🧀 Update on MintsLoader: a thread 🔽
MintsLoader is a JavaScript/PowerShell loader that was first detailed by OCD in 2024.
A new version has been around at least since early-June 2025.

Historically, new MintsLoader JS samples were easy to find because the obfuscation strings consistently used text from the book Andrew Melville by William Morison. The associated infrastructure could be tracked thanks to specific patterns and campaign IDs in the C2 URLs.

These detection opportunities were presented during the Botconf 2025. The new version has removed these notable behaviours and is seen in campaign with fake invoices lures.
