign zones to firewall interfaces Configure Access Control Lists (ACLs) Make them specific to the source and destination port numbers and IP addresses Create a “deny all” rule to filter out unapproved traffic Create an ACL (inbound/outbound) for each interface and sub-interface Disable admin interfaces from public access Disable unencrypted firewall management protocols Configure firewall logging Critical if PCI DSS compliance is a requirement Disable extra/unused services Test the firewall configuration Ensure the correct traffic is being blocked Perform penetration testing and vulnerability scanning Securely back up the configuration After you complete the firewall setup, manage and monitor it continuously to ensure that it functions as intended What are the firewall configuration steps?

Firewall management services are companies that provide maintenance and management over companies’ firewall and network security infrastructure Firewall management services
Proactive network security Firewall management services (also known as MSSPs, or Managed Security Service Providers ) , are third-party providers that manage and maintain your firewall infrastructure. They operate, administer, monitor and maintain the infrastructure. Firewall management companies also help establish, maintain, and monitor firewall rules. Schedule a demo Case study Firewall management services Common questions about firewall management services What are managed firewall services? A managed firewall are the services around firewalls that ensure that firewalls have clear and well-maintained firewall policy rules, firewalls are proactively patched and updated when needed, and that there is proactive monitoring and auditing. What does a firewall management company do? Firewalls are managed by MSSPs. By using a managed firewall service, organizations get intrusion protection and rapid response to any security incidents. What are firewall service providers and what do they do? Firewall service providers can provide firewalls as a cloud service (FWaaS). Firewall as a Service (FWaaS) moves firewall functionality to the cloud instead of the traditional network perimeter. This allows firewalls to be deployed anywhere in the world and support geographically dispersed remote workforces. How do MSSPs and managed firewall services relate to network firewall security management? MSSPs handle network policy security management in-house. It is the responsibility of the MSSPs to institute, maintain, and modify firewall rules and manage the entire change management process end-to-end. MSSPs can use network security management solutions to manage multiple clients and accelerate visibility, automation, compliance monitoring, and change management. Resources Learn from the experts.

Some NIST data security standards include NIST 800-53, which offers security controls and privacy controls in the areas of application security, mobile, and cloud computing, and supply chain security, NIST 800-53/FI, which establishes standards to implement FISMA , NIST 800-30, which provides guidelines for conducting risk assessments, NIST 800-171, pertaining to the physical security of data centers, and ISO 27001 . White Paper Solution Overview Understanding the NIST Cybersecurity Framework One of the most widely used NIST security standard is the NIST Cybersecurity Framework (CSF). This internationally recognized framework offers voluntary guidance, based on existing standards, guidelines, and practices for organizations to better manage and reduce cybersecurity risk. It provides companies with an easy-to-understand common language for talking about cybersecurity risk, no matter where they are on the org chart – from the server room to the board room. The NIST Cybersecurity Framework identifies five core functions: Identify Protect Detect Respond Recover The framework describes desired outcomes that are understandable by everyone, applies to any kind of risk management, defines the entire breath of cybersecurity, and spans both prevention and reaction. Webinar Infographic FAQ ABOUT NIST CYBERSECURITY STANDARDS Understanding NIST Cybersecurity Standards is a crucial part of your network security compliance posture. There are many international regulations that your organization needs to be compliant with, including HIPPA , PCI DSS , GDPR , NIST , ISO 27001, and Sarbanes-Oxley (SOX). Do the NIST Cybersecurity Standards provide a checklist of what all organization should do? No. The framework provides guidance that should be customized by different organizations to best suit their unique risks, situations, and needs. Organizations have different risks, threats, vulnerabilities, and risk tolerance. They will also differ in how they implement the practices in the framework. It should not be implemented as an un-customized checklist or take a one-size-fits-all approach How does my firewall management help with NIST Standards and the NIST Cybersecurity Framework? NIST Special Publication 800-41 establishes guidelines for firewalls and firewall policies, which govern standards and best practices for firewall policy management. According to the guidelines, an organization’s firewall policies should be based on a comprehensive risk-assessment. Firewall policies should be based on blocking all inbound and outbound traffic (“Default Deny”), with exceptions made for desired traffic. Policies should consider the source and destination of the traffic, in addition to the content. Many types of IPv4 traffic, such as those with invalid or private addresses, should be blocked by default. Organizations also should have policies for handling incoming and outgoing IPv6 traffic. Organizations should also determine which applications may send traffic into and out of its network and make firewall policies to block traffic for other applications. According to the guidelines (5.2.2), “if multiple firewalls need to have the same rules or a common subset of rules, those rules should be synchronized across the firewalls. This is usually done in a vendor-specific fashion.” AlgoSec provides out-of-the-box regulatory compliance reports for NIST SP 800-41. What about NIST SP 800-53? NIST SP 800-53, Security and Privacy Controls for Federal Information Systems and Organizations, relates to systems, including firewalls, that monitor and control at the external boundaries of the network and systems that connect to parts of the network. It provides extensive standards for firewall management. AlgoSec provides out-of-the-box regulatory compliance reports for NIST SP 800-53. Do NIST standards also relate to FISMA compliance? How AlgoSec Helps with NIST Standards? FISMA sets out guidelines for managing information security that must be followed for all information systems used or operated by a U.S. federal government agency in the executive or legislative branches, or by a contractor or other organization on behalf of a federal agency in those branches. By following NIST Cybersecurity Guidelines and NIST’s guidelines for firewalls and firewall policies, organizations get closer to FISMA compliance. AlgoSec helps identify traffic flows and associate it with the relevant business applications, and design firewall policies that work across your hybrid network, all with zero-touch automation to reduce the chances of manual misconfigurations. AlgoSec also helps manage and synchronize rules across the multi-vendor estate, so there is holistic and unified management across a network made up of multiple vendors. By using AlgoSec, organizations can be sure that their security management practices follow best practices such as NIST standards. AlgoSec automatically generates pre-populated, audit-ready compliance reports for leading industry regulations, including NIST SP 800-53, NIST SP 800-41, SOX, GLBA, PCI DSS, and ISO 27001— which helps reduce audit preparation efforts and costs. AlgoSec also uncovers gaps in organization’s compliance posture and proactively checks every change for compliance violations. AlgoSec also provides daily audit and compliance reporting across the entire heterogeneous network estate. What are some common regulations that customers must be compliance with?
