one major campaign in the past three weeks.
When malware spam drops, I notice that fake pharma spam pops up instead, and furthermore malware spam runs are hardly ever at weekends when pharma takes over. And yes.. there's been an uptick of pharma spam lately which follows the pattern.
This malware spam run has been going on for months now, with a few breaks of a few weeks each time. I can't believe that anything fundamental has changed. So stay alert!
