Not sure if this is the correct forum for this, but my web site is being hit with a lot of suspicious entries. Every day, I get a lot of hits where the User Agent is always "Mozilla/4.0 (compatible; Synapse)". They are almost always from different IP addresses, and all are from suspicious countries. The querystring almost always contans a "-1", such as: "n=-1%27"
I've blocked all requests that contain the above user agent, but am worried that there may be legitimate attempts with this browser.
Can anyone shed any light on what this is?
