Computer users may want to double check if something – or someone – is latching onto their devices, as experts recently raised the alarm on cryptojacking. Tech experts defined cryptojacking as an online activity that aims to exploit an untapped resource to develop an alternative revenue stream for games or media sites and simultaneously reduce the need to advertise.
“We’ve seen malicious websites use embedded scripting to deliver malware, force ads, and force browsing to specific websites. We’ve also seen malware that focuses on either stealing cryptocurrency wallets or mining in the background. Combine the two together and you have a match made in hell,” said Karl Sigler, threat intelligence research manager at SpiderLabs.
Tech experts also raised concerns on the increasing number of cryptojacking activities over the past few months. Likewise, the experts noted that the activities have already taken a toll on the users’ devices and electricity bill by getting all the CPU cycles required to carry out cryptojacking.
“There was a steady increase in CoinHive usage through late November and early December, presumably driven by the surge in cryptocurrency valuations. It’s hard to guess the motivation of an unknown website operator, but based on an analysis of our detection data for the month of November, most coinmining sites were doing it on purpose, and a significant majority were taking all the CPU they could get,” Paul Ducklin, senior technologist at the security firm Sophos, said in a Wired.com entry.
