thebatlab writes "Help Net Security has an interesting look at security in Windows during 2003, with various blurbs from related parties at Microsoft as well as security 'bigwigs' such as Russ Cooper. It's interesting to read the comments from external parties, as they tend to be very reasoned comments and don't simply attack away over recent 'indiscretions' and 'security lapses' Microsoft has had over the year."

Sgt York writes "In a NYT article (republished in the Houston Chronicle, no subscription required) experts at CERT, F-secure, Trusecure, and the Hall of Justice (see article) think that SoBig.F is a spam scheme in the making. They say that SoBig.F is the 6th variant in an ongoing experiment with the possible goal of setting up a distributed spam network, to be rented out to the highest bidder. If that is their goal, they are well on their way. Another disturbing note in the article is that "In the case of four of the six programs, a new version was launched immediately after the self-timed expiration date of the preceding one". SoBig.F expires in two weeks. "

A new worm seems to be running rampant Unlike Code Red, it attempts to hit boxes with many different exploits (including what looks like an attempt to exploit boxes still rooted by Code Red). It looks like each IP tries 16 attempts on its neighbors. There is also a new mail worm mailing WAV files or something with bits of what appears to be the registry... it may or may not be related. Got any words on this? Shut down those windows boxes and stop opening attachments. And make that 21. Got another one while writing this story. All my hits are coming from 208.n.n.n (where I am) I'm sure it'll keep moving to nearby boxes. Update: 09/18 16:40 GMT by J : It now has a name: "Nimda." More info here, here, and here.

Here are examples of the requests it's sending:

GET /scripts/..%%35%63../winnt/system32/cmd.exe?/c+dir
GET /msadc/..%255c../..%255c../..%255c/..%c1%1c../..%c1%1c../ ..%c1%1c../winnt/system32/cmd.exe?/c+dir
GET /_vti_bin/..%255c../..%255c../..%255c../winnt/system32/cmd.exe?/c+dir

While writing this story I was hit a total of 4 times, 16 GET attempts per attack. In only 4 minutes. Also of interest, My desktop has now been hit about 500 times today, all from 208.x.x.x IPs. This might be really bad. I still haven't read anything about this anywhere else, so you heard it here first ;)

Update Web servers compromised by this worm apparently attach a "readme.eml" to all web pages served... and due to a bug in IE5, it will automatically execute the file! Yay Internet Explorer!
