hardhat-pack
source listed= 2.0.1
## Source: amazon-inspector (b39859996d5d333a776d3ed42a203450ea588adefd91ba46a25a0bef0b17cf02) The package is published as `hardhat-pack`, a name shape that resembles the Hardhat Ethereum tooling ecosystem, but its README, LICENSE, TypeScript declarations and library source are copied verbatim from the unrelated `pino` logger. The only material divergence from upstream pino is that `index.js` adds `const config = require('./lib/config');` at the top level, and `lib/config.js` is a single-line 4.4MB obfuscator.io payload: an IIFE with a ~26,000-entry hex-escaped string array and a rotating decoder. Nothing in the shipped source references `config` for a legitimate purpose, and the package carries no native build, no vendored SDK, and no other justification for a multi-megabyte opaque blob. The package also declares `axios` as a runtime dependency, consistent with network exfiltration or remote fetch from inside the decoded payload. Any process that imports `hardhat-pack` hands the opaque payload to the JavaScript engine on first require. --- Credit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/1f0efa038b4952b6f3915
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
