Hackers Impersonate ReliaQuest Security Team Member to Steal SSO Credentials and MFA Access
ReliaQuest has disclosed a social engineering attack in which threat actors impersonated members of its security team to lure employees to a fraudulent single sign-on page.
The incident briefly exposed one employee identity, but ReliaQuest said its layered controls prevented access to internal applications, customer data, and business systems. The attack occurred on August 22, 2026, and used a targeted voice-phishing (vishing) approach.
The attackers registered a lookalike ReliaQuest domain and hosted a counterfeit SSO portal behind a content delivery network. This infrastructure was designed to appear legitimate while masking the phishing site’s underlying hosting environment.

Key Points that Matter
- Attackers are impersonating trusted cybersecurity personnel, using vishing to turn an organization’s own security processes against employees.
- Vishing is being used to gain initial access, exploiting human trust rather than vulnerabilities in traditional cybersecurity defenses.
- Voice Security can disrupt impersonation attacks earlier, reducing opportunities for malicious callers to reach, deceive, and compromise employees.
You Can Stop Voice-Based Threats
The Voice Channel has become the most exploited pathway for threat actors. Voice Security is no longer a nice to have, but a critical mandate.
Mutare’s Voice Security Platform defends the voice channel as critical infrastructure. Operating as a technical control at the network edge, it stops vishing, social engineering, spoofed calls, spam storms, and GenAI-powered attacks.
We understand that every organization is at a different stage of its Voice Security journey.
Some are just beginning to understand the risks. Others are evaluating solutions or validating technologies. Take a moment to check out Test Drive to choose your path towards understanding the voice security landscape and learning about a comprehensive defense solution.
