A recent security study reveals that employees of failed startups are increasingly vulnerable to data theft, particularly through old Google logins. Researcher Dylan Ayrey highlighted that hackers can exploit defunct domains to access sensitive information, including Social Security numbers. Ayrey demonstrated this vulnerability by purchasing a failed startup's domain, successfully logging into multiple cloud services. Despite Google implementing security measures, flaws in OAuth configurations may still expose former employees. Ayrey estimates tens of thousands may be at risk, urging better shutdown practices for startups.
