GARM

The scanner at the gate.

GARM is 100% PHP: it installs in two minutes on any hosting — managed, shared, VPS — with no shell access and no Python. It checks the integrity of core, plugins and themes against the official WordPress.org checksums: if the site was already infected, GARM sees it all the same.

01 · Why GARM

The hound at the gate of WordPress.

Serious scanners require shell access — but 70% of WordPress hosting doesn’t have it. GARM covers exactly that space: pure PHP, integrity via official checksums, almost zero false positives.

Official integrity
Compares core, plugins and themes against WordPress.org checksums. Catches injections even if the site was already infected.
Signatures + heuristics
Webshell and backdoor patterns (eval / obfuscated base64), run only on non-official files: custom, uploads, plugins not in the repo.
Known-good whitelist
Files identical to the original are skipped: legitimate libraries aren’t even scanned. Almost zero false positives.
Quarantine & restore
One click moves the file to a protected area, with a backup. False positive? You restore it. No automatic action: you decide.
Runs anywhere, zero shell
100% PHP: no shell, no Python. It installs even on managed hosting, where the Wordfence CLI can’t go.
EU & open source
GPL-2.0, backend in the EU (Estonia), signatures from open sources. No US Cloud Act, no black box.
02 · Installation
