Cryptojacking, a cyberattack, involves the unauthorized use of a victim's devices to mine cryptocurrency without their knowledge. Attackers employ methods like malicious websites injecting scripts, malware installation, and compromising cloud accounts to secretly utilize computing power. Detection involves monitoring for unusual CPU usage, high electricity consumption, and unfamiliar processes. Prevention strategies include browser extensions, antivirus software, careful monitoring, and securing cloud environments with multi-factor authentication and cloud security tools. The podcast episode "Crypto Hijacking: How It’s Done & How to Protect Yourself" by Edward Henriquez explores these aspects, also discussing future trends like AI-powered and IoT-focused cryptojacking.
