{"schema_version":"1.7.4","id":"MAL-2026-10933","published":"2026-07-20T00:00:00Z","modified":"2026-08-05T07:08:56.350202863Z","summary":"Malicious code in twilio-deploy (npm)","details":"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.\n\nThe 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.\n\nThe 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.\n\n---\n_-= Per source details.

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.\n","affected":[{"package":{"name":"twilio-deploy","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["99.99.99","99.99.100"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"1e53f49081bcfa36cb83abaa9fcfdec5b1ef99d515f40a766b0de9e1e5d03f09","tlsh":"5f1148f553f5ad700bb59384b18aac1553b3f01473079cf099d851652bd827425f26f9"}],"package_integrity":[{"filename":"twilio-deploy-99.99.99.tgz","hashes":{"sha1":"139f94f0e5e6bf0ea453c029844530d5ef4061d5","sha512_sri":"sha512-UjzTBavnFgISti/+Dq/WBD0J0OIzMO1wJ9lWQcj8OijDCMB5h2MF1ee6yIDSJcq4TcE5Bc26SpUuoJ3EjDHoWw=="}}]},"iocs":{"domains":["webhook.site","2b22ede784d5.oast.fun"],"urls":["https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f"]}}}],"references":[{"type":"WEB","url":"https://www.npmjs.com/package/twilio-deploy"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/twilio-deploy/v/99.99.99"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/twilio-deploy/v/99.99.100"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-011101","import_time":"2026-08-04T21:33:16.772828297Z","modified_time":"2026-08-04T21:32:33Z","sha256":"64b1e3e96271384ceafb277978fe65ca3e89fd42bc59fbc82e5c17be66e0ba31","source":"amazon-inspector","versions":["99.99.99"]},{"id":"IN-MAL-2026-013301","import_time":"2026-08-05T07:06:40.350948833Z","modified_time":"2026-08-05T06:03:31Z","sha256":"70c4d709ca9d653cb4c5cb2b35aca854d264cf7fda431259c255c2f738adf8c5","source":"amazon-inspector","versions":["99.99.100"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
