Google Bans All Cryptomining Extensions From the Chrome Store

In theory, cryptojacking can be used for legitimate purposes, like raising revenue for a publishing platform or collecting funds for charitable causes. But in practice, the technology has largely been implemented maliciously, or at least secretly, consuming processing resources on victim devices and potentially interfering with and damaging these targets. Bad actors can use locally installed malware to steal a victim device’s computing power, embed miners directly into websites to target casual web users without needing to install anything, or hide miners in the most innocuous applets and tools.

Cryptojacking has even found its way into critical infrastructure systems.
