Typhon Reborn With New Capabilities

Summary: Cyble Research Labs uncovered Typhon Stealer, a crypto miner and stealer sold for hire, in early August 2022, and the author soon released an updated version called Typhon Reborn with more anti-analysis techniques and improved stealer and file grabber features. The author advertised it on an underground website and Telegram channel at $100 for a lifetime subscription, with a compressed payload of roughly 2.3 MB, while removing the keylogger, clipper, miner and worm features and adding a crypto-extension stealer for Google Chrome and Microsoft Edge.

Key Takeaway: A $100 lifetime stealer with a configurable builder lowers the skill needed to steal crypto wallets and Wi-Fi passwords, and its MeltSelf routine deletes itself from disk whenever it detects analysis tools, sandbox usernames, or a debug flag.
