Which versions of calculator-c08d6d50f5964131 are malicious?

The following PyPI versions of calculator-c08d6d50f5964131 are flagged malicious: 1000.0.2. Treat any of these as compromised.

How do I remediate calculator-c08d6d50f5964131 if I installed it?

calculator-c08d6d50f5964131 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 calculator-c08d6d50f5964131 — how do I know if it already compromised me?

If calculator-c08d6d50f5964131 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 calculator-c08d6d50f5964131 part of a known attack campaign?

Yes — calculator-c08d6d50f5964131 is associated with the GENERIC-examples-with-revshell campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
