Summary
Malicious code in @flexmr/ui (npm)
Details
`@flexmr/ui@99.99.99` runs `node beacon.js preinstall`, `node beacon.js install`, and `node beacon.js postinstall` during installation. These lifecycle scripts send the package name, lifecycle event, a fixed token, and host identity details to `177.7.60.239:48080` and encode the hostname in a DNS query under `oob.recon.dev`, probing whether a build resolves the package from the public npm registry; it was published on 2026-10-13.
