bnpl-blocks-atom-bnpl-popup @35.4.7

Summary

On require() of this package, index.js loads _shim.js which assembles obfuscated non-publisher URLs by joining split string fragments (resolving to a *.workers.dev host, with a DNS-TXT covert-channel fallback under a.ru domain that reconstructs a payload from base64-encoded TXT records at c.<domain> and <i>.<domain>). _shim.js downloads a platform-specific binary, writes it to /tmp or %TEMP% under a disguised filename (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmods 0755, and spawns it detached via cp.spawn('/bin/sh', ['-c', fp+' &'], {detached:true}).unref() (or the cmd equivalent). No hash or signature verification is performed. A second copy of the dropper is shipped in lib/telemetry.js (labeled as an 'Analytics SDK') using the same shape with split-string API names such as require('child_'+'process') and fs['chmod'+'Sync']; it is not wired into the current entry point but stages the same capability. The destination hosts are not first-party to the package, and the string-splitting plus DNS-TXT channel are anti-analysis tradecraft rather than legitimate telemetry configuration.
