✍️ Technical Analysis Published: Telegram Account Compromised, Wallet Swapped: How Does macOS Malware Break Through Your Defenses?
Our latest investigation reconstructs how a single malware sample chains together Telegram session theft, wallet database exfiltration, offline decryption and fake wallet applications into a complete account takeover workflow.
Our analysis shows:
1️⃣Stolen Telegram Desktop and Telegram for macOS session files can be restored on another Mac without re-entering a phone number, verification code or 2FA password
2️⃣For Telegram for macOS, even after server-side security mechanisms respond, cached chat history may remain accessible instead of being cleared by a forced logout
3️⃣Wallet databases can be paired with passwords collected from Keychain, browsers and Apple Notes for offline decryption, without interacting with the victim's device
4️⃣Fake Ledger and Trezor desktop apps are actually WKWebView-based loaders that replace trusted wallet interfaces with attacker-controlled phishing pages
The malware doesn't rely on a single technique—it combines authenticated sessions, encrypted wallet data and credential material into one attack chain.
💡 Defense tip: Protect your local Telegram session by enabling a Telegram Passcode and using a strong, unique password.
