Phishing Delivers JavaScript-Driven PureLogs Variant
🛡️ FortiGuard Labs uncovered a phishing campaign using purchase-order-themed emails to deliver a RAR attachment containing an obfuscated JavaScript file that drops and executes a PowerShell script. The PowerShell payload employs fileless techniques and process hollowing to load .NET modules into a suspended MsBuild.exe process, which then extracts and runs a downloader module. The downloader retrieves a fileless PureLogs plugin from a C2 server to harvest credentials, browser data, Discord tokens, and cryptocurrency wallet information before encrypting and exfiltrating it.
