Researchers uncovered a new malware campaign dubbed BeaverTail, a North Korean cyber espionage malware family primarily focusing on job seekers.

Initially identified as a JavaScript-based info stealer, it has since morphed into a native macOS version that pretends to be legitimate software like the MiroTalk video call service.

This malware is designed to steal confidential information from contaminated computers, including browser data and cryptocurrency wallets.

Cybersecurity researchers at Group-IB Threat Intelligence recently discovered that BeaverTail malware has been attacking Windows users via weaponized games.

Technical Analysis

Two new developments in the BeaverTail malware family were discovered by Group-IB’s cybersecurity specialists.

Firstly, they detected a new Windows version of BeaverTail, expanding the malware’s reach beyond its previous platforms. Secondly, and perhaps more alarmingly, they uncovered an evolved JavaScript variant of BeaverTail. 

This version circulates through innocent titles. It is built on ReactJS, a widely used JavaScript library for popular games.

These malicious applications are hidden inside NPM (Node Package Manager) packages and can easily be included in multiple development projects.

Through this sophisticated exploit, the Lazarus group has shown to be adaptive enough in their attempt to attack different operating systems and dev environments.

BeaverTail malware for Windows has been seen to disguise itself as a genuine conferencing app FCCCall.exe.

This is similar to an earlier Lazarus operation where the group trojanized the MiroTalk application.

Moreover, this most recent campaign was likely conducted between late July and early August, showing the group’s susceptibility to leveraging communication software in targeting host devices.

Two primary objectives remain the same for all BeaverTail versions, fetching cryptocurrency wallet information and downloading and executing the next-step payload, InvisibleFerret.

However, the malware’s developers broadened its scope as shown by the increasing number of browser extensions it targets.

BeaverTail now compromises a broader range of browser extensions including those previously mentioned such as kaikas, rabby, argent X, and Exodus web3 which suggests that its operators intend to capture a greater volume of victims’ cryptocurrency assets.
