bui-react-10themesnpm
bui-react-10themes is a confirmed malicious npm package (MAL-2026-15529) that executes malicious code on install (malicious version 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bui-react-10themes (npm)
What this malware does
package.json declares a dependency whose key equals this package's own name (bui-react-10themes) and whose value is a bare HTTPS URL (https://repo.securityctrl.com/bui-react-10themes) rather than a registry version range. There is no version pin and no integrity hash. On npm install, npm fetches whatever tarball is served from repo.securityctrl.com and installs it, executing any lifecycle scripts it contains. The shipped in-tree code is an inert stub, so the manifest edge is the entire installed surface. The self-name pattern (dependency confusion shape) combined with the implausibly high 45.0.0 version is consistent with an attempt to win resolution against an internal package of the same name.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for bui-react-10themes (version 45.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bui-react-10themes across your stack and pipelines.
If you installed it — respond
Remove bui-react-10themes from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If bui-react-10themes was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks bui-react-10themes before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
