What Is Cryptojacking?
Cryptojacking is a form of cybercrime where hackers secretly use a victim’s computer or device to mine cryptocurrency without their knowledge or consent. The attacker typically installs malware on the victim’s device, which uses the device’s processing power to mine digital currency, such as Bitcoin or Monero. This unauthorized use of resources can slow down devices and cause overheating, as the system is working harder than intended.
How Cryptojacking Works
Cryptojackers often spread their malicious software through phishing emails, malicious websites, or infected ads. Once installed, the mining malware runs in the background, using the device’s CPU or GPU to mine cryptocurrency. The hacker receives the mined currency, while the victim is left with a slower, overworked system that may suffer from decreased performance or potential damage.
Why Cryptojacking Matters
Cryptojacking is a growing threat to both individuals and organizations because it takes advantage of their computing resources without consent. Although cryptojacking does not typically result in the theft of personal information, it can lead to significant performance issues, higher electricity costs, and hardware damage. For businesses, it can also lead to decreased productivity and network security risks.
The Simple Takeaway
Cryptojacking is the unauthorized use of someone’s computer or device to mine cryptocurrency. It can slow down systems, cause damage, and steal computing resources without the victim’s knowledge.
