High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% @help-forms/application-aff@3.4.3 ships a heavily obfuscated postinstall script (scripts/postinstall.js, obfuscator.io fingerprints: rotated string array, base64+decodeURIComponent decoder, hex-named identifiers, self-defending wrapper) that runs automatically on \`npm install\`. The script ascends from process.cwd() to locate a project root (package.json/.git/node\_modules markers), DJB-hashes that path as a per-project cache key under os.tmpdir(), supports a \`RECON\_ONLY\` env-var mode, and uses a 7-day cache marker so the dropper only fires once per project. It then detects os.platform(), constructs a URL of the form \`\/\/\\` from strings hidden in the rotated array, HTTP-fetches a platform-specific binary, writes it under os.tmpdir(), and spawns it with \`{detached:true, stdio:'ignore'}\` followed by \`.unref()\`. There is no hash or signature verification, no pinned URL, and no documentation of the fetched binary's purpose. The package itself is a decoy: package.json advertises an \`Internal HTTP client\` for the \`Help-Forms Platform Engineering\` team and points at non-resolving \`\*.help-forms.io\` domains, but the tarball only contains README.md, package.json, scripts/, and dist/. dist/index.js does \`require('../src/index.js')\` while no \`src/\` directory ships, so any consumer of the advertised \`createClient\`/\`get\`/\`post\` API will hit a require error — but only after the postinstall dropper has already executed. The combination of obfuscation, install-time outbound fetch from a hidden URL, opaque platform-specific binary execution as a detached background process, project-fingerprinting recon, and decoy library shape is the canonical supply-chain dropper pattern. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @help-forms/application-aff - **Ecosystem:** npm - **Version:** 3.4.3 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 3.4.3 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]()
