MAL-2026-13324 Malicious code in dolyame-boxy-independent-bnpl-partners (npm)

On require of the package, index.js loads platform.js, which assembles attacker-controlled hostnames via array-split-and-join obfuscation (oob-worker.*.workers.dev variants and sdk/ext/pkg/net.dl.wel1.ru), fetches a platform-specific binary over HTTPS with a DNS-TXT base64 fallback channel, writes it to /var/tmp or %TEMP% under disguised names such as.cache<hex> or dotnet_diag_<hex>.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Cover-story identifiers such as analytics_state and a DISABLE_TELEMETRY opt-out are used to frame the behavior as telemetry. The package name impersonates a Russian BNPL partner integration, and none of the shipped code implements that stated purpose.

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.
