Infostealer Intelligence

What is an Infostealer?
An infostealer is a type of malware designed to silently harvest credentials, session cookies, browser-saved passwords, and other sensitive data from infected machines. Stolen records are packaged into logs and sold on underground markets, giving threat actors ready-made access to corporate systems — often before a ransomware attack is ever launched. The data on this page correlates known infostealer-compromised credentials with ransomware victims tracked by this platform, revealing the credential-exposure footprint that preceded or accompanied each attack.
