This morning, many Vietnamese Facebook users woke up to a surprising message, notifying them that their accounts had been locked and requesting that they change their passwords, reports VN Express.
The message read:
“We’ve detected suspicious activity on your Facebook account and have temporarily locked it as a security precaution.”
After filling out a CAPCHA code and changing their passwords, users were able to log into Facebook normally.
This is not the first time Facebook has asked its users to change their password. The social network sent similar messages in June 2013 and November 2013, suggesting that account holders use a secure password, different from the one they use for other websites.
This morning’s message appeared after the information security company, Hold Security, informed Facebook that a hacker group called CyberVor had collected 1.2 billion passwords and 500 million emails on 420,000 websites worldwide, reputed to be the biggest information hack in the history of the internet.
If your passwords look something like - 123456 – it may be time to change things up.
