Why This Matters

How Stealer Log Breaches Work

Infostealer malware including RedLine, Lumma, Vidar, and StealC lands on victim devices through cracked software, pirated games, malvertising, and phishing attachments. Once running, the malware scrapes saved browser passwords, cookies, autofill entries, and crypto wallet files, then uploads the log to the operator. Suppliers like LogLeader aggregate thousands of individual logs and market them on BreachForums.
