Another problem with Facebook. Millions of users' phone numbers leaked onto the internet

A leaked database of data from one of Facebook's servers was circulating on the Internet. Among other things, it contained users' phone numbers along with their profile identifier.

Facebook seems to he still could not avoid security scandals. This time, a database with user data from one of the servers was leaked. North TechCrunch it also informs that it was a poorly secured server.

The entire database contains around 133 million phone numbers of users from the US, 18 million phone numbers of users from Great Britain and 50 million from Vietnam. Other countries can be found among them, but in smaller numbers.

The database contained a summary of data, in particular the phone number and unique identifier of the user's profile. However, it was not an exception that the country, gender, city or birthday was also filled in.

Facebook reportedly blocked and secured phone numbers over a year ago. The official statement on the whole leak is that "this is already a year old data". According to company representatives, there was no major risk.

Year old numbers still working and SIM hacking

However, TechCrunch editors proved the opposite. They managed to match the phone number to the real link to the Facebook profile for several records. Then they simply verified the phone number by trying to reset the password, which always shows a few numbers. The records matched.

The whole situation is becoming more serious because the so-called SIM hacking has been on the rise lately. Attackers are able to request activation of a phone number for a new SIM from the operator, which they will then use to capture two-factor authentication codes for services such as banking, Apple ID, Google and others.

Of course, SIM hacking is not that simple and requires both technological knowledge and the art of social engineering. Unfortunately, there are already organized groups that operate in this area and cause wrinkles on the foreheads of many institutions and companies.

So it can be seen that a "year-old" database of Facebook users' phone numbers can still do a lot of damage.
