The Behavioral Shift: Why Trusted Relationships Are the Newest Attack Surface

SecurityWeek

Recent research from Abnormal AI indicates a shift in how cyber attackers operate. Instead of relying on technical exploits, they are now targeting established workflows and the trust that exists within organizations. This means that attackers are using social engineering tactics to manipulate employees into compromise, effectively weaponizing the very relationships that businesses rely on. This trend raises concerns for companies as it highlights the vulnerability of internal processes and trust dynamics. Organizations need to reassess their security measures to address this evolving threat, as traditional defenses may not be sufficient to combat these new tactics.
