Hello,
I've gotten a recent avalanche of access attempts. Over 400 in the last few days.
The target URLs contain html such as %22, %29, %2F, etc. Always in long combinations and between words like PROCEDURE, CONCAT, WHERE, SELECT, ANALYSE, UPDATEXML.
example:
(domain)/index.php?id=41%22%2F%2A%2A%2FPROCEDURE%2F%2A%2A%2FANALYSE%28EXTRACTVALUE%286441%2C%2F%2A%2150000CONCAT%2A%2F%280x5c%2C%2527~%2527%2C%28%2F%2A%2150000SELECT%2A%2F%28ELT%286441%3D6441%2C1%29%29%29%2C%2527~%2527%29%29%2C1%29--+-&Itemid=41&option=com_content
The IPs are random, but the attempts come in batches. Several over a short period, a small break, then repeat. They all use the same article ID.
Although there are a few exceptions, the IPs are usually used once. During this pattern, only 3 IPs have been banned.
I tested one of the URLs and it resulted in a 403 error.
The site is in someone's crosshairs, but I don't know if this is an acceptable level of threat or something that needs a heightened awareness.
Thanks!
