What are infostealers exactly?

Malware that targets browsers and apps to steal logins, cookies, autofill — sold fresh on cybercrime shops.

Harden endpoints, monitor behavior, shorten sessions, go passwordless — layer it all. 800 words of wake-up call. Act.

Shadowserver clocked 2.3 billion credentials swiped by infostealers in 2023 alone. Simple breach monitoring? It's blind to the real action.
