Description
The hardhat-test-log npm package impersonates legitimate Hardhat gas reporter packages to deliver malicious code. It contains dead code that always triggers a hidden function spawning a detached child process, which fetches and executes attacker-controlled code from a public paste service. This results in remote code execution on developer or CI machines using the package. Versions 1.1.0 and 1.1.2 are affected. No official patch or remediation is currently documented.
