OpenSSF/OSV advisory MAL-2026-10700 confirms this npm version as malicious. On npm install, the package's postinstall script decodes base64-encoded shell payloads and executes them via an obfuscated child\_process.exec lookup (require('ch'+'il'+'d\_p'+'rocess')\['e'+'xec'\]). The shell payload reads ~/.aws/credentials, ~/.ssh/id\_rsa, ~/.ssh/authorized\_keys, ~/.ssh/known\_hosts, ~/.bash\_history, the full process environment, and host identifiers (hostname, whoami, id, sudo -l), then POSTs the... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-07-16T15:50:09.199Z - **Finished:** 2026-07-16T15:50:09.199Z - **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 time-format-kit@1.0.2. The same advisory and Firewall decision cover these 2 recorded versions: 1.0.2, 1.0.1. - Avoid installing time-format-kit@1.0.2. 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% On npm install, the package's postinstall script decodes base64-encoded shell payloads and executes them via an obfuscated child\_process.exec lookup (require('ch'+'il'+'d\_p'+'rocess')\['e'+'xec'\]). The shell payload reads ~/.aws/credentials, ~/.ssh/id\_rsa, ~/.ssh/authorized\_keys, ~/.ssh/known\_hosts, ~/.bash\_history, the full process environment, and host identifiers (hostname, whoami, id, sudo -l), then POSTs the base64-encoded contents over plain HTTP to a hardcoded Burp Collaborator subdomain at pwpzhsrbtvmfqrqr7onqcwnrcii960up.oastify.com. Additional payloads issue curl requests through the installer host to http://tst.woa.com/flag.html and http://tst.woa.com/ssrf\_forward.php with an oastify-subdomain host parameter, and POST the response bodies back to the same collaborator endpoint, using the installer as an SSRF relay. The package name ('time-format-kit') has no functional relationship to the observed behavior. \#\# Source: ossf-package-analysis (013929714a8a46ad664ac923c9ce315df1b9351993cc7d2d06a325d8f0c49009) The OpenSSF Package Analysis project identified 'time-format-kit' @ 1.0.2 (npm) as malicious.
