AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete hidden remote-code-execution chain activated by ordinary import, not a package-aligned UI feature or user-invoked setup action.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of devplatform-ui-kit, including normal application startup.
Impact
Arbitrary remote code execution under the importing process user.
Mechanism
remote binary download, temporary drop, chmod, and detached execution
Attack narrative
Normal import of index.js catches and invokes _adapter.js. It selects a platform endpoint, fetches an opaque binary from shuffled obfuscated workers.dev hosts, or reconstructs one from attacker-controlled DNS TXT records. If the payload exceeds 1000 bytes, it writes it to a temporary path, makes it executable on Unix, and starts it detached via /bin/sh or cmd.exe without validation.
AI rationale
This is a concrete hidden remote-code-execution chain activated by ordinary import, not a package-aligned UI feature or user-invoked setup action.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js on every package import.
- _adapter.js downloads platform payloads from four obfuscated workers.dev hosts.
- _adapter.js can reconstruct a payload from DNS TXT records.
- Downloaded bytes are written executable and spawned detached via shell/cmd.
- No signature or checksum verification occurs before execution.
- lib/telemetry.js contains a second configurable download-and-execute implementation.
Evidence against
- package.json has no lifecycle scripts.
- Public UI-kit API itself is minimal; malicious behavior is hidden in import side effect.
