LastPass is a popular online password manager that just had to do a hard password reset on a lot of their users. They noticed a network traffic anomaly, which was seen as a potential security issue. Users are being asked to change their master passwords.
Anomalies on the network could even be when an employee poked around or if an automated script executes a process. ?We?re going to be paranoid and assume the worst: that the data we stored in the database was somehow accessed,? stated the LastPass team on the company blog.
LastPass has also decided to roll out a technology called PBKDF2 using SHA-256 on their servers. This system should further mitigate any risks.
