Cryptojacking, the covert use of an individual’s or organization’s computing power for cryptocurrency mining, poses a significant threat. This unauthorized practice often involves malware installed through phishing or code snippets inserted into ads or web pages. Cybercriminals exploit victims’ resources to mine cryptocurrency without the associated costs, leading to compromised system performance and increased electricity bills. The process of cryptocurrency mining, integral to blockchain transactions, is explained, highlighting the decentralized nature of blockchains. Various cryptojacking methods, such as malware, code injection, and cloud-based attacks, are detailed. Examples like Coinhive, WannaMine v4.0, BadShell, Facexworm, and Black-T underscore the diversity of these threats. The consequences for individuals include slow computers, while enterprises face reduced productivity and increased operational costs. Protecting against cryptojacking involves challenges for security teams, including identifying events, stopping breaches, and learning from attacks. Strong security hygiene, employee education, and deploying advanced endpoint protection are crucial for mitigating this growing menace.
