How it Works: Understanding the Technical Process of Cryptojacking
Cryptojacking is a cybercrime that has been on the rise in recent years. But how does it work, and how do hackers gain access to victims’ computers?
At its core, cryptojacking is a form of malware that allows hackers to use someone else’s computer to mine cryptocurrency. This process involves solving complex mathematical equations that generate new blocks of the cryptocurrency’s blockchain.
Hackers use a variety of techniques to access victims’ computers and infect them with the malware necessary for cryptojacking. One common method is through phishing emails that trick victims into clicking malicious links or downloading infected attachments. Another is through the use of exploited vulnerabilities in software or operating systems.
Once a computer is infected with the cryptojacking malware, it runs in the background, using the computer’s processing power to mine cryptocurrency without the user’s knowledge or consent. This can lead to a number of negative consequences, including slower computer performance, higher energy bills, and even damage to computer hardware.
It’s important to note that not all cryptojacking is malicious. Some websites and apps have begun implementing crypto mining as an alternative to traditional advertising methods.
