Google OAuth Vulnerability Exposes Millions via Failed Startup Domains

New research has uncovered a vulnerability in Google's "Sign in with Google" authentication process that leverages a domain ownership loophole to access sensitive information.
According to Dylan Ayrey, co-founder and CEO of Truffle Security, Google's OAuth login lacks safeguards against attackers who purchase the expired domains of defunct startups. By doing so, they can recreate former employee email accounts.
"Although these attackers can't retrieve past email data, they can exploit these accounts to log into various SaaS platforms previously used by the organization," Ayrey explained in a report released Monday.
Microsoft brings in 2025 with over 159 vulnerabilities!

Microsoft's January update delivers fixes for a record-breaking 159 vulnerabilities, including eight zero-day flaws—three of which are currently being actively exploited by attackers.
This release marks Microsoft's largest patch update to date and is particularly significant because three of the vulnerabilities were identified by an artificial intelligence (AI) platform.
Microsoft classified 10 of these vulnerabilities as critically severe, with the remaining labeled as important. The patches cover a wide range of Microsoft products, including Windows OS, Microsoft Office, .NET, Azure, Kerberos, and Windows Hyper-V. The update addresses over 20 remote code execution (RCE) vulnerabilities, nearly as many elevation-of-privilege issues, and various other flaws related to denial-of-service, security bypass, spoofing, and information disclosure.
