A recent cyber threat has emerged with a new hacker group dropping multiple strains of malware onto victims’ computers simultaneously. Instead of using traditional single-malware attacks, this group, known as Unfurling Hemlock, has adopted a tactic called “malware cluster bombs.”
Unfurling Hemlock’s attacks involve deploying a series of malware samples in a single executable file, ultimately leading to an array of malicious software infiltrating the target system. These attacks have impacted various countries globally, with a focus on the U.S., according to cybersecurity experts.
The initial stage of the attack typically begins with malicious emails or loaders containing an executable file named “WEXTRACT.EXE.” This file acts as the carrier for the malware cluster bomb, containing nested compressed cabinet files that unpack to release different malware variants.
Among the types of malware dropped in these attacks are info-stealers, botnets, and backdoors, including popular strains like the Redline stealer. While the group’s motives for these attacks remain unclear, speculations suggest data harvesting and potential sales to other malicious entities.
To protect against such multi-malware assaults, users are advised to exercise caution when downloading files and remain vigilant against phishing emails or suspicious attachments. Utilizing reliable antivirus software is also crucial in detecting and preventing malware infections, ensuring a secure digital environment.
