But the damage can be severe: Cryptojacking impairs computing performance, shortens the lifespan of devices, causes irreparable hardware damage, and sends energy bills through the roof. In many instances of cryptojacking, the victims are completely unaware that their systems are being exploited. (This is what happened with the supercomputers in Europe.) Common exploits may be used to infect servers or multiple machines to gain access to much larger CPU resources for crypto mining than ordinary desktop PCs provide.
Victims are completely unaware that their computer is being used to mine cryptocurrency, because the code uses only enough system resources to remain undetected. This is known as 'drive-by crypto mining'. A cryptojacker may embed a piece of JavaScript code into a web page and perform cryptocurrency mining on machines that visit the page.After the computer is infected, the cryptojacker quietly hides in the background and mines cryptocurrency. A cryptojacker may load code directly onto a computer when a victim clicks on a malicious link.There are three common methods of cryptojacking that IT teams need to be aware of: Researchers called it one of the largest and longest-lasting cryptojacking attacks of its kind to date. And according to Threatpost, in February of 2021, a cryptocurrency mining malware called WatchDog slipped under the radar and was running on at least 476 Windows and Linux devices for more than two years. And cybercriminals know it.Ĭryptojacking - the process of illegally mining for cryptocurrencies unbeknownst to the individuals or organizations that own them, rose 28% in 2020 from the previous year, with 81.9 million attempts. And while server farms and DIY home cryptocurrency mining is definitely still happening, there are ways of making just as much (if not more) profit without investing in infrastructure. Cryptocurrency is not dead - in fact, its market size is projected to grow to more than $1billion by 2026.
