dolyame-boxy-independent-bnpl-preset-containernpm
dolyame-boxy-independent-bnpl-preset-container is a confirmed malicious npm package (MAL-2026-13326) that executes malicious code on install (malicious version 35.3.7). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-independent-bnpl-preset-container (npm)
What this malware does
index.js require()s platform.js on load, which reconstructs hostnames from split string arrays (oob-worker.cf10*-*.workers.dev and sdk.dl.wel1.ru) to hide destinations from static inspection, then HTTPS-fetches an opaque binary payload from those hosts with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under a randomized hidden filename (.cache<rand> / dotnet_diag_<rand>.exe), chmod 0755, then spawned detached via /bin/sh -c or cmd.exe (_platform.js line 119-125). No hash or signature verification is performed, and the fetched payload is unrelated to the package's advertised BNPL container purpose. A.analytics_state marker file and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK opt-out flags provide cover-story framing over the loader. The dropper fires at module require time.
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.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dolyame-boxy-independent-bnpl-preset-container (version 35.3.7). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dolyame-boxy-independent-bnpl-preset-container across your stack and pipelines.
If you installed it — respond
Remove dolyame-boxy-independent-bnpl-preset-container from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If dolyame-boxy-independent-bnpl-preset-container was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks dolyame-boxy-independent-bnpl-preset-container before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
