    Maybe a lot of /. readers are too young to remember real viruses, or to have played around/collected them, but its been a decade since a real infectuous virus has gone around.

    If it can't infect any arbitrary EXE file, its not a virus, its a trojan or a worm, depending on wether or not its a moronic user or a security hole that allows it to enter the system.

      The main reason we needed to have a copy of the virus in every executable was because we were running on DOS, which doesn't usually support multiple programs running at once. And a lot of networks were little clumps of networked file systems.

      Now that the most common OS's support multiple processes at once, and the internet/web/email is the main thing that connects everybody (and writable network file systems are mainly only found in the workplace), viruses have naturally changed.

      Old schoool viruses tended to be designed to do damage. They infected as many files on the system as possible often destroying the file in the process.

      This approach is counterproductive if you want it to spread. Modern e-mail worms rarely show much evidence of their presence, if it seems like nothing is wrong then the user won't look for a problem. This leaves the worm free to mail itself to thousands of others and the system is added to the long list of compromised machines at the crackers disposal for DDoS attacks or spam relays.

      This is the same reason you don't get any 'wipe your hard drive on a certain date' viruses anymore. It isn't about doing damage it is about infecting as many machines as possible either for the 'fame' or to build up nets of infected drone machines for another purpose.

      I am surprised the article didn't mention the real reason MyDoom targeted SCO, it was a diversion. Spammers need new drone machines to send spam from but they don't want the backlash from being connected to a virus so they add in a diversion, the attack on SCO. This took the heat off the spammers and placed it firmly on the OSS community. And it worked, kind of, only recently has the spamming 'features' of MyDoom seen any press. For weeks all that was reported was how it was probably created by a OSS zealot lashing out at SCO.

    This rings all too true. If forwarding ports for certain applications wasn't such a pain in the ass, I would say make ISPs require firewalls or find a way to have some sort of personal firewall for their connection that they can access from the internet and change the settings on. Just a thought.

No amount of emergency IT sessions with the staff explaining precautionary tactics involving attachments is going to change that, and if any psychologist recruitment is necessary it's to explain why the average person keeps clicking attachments to messages in obviously broken English.

    I've also wondered about this. I suspect it is because it is extremely difficult to change an operating system that is designed with permissive security instead of restrictive security. In Mac OS 1.0 to 9.2, MS-DOS 1.0 to 6.22, and Windows 1.0 to XP anything that is not explicitly forbidden is allowed. Apple addressed operating system security by using a UNIX base to create Mac OS X. I suspect Microsoft will change from a permissive security model to a restrictive security model in Longhorn.

    I have been working as a consultant for small office and home office users since being laid of from Intel in 2002. The view from the small office and home office is very different from the view from within the IT industry. I've been working to educate my clients on the importance of regular backups, anti-viral protection and firewall protection. I spent the last two weekends removing viruses from computers that were on cable modem connections with no ant-viral software installed and no firewall installed.

    I am starting to think that I need to help my clients to protect their data and make their systems hard targets. I'd like to think that the virus problem will be addressed by operating system changes. However, the reality in the small office and home office is that operating system upgrades are almost always tied to the purchase of a new computer. Third party security products will continue to be important as long as users stick with what works for them today without worrying about what might be available tomorrow.

    But how often do you run across a computer you have to service with expired virus subscriptions? It seems to happen to me quite a bit. I suppose M$'s virus scanner mentioned earlier on /. might help, but that reeks even more of conspiracy than the current "protection money" setup does.

    Rather than bundling a questionably legal virus scanner into their next service pack, Microsoft should perhaps add a tool that helps to lock down permissions on NTFS volumes, creates unpriveleged accounts for users and various services, etc. Even with the multitude of security holes, Windows can be made a lot harder to mess with, if you put a little work into.

    I remember the days when anti-viral software was freeware or shareware. The anti-virus industry will have to adapt when Microsoft includes free anti-virus technology in Windows XP service pack 2. Assuming of course that the XP SP2 anti-virus software is robust and fully featured. Perhaps some of the anti-viral software companies will have to evolve from providing software to providing security conulting.

    Some security companies do give back to the community. GRISOFT offers a free version of AVG Anti-Virus 6.0 for single home users. Zone Labs offers a free version of the Zone Alarm firewall.

    With the professional turn in viruses, I wonder if we'll ever see an automated version of the Make Money Fast scam?

    At each hop in the infection, a virus could gather PayPal and other account information from the hard drive. That would be passed along in all the mailings it sends out to other machines, gathering more account info along the way. Once it travelled five hops, it would use the information to send five dollars to the account at the top of its list, remove top account, move the others up, repeat.

    The social engineering aspects are huge: "Gee, my computer has been infected, but if I wait until it's infected several other computers before removing it, I could make millions!" It could even come with a reassuring EULA: "This is really legal honest! The FTA said so!"

    There are privacy concerns, of course, but if it only passed on the account information required to deposit and not to withdraw money, I'm sure people would feel so much better about it. :^P
