For the moment the Asprox SQL injection attacks seem to have stopped, although infected sites are still infected and need to be secured as soon as possible.
So, does this mean that the bad guys have given up? Well, no.. but there are probably thousands of sites out there which are still infected, so from that point of view they will still be getting "hits" to their malware sites.
Perhaps the answer is this - the people behind the SQL injection attacks are doing something else. Two very newsworthy events happening over the past few days have been the war in Georgia and the Beijing Olympics. Dancho Danchev reports that the RBN have been actively involved in attacking Georgian sites, including using SQL injection attacks. F-Secure report that Chinese sites have been attacked since the run-up to the Olympics started.
It might well be that these Asprox attacks will be quiet for a couple of weeks, but it is likely that general SQL injection attacks will ramp up again soon.
