Cybercriminals are using Facebook Messenger to infect computers with malware that mines cryptocurrency.
Security researchers the Trend Micro cybersecurity firm said “Digmine” is targeting as many machines as possible, in order to earn monero – an alternative to bitcoin – for its creators
It could also help cyber criminals completely take over a Facebook account, the researchers added.
The bot was detected by cybersecurity firm Trend Micro, which says “Digimine” is designed to look like a video file.
It only works when it is spread via the desktop version of Messenger, on Google Chrome. If you open it through Messenger on another platform, such as a mobile phone, Digmine won’t function as it is supposed to.
However, it can still be considered very dangerous. As well as having the potential to let hackers take over your account, it can also slow your computer down and use your Facebook account to target your friends.
“If the user’s Facebook account is set to log in automatically, Digmine will manipulate Facebook Messenger in order to send a link to the file to the account’s friends,” the researchers said.
“The abuse of Facebook is limited to propagation for now, but it wouldn’t be implausible for attackers to hijack the Facebook account itself down the line.”
Security experts recently told The Independent that bitcoin’s rapid recent rise in value might be making unsuspecting computer users more vulnerable to hackers.
It has led to more and more machines being secretly infected with malware that is designed to help cyber criminals “mine” for cryptocurrencies.
“The increasing popularity of cryptocurrency mining is drawing attackers back to the mining botnet business,” said Trend Micro.
“And like many cybercriminal schemes, numbers are crucial — bigger victim pools equate to potentially bigger profits. The fact that they’re piggybacking on popular platforms such as social media to spread their malware is unsurprising.”
They have alerted Facebook to the malware.
The social media giant said: “We maintain a number of automated systems to help stop harmful links and files from appearing on Facebook and in Messenger. If we suspect your computer is infected with malware, we will provide you with a free anti-virus scan from our trusted partners.
