Bigops products SDK for internal consumers
This report shows the evidence for bigops-products@35.7.4, 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 concrete import-time staged remote code execution, unrelated to the package's minimal documented SDK API. The lack of lifecycle hooks does not mitigate the reachable runtime payload chain.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js require/import of the package main entrypoint.
Impact
Arbitrary native code can execute as the importing user's account.
Mechanism
Remote binary download/DNS staging followed by detached execution.
Attack narrative
The benign-looking main module silently requires _init.js. On import, it selects a platform payload URL, downloads a binary from rotated obfuscated hosts or reconstructs it through DNS TXT records, writes it under a deceptive temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. Failures are swallowed and a temporary timestamp marker reduces observable repeats.
AI rationale
This is concrete import-time staged remote code execution, unrelated to the package's minimal documented SDK API. The lack of lifecycle hooks does not mitigate the reachable runtime payload chain.

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 on every package require.
- _init.js downloads platform binaries from obfuscated workers.dev hosts.
- _init.js falls back to DNS TXT payload retrieval from *.dl.wel1.ru.
- _init.js writes payloads into /var/tmp or TEMP, chmods Unix files, then detaches shell execution.
- _init.js suppresses all errors and uses a temporary marker to limit repeat attempts.
- lib/telemetry.js contains the same download-to-temp-and-spawn primitive.
Evidence against
- package.json has no npm lifecycle scripts.
- No direct credential or project-file harvesting was found.
