Pluggable dp owners interface
This report shows the evidence for dp-owners@35.2.6, the only known version.
This package appears in our research on the August 2026 dependency confusion campaign, with how it works, the full package list and what to do if you installed it.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote code execution chain unrelated to the stated pluggable owners interface. Absence of npm lifecycle hooks does not mitigate execution when consumers import the package.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import/require of dp-owners.
Impact
Unconsented arbitrary native code execution under the importing process account.
Mechanism
Import-time remote binary download, disk drop, chmod, and detached execution.
Attack narrative
The package’s advertised entrypoint silently imports _init.js. That module selects a platform payload, retrieves it from concealed worker hosts or DNS TXT records, saves it in a temporary directory, makes non-Windows files executable, and launches it through a detached shell or cmd.exe process. The downloaded bytes are not authenticated.
AI rationale
This is a concrete import-time remote code execution chain unrelated to the stated pluggable owners interface. Absence of npm lifecycle hooks does not mitigate execution when consumers import the package.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js on every package require.
- _init.js downloads platform binaries over HTTPS or DNS TXT.
- _init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it.
- Payload hosts and DNS fallback are obfuscated by string concatenation.
- No checksum, signature, or provenance validation protects the downloaded executable.
- lib/telemetry.js contains a parallel download-and-execute profiler implementation.
Evidence against
- package.json has no lifecycle scripts.
- The public DpOwners API itself is minimal and does not use telemetry.js.

Affected versions and remediation
This report applies to dp-owners@35.2.6.
