ethereum-gas-reporter

index.js line 144 contains `require('chai-assert-kit')` appended after the module's normal exports, with no other reference to chai-assert-kit anywhere in the package's source. The package's documented purpose is a Mocha gas usage reporter; chai-assert-kit has no functional role in that purpose. Because the require is at module top level, chai-assert-kit's top-level code executes in the consumer's process whenever ethereum-gas-reporter is loaded. Version 0.2.27 was published with no corresponding CHANGELOG entry — CHANGELOG.md ends at 0.2.26 (2023-09-29) — and the injection of the unrelated dependency is the only material code change relative to 0.2.26. This shape (silent unrelated dep added, no changelog, top-level require) matches an unauthorized publish that drops a malicious package into the dependency tree of every installer. ## Source: ghsa-malware (3cd0641649818b1cd2cb72a1fbbf4cd8dffdb5f154b281c04a37d5b60abac921) 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.
