For privilege escalation, Cobalt Strike can use named pipe impersonation to execute code as NT AUTHORITY \SYSTEM for unfettered access to an endpoint. In addition, adversaries may pivot between endpoints using WMI commands or SMB named pipe communication.

During lateral movement, Cobalt Strike beacons may execute as Windows services spawning PowerShell code or binaries that mirror the functions of PsExec. Cobalt Strike beacons evade defenses using Process Injection to execute malicious code within the memory space of native Windows binaries such as the Windows DLL Host rundll32.exe. Beacons allow adversaries to leverage multiple code delivery and execution methods during attacks. This capability demonstrates how Cobalt Strike fits into the threat model for nearly any organization.Ĭobalt Strike can generate and execute payloads in the form of an EXE, DLL, or shellcode these payloads are what Cobalt Strike refers to as a Beacon. Cobalt Strike is so common and reliable that adversaries create their own custom tooling to simply deploy the payloads, knowing that they will likely succeed if they can just get the payload past security controls. In other cases-such as 2020’s Solorigate supply chain compromise-adversaries created custom shellcode loaders to deploy Cobalt Strike payloads. In these cases, the adversaries often moved quickly, taking as little as two hours to reach their objective. It currently sits on the throne as the reigning champ of all malware toolkits. In incidents involving Bazar malware, we observed adversaries deploying Cobalt Strike payloads prior to Ryuk ransomware. The adoption of Cobalt Strike by global threat actors, and the framework’s use in hundreds of genuine intrusions, ransoms, and data breaches, shows that Beacon has fought its way to the top. It fills this need so well that multiple cybercrime enterprises and advanced threats have used the tool as part of compromises involving ransomware, data theft, and more.

Adversaries can buy Cobalt Strike, and there are older, cracked versions of Cobalt Strike freely available to adversaries online.Ĭobalt Strike fills adversaries’ needs by providing a reliable post-exploitation agent that works well and allows the adversaries to focus on other parts of the attack lifecycle. In 2020 we observed adversaries using Cobalt Strike during targeted attacks to steal payment card data, ransomware incidents to retain a foothold, red team engagements, and even incidents involving malicious document droppers. The tool integrates with functionality from multiple offensive security projects and can extend its functionality with aggressor scripts. leak and TinyNuke one as they continuously re-used and updated by the crimewave goops and live their own “life” after the leak," Kremez told BleepingComputer in a conversation.īleepingComputer has contacted Cobalt Strike and their parent company Help Systems to confirm the source code's authenticity but has not heard back.Cobalt Strike is an adversary simulation platform used by both red teams and adversaries. "The leak of the offensive tool opens the door for the additional crime actor enhancement of the tooling as it happens with the many malware tool leaks such as for Zeus 2.0.8.9.

"The possible re-compiled source code exposure of the “2019” Cobalt Strike 4.0 version has significant consequences for all defenders as it removes barriers of entry to obtaining the tool and essentially makes its easy for the crime groups to procure and modify code as needed on the fly." Since being posted, the repository has been forked 172 times, making it hard to contain the spread of the source code.Įven though it is not the original source code, it is enough to be of serious concern to security professionals.

If any of the byte patterns are found, then the parser will attempt to decode and print the configuration information of the Cobalt Strike beacon.

The person then fixed any dependencies and removed the license check, so that it could be compiled. Inspecting the parser code we can see that it looks for one of three byte patterns in order to identify the presence of a Cobalt Strike config. Community Kit is a central repository of extensions written by the user community to extend the capabilities of Cobalt Strike. Several excellent tools and scripts have been written and published, but they can be challenging to locate. Cobalt Strike license check commented outĪdvanced Intel's Vitali Kremez, who examined the source code, told BleepingComputer that he believes the Java code was manually decompiled. Cobalt Strike is a post-exploitation framework designed to be extended and customized by the user community.
