The MFA Gaps Attackers Are Still Exploiting
Cybercriminals continue to bypass multi-factor authentication by targeting systems that still rely on passwords alone, such as VPNs, RDP and Windows endpoints.
Attackers are exploiting gaps in multi-factor authentication coverage, using stolen credentials to gain access to VPNs, RDP and Windows systems that still depend solely on passwords.
Many organizations have rolled out MFA for cloud applications but often leave legacy on‑premises services unprotected, creating a blind spot that threat actors actively hunt.
Stolen credentials are typically obtained through phishing campaigns, credential stuffing or purchased from underground markets, then reused against the unprotected entry points.
Because cloud‑only MFA does not stop attackers who pivot inside the network, these gaps allow lateral movement, data theft and ransomware deployment.
To close the authentication gap, experts recommend enforcing MFA everywhere, adopting zero‑trust principles, monitoring authentication logs for anomalies, upgrading legacy systems to support modern MFA and using conditional access policies.
