How Stealer Logs Work

Infostealer malware is typically distributed through phishing emails, trojanized downloads, and malicious browser extensions. Once running on a device, it captures stored passwords, browser cookies, and session tokens in real time. The stolen data is compiled into a log file and sent to a Telegram channel or dark web forum, where it is shared freely or sold to other criminals for use in account takeover and fraud campaigns.
