Cybercriminals are finding ways to bypass traditional security measures — not by exploiting software vulnerabilities, but by using something far simpler: stolen credentials. From social engineering and phishing to credential-stuffing attacks and buying credentials on the dark web, adversaries are increasingly relying on valid login details to move undetected within organizations, escalate privileges, and steal money or valuable information. According to CrowdStrike threat intelligence, identity-driven intrusions have become one of the most prevalent tactics used by both nation-state and eCrime actors. Five of the top ten MITRE ATT&CK® tactics observed were identity-based.1

Attackers know that once they have valid credentials, they can operate under the guise of legitimate users, bypassing perimeter defenses and extending their dwell time. The result? More damage, faster, and often without detection. This white paper breaks down five of the most notorious adversaries leveraging stolen credentials to infiltrate organizations. You’ll learn how they operate, their most effective techniques, and
— most importantly — how to protect against them. By understanding the tradecraft behind identity-based attacks, security teams can take a proactive approach to safeguarding their organizations from these evolving threats.
