Frequently Asked Questions

What is account takeover?

Account takeover is when an attacker gains access to a legitimate user’s account, often using stolen credentials, and then misuses it.

What is credential stuffing?

Credential stuffing uses bots to try leaked username and password pairs across many sites, exploiting password reuse.

Does MFA stop account takeover?

MFA greatly reduces risk, but attackers use phishing, SIM swaps and MFA fatigue, so behavioral detection is still important.
