What Is Stealc Malware?
Security Boulevard, Monday, January 5th, 2026
Stealc malware is an advanced information-stealing malware (infostealer) designed to secretly collect sensitive data from infected systems. Its primary focus is on web browsers, where it extracts saved passwords, cookies, autofill data, and session information.
In many cases, it also targets cryptocurrency wallets and system files, making it a high-risk threat for both individuals and organisations.
Stealc is distributed through a Malware-as-a-Service (MaaS) model, allowing cybercriminals to deploy it easily through phishing campaigns and malicious downloads.
