Dear Tecnogalaxy readers, in these days we are reading on various social networks and on articles of the “computer security” sector, that personal data of 533 million Facebook and Linkedin users have been leaked and made available for download in the dark Web.

The leak of information has been received by security researcher Alon Gal, and later the leak has been confirmed by Business Insider, which specified that among the data, in addition to email addresses, have been spread also the phone numbers connected to the compromised accounts, including even full names and geographical locations….crazy!!!

The data breach affected the personal information of 533 million users from 106 nations. “Italy is among the most affected nations,” it was posted for free on a low-level hacking forum by an unknown user.

This data is a couple of years old because it was already leaked for a fee on a Telegram bot last January. According to a Facebook spokesperson, this data had been deleted due to a security vulnerability that was fixed in 2019.

If we think about the size of that database containing private information, (phone numbers of many Facebook users), it could be exploited by cybercriminals who take advantage of this data to perform social engineering attacks.

Have I Been Pwned

To find out if your data has unfortunately ended up in the blacklist, we can use a free service Have I Been Pwned accessible at the following link:

The site collects in its database all the biggest leaks, this thing allows users to make a verification by checking if their email address or mobile number is involved in the fraudulent spread.

Just enter the email or mobile number in the field and press the button:

If the result is “Good news – no pwnage found!” you can rest assured.

If the message will be “Oh no – pwned!” it means that your email address has appeared in some violation, take immediate action by changing the password of your email account.

Facebook hacked: find out if you're safe

As always use complex passwords, do not use the same password on different social networks, sites etc….change your password often.

As always, make good use of it by testing it on your device/computer, testing it on devices/computers that are not yours is illegal.
