Any machine that resolves @demica/core@99.99.99 from the public registry — typically because an internal build accidentally pulled the public squat instead of the private @demica/core — silently announces itself to the operator of 157.230.17.236, disclosing the installer's egress IP, the presence of the @demica internal namespace in the build, and confirmation that the dependency-confusion attack succeeded. The beacon body is metadata-only (no env/filesystem/credential reads), but the install-time outbound HTTP to a hardcoded attacker-controlled bare IP, fired without consent on default install, is the canonical dependency-confusion exploitation primitive and gives the publisher exactly the reconnaissance signal needed to identify and escalate against vulnerable internal build pipelines. \#\# Source: ghsa-malware (868fdb41b8eb3bf77a844a3c919d8b985ba1c93a1c56e131f970f549d6e516ee) 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:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @demica/core - **Ecosystem:** npm - **Version:** 99.99.100 - **License:** UNLICENSED - **Version published:** 2026-06-08T19:16:28.753Z - **Package first seen:** 2026-08-13T15:48:39.643Z - **Package last seen:** 2026-08-13T23:45:11.380Z - **Known versions:** 3 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Authorized benign dependency-confusion canary for FIS Bugcrowd testing. - **Maintainers:** nirox - **Artifact files:** 4 - **Artifact unpacked size:** 1,896 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [REPORT]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
