Many Facebook users in Vietnam are asked to change their passwords.
On the morning of August 12, many Facebook users in Vietnam suddenly received a notification that their accounts were temporarily locked.
"We've detected suspicious activity on your account and are temporarily blocking it to keep it safe. It looks like you visited a website that looked like Facebook and entered your password. This type of attack is called phishing. Follow these steps to log back in," Facebook advised.

After entering the code (CAPTCHA) and changing to a new password, users will be able to access the social network as usual. However, the above announcement has also made many people worried that there is a problem with their account.
Previously, Facebook had also asked its members to change their passwords several times to avoid the risk of losing their accounts (most recently in June 2013 and November 2013). This social network always recommends that users choose completely new passwords that have never been used before and avoid using the same password on many different websites and online services. However, Facebook refused to disclose how many people received the warning each time.
Security experts also advise online users to change their passwords regularly. Expert Jeremi Gosney once analyzed 130 million stolen passwords from Adobe and found that 1.9 million of them were "123456". A total of 2.75% of users chose easy-to-guess passwords such as "123456789", "password", "adobe123" and "12345678".
Facebook's password change comes just a week after US security firm Hold Security said a group of hackers known as CyberVor had collected 1.2 billion passwords and 500 million emails from 420,000 websites worldwide. "The breach is so large that if your data is somewhere on the World Wide Web, you could be one of the victims," Hold said. Security experts believe this is the largest data theft in the history of the Internet.
