How to tell if your account has been hacked

How to tell if your account has been hacked

Hundreds of Islanders are thought to have been affected by the hack, which exploited a security flaw in one of Facebook's privacy features.

The severity of this bug was that the attackers could continue using your Facebook account pretending to be the real account holders, as they had your access token to provide them actual authentication to your account.

The social media company announced last week that about 50 million user accounts worldwide had been accessed by hackers, with another 40 million left vulnerable during the attack.

The company has also reset the access tokens of the 50 million accounts that were known to have been breached, as well as 40 million accounts that have been subject to a "View As" look-up in the a year ago, as a precaution. A spokeswoman for the company said it would respond to follow-up questions from Ireland's DPC and keep regulators up to date with its investigations. There is also a possibility that the hack could have affected third-party applications, for instance, Tinder and Swiggy, that you might have logged into via Facebook. According to the company hackers exploited the "View As" feature on the service and steps are being taken to fix the security problem.

Facebook chief executive Mark Zuckerberg said engineers discovered the breach on Tuesday, and patched it on Thursday night.

Europe's General Data Protection Regulation law, which went into effect in May, levies heavy fines-$23 million or 4% of world-wide revenue the previous year, whichever is higher-if it determines a company didn't do enough to protect its customers' data.


Cambridge Analytica, which denies the accusations, has since filed for voluntary bankruptcy in the United States and Britain.

But because of the way the hack worked, it also gave attackers the same level of access to any accounts you use Facebook to log in with.

It's not clear whether this has actually occurred - when asked, a Facebook exec said only that the company was early in its investigation - but the possibility may force the other companies to undertake their own investigations into the issue.

Beyond the CA scandal, Facebook estimates the data of almost all its users may have, at some time, been retrieved without their knowledge.

"We will be making enquiries with Facebook and our overseas counterparts to establish the scale of the breach and if any United Kingdom citizens have been affected".

The sites have acknowledged finding on their platforms messages, accounts and pages associated with the Internet Research Agency, a Saint Petersburg operation that is alleged to be a "troll farm" connected to the Russian government. That political consulting firm told Facebook it had deleted the information, but it hadn't.

"So, if Facebook is found not to have taken sufficiently robust measures [to prevent the vulnerability], it may be held to have infringed GDPR, even if its response since has been exemplary". A breakdown of how Facebook spotted the breach is available in this ZDNet article, here.
