Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The npm package hardhat-lock@2.21.0 publishes itself as a logger/middleware but its identity and contents are inconsistent with that purpose: README badges, LICENSE, index.d.ts and docs/\* are copied from the unrelated pino project (maintained by pinojs), while the package name squats the Ethereum-tooling keyword 'hardhat'. index.js unconditionally executes require('./lib/config') at module load, and lib/config.js is a ~4MB obfuscator.io-style single-line file (rotated string array of 23,981 entries, hex-escaped tokens, numeric wrapper decoders mt/mw/M0..M5/K/R/s/G, control-flow flattening, and 40,131 inline decoder replacements confirmed by webcrack) whose top-level IIFE runs the moment any downstream code does require('hardhat-lock'). The combination — impersonation of an established package under a different scope-adjacent name, opaque multi-megabyte obfuscated blob with no plausible logging use, and guaranteed import-time execution — is a supply-chain payload carrier: installing and loading the package places attacker-controlled code inside the consumer's Node.js process with unrestricted access to environment variables, filesystem, and network. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** hardhat-lock - **Ecosystem:** npm - **Version:** 2.21.0 - **Version published:** 2026-09-25T11:49:11.852Z - **Package first seen:** 2026-09-28T22:50:05.310Z - **Package last seen:** 2026-09-28T22:50:05.310Z - **Known versions:** 1 - **Latest version:** 2.21.0 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
