Has anyone else noticed an increase in bot spam? My black list has grown by about 1/3 in the last month.
Yes, I just checked the numbers for the last few weeks. Volume was in line with the weekly average for March through two weeks ago, last week shows a 55% increase over the March levels, and this week is above 96% already with two days to go before a log rotation. Nearly all of it is coming from the typical set of compromised machines.
Does this actually amount to anything more than a curiosity? From my perspective, it's just more of the same. For what it's worth, the SA numbers haven't changed significantly -- it's not even getting a crack at this latest spate, the SMTP checks are doing the job.
