What is MAL-2026-13012?
MAL-2026-13012 is a malicious package in bnpl-blocks-playwright, published on 5 Aug 2026.
Official description
On require('bnpl-blocks-playwright'), index.js loads bridge.js which downloads a platform-specific binary from obfuscated Cloudflare Workers subdomains (oob-worker.cf10{0,1,2,3}-*.workers.dev, reassembled via array.join('')) with DNS TXT fallback to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes it to /tmp or %TEMP% under a disguised name (dotnet_diag.exe,.cache_), chmod 0755s it on Unix, and spawns it detached via /bin/sh -c or cmd.exe. Hostnames and API identifiers (child_process, chmodSync) are split-concatenated at runtime to evade static analysis. The package is advertised as a Playwright/BNPL adapter and has no legitimate need to fetch and execute native binaries from anonymous Cloudflare Workers subdomains on import.
What should I do about MAL-2026-13012?
