The twilio-deploy package is one of four byte-identical dependency-confusion squats of Twilio's npm namespace published by user 'yuva2210' (maintainer email charankumarj2004@gmail.com), all at the sentinel version 99.99.99 chosen to outrank any internal/private version and win resolution against a private registry... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-08-05T07:45:09.211Z - **Finished:** 2026-08-05T07:45:09.211Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to twilio-deploy@99.99.100. The same advisory and Firewall decision cover these 2 recorded versions: 99.99.99, 99.99.100. - Avoid installing twilio-deploy@99.99.100. 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: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The twilio-deploy package is one of four byte-identical dependency-confusion squats of Twilio's npm namespace published by user 'yuva2210' (maintainer email charankumarj2004@gmail.com), all at the sentinel version 99.99.99 chosen to outrank any internal/private version and win resolution against a private registry. The npm description is empty and the package provides no legitimate functionality; the name mimics a plausible internal Twilio package so that a misconfigured resolver installs this public lookalike instead of the intended private dependency. The package declares a postinstall hook ("node index.js") that executes automatically on a bare npm install with no consent gate. The bundled index.js payload (1,185 bytes, sha256 prefix c324d579006df4c5, identical across all four packages) performs environment reconnaissance: it collects the npm package name and version, os.hostname(), the OS username (os.userInfo().username), the home directory path (os.homedir()), the current working directory, os.platform(), os.arch(), NODE\_ENV, and the CI flag. It serializes this to JSON and exfiltrates it via HTTPS POST to a hardcoded anonymous dead-drop at https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f (the same collector UUID across all four packages). On request error the payload falls back to a redundant out-of-band callback to 2b22ede784d5.oast.fun over HTTP, ensuring the beacon lands even where HTTPS egress to webhook.site is blocked; errors on that path are swallowed. The collected cwd/homedir/username/CI/NODE\_ENV set is reconnaissance targeting internal build environments and their filesystem layout. All four packages (twilio-serverless, twilio-assets, twilio-deploy, twilio-internal) were published by the same maintainer with an identical payload and the same collector endpoint. --- \#\# Source: amazon-inspector (64b1e3e96271384ceafb277978fe65ca3e89fd42bc59fbc82e5c17be66e0ba31) Package name typosquats 'twilio' and is published at version 99.99.99, the classic dependency-confusion shape used to intercept internal-package resolution. On npm install, the declared postinstall hook runs index.js, which collects host and user identifiers (os.hostname(), os.userInfo().username, os.homedir(), cwd, os.platform(), os.arch(), npm\_package\_name, npm\_package\_version, NODE\_ENV, and CI environment variables) and POSTs them as JSON to a hardcoded https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f collector, with a fallback GET to 2b22ede784d5.oast.fun as an out-of-band callback. The destination is not configured by the installer and is unrelated to the Twilio publisher; the effect is automatic reconnaissance beacon on any machine that installs the package. ## 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:** twilio-deploy - **Ecosystem:** npm - **Version:** 99.99.100 - **Version published:** 2026-07-20T08:18:52.912Z - **Package first seen:** 2026-08-04T22:30:08.797Z - **Package last seen:** 2026-08-05T07:45:09.211Z - **Known versions:** 2 - **Latest version:** 99.99.100 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [WEB]() - [PACKAGE]() - [PACKAGE]()
