vishing attacks

Vishing attacks, or voice phishing, are a growing threat where attackers use phone calls or collaboration platforms like Microsoft Teams to trick victims into revealing credentials or granting remote access. Recent incidents detailed on WindowsForum highlight how threat actors, including groups linked to ShinyHunters, combine real-time social engineering with convincing credential-harvesting pages to compromise SSO-protected SaaS accounts and enroll attacker-controlled MFA devices. Microsoft's own incident responders have documented cases where a routine Teams support call led to full compromise and multi-stage intrusion. These attacks bypass traditional security measures by targeting human trust, making awareness and verification protocols critical for enterprise IT and security teams.
