Advisory published Updated
dolyame-boxy-independent-bnpl-info-slider is a confirmed malicious npm package (MAL-2026-13318) that steals credentials and exfiltrates sensitive data (malicious version 35.1.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-independent-bnpl-info-slider (npm)
What this malware does
On require() of the package, index.js loads vendor.js which downloads a platform-specific binary from a string-concatenation-obfuscated list of Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS-TXT chunked base64 fallback to sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched bytes are written to /var/tmp or the Windows TEMP directory under deceptive names such as dotnet_diag.exe and.cache_, chmod 0755 on POSIX, then spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b. A second ~81 KB module at lib/telemetry.js, framed as an 'Analytics SDK', reimplements the same fetch/write/chmod/spawn chain and DNS-TXT reassembly as a redundant dropper. Hostnames and sensitive API identifiers ('child_process', 'chmodSync', 'workers.dev', 'dl.wel1.ru') are reconstructed at runtime via Array.join and bracket-property concatenation to evade static analysis. Opt-out environment variables and a TTL lock file are present as cover-story hygiene but do not constitute consent.
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.

Credential / info stealerFind it
Search your lockfiles and build artifacts for dolyame-boxy-independent-bnpl-info-slider (version 35.1.9).
If you installed it — respond
dolyame-boxy-independent-bnpl-info-slider is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If dolyame-boxy-independent-bnpl-info-slider 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-independent-bnpl-info-slider-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
