Summary

The Sober.W worm was found on November 15th, 2005. This Sober variant is similar to Sober.T, that appeared yesterday:

https://www.f-secure.com/v-descs/sober_t.shtml

Like the previous variants, this one sends itself inside a ZIP archive as an attachment in email messages with English or German texts. We also received several different droppers for this worm variant. They were apparently created by the worm author manually. They are all detected as 'Sober.w' or 'Sober.W.dr'.
