Summary
Malicious code in dolyame-ui-popup (npm)
Details
On require('dolyame-ui-popup'), index.js loads _helpers.js which immediately fetches a platform-specific binary from string-split Cloudflare Workers mirrors (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT fallback across sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes it to a hidden path under /tmp or the Windows temp directory (.cache_<hex>, dotnet_diag_<hex>.exe), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start. No hash or signature verification is performed and the destinations are assembled from split string fragments (['sdk.dl.w','el1.ru'].join(''); require('child_'+'process'); fs['chmod'+'Sync']) to defeat static analysis. lib/telemetry.js contains a second, structurally identical dropper labeled as an analytics SDK, using base64-over-DNS chunk assembly. The package advertises UI popup components but ships no UI code — the tarball's only effect on installation is fetching and executing an unverified remote binary under an attacker-controlled domain.
References
Independent LPM AI assessment
SuspiciousIndependent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.
The package contains an import-reachable remote binary loader, but a source-level syntax error stops it from executing in this version. This meets the inert payload carrier threshold for a warning, not a publish block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
User code imports dolyame-ui-popup.
Impact
If the parse error is corrected, arbitrary remote native code would run under the importing process user.
Mechanism
Attempted remote binary download, temporary-file drop, chmod, and detached execution.
AI rationale
The package contains an import-reachable remote binary loader, but a source-level syntax error stops it from executing in this version. This meets the inert payload carrier threshold for a warning, not a publish block.

Independent scan evidence
public snapshotAI called this Suspicious at 98.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for AI warning decision
- index.js imports _helpers.js at package import time.
- _helpers.js downloads platform binaries, including from oob-worker.cf102-baf.workers.dev.
- _helpers.js can DNS-fetch a base64 payload from *.dl.wel1.ru, write it to /var/tmp or Windows Temp, chmod it, and spawn it.
- The payload is hidden behind a telemetry-themed marker and opt-out variables.
Evidence against
- package.json has no lifecycle scripts.
- _helpers.js declares const _ppid twice in init(), a syntax error; index.js swallows the failed require, so this payload cannot execute as shipped.
- lib/telemetry.js is not imported by the entrypoint; its native-loader path requires caller-supplied endpoints/mirrors.
