Malicious code in dolyame-boxy-desktop-bnpl-picture-gallery (npm)

The binary is written under /var/tmp or %TEMP% with disguised names such as dotnet_diag_<rand>.exe or.cache_<rand>, chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. A DNS-TXT fallback channel under *.dl.wel1.ru (resolver domains also assembled from split fragments) reads a count from c.<domain> TXT and iterates <n>.<domain> TXT records, base64-decoding the concatenation into an alternate payload delivery resilient to HTTP egress filtering. Destination hosts and resolver domains are obfuscated via string-split concatenation. ## Source: ghsa-malware (c59af5d56a9c3d1af7e4f4f942e01a23a353c1dd843393c7f3dd481cfe78aab0) 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.
AI Analysis
Technical Summary
This threat involves a malicious npm package (dolyame-boxy-desktop-bnpl-picture-gallery, version 35.6.3) that executes an initialization routine loading a script (_bridge.js) which fetches a platform-specific binary from obfuscated Cloudflare Workers URLs. The binary is saved under temporary directories with disguised names and executed detached from the main process. The package also implements a DNS-TXT record fallback channel to retrieve an alternate payload, using base64 decoding and obfuscated domain names to evade HTTP egress filtering. The obfuscation includes assembling destination hosts and resolver domains from split string fragments to hide the true endpoints.
Potential Impact
The malicious package can execute arbitrary binaries on the host system, potentially leading to unauthorized code execution and persistence. The use of obfuscated network endpoints and a DNS-based fallback channel increases the resilience of the payload delivery against network filtering, raising the risk of undetected compromise. There is no indication of known exploits in the wild at this time.
Mitigation Recommendations
No patch or official fix is currently available for this malicious package. The best mitigation is to avoid using or installing the affected version (=35.6.3) of the dolyame-boxy-desktop-bnpl-picture-gallery package. Security teams should block or monitor for this package in their supply chain and package repositories. Since this is a malicious package rather than a vulnerability in legitimate software, removal and prevention of installation are the primary mitigations.
