Phoenix Studio

Convert indexed Sigma rules into analyst-ready detections.

This studio is built around Phoenix's own rule corpus, not a blank editor. Search by title or rule id, choose a live sigma-cli backend, then reveal pipelines only when you actually need them.

title: Potential Exploitation of CVE-2025-5054 or CVE-2025-4598
id: 33b3cfb1-574e-44b9-b527-fbf9303b9d7b
status: experimental
description: |
    Detects attempts of an attacker to enable core dumps for set-user-ID (SUID) processes by modifying the system file /proc/sys/fs/suid_dumpable, typically by setting its value to 1 or 2.
    Enabling this feature allows memory dumps (core dumps) of SUID processes, which usually run with elevated privileges.
    These dumps may contain sensitive information such as passwords, cryptographic keys or other secrets.
    CVE-2025-5054: Information leak via core dumps from SUID binaries using apport.
    CVE-2025-4598: Information disclosure in systemd-coredump due to insecure handling of SUID process memory dumps.
