Situation
The Joomla site started displaying fake content and suspicious files appeared on the server. The owner only noticed something was wrong when visitors reported strange messages.
Symptom
Defacement content and malicious files scattered throughout the installation — a classic sign that someone has gained the ability to upload to the server.
Diagnosis
The input was a vulnerable plugin that allowed file uploads. Malicious scripts were inserted through it. Joomla itself was not "hacked from the inside" — the attacker exploited a known weakness in the extension.
Decision
We cleaned up the malicious code, then — most importantly — closed the vector : restricted execution at the server level, locked down the vulnerable path, and hardened the installation. Cleaning without closing the entry would have led to reinfection within a few days.
Result
The site was cleaned and restored to normal, and the entrance through which the infection came was closed — without recurrence.
How to prevent
Regular extension and core updates, a security layer (WAF + malware scanner), and locking down sensitive paths keep Joomla safe. It's a standard part of our hosting.
