The discovery of a vulnerability related to old Google logins adds a new problem for employees of startups going bankrupt.

Dylan Ayrey, co-founder and CEO of Truffle Security, has disclosed a flaw related to Google OAuth, the technology behind "Connect with Google." Through this vulnerability, hackers can buy expired domains from failed start-ups, then recreate email addresses previously used by start-up employees. Using the "Connect with Google" option, hackers can access company-related cloud-based software, such as Slack, ChatGPT, Zoom, or HR systems.
