To MFA or Not To MFA: How Multi-factor Authentication Saves the SMB | Huntress

**Executive Summary:** This blog explains that MFA dramatically raises the technical barrier for account takeover—accounts without MFA are readily compromised via credential theft (brute force, password spraying, credential dumps), while accounts protected by MFA force attackers to adopt session/token theft techniques (Adversary-in-the-Middle proxies like Evilginx and passive token resale enabled by infostealer malware such as Redline). Focused on SMBs, the author recommends enforcing any available MFA and hardening endpoints to prevent credential-stealer delivery and token reuse.
