Cyber Threat Alert: Phishing Attacks Exploit Microsoft Visio Files

Security researchers from Perception Point have identified a new two-step phishing attack method using Microsoft Visio (.vsdx) files to evade detection and steal credentials. These attacks exploit the familiarity of Visio files in workplaces, embedding malicious URLs that lead victims to fake Microsoft 365 login pages. The attack involves instructing users to hold down the Ctrl key to access these URLs, bypassing automated security systems. Enhanced email security and two-factor authentication are recommended to mitigate these threats.
