Summary: Malicious code in dolyame-boxy-mobile-bnpl-card-gallery (npm)
Details: Source: amazon-inspector (d25f027b45e1dd0483fdacb92c8af5b25302f2785de7a7a5c259b8d535597d80) On require of the package, _bootstrap.js fetches an opaque binary over HTTPS from a rotating list of Cloudflare Workers subdomains (with a DNS-TXT chunked-retrieval fallback to *.wel1.ru), writes it to /var/tmp/.cache_<rand> or %TEMP%/dotnet_diag_<rand>.exe, chmods 0755, and spawns it detached via /bin/sh -c or cmd. Destination hostnames and API names are string-concatenation-obfuscated (host fragments joined via.join(""), require("child_"+"process"), fs["chmod"+"Sync"]) to evade static inspection. The destinations are anonymous workers.dev endpoints unrelated to the package's stated purpose ("mobile SDK"); no hash or signature verification is performed and the payload path uses hidden dot-cache or.NET-diagnostic-lookalike names. lib/telemetry.js ships a duplicate copy of the drop-and-exec routine wrapped in an "Analytics SDK" comment block as an alternate payload carrier.
