Attack Methodology:
The attackers used an email that seemed to come from a trusted source, inviting users to collaborate on a Google Document. The link redirected users to a fake Google login page that closely mimicked the legitimate one. Upon entering their credentials, users unknowingly provided their login information to the attackers.
Technical Details:
The phishing emails were crafted using social engineering techniques to exploit trust. Attackers utilized OAuth 2.0 to create a legitimate-looking request for access, which made the scam more convincing.
Impact and Response:
Google quickly responded by suspending the malicious accounts and enhancing their phishing detection algorithms. Users were educated on recognizing suspicious links and the importance of verifying the sender’s email address.
