Home media streaming service Plex has warned users to reset their passwords following a suspected hack that could affect up to up to half of its 30 million users. Plex has apologised and said that it has discovered how the threat actor accessed the system and is tightening security to prevent future incidents. This story is a reminder to regularly update passwords, not to share passwords, and to make use of other extra layers of security around passwords such as 2FA. In other worrying password-related news, password management platform LastPass has confirmed that it too has been compromised, although it insists that passwords, encrypted password vaults, and other sensitive data are safe.
