Formspring is the latest website to have suffered a security breach. Hackers compromised the password hashes of at least 420,000 users and posted them on the internet. Formspring says that the passwords of all 28 million users have been disabled. The firm also says that it has identified the security hole that allowed a hacker to breach its systems. To their credit, Formspring appears to have dealt with the security breach quickly and fairly transparently. There are undoubtedly lessons to be learnt from the hack and users would be wise to use unique, hard-to-guess passwords on different websites.”]
