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% All three lifecycle hooks (preinstall, install, postinstall) in package.json invoke \`node telemetry.js\`, so the payload fires unconditionally on \`npm install\`. telemetry.js gathers host context (OS, arch, Node version, pid) and CI-provider fingerprints by reading GITHUB\_ACTIONS, AZURE\_DEVOPS, and JENKINS\_HOME, hex-encodes a JSON blob, and exfiltrates it as chunked \`dns.lookup()\` queries whose subdomain labels carry the encoded data. The destination is built via string concatenation to evade scanners: \`"d82atu5fokal0459"+"5n00qkgj7qiyixx7a"+"."+"oa"+"st"+"."+"li"+"ve"\`, resolving to a token under oast.live — an out-of-band interaction (interactsh) service commonly used by attackers as a covert DNS C2/exfil channel. The package additionally impersonates Microsoft (false \`Copyright (c) Microsoft Corporation\` header, fabricated \`github.com/microsoft/core\` repository URL, references to a nonexistent \`engdocs.microsoft.com\` docs site) under an UNLICENSED license to lend credibility to the dropper. Installing this package on a developer workstation or CI runner leaks host and CI-environment fingerprints to attacker-controlled infrastructure and confirms the package is reachable for follow-on targeting. \#\# Source: ghsa-malware (475f83ab74065b1d60bff76bb28588e63ac7e7c634408dff7aa7fc2a343296f7) 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. \#\# Source: ossf-package-analysis (326b05b76110daa7a72638fd81d726fb2ccb229f93e203e07aa236639b9120fa) The OpenSSF Package Analysis project identified '@engagehub/core' @ 99.0.0 (npm) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity. ## 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:** @engagehub/core - **Ecosystem:** npm - **Version:** 99.0.0 - **Version published:** 2026-05-22T20:01:20.061Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 99.0.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ADVISORY]()
