Malicious code in hardhat-hold (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (e961a4e9f774d02e73039b143503a3fff7cad6fdbf164123d76a3d5de53c667e) The package's main entry index.js unconditionally requires./lib/config, which is a ~4MB obfuscator.io-style blob (string array of ~23,981 entries with a rotating decoder and hex-escaped literals). The readable identifiers inside that payload include execSync (child_process) and axios (HTTP client) — the local-execution and outbound-network primitives used by droppers and exfiltration stagers — and the payload runs at import time via a top-level IIFE. The wrapper index.js copies the pino logger API surface but never uses the config export; its only effect is to force the obfuscated blob to load on require(). The package name hardhat-hold is a one-token variant of the Ethereum tooling package hardhat, while the README impersonates the pino logger (including shields.io badges that still point at pino's repository), and package.json carries an unrelated boilerplate description about vulnerability management. The combination of name/README/description mismatch with an obfuscated import-time payload carrying shell-exec + HTTP primitives is the canonical typosquat-dropper shape. ## Source: ghsa-malware (6af89091e813fad5ea479c91ae40ac8fbfc58c677be758b0faa8d0c4926cb9cd) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
