Storm Worm Being Reduced to a Squall 183

Rumours of financial schemes surrounding the botnet aside, PC World has an article that should lower the blood pressure of some SysAdmins. The Storm Worm botnet is apparently shrinking. A researcher out of UC San Diego who has been tracking the network has published a report indicating it is now only 10% of its former size. "Some estimates have put Storm at 50 million computers, a number that would give its controllers access to more processing power than the world's most powerful supercomputer. But Enright said that the real story is significantly less terrifying. In July, for example, he said that Storm appeared to have infected about 1.5 million PCs, about 200,000 of which were accessible at any given time. Enright guessed that a total of about 15 million PCs have been infected by Storm in the nine months it has been around, although the vast majority of those have been cleaned up and are no longer part of the Storm network."

    The researcher determined this with a spider he created to crawl the storm network. How does he know that the network is shrinking and not just being partitioned? [slashdot.org]

    Furthermore, the storm virus is known to be updatable. Is it possible it was updated to be even less obtrusive, thus escaping detection in other ways? Maybe it has gone into dormant mode, because the creator doesn't need so many computers at the moment.

    One interesting innovation of the worm, quoted from the article:

    "If you're a researcher and you hit the pages hosting the malware too much... there is an automated process that automatically launches a denial of service [attack] against you," he said. This attack, which floods the victim's computer with a deluge of Internet traffic, knocked part of the UC San Diego network offline when it first struck.

      Bzzzt! Wrong. There are many attack vectors for Storm's entry into someone's computer (one of which is indeed an OS vulnerability). AFAIK, the majority of the attack vectors rely on people downloading some bootstrapper program via their email or web browser. Nothing is going to stop this happening to a "normal" user on *NIX.

        Heh, I knew someone was going to trot out this old troll. The point is, it would be much easier to secure unix-type systems than windows-type systems. Compare Microsoft's budget to that of OpenBSD; now tell me, which is more secure?

        For it to be effective as a virus, it is going to have to install itself to startup somehow. What is going to do, add a line to my .bashrc? Add a script to /etc/rc.d? It can't do that, only root can, and I don't browse the internet as root. Nobody does.

        You may say, "it will prompt you for the password and idiot users will just type it" but you are showing your Windows bias. On windows, you get so many popup prompts that many users just ignore them and do whatever they ask. OSX has shown that it can be done differently, however. Ask any average OSX user what they would do if a downloaded attachment asked them for their root password, and they will say something to the effect of, "Freak out and delete it immmediately." It's because the warnings and prompts in OSX don't become annoying.

        Security on Windows is hard. For any vulnerability, it takes a lot more effort to fix on Windows than a similar vulnerability in a Unix system. In unix-world, fixing the OS is an option.

            This is why unix is so much easier to harden. Because of it is well-designed, there is much more flexibility when trying to think of a defense.
