The techniques used to do this resemble those used in phishing attacks. The first is to trick a user into loading crypto mining software onto their computer, as with the recent BadShell attack – a “file-less” malware that did not require a download.
There are essentially two methods of implementing a cryptojacking attack, and both are quite similar to other forms of attack. With ransomware, criminals are reliant on users paying a ransom, whereas cryptojacking software will run silently in the background, slowly generating income. It relies on attack vectors that have long been used to deliver ransomware, or to build botnets, which all but guarantees a successful infection will generate revenue for an attacker. The rise in cryptojacking is being driven by how easy it is to implement. Indeed, some cryptojacking mechanisms make explicit use of botnets.
This rapid growth is due partly to the fact that cryptojacking relies on techniques developed to facilitate a much older form of attack: botnets. There is no doubt, however, that the practice is widespread. It’s very difficult to assess the scale of cryptojacking, not least because many of the scripts used to hijack victims’ computers are based on legitimate crypto mining software. For most users, the only indication they’ve been cryptojacked is slightly slower performance, which is why these attacks are so hard to detect.

Whichever method is used, crypto mining code then runs in the background of a victim’s computer and generates profits for an attacker. These attacks often work by getting a victim to click a malicious link in an email that then loads crypto mining code onto their computer - or by infecting an online ad with JavaScript code that executes through a browser. But there’s been a rise in the practice during recent years.Ĭryptojacking works in a fairly simple way, but that doesn’t mean it’s easy to detect or defend against. If you’ve never heard of it before, that’s likely because - up until recently -cryptojacking was a fairly niche concern.
