Cryptocurrency Engineers Targeted by New macOS Malware ‘KandyKorn’

A newly identified macOS malware called ‘KandyKorn’ has been discovered in a cyber campaign linked to the North Korean hacking group Lazarus. The targets of this attack are blockchain engineers associated with a cryptocurrency exchange platform.

The attackers are using Discord channels to pose as members of the cryptocurrency community and distribute Python-based modules. These modules initiate a complex KandyKorn infection process.

Elastic Security, the organization that uncovered the attack, has linked it to Lazarus based on similarities with their previous campaigns, including techniques used, network infrastructure, code-signing certificates, and custom detection methods for Lazarus activity. 

The attack starts with social engineering on Discord, where victims are tricked into downloading a malicious ZIP archive named ‘Cross-platform Bridges.zip.’ This archive contains a Python script (‘Main.py’) that imports 13 modules, triggering the first payload, ‘Watcher.py.’ 

Watcher.py downloads and executes another Python script called ‘testSpeed.py’ and a file named ‘FinderTools’ from a Google Drive URL. FinderTools then fetches and runs an obfuscated binary named ‘SugarLoader,’ which appears as both .sld and .log Mach-O executables.
