Renesys published a very interesting paper detailing the impact of the power outage on connectivity in the North East.
The Nachia worm is still spreading fast. While this worm is frequently refered to as a 'good worm', it should be noted that the impact of this worm is worse than 'Blaster'. While this worm cleans up blaster infected machines, it causes network disrubtion due to its agressive pinging. Also, note that this virus will install a back door and it will scan for machines that are vulnerable to the WebDav IIS exploit. In so far, this worm may just remove the Blaster virus to protect itself, like many 'auto rooters' do.
Despite the best efforts of system admins world wide, users are still clicking on e-mail attachments. We strongly recommend attachment stripping on mail gateways. Please note, that the 'From' address is spoofed. Do not send auto replies to senders, as this will just worsen the email flood caused by Sobig F. As other Sobig variants, this one includes the ability to update the worm remotely, backdoors and a full set of other evilness.
