# MAL-2026-12993: Malicious code in bnpl-blocks-mobile-bnpl-image-plus-text (npm) - **Type:** Malicious package - **Package:** `bnpl-blocks-mobile-bnpl-image-plus-text` (npm) - **Published:** 5 Aug 2026 ## What is MAL-2026-12993? MAL-2026-12993 is a malicious package in bnpl-blocks-mobile-bnpl-image-plus-text, published on 5 Aug 2026. ### Official description 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. 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. ## What should I do about MAL-2026-12993?
