The Russian threat actor RomCom is linked to recent cyber attacks on Ukrainian government agencies and Polish entities, utilizing a variant of the RomCom RAT called SingleCamper. Targeting espionage, the group employs various malware tools, often starting with spear-phishing tactics, to establish long-term network access and exfiltrate data.
Here are the key takeaways from the meeting notes regarding the RomCom threat actor:
1. **Threat Actor Identification**: The Russian threat actor known as RomCom, also tracked as Storm-0978, has been linked to a series of cyber attacks targeting Ukrainian government agencies and unidentified Polish entities since late 2023.
2. **Malware Variant**: A new variant of the RomCom RAT called SingleCamper (also known as SnipBot or RomCom 5.0) is being utilized. This version has unique characteristics, such as being loaded directly from the registry into memory and using a loopback address for communication.
3. **Historical Operations**: RomCom has been involved in various operations including ransomware, extortion, and credential gathering since its emergence in 2022, indicating a multi-motivational strategy.
4. **Increased Attack Activity**: There has been an uptick in the frequency of attacks in recent months, suggesting a focus on establishing long-term access to compromised networks and data exfiltration for espionage purposes.
5. **Tool and Infrastructure Expansion**: The threat actor is expanding its toolkit and infrastructure, developing malware in multiple programming languages, such as C++ (ShadyHammock), Rust (DustyHammock), Go (GLUEEGG), and Lua (DROPCLUE).
6. **Attack Methodology**: The attack vectors commence with spear-phishing emails that deliver a downloader (coded in C++ or Rust), followed by the deployment of backdoors (ShadyHammock and DustyHammock). A decoy document is presented to distract the recipient.
7. **Backdoor Functionality**: DustyHammock connects to a command-and-control server and runs commands, while ShadyHammock launches SingleCamper and monitors for incoming commands.
8. **Post-Compromise Activities**: SingleCamper engages in significant activities post-compromise, including establishing remote communication, network reconnaissance, lateral movement, user/system discovery, and data exfiltration.
9. **Espionage and Potential Ransomware Pivot**: The dual strategy of UAT-5647 aims to first establish long-term access for data exfiltration and potentially shift to ransomware deployment for financial gain.
10. **Targeting Context**: The targeting of Polish entities may be inferred from the keyboard language checks performed by the malware.
These points encapsulate the current threat landscape associated with the RomCom threat actor and their strategic operations.
