OpenSSF/OSV advisory MAL-2026-4501 confirms this npm version as malicious. The package presents itself as a clone of juliangruber/balanced-match (stolen author identity 'Julian Gruber \', verbatim README, identical API renamed btdSmart, placeholder homepage 'github.com/your-org/btd-smart'). Appended to the legitimate code in index.js is an obfuscated block that runs unconditionally when the module is required... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to btd-smart@1.0.3. The same advisory and Firewall decision cover these 2 recorded versions: 1.0.2, 1.0.3. - Avoid installing btd-smart@1.0.3. 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% The package presents itself as a clone of juliangruber/balanced-match (stolen author identity 'Julian Gruber \', verbatim README, identical API renamed btdSmart, placeholder homepage 'github.com/your-org/btd-smart'). Appended to the legitimate code in index.js is an obfuscated block that runs unconditionally when the module is required. A custom string-shuffle decoder reconstructs the identifier 'constructor' (and other strings) without any literal occurrences in the file, retrieves the Function constructor from a string prototype, builds a function from a decoded source body, and invokes it. Before invocation, the code stashes \`require\` and \`module\` onto \`global\` under decoder-produced keys so the Function-built code — which otherwise has no closure scope — gains filesystem, network, and process capabilities. The payload body is opaque (deterministic numerical shuffle with 0x7F-based escape tricks across two nested decoders), executes on every \`require('btd-smart')\`, and the legitimate balanced-match code above it has no obfuscation, confirming the appended block is purposefully hidden. Combined signals — typosquat with stolen identity, custom obfuscator, dynamic Function eval of a decoded blob at module load, deliberate global-smuggling of require/module — match the documented active-attack shape; no legitimate brace-matching utility needs any of these mechanisms. \#\# Source: ghsa-malware (8edce8a8e04e183f3bd29cb37d2f3916debf1ebd05c0cbe50fb5f1920f2fa932) 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:** btd-smart - **Ecosystem:** npm - **Version:** 1.0.3 - **Version published:** 2026-05-15T10:01:11.003Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 1.0.3 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
