A virus that turns victims’ computers into a cryptocurrency miner without their knowledge is spreading across Facebook Messenger, security experts have warned.
The malware, named “Digmine”, affects desktop versions of the app when running on a Google Chrome browser, according to researchers at Trend Micro.
“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,” they wrote in a blogpost.
Mining a Bitcoin eats up a lot of power and so it has become lucrative for criminal gangs to infect computers en masse to do the job, earning them cryptocurrency including Bitcoin in return.
With a finite supply of 21 million Bitcoins, a handful of opportunistic individuals and organizations are making use of powerful computers to hoard as much of the supply as possible.
