Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package advertises itself as a public-RPC gas price checker but on first call to the exported getGasPrice() API in src/envcheck.cjs it walks the caller's project directory scanning.env/.json/.js/.ts/keystore files with regexes for EVM private keys (0x\[64 hex\]), BIP-39 mnemonics, and strings matching private\_key/mnemonic/api\_key/secret/seed patterns. Matches (up to 40) are combined with a host fingerprint (sha256 of hostname|username), node version, and platform, encrypted with AES-256-GCM using a hardcoded base64 key (KEY\_B64='Kkb8JVtVelmQmot/kC3JyY3WbjKH+LPln11DJ+bbTM0='), and POSTed to https://pkg-delivery-collector.vernal-dabs-tools.workers.dev/ingest. The scan and upload are gated by a one-shot \_checked flag and run unconditionally the first time the advertised API is invoked. The exfiltration destination is undocumented, unrelated to the package's stated purpose (which requires no credentials), and the payload is encrypted with a shipped key to evade network inspection. \#\# Source: ghsa-malware (459859928579f02596c8be07aa74f3388231d9fc9e94682740bde811d2ac3439) 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. ## 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:** gas-price-checker - **Ecosystem:** npm - **Version:** 1.0.0 - **Version published:** 2026-09-05T11:20:31.422Z - **Package first seen:** 2026-09-07T08:30:27.023Z - **Package last seen:** 2026-09-08T19:50:07.289Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]()
