New CMoon USB worm targets Russians in data theft attacks

August 7, 2024 at 05:30PM

The ‘CMoon’ self-spreading worm, discovered by Kaspersky researchers, targets high-value entities in Russia via a compromised gas supply company website. It employs malicious document links to distribute itself and exhibits various functionalities such as info-stealing, DDoS attacks, and self-propagation. Kaspersky advises vigilance due to its potential for further distribution.

Based on the meeting notes, the key takeaways are:

– A new self-spreading worm named ‘CMoon’ has been distributed in Russia since early July 2024 via a compromised gas supply company website.
– CMoon can steal account credentials and other data, perform a broad range of functions such as loading additional payloads, capturing screenshots, and launching DDoS attacks.
– The distribution mechanism involves users clicking on links to regulatory documents on the gas supply company’s website, which were replaced by links to malicious executables containing the CMoon payload.
– Once a system is infected, CMoon copies itself to a newly created folder, secures persistence between reboots, monitors and manipulates files on connected USB drives, and targets specific files and directories for stealing data.
– Stolen files and system information are sent to an external server for decryption and verification of integrity using an MD5 hash.
– Kaspersky researchers warn of the possibility of CMoon being distributed through other sites and emphasize the importance of vigilance due to its autonomous spreading capabilities.
