Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (7992916c62a9926f06f313367b6b684674413ecac4fe8cf1e0130165ae651fc7) On require of the package, index.js loads _adapter.js, which downloads a platform-specific native binary from hardcoded destinations assembled via array-join concatenation (oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev) with a fallback that reassembles the executable from base64 chunks retrieved over DNS TXT records at c.dl.wel1.ru, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched bytes are written to /tmp or %TEMP% under disguised names (dotnet_diag_*.exe,.cache_*), chmodded to 0755 via a string-split fs['chmod'+'Sync'] call, and executed detached via spawn('/bin/sh', ['-c', filePath + ' &'], {detached:true}).unref() or a cmd equivalent on Windows. A ~24h marker file suppresses re-execution. A sibling lib/telemetry.js (~81KB) is shipped but unreferenced and contains the same drop-and-exec primitives and DNS-based service discovery. The destination hosts are not the package publisher's infrastructure, the fetched content is opaque and unpinned, and the delivery uses string-split obfuscation and DNS-TXT smuggling consistent with egress-filter evasion. ## Source: ghsa-malware (4b235cc0009513fb347569f9438573785c75129c5927eaf36fb4c685516b4409) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Impact

Successful execution of this malicious package results in arbitrary native code running on the host system with the permissions of the executing user. This can lead to system compromise, persistence, and potentially further malicious activity. The opaque and unpinned nature of the downloaded payloads means the exact impact depends on the fetched binary, which is controlled by threat actors. The use of obfuscation and DNS-based payload retrieval complicates detection and blocking.

Defensive guidance

Users should immediately cease using version 35.5.5 of dolyame-boxy-atom-bnpl-card and remove it from their environments. Avoid installing or requiring this package from untrusted sources. Employ network egress filtering to block connections to the identified malicious domains and DNS TXT record queries to the specified domains. Monitor for execution of suspicious binaries in temporary directories with the described naming patterns. Check vendor advisories or trusted security sources for updates or fixes.

Summary

The npm package dolyame-boxy-atom-bnpl-card at version 35.5.5 contains embedded malicious functionality. When the package is required, its index.js loads _adapter.js, which downloads a native binary tailored to the platform from several hardcoded external domains unrelated to the publisher. The download employs obfuscation via string concatenation and fallback retrieval of base64-encoded chunks over DNS TXT records from multiple suspicious domains. The binary is saved to temporary directories under disguised filenames, permissions are set to executable, and it is launched detached from the main process. A marker file prevents repeated execution within 24 hours. Additionally, an unreferenced telemetry.js file contains similar drop-and-execute and DNS-based service discovery code. The delivery and execution methods indicate attempts to evade egress filtering and detection.
