The number of request strings like this one seems to have increased over the last weeks. They all have in common, that they contain a combination of google adwords / google adsense parameters and sql injection.
The decoded value of the request string is
/?gclsrc=aw.ds&gclsrc=aw.ds& and 1>1
I can see
- a duplicate gclsrc parameter
- an sql injection attempt
… but why this combination? Is it a technique to grab adsense revenues while sqli probing?
