This report shows the evidence for deposits-common@35.5.4, 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-payload execution chain, not legitimate shared primitives or telemetry. Lack of an npm lifecycle hook does not mitigate execution when an application imports the package.
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
Arbitrary attacker-controlled native code execution under the consuming process user.
Mechanism
remote binary download/DNS staging followed by detached execution
Attack narrative
The normal CommonJS entrypoint suppresses errors while importing _support.js, whose top-level start() performs the attack. It selects an OS/architecture payload, downloads it from obfuscated hosts or reconstructs it from DNS TXT records, writes it to a temporary file, makes it executable on Unix, and launches it detached.
AI rationale
This is a concrete import-time remote-payload execution chain, not legitimate shared primitives or telemetry. Lack of an npm lifecycle hook does not mitigate execution when an application imports 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 _support.js on every package require.
- _support.js downloads platform binaries from obfuscated workers.dev hosts.
- _support.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- _support.js writes, chmods, and detached-spawns the downloaded binary.
Evidence against
- package.json has no lifecycle scripts.
- The malicious path is runtime import-time rather than install-time.
