Organizations now manage thousands of human and non-human identities across cloud services, software-as-a-service applications, endpoints and remote environments. As hybrid working, Bring-Your-Own-Device (BYOD) and third-party access continue to expand, security teams are losing visibility over who has access to what and whether that access can be trusted.

Attackers are taking advantage of that complexity, as compromising an account is often faster and quieter than exploiting infrastructure vulnerabilities directly. For defenders, detecting malicious activity tied to a legitimate identity remains one of the biggest security challenges today.

So, what’s driving the rise in account takeover attacks, and how can organizations protect their identities?

Phishing the session, not the password

Credential abuse remains one of the most reliable ways for attackers to gain access to an organization, accounting for 22% of breaches in 2025. Attackers obtain usernames and passwords through infostealer malware, phishing campaigns or credential dumps from previous breaches.
