- dolyame-boxy-mobile-bnpl-card-gallerynpm package containing malicious code in _bootstrap.js and lib/telemetry.js
The npm package dolyame-boxy-mobile-bnpl-card-gallery was found to contain malicious code designed to execute arbitrary binaries on systems where the package is imported. Upon require, the _bootstrap.js file fetches an opaque binary over HTTPS from rotating Cloudflare Workers subdomains, with a DNS-TXT chunked-retrieval fallback to *.wel1.ru domains.
The malicious code writes the downloaded binary to obfuscated paths (/var/tmp/.cache_ or %TEMP%/dotnet_diag_.exe), sets executable permissions (chmod 0755), and spawns it detached via shell commands (/bin/sh -c or cmd). The destination hostnames and API calls are string-concatenation-obfuscated to evade static inspection tools.
A duplicate copy of the drop-and-exec routine is also present in lib/telemetry.js, wrapped in an "Analytics SDK" comment block to disguise its purpose. The destinations are anonymous workers.dev endpoints unrelated to the package's stated purpose as a mobile SDK, and no hash or signature verification is performed on the downloaded payload.
The malicious package was identified by the OpenSSF and cataloged as MAL-2026-13338.
