JavaScript Malware

Definition ∞ JavaScript malware is malicious code written in the JavaScript programming language, designed to compromise user systems or digital assets. This type of malware often operates through compromised websites or browser extensions, aiming to steal private keys, redirect transactions, or inject fraudulent scripts into user interfaces. Its prevalence poses a significant risk to users interacting with web-based crypto applications.
Context ∞ Reports on JavaScript malware are pertinent when discussing the security of cryptocurrency exchanges, decentralized applications (dApps), or any web interface that handles digital assets. Awareness of these threats is crucial for users to adopt secure browsing habits and employ protective measures against sophisticated phishing and credential theft schemes.
