Copy all of the Java Meterpreter files, unchanged, into the folder where the extracted Cobalt Strike lives. This Sleep code will silently run Java Meterpreter in its own thread.
Consult the Sleep manual for different ways to obfuscate this code. The opposite of unzip is zip. Use this program to package the extracted Cobalt Strike files into one zip file. The cracked trial filename should end in. Cracked trials of Cobalt Strike trials are available on many websites.
I have never downloaded one and I do not intend to. There is a way to get a clean copy of Cobalt Strike though. Download a 21 day trial through the official website. After unzip, all of the Cobalt Strike files will spill out: Java applications consist of. In these cases, the preceding malware typically loads and executes Cobalt Strike. After Cobalt Strike has been executed and a Beacon established for C2 communication, actors have been observed attempting to enumerate network connections and dumping Active Directory credentials as they try to move laterally to a network resource such as a Domain Controller, allowing for deployment of ransomware to all networked systems.
For example, the Cobalt Strike documentation states :. Use the net dclist command to find the Domain Controller for the domain the target is joined to. Use the net view command to find targets on the domain the target is joined to. In addition to network discovery and credential dumping, Cobalt Strike Beacon also has the capability to elevate privileges, load and execute additional tools, and to inject these functions into existing running host processes to attempt to avoid detection.
Proofpoint researchers anticipate Cobalt Strike will continue to be a commonly used tool in threat actor toolsets. According to internal data, tens of thousands of organizations have already been targeted with Cobalt Strike, based on observed campaigns. We expect this number to increase in Cobalt Strike is a useful tool, for legitimate security researchers and threat actors alike. Its malleability coupled with its usability makes it a robust and effective tool for siphoning data, moving laterally, and loading additional malware payloads.
Cobalt Strike is not the only red team tool appearing more often in Proofpoint data. Others include Mythic, Meterpreter, and the Veil Framework.
The use of publicly available tooling aligns with a broader trend observed by Proofpoint: Threat actors are using as many legitimate tools as possible, including executing Windows processes like PowerShell and WMI; injecting malicious code into legitimate binaries; and frequently using allowable services like Dropbox, Google Drive, SendGrid, and Constant Contact to host and distribute malware. January — Odinaff: New Trojan used in high level financial attacks.
October — Leviathan: Espionage actor spearphishes maritime and defense targets. Proofpoint Emerging Threats includes robust detections for Cobalt Strike. The following are a sample of our detections as they relate to the behaviors described in this report. Threat Insight. June 29, Selena Larson and Daniel Blackford.
