We have received a report of a large distributed SQL Injection Scan from a reader. Behavior of scan is being reported as 9000+ Unique IPv4 Addresses and sends 4-10 requests to lightly fuzz the form field. Then the next IP will lightly fuzz the second form field within the same page and the next IP the next form field. Looks to be targeting MSSQL and seeking version. The reader reports that this scan has been going on for several days. Sample Payload:
The User Agent String for all of the attacking IPs is always User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0) There does not seem to be a referrer page either.
If you are seeing this activity and can report it please let us know.

I observed similar activity about a week ago. However in my case there were less than 100 unique source IPs, all belonging to a particular shared hosting provider inside the continental US. The activity continued for about 4 days before stopping.

It's turned up in a mass grep of IIS logs.
145 Unique IP Addresses, however they all belong to the same AS allocated to a provider in the US, (I presume the same one as AB mentioned) Doesn't seem like the injections were successful. Will keep an eye out though. |

We also saw a huge group of attempts at sql injection, while perusing event viewers for last week. All from the same shared hosting provider in Pennsylvania. There were several hundred attempts all with LOONNGG urls with multi "at at version" strings.
