What this malware does

On require of the package, compat.js assembles remote endpoint hostnames from split string arrays (e.g. oob-worker.cf10x-*.workers.dev) and includes a DNS TXT-record base64 fallback channel over c.<domain> and numbered subdomains of dl.wel1.ru. It downloads a platform-specific binary from those attacker-controlled hosts with no hash or signature verification, writes it to a temp path under a masquerading name (dotnet_diag.exe on Windows,.cache_ on Unix), chmods it 0755, and spawns it detached via cmd.exe /c start /b or /bin/sh -c. The dropper runs on module load with a TTL stamp to suppress re-execution. Behaviors observed include platform gating, cover-story naming, string-concatenation obfuscation of the C2 hosts, and a covert DNS TXT-record fallback for endpoint resolution.

Detection & response playbook

Backdoor / remote access

  1. Find it

    Search your lockfiles and build artifacts for bnpl-blocks-mobile-bnpl-image-plus-text (version 35.3.2).

  2. If you installed it — respond

    bnpl-blocks-mobile-bnpl-image-plus-text establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If bnpl-blocks-mobile-bnpl-image-plus-text 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.
