Executive Summary

This article discusses the growing trend of cybercriminals gaining access to corporate systems through legitimate credentials rather than traditional hacking techniques. Threat actors increasingly exploit weak, reused, or compromised passwords to bypass security controls, effectively 'walking through the front door' with valid credentials. This approach allows attackers to evade many security tools that focus on detecting malware or exploits rather than anomalous login behavior. The article emphasizes the importance of implementing strong authentication mechanisms, including multi-factor authentication (MFA), password hygiene policies, and continuous monitoring for credential-based threats. Organizations are advised to adopt a zero-trust security model and regularly audit credentials to reduce the attack surface. While no specific threat actors or malware families are discussed, the piece serves as a cautionary advisory on authentication security.

As bad actors often simply waltz through companies’ digital front doors with a key, here’s how to keep your own door locked tight
