Cryptojacking
Cryptojacking is the unauthorized use of someone else's computing resources to mine cryptocurrency. Attackers typically achieve this by tricking users into downloading malware or by exploiting website vulnerabilities, leading to increased electricity costs and performance degradation for the victim.

How Does Cryptojacking Work?
Cryptojacking operates in two main ways: malware-based and browser-based. Malware-based cryptojacking involves installing malicious software on a victim’s device that runs mining scripts in the background. Browser-based cryptojacking uses JavaScript code embedded in websites or online ads, which executes when a user visits the site, consuming their CPU power.
Comparative Analysis
Cryptojacking is distinct from legitimate cryptocurrency mining, which is done with the owner’s consent and often on dedicated hardware. Unlike ransomware, which demands payment, cryptojacking aims for stealthy, continuous resource exploitation. It’s a form of cybercrime that directly impacts a victim’s operational costs and system performance.
Real-World Industry Applications
While not an ‘application’ in the traditional sense, cryptojacking impacts businesses and individuals by hijacking their processing power. It can affect servers, personal computers, and even mobile devices. The primary ‘application’ is the illicit mining of cryptocurrencies like Monero, which is well-suited for CPU mining.
Future Outlook & Challenges
As cryptocurrency mining becomes more sophisticated and profitable, cryptojacking remains a persistent threat. Challenges include developing effective detection methods for both malware and browser-based scripts, educating users about the risks, and browser vendors implementing stronger defenses against malicious scripts. The rise of cloud computing also presents new attack vectors.
