Corporate Servers Spreading IE Virus [Updated]

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?

    Since the article is very vague, what happens is that once they compromise the IIS server, they modify each site on the server to write a document footer to every page. The document footer calls a DLL placed in the %windir%\system32 directory. The DLL writes a line of JavaScript to each page which redirects the user to a remote server to download the malicious code.

    All it has to do is read in a dictionary file, then catch the 'new page loading' event, perform morphological analysis on the page, and edit the page as it loads to include ruby tags and/or something to display definitions in the toolbar. That's it! It's fairly computationally intensive and sometimes the right html to insert at a given point is a bit of a guessing game, but it's not rocket science. But HOW THE FORK DO I DO IT IN MOZILLA??

    Basically: create an XPCOM component in C++ (if JavaScript or Python are too slow for you) which performs the computation.

    If Firefox can easily import my passwords, can't every adware and such also "import" them and send them anywhere?

    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.
