What to Do After an Infostealer Infection?

Summary

Mike explains that infostealer malware may be disguised as a free download, such as a software crack, game cheat, or fake driver. When run, it can steal saved browser credentials, browsing history, and cookie sessions, send the data to remote storage, and then delete itself—potentially leaving little obvious sign of infection.

He recommends three remediation steps:

1. Identify and delete the suspicious executable, and do not run it again.
2. Sign out of or revoke active cookie sessions. Stolen session cookies may let attackers bypass two-factor authentication.
3. Review what data was exposed and change passwords for affected accounts, one site at a time.

The video also promotes purchasing AlertsBar’s full reports. Its claim that these steps make users safe should be understood as the presenter’s assurance, not a guarantee.
