Cryptojacking Attacks Skyrocket 659%, Costing Victims $53 per Dollar Mined

Cryptojacking attacks have become increasingly sophisticated and widespread, with SonicWall detecting a staggering 1.06 billion incidents in 2023, a 659% surge over the previous year.

Unlike ransomware, which demands payment immediately, cryptojacking operates silently in the background, using unauthorized computing resources to mine cryptocurrency without the device owner's knowledge or consent.

Sustained processor usage above 50% during idle periods is a reliable indicator of cryptojacking. Mining malware consumes CPU and GPU cycles to solve cryptographic puzzles, generating measurable load. Legitimate background processes rarely sustain usage above 20%.

Cryptojacking can cause significant hardware degradation and inflated electricity bills. Sysdig research shows victims pay $53 in cloud compute costs for every single dollar of cryptocurrency that the attacker successfully mines through compromised infrastructure.
