Repeated hacks almost always mean one thing: the way in was never found and closed. Cleaning the malware without finding the entry point just resets the clock - the attackers walk straight back in.
The usual reasons
An outdated plugin or theme with a known hole that was never patched. A stolen or reused password that was never changed. A backdoor file left behind by the last cleanup. Malware hiding in the database, surviving every file-level cleanup. Or an insecure neighbour site on shared hosting.
Why cleaning isn't enough
Automated attacks run constantly and they don't get discouraged. If the vulnerability, the password, and the backdoors aren't all handled, reinfection is a matter of time - often days. A proper cleanup ends with hardening: patching, rotating every credential, and removing anything that shouldn't exist.
How to break the cycle
Find out how they got in - the logs usually tell you. Change every password, including the database and hosting. Update or replace whatever let them in. Then keep the site current afterwards, because an unpatched site is simply a queue for the next attempt. Our security checklist covers the full hardening pass.
