How It Works
Attackers distribute malicious software through phishing emails, infected websites, or malicious downloads.
The malware installs cryptocurrency mining software that runs in the background.
The mining software uses the victim's CPU and GPU resources to solve complex mathematical problems.
Generated cryptocurrency is sent directly to the attacker's digital wallet.
The mining process continues silently, often going undetected for extended periods.
