Which versions of fundraiserservpp are malicious?

The following npm versions of fundraiserservpp are flagged malicious: 1.9.0, 2.0.0. Treat any of these as compromised.

How do I remediate fundraiserservpp if I installed it?

fundraiserservpp 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.

I already installed fundraiserservpp — how do I know if it already compromised me?

If fundraiserservpp 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.

Is fundraiserservpp part of a known attack campaign?

Yes — fundraiserservpp is associated with the IN-MAL-2026-014837, IN-MAL-2026-015807 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find fundraiserservpp across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for fundraiserservpp (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging fundraiserservpp across your stack and pipelines.

What this malware does

[email protected] runs node index.js as a preinstall lifecycle script on npm install. The script collects host metadata from the installer machine — os.hostname(), os.platform(), os.arch(), the user home directory path, and configured DNS servers — and issues an HTTPS POST to a hardcoded Burp Collaborator subdomain (mrh99ucv1u3kyeba1020ae2t7kdc12pr.oastify.com/hit) with that data as a JSON body. The beacon fires automatically at install time with no user interaction. The destination is an attacker-controlled out-of-band interaction endpoint typical of dependency-confusion reconnaissance, confirming to the operator that the package name was successfully resolved and installed inside a target build environment.

Backdoor / remote access

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for fundraiserservpp (2 malicious versions).

Did it already run?
If fundraiserservpp 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 fundraiserservpp 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.
