Corporate Servers Spreading IE Virus [Updated] 1028
uncadonna writes "ZDNet is reporting that corporate web servers are infecting visitors' PCs. The combination of two unpatched IE security holes and hacked corporate websites is apparently distributing malware via
several high-credibility sites. ZDNet says users have 'few options' other than alternative browsers or platforms." Update: 06/25 14:50 GMT by J : A reader points out Microsoft's What You Should Know page. Here's the short version for avoiding this Critical severity attack: you must install add-on software, and change multiple settings in multiple programs, thus causing "some Web sites to work improperly." By changing more settings, you can regain functionality for a particular site if "you trust that it is safe to use," which you have no way of knowing. Or try Firefox. Update: 06/25 19:30 GMT by J : Reuters reports the attack installs a keysniffer which can steal credit card numbers, passwords, and so on. The story offers safety tips, but fails to mention that, after patching the hole, many users will be infected without their knowledge. Shouldn't the "fix" include ceasing to type anything important into your computer until you purchase software which can detect and remove the Trojan? And will you be downloading that software with Mastercard or Visa?

Here is my postulate: The only way you can trust any software is through independent audit of the source code.
Whether that's you yourself, or somebody to whom you have paid a sum of money. Relying on what the software supplier -- or their hired goons -- have said, is asking for trouble. Somewhere in between the two extremes, lies a third option: just let enough ordinary people, independent of yourself and the author, look at the source code -- and cling with all your might to the assumption that if anybody spots something nasty, then they will speak out, just because they have no good reason not to.
If anyone knows another way that software can be made trustworthy, beside independent source audit, please feel free to enlighten me. Until such a time, I stand by my assertion that open source software is more likely to be trustworthy than closed source, varying with the validity of the aformentioned Great Assumption.

2. Don't install the latest security patches for I.E. 6.0.
The article mentions that the exploit takes advantage of the recently announced vulnerability in I.E. that an advertising company was exploiting. My testing of this vulnerability revealed that it would be unsuccessful if you didn't use a priviledged account. And oddly, at least with the previous exploit, the code wouldn't run until I installed the latest security updates. A generic install of Windows XP or one with SP1 didn't appear to work. Odd.

3. Switch to the Security tab, and move Internet into "high". This will disable most forms of scripting. However, It also disables the Windows Update site.

Basically: create an XPCOM component in C++ (if JavaScript or Python are too slow for you) which performs the computation. Mark your XPCOM interface as scriptable, use the typelib compiler to expose it to javascript then pass in the browser DOM so it can be edited by your component. Then write an extension to catch "page loaded" and pass the DOM to the loaded XPCOM component. I think that should work.

I would think so.
Here is the question to ask yourself. Does the program that stores your passwords require any input from you to retrieve them (such as a master password). If so, you may or may not be safe - depending on how the master password is implemented. If not, you are definitely NOT safe. The passwords may be encrypted, but the key is somewhere on the hard drive otherwise IE couldn't make use of them.
If there is a master password then it could be used to encrypt your password database, which would probably make it fairly safe if the crypto isn't broken. Then again, it could just be stored as a hash on the disk and the passwords could be stored in the clear.
Bottom line - if the computer doesn't need to ask you for a password to access data, then spyware potentially doesn't either. Sure, things like sandboxes can protect some data from malicious apps, but they generally aren't perfect. Strictly speaking, neither is a passphrase since it doesn't have all that much entropy.
If you really want to be secure, store your passwords encrypted using strong crypto, and store the key on a smartcard protected by a PIN. To defeat that requires the smartcard at the very least, and unless you can hack the hardware it requires the PIN as well. Most decent smartcards will delete their keys making them useless after so many failed PIN attempts.
If iButton support was a little more mature on linux I'd probably start using it. You should check out their Java ibuttons - sounds like a neat solution for these kinds of problems. And they're pretty cheap.
