Hackers appear to have private messages of 81,000 Facebook compromised accounts reportedly stolen through rouge browser extension that monitors the conversations and send’s the data back to hackers.
Hackers offering the data for less than 10 cents (8p) per account, most of the compromised user accounts based in Ukraine and Russia and few accounts from UK, US, Brazil and elsewhere.
“We have contacted browser-makers to ensure that known malicious extensions are no longer available to download in their stores,” said Facebook executive Guy Rosen.
Digital Shadow examined the compromised data that the sample data posted contains the private messages of 81,000 Facebook users.
“Data from a further 176,000 accounts was also made available, although some of the information including the email addresses and phone numbers, could have been scraped from members who had not hidden it,” reads BBC blog post.
BBC Russian service emailed to the advertised email address alongside the hacked details and posing as buyer interest.
The advertiser of the data confirmed the data was not associated with Cambridge Analytica scandal or the subsequent security breach revealed in September.
“We have also contacted law enforcement and have worked with local authorities to remove the website that displayed information from Facebook accounts,” Rosen said.
Last October Facebook said that hackers accessed 29 million Facebook users data by the recent data breach and stolen users personal details such as Email and phone number and other data what compromised user had in their accounts.
Following to that hackers advertised stolen Facebook credentials between $3 and $12 and it can be purchased only through the bitcoin and bitcoin cash.
