Cryptojacking refers to attackers' unauthorized use of someone's computer to mine cryptocurrency for financial gain, where victims unknowingly contribute computational resources. Attackers exploit victims' CPU and GPU capabilities through malware delivered via phishing emails, infected websites, or compromised software downloads. Organized cybercriminal groups often orchestrate cryptojacking schemes, leveraging technical expertise and system vulnerabilities to deploy sophisticated malware.
How Cryptojacking Works
Cryptojacking involves malware designed to hijack a victim’s computing resources for cryptocurrency mining. The malware typically spreads through:
- Malicious email attachments
- Infected websites
- Compromised software downloads
Once installed, the malware runs silently in the background, utilizing the victim’s CPU and GPU power to mine cryptocurrency. This process consumes significant resources, slowing down the computer and potentially causing overheating. Mined cryptocurrency is then sent to the attacker’s digital wallet.
