Sharp drop in JScript attacks

[Peter Lemieux]

This isn't directly pertinent to MailScanner, but since you all are pretty 
experienced in fighting malware, I thought I'd ask.

I have a healthcare client who was being deluged with JScript attacks.  On one 
day alone, the quarantine directory in MailScanner exceeded 7 GB in size.  For 
weeks MS was blocking thousands of JS files.  Now the attacks have abruptly 
stopped.  Has anyone else seen this behavior, or have any ideas about what 
might have happened?

Thanks!

Peter
