What it checks
Shared libraries force-loaded via /etc/ld.so.preload or LD_PRELOAD.
Why it matters
Commonly abused to inject malicious code into normal binaries for hooking/hiding.
How to fix
Verify/remove entries, confirm the .so origin, run integrity checks (rpm -V/debsums).
InfraGuard runs all 36 checks across your servers at once and grades each host A–F.
Track these versions on your own servers
InfraGuard collects installed software versions from every server and flags the ones with known vulnerabilities. Self-hosted — nothing leaves your network.
