Failed Social Engineering Attack on ReliaQuest by ShinyHunters On August 22, 2026, cybersecurity firm ReliaQuest experienced a social engineering attack where hackers impersonated security team members to trick an employee into accessing a fake single sign-on (SSO) page. The attackers used a lookalike domain, reliaquest.claims, and successfully obtained temporary, view-only access to the employee's identity dashboard after the employee entered their credentials and approved an MFA push notification. However, ReliaQuest's device-trust controls prevented further access to applications and systems. The company confirmed that no customer data was compromised and that the attacker's session was terminated promptly. ShinyHunters later claimed responsibility for the attack, but ReliaQuest disputed the extent of the breach, stating that no systems or sensitive data were accessed.
