    Summary: Malicious code in bnpl-blocks-playwright (npm)

    Details: Source: amazon-inspector (b85856c1395372c88e148fdabb77be27f0556ad68ba3eb7f5c62d063a9154607) 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.
