Which versions of streak-calc-math are malicious?

The following npm versions of streak-calc-math are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate streak-calc-math if I installed it?

streak-calc-math is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed streak-calc-math — how do I know if it already compromised me?

If streak-calc-math 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 streak-calc-math part of a known attack campaign?

Yes — streak-calc-math is associated with the IN-MAL-2026-013432 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 streak-calc-math 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 streak-calc-math (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging streak-calc-math across your stack and pipelines.

What this malware does

[email protected] bundles a Linux x86_64 ELF at dist/math-calc.bin and launches it unconditionally when the package is imported. The top-level IIFE in dist/index.mjs chmod 0755's the binary and cp.spawn's it detached with piped stdio. A sha256 'integrity verification' against a placeholder constant is a decoy: when the computed hash does not match, execution proceeds anyway; only a log line changes. The ELF is a full RedShell remote-access implant beaconing to hardcoded C2 IP 217.60.77.63 (SECURE_BEACON|...|REDSHELL framing). Operator capabilities include arbitrary shell execution via /bin/sh and /bin/bash, SOCKS5 proxy, TCP port-forward, tunnel relay, and remote payload staging that curls additional ELFs and shellcode over plain HTTP from http://217.60.77.63/Others/ and /SC/ into /tmp or an anonymous memfd (memfd_create syscall 319 invoked via python3 ctypes) and executes them. Operator commands /ssh_keys, /creds, /dbfind, /download, /dataextract and a chunked BIGEXTRACT upload path harvest ~/.ssh keys, credential files, and database files and POST them to http://217.60.77.63/api/extract-receive. Persistence is installed via /redshell persist by writing a user systemd unit at ~/.config/systemd/user/svc-update.service (Description='System Update Service', ExecStart=/proc/self/exe, Restart=always) and enabling it with systemctl --user. The package name and 'high-performance math accelerator' framing are a cover story for a backdoor with no legitimate math functionality.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for streak-calc-math (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging streak-calc-math across your stack and pipelines.
If you installed it — respond
streak-calc-math is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If streak-calc-math 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 streak-calc-math 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.
