On the Prevalence and Removal of Spyware?

oo7tushar asks: "There's a lot of spyware out there these days. As a Windows/Linux user I'm concerned about what spyware is installed on my machines and I'm very concerned about this issue when it comes to Windows. A few questions for the masses: What are the most common spying applications that are installed? How do I get rid of them without getting rid of the parent application? Have you encountered spyware on Linux?"

      Ad Aware does the following, plus more:

      * Removes registery settings belonging to Ad software.

      * Removes Ad software

      * Removes cookies from ad sites

    Spyware needs to communicate what it is spying. A personal firewall on your machine and some understanding of what your machine should be sending out to others and receiving in can be surprisingly effective in telling you about things happening on your machine. A good one lets you set up default acceptance for your normal stuff and so you see only exceptions.

      Yeah, but if you were writing a spy-ware program, would you use a non-standard port to send it out?

      I'd just send it over HTTP on port 80. Or better yet, HTTPS on 443, so no content-sniffing could be done on it. Would you be willing to stop all web browsing traffic leaving your home/site/corporation?

      The only way, then, to stop this would be to block traffic to particular sites, but if the traffic goes to microsoft.com, you're hosed 'cause you *need* to go there at least monthly to fix whatever's currently broken. :) Plus, now you need a community-contributed and -distributed blackout list (of known spyware URLs), and at that point, you might just as well be using AdAware.

      I was specifically speaking about if the maching in question with the spyware is a *inx, or *BSD machine, for the reference to ipchains, etc. But you have an excellent point. Sending spyware data out over https/443 would be the way to go. Thinking about it even further they could use any high numbered port that isn't reserved, or if this is a windows world grab a low numbered port on boot, and send data over this encrypted and the server that the spys are listening on decrypt there. This would be an waste of CPU cycles but if you are writing sypware you really don't care about who's cycles you are wasting, as long as they aren't yours.

      Your malware still won't work. The better Windows firewalls (ZoneAlarm and Tiny Personal Firewall) do an MD5 check on the executable before allowing traffic. If you patch the executable or try to access a port which is allowed to only one process, the activity will be blocked and/or logged, depending on your firewall rules.

      This is one added layer of security that an external firewall cannot have. Only client-native software can authoritatively check the process generating the network activity. External firewalls block only behaviour, not process-owners. Ideally, you want both, but for a Windows client, both ZA and TPF work well.

    I think that companies like Symantec and McAfee should include these types of programs in their Virus definitions, because after-all, they're a type of Trojan. This is the most logical way to rid the earth of these applications.

    At the very least, they should be identified to the user during a virus scan.

    Just because the user "agreed" to some insignificant and cryptic blurb in a 14-page EULA, it doesn't mean that this type of software is legitimate. I'd guess that less than 0.1% of users actually READ the EULA anyways. Some of the less legitimate ones don't even have an EULA or "spyware" clause.

    Linux spyware exists. Some scientific and engineering related software (typically closed source + proprietary) beam back substantial amounts of information. Sometimes they're rather subtle (data in checksum fields and sequence numbers in TCP packets).

    Firewalls won't do because the programs will refuse to run if they can't act as spyware. Best methods I know of is to either reverse engineer the executable and bypass the offending subroutines or spoof the server(s) the program is trying to contact.
