Cryptojacking is the unauthorized use of someone else’s computing resources to mine cryptocurrency. This typically occurs through malicious software that is secretly installed on a victim’s device, such as a computer or smartphone.Once infected, the device is used to solve complex mathematical problems required for mining without the owner’s knowledge. This process can significantly slow down the affected machine, increase energy consumption, and lead to higher electricity bills.Cybercriminals often distribute cryptojacking scripts through phishing emails, compromised websites, or infected software downloads. In some cases, attackers use browser-based mining scripts that run when users visit certain pages.Victims may not realize their devices are compromised, but the impact can be severe, affecting performance and security. To prevent such attacks, users should keep software updated, use reliable antivirus tools, and be cautious when clicking on unknown links or downloading files.
