As cryptocurrency values continue to climb, a dangerous cyber threat known as cryptojacking has seen explosive growth. This malicious practice involves hackers hijacking victims’ computing resources to mine cryptocurrencies without their knowledge or consent.
What Is Cryptojacking?
Cryptojacking occurs when cybercriminals install malware—often via phishing scams or compromised websites—to secretly harness the processing power of devices (computers, smartphones, or servers). The hijacked resources are then used to mine cryptocurrencies, which can:
– Slow down device performance.
– Increase electricity costs due to mining’s high energy demands.

Key Statistics: A Global Epidemic
According to SonicWall’s Annual Cyber Threat Report:
– 2023 saw 1 billion cryptojacking attacks, a 659% increase from 2022.
– Europe experienced the sharpest rise (1,046%), followed by North America (596%).
| Region | Year-over-Year Increase |
|---|---|
| Europe | 1,046% |
| North America | 596% |
Why the Sudden Surge?
Ari Redbord, Global Policy Lead at TRM Labs, attributes this trend to:
1. Bullish crypto markets: Higher token prices make illicit mining more profitable.
2. DeFi’s growth: Over $100 billion locked in decentralized finance protocols presents a lucrative target.
Despite a 50% drop in total crypto hack losses (to $1.7 billion in 2023), attack frequency remained steady, with 160 major incidents recorded.
The Invisible Threat
Cryptojacked coins are indistinguishable from legitimately mined cryptocurrencies. As Bobby Cornwell (VP at SonicWall) notes, this makes it “nearly impossible” to track the volume generated by attackers.
FAQs
