ANY.RUN Exposes North Korean ‘Fake Interview’ Campaign: BeaverTail Loader Deploys InvisibleFerret Malware

DUBAI, DUBAI, UNITED ARAB EMIRATES, January 21, 2025 /EINPresswire.com/ -- ANY.RUN released technical research on a new wave of North Korean-linked malware campaigns disguised as job interviews. 𝗕𝗲𝗮𝘃𝗲𝗿𝗧𝗮𝗶𝗹, a JavaScript-based loader, deploys 𝗜𝗻𝘃𝗶𝘀𝗶𝗯𝗹𝗲𝗙𝗲𝗿𝗿𝗲𝘁, a Python stealer designed to steal crypto wallets, source code, and more. By posing coding challenges and software installs, attackers trick victims into downloading malicious components.

This campaign highlights how attackers disguise malware as ordinary job tasks, making it easy for even well-defended organizations to be caught off guard. Companies in tech and crypto should use advanced sandbox analysis for suspicious files and attachments. Regular monitoring of development environments and stronger access controls can help prevent these covert infiltration attempts and protect valuable corporate assets.
