1,192 Hotmail Victims Targeted Through a Known Telegram Criminal Network

How Stealer Log Breaches Work

Stealer logs are produced when infostealer malware infects a victim's device, captures browser-stored credentials and session data, then transmits everything to criminal infrastructure. Operators like MegaCloud compile, name, and redistribute these files to their Telegram communities, where subscribers use the credentials for account takeover and fraud.
