Commentary: Latest Facebook data breach reveals troubling implications for users

Over the long weekend, reports emerged of an alleged data breach, impacting half a billion Facebook users from 106 countries.

And while this figure is ทดลองเล่นslotxo staggering, there’s more to the story than 533 million sets of data. This breach once again highlights how many of the systems we use aren’t designed to adequately protect our information from cyber criminals.

Nor is it always straightforward to figure out whether your data have been compromised in a breach or not.


What happened?
More than 500 million Facebook users’ details were published online on an underground website used by cyber criminals.

It quickly became clear this was not a new data breach, but an older one which had come back to haunt Facebook and the millions of users whose data are now available to purchase online.

The data breach is believed to relate to a vulnerability which Facebook reportedly fixed in August 2019. While the exact source of the data can’t be verified, it was likely acquired through the misuse of legitimate functions in the Facebook systems.

Such misuses can occur when a seemingly innocent feature of a website is used for an unexpected purpose by attackers, as was the case with a PayID attack in 2019.

In the case of Facebook, criminals can mine Facebook’s systems for users’ personal information by using techniques which automate the process of harvesting data.


WERE YOU TARGETED?
There’s no easy way to determine if your details were breached in the recent leak. If the website concerned is acting in your best interest, you should at least receive a notification. But this isn’t guaranteed.

Even a tech-savvy user would be limited to hunting for the leaked data themselves on underground websites.

The data being sold online contain plenty of key information. According to haveibeenpwned.com, most of the records include names and genders, with many also including dates of birth, location, relationship status and employer.

Although, it has been reported only a small proportion of the stolen data contained a valid email address (about 2.5 million records).
