Hackers steal tens of thousands of users via Facebook quizzes

The hackers used the obtained data to target Facebook's users with a malicious request to install a browser extension.

Two Ukrainian hackers known as Gleb Sulchevsky and Andrey Gorbachov are facing trial for injecting advertisements into Facebook News Feed with quizzes.

Facebook's inability to secure user data is being highlighted once again, this time after it was determined that several Ukrainian hackers managed to distribute online quizzes which provided them with access to user data.

From what the company wrote, apart from compromising their details on Facebook, the users also compromised their web browsers.

The Verge reported that the news follows Facebook's lawsuit against 4 Chinese companies selling fake accounts and user engagement.

Facebook is also said to be seeking other financial relief for its investigation into the defendants and restitution of any funds that the two received through the scheme.

She had been on trial alongside a Vietnamese woman, Doan Thi Huong, who was left distraught as she was not freed at the same time. Huong's lawyers have now demanded that the Malaysian attorney general should drop the charges against her too and set her free.

Sluchevsky and Gorbachov are alleged to have used aliases to operate at least four apps - including "Supertest", "FQuiz", "Megatest", and "Pechenka" - and are both affiliated with a company called the Web Sun Group, which offered web development and other technical consulting services.

Facebook notes that it publicly announced the compromise around October 31st, which roughly matches the date of a BBC report revealing the private message breach, quoting Facebook blaming malicious browser extensions. This amount according to the civil complaint was what Facebook spent in removing the malicious plugins from its website a year ago.

The hackers were uncovered after they claimed to have access to 120 million Facebook accounts.

Whether Facebook can expect any success from the suit is up in the air, given it can't compel Gorbachov or Sluchevsky to come to the U.S. to face trial.

The scheme seemingly wouldn't have worked, however, if Facebook hadn't approved the hackers as developers who could use its Facebook Login feature. Last week, Facebook CEO Mark Zuckerberg posted an essay about privacy and said he wants to focus on encrypted messaging on Messenger, Instagram, and WhatsApp.

"Sometimes, those advertisements could be more valuable", Patterson said, "because they're hyper-targeted toward specific groups of people versus a broadcast audience". The defendant may not face serious consequences, but it will give Facebook the leverage to defend itself.
