Are Computer Crooks Renting Out Your PC?

An anonymous reader writes "Brian Krebs recently posted an interesting piece looking at an invite-only service marketed on shadowy underground forums that lets crooks 'rent' or 'buy' access to individual botted PCs that can be used to tunnel traffic. The story looks at the mechanics of renting out bots, and the author traces some of the infected systems back to real businesses. From the post: 'The Limited; Santiam Memorial Hospital in Stayton, Ore.; Salem, Mass. based North Shore Medical Center; marketing communications firm McCann-Erickson Worldwide; and the Greater Reno-Tahoe Economic Development Authority.'"

      Windows is trivial to secure with a wealth of free services from MSFT SE to AVG to Comodo CIS to Avast.

      Wow. Do you realize that AV software is largely ineffective against new viruses? Here is a typical scenario out of my life: a friend wants me to fix a Windows PC infected with a virus. Sometimes the virus is apparently racing the AV, and sometimes the AV is disabled. But there is always AV. So what good is it? The only useful feature of an AV software is that there is a slight chance it will behave unusually after the machine is infected, and so alert a user of an intrusion sometime in the past (that is, of course, only if the virus is destructive or buggy).

      So on one hand you acknowledge that Windows is insecure by default, and should be secured. But to secure it, you want to install a piece of software that slows the computer down, while failing to prevent many viral infections.

      You also fail to address the biggest issue with securing Windows: it is theoretically impossible. Because the software is proprietary, it is insecure by any sensible definition. It is insecure for you as the user, although it is made to provide "security" for Microsoft. Not for any technical reason, but solely because of Microsoft's greed, you have a backdoor in your OS that only Microsoft (you hope) can use. Whatever other security holes there are, you propose to fix with other proprietary programs, each having its own backdoor.

      When Linux becomes a big enough target IT WILL BE PWNED.

      Linux kernel will be pwned? As in, once Linux reaches X% desktop share, all of the sudden a bunch of kernel exploits will be found? How? The value of a kernel exploit today, either local or remote, is already enormous. If they are already found at the rate they are introduced, then what does the popularity have to do with it?

      Or did you mean, Linux-based OSes will be owned? All of them at the same time? Or one in particular? And then which one? I am not surprised seeing Android in trouble: every android phone sold today is a proprietary platform, and the proprietors happen to be incompetent. This does not mean that we won't be able to install Debian or Slackware on a phone a few years from now and enjoy rock-solid security.

      After I re-trained the one guy who kept adding users into Local Admin on how to determine (regmon/filemon/procmon) which folders/files/regkeys needed additional permissions (and how to manage a local group for those settings) and he continued to do it, I was only too happy to remove his access to be able to change any security settings or add any users to any groups.
