This report shows the evidence for dolyame-ui-container@35.3.7, 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 binary download-and-execute chain unrelated to the claimed UI toolkit. Absence of an npm lifecycle hook does not mitigate execution on ordinary package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Unconsented remote code execution under the importing process user.
Mechanism
Obfuscated HTTPS/DNS payload download followed by detached native execution.
Attack narrative
The public entrypoint catches and suppresses loading errors from _compat.js, whose top-level main() runs on every import. It selects an OS payload path, fetches an opaque binary from obfuscated Workers hosts or DNS TXT records, writes it to a temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js at module load
- _compat.js downloads platform binaries over HTTPS
- DNS TXT fallback reconstructs a binary payload
- Downloaded binary is written, chmodded, and detached-spawned
- Network hosts are obfuscated by string concatenation
- Errors and output are silently suppressed
Evidence against
- package.json has no lifecycle scripts
- lib/telemetry.js is not referenced by the public entrypoint
