Cybersecurity researchers have uncovered a complex multi-stage attack using invoice-themed phishing emails to distribute various malware, including Venom RAT, Remcos RAT, and others. The attack utilizes BatCloak obfuscation and ScrubCrypt to deliver obfuscated batch scripts, ultimately executing malware such as Venom RAT and a wallet-stealing plugin. The attack demonstrates sophisticated obfuscation and evasion techniques.
Based on the meeting notes, it seems that cybersecurity researchers have uncovered a complex and sophisticated multi-stage attack involving the use of email phishing with invoice-themed decoys to deliver various types of malware, including Venom RAT, Remcos RAT, XWorm, NanoCore RAT, and a crypto wallet stealer. The attack leverages the use of Scalable Vector Graphics (SVG) file attachments to initiate the infection sequence and deploys malware obfuscation techniques such as BatCloak and ScrubCrypt to evade detection.
The attackers’ modus operandi includes the use of advanced obfuscation and evasion methods through phishing emails, obfuscated script files, and Guloader PowerShell to infiltrate and compromise victim systems. The attack campaign demonstrates versatility and adaptability by deploying plugins through different payloads, enabling the attackers to execute additional malicious activities and gather sensitive information from compromised systems.
This analysis provides valuable insights into the intricacies of the attack and underlines the importance of vigilance and robust cybersecurity measures to defend against such sophisticated threats.
