Advisory published Updated
dolyame-boxy-atom-bnpl-email-form is a confirmed malicious npm package (MAL-2026-12363) that executes malicious code on install (malicious version 20.3.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-atom-bnpl-email-form (npm)
What this malware does
On require of the package's main, index.js side-loads _runtime.js which selects a per-platform payload path, fetches an opaque binary from string-split obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev), writes it to /var/tmp or %TEMP% with a disguised filename (.cache_<hex>, dotnet_diag_<hex>.exe, .analytics_state), chmods 0755, and spawns it detached via child_process.spawn('/bin/sh') or spawn('cmd'). When the HTTPS mirrors fail, _runtime.js falls back to a DNS TXT covert channel: it resolves c.<domain> for a chunk count, iterates <i>.dl.well1.site TXT records (tin/tina/ldr/win subdomains), concatenates and base64-decodes them into the payload, then writes and spawns it. Host names, fallback DNS domains, and the string 'child_process' are assembled from split string arrays at runtime to evade static analysis. There is no version pinning, hash check, or signature verification, and the destinations are not the publisher's infrastructure. Cover-story framing as an 'Analytics SDK' with a DISABLE_TELEMETRY opt-out does not match the actual fetch-decode-write-chmod-spawn behavior.
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
Search your lockfiles and build artifacts for dolyame-boxy-atom-bnpl-email-form (version 20.3.3).
If you installed it — respond
Remove dolyame-boxy-atom-bnpl-email-form 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-atom-bnpl-email-form was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks dolyame-boxy-atom-bnpl-email-form-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
