Blockchain News Monero Mining Botnet Infests Facebook Messenger as Mining Craze A s previously covered by Core Media, The Pirate Bay’s Monero mining botnet experiment, in which the torrent index started using JavaScript code to mine Monero using visitor’s CPUs, saw a Monero mining craze begin, using that same code. Its latest infected victim was oil pipeline giant Transneft. According to cybersecurity firm TrendMicro, the Monero mining craze has now reached Facebook users. Security experts report a cryptocurrency mining bot is spreading via Facebook Messenger, in the Google Chrome browser for desktop. Dubbed Digmine, it was first seen in South Korea but already spread to various countries including Venezuela, Ukraine, and Vietnam. Given how fast its spreading, it’ll likely show up in other regions soon. Digmine essentially masquerades as a link to a non-embedded video file that, in reality, 26 Core Magazine is an executable script. Once the file is clicked on, the script downloads components from a server so it can install a Chrome extension to mine Monero. Then either streams a bogus video or manipulates the person’s account to send its link to their Facebook friends – if their account is set to log in automatically. The researchers wrote: “A known modus operandi of cryptocurrency-mining botnets, and particularly for Digmine (which mines Monero), is to stay in the victim’s system for as long as possible. It also wants to infect as many machines as possible, as this translates to an increased hashrate and potentially more cybercriminal income.” Interestingly, Digmine only works on Chrome, and on desktops. If the victim clicks on the link using another browser or a mobile device, it won’t work as intended.
