      That line of defense fails when only 1 person forgets this fact (or as a permutation of the following) and the "virus/worm" spreads itself by having the from address of the newly infected person. Plus, it doesn't take a lot of effort to find out who the IT or some other higher up in a company is and use their name as the sender of the email.

    Some enterprising cracker is going to encapsulate a key logger into a piece of spyware, it is going to have a logic bomb in it so it will self destruct (the purpose to gather info and then leave no trace) , it will record passwords and other info, and that info will be sent back to some third party possibly a hostile government.

    It's going to happen. Here's why it's troublesome and mod me down if you must but our operation has a blind allegiance to Redmond and the IM folks are not particularly bright. We have had network problems in the past. China has opted to bet the farm on Linux after seeing the Windows Source Code.

    As one of the few Linux developers here, I fear a nightmare is coming. I would really welcome any ideas that anyone has about how we combat this or put our minds at ease.

    Redmond related flames go to /dev/null.
    • I second that, it would not be too hard to either write the key logger or the logic bomb - for that matter it would not nessecary need to destroy the entire program, just anything that can be used to track back to the oginator. The biggest problem in preventing something such would be to control the vectors through which it could be introduced to the network (i.e. Users running e-mail attactments), because once the program is on the network the damage has been done.
      • The advantage of completely wiping the key logger is that if you destroy the evidence that they've been hacked, they'll never raise their suspicions, and you're much more likely to get away with whatever you're going to use those passwords for.

        Otherwise some administrator browses through someone's machine two months later, trying to figure out why it's so slow, and says "oh, shit..." - and then security clamps down like a {pick useful crude metaphor here}. It's far easier to slip in when noone's the wiser.
      • I disagree...it is MUCH better to have the entire program destroyed and no trace left whatsoever that the key logger/trojan/whatever you want to call it was there. That way a post mortem could not determine whether a specific machine was compromised.

        What would be scarier to you if you were in charge of machines with valuable data on them - a warning that said there was a potential breach, and check here, here and here to see if you were affected, or a warning that said there was a potential breach, howeve

        Two years ago I was working for a major bank's international head office, and the security there was paranoidal. It was a sys-admins dream come true.

        • No FTP or telnet, only ssh allowed, and ssh server , configured to allow access only from a very restricted subdomain

        • Audit loggig of every data that goes in-out

        • A new password generated for every previleged a/c login. i.e. password valid for only one login

        How about delaying the delivery of suspicious attachents by half an hour? If you get 10 emails (not necessarily the same addressee) with the same attachment within half an hour then declare it a virus/worm and do not deliver it. If no other copy arrives within half an hour then it is likely to be safe to deliver.

        So just replace the attachment with a message stating that the attachment will be delivered in half an hour. If you get a call from the CEO then you'll know that the attachment was legit and you ca

        This also leads to another point, if you do security well and nothing happens, then no one knows, but you end up pissing every one off. If you do not do it right, no one is pissed until something happens, then everyone knows.

      Why do the corporate firewalls not block out-bound traffic to all ports but a select few HTTP/SSL etc?
      I think any decent sized corporation with a firewall admin does this already. The problem starts when you have protocols designed to circumvent firewall security. SOAP is nothing really but rpc over http on port 80. You can block whatever ports you want but as long as you have an outbound port opening somebody can find a way to use it.

      What kind of idiot sys-admin would allow the corporate users , to run their PCs with admin previleges , so that any unwanted junk s/w be installed on their PCs ?

      Again it doesn't really matter. All the buffer overflow exploits that have happened recently didn't make a check to a security manager to see if they could install a piece of software. Nimda, code red etc just installed themselves.

      What kind of stupid sys-admin allows .vbs, .js , .exe, .sws attachements thru the corporate email ?
      If you haven't seen the list of attachments outlook 2003 won't let you send you'll laugh your ass off when you do. Its basically any document that you can create with a Microsoft tool with a few of their competitors thrown in for good measure(pdf!?). I still think people will find ways to socially engineer their way around that one.

      Doesn't really matter. If the pc of someone who is authorized to view that data is comprimised the cracker gets the keys to the kingdom.

      If there are programs that you run normally, and you know the whole list, you could write a little daemon to keep track of the process list. If something else starts running, have it alert you.

    There's an article in Dvorak's column in this month's PC Magazine (near the middle) [pcmag.com] describing how a day trader used a key logger to steal someone's brokerage password via a similar scheme. From the article:
    Using an alias, Dinh began prowling around in an online stock-chat forum, until he got the e-mail addresses of some of the traders. Using yet another alias, he then e-mailed these folks the key-logging backdoor, claiming in a long letter that he was beta-testing a new stock-charting software system and wondering whether they could help.

    Apparently, one unsuspecting sucker executed the software and wasn't suspicious when it didn't really do anything. Now Dinh had a backdoor and simply key-logged until he found the guy's online brokerage information and password. He could buy and sell from the guy's account.

    Apparently he used the other account as a dump for derivatives that he needed to offload quickly. Of course the person in the story should obviously have been more careful about clicking on attachments, but one lesson here is that as people become increasingly wired, the value of logins and passwords is becoming high enough that stealing those is as valuable or more than credit card numbers. This is especially true if you think about how much you can do financially online -- many people use the Internet almost exclusively for bill payments, stock transactions, money transfers, etc.

    The problem here is at several different levels. You can no longer expect nowadays to be protected by simply closing your doors to the outside world (ie. protecting your computer against outside attacks), but you also have to learn how to protect your computer from internal attacks. The risk of having a program already installed in your computer trying to access your data is quite higher these days than it was a few years ago, and for this very reason corporations should spend more time trying to develop encrypted systems for data storage and tighter policies aimed at improving their security systems.

    It's also necessary to protect your data against your very own employees when they are not supposed to be able to see it. And I can say that often this is not the case.

    Another important and necessary step is to instruct people using computers to work on security. And this is often not the case either.

    As a sysadmin that has been dealing with security issues in financial and other corporate settings for well over a decade, I can tell you that the fear-factor on kiddies with their viruses starts to fade over time. However, what I've noticed happening is that people are coming to accept these relatively benign viruses, root-kits, etc as a fact of life, and they seem to be forgetting that where kiddie-hack-of-the-week can succede there WILL ALWAYS BE a small, but worrisome number of clueful people exploiting the opening.

    Most often those people are insiders, so you have the added worry that things like firewalls are useless (do you sniff email for viruses on internal mail? do you have unpatched servers that only intenal users have access to?), and they may be able to convince others that you think you can trust to look the other way.

    Security is one of those ugly balancing acts. Ultimately, it's a losing game because once a determined cracker with a clue sets their sights on you, you're done for. No amount of security is sufficient... really (yes, even a gasketted vault with armed guards CAN be cracked). The key is risk-vs-reward and always trying to make sure that some poor clueless bastard out there is an easier target than you.

    So here's a (marginally) related thought.

    Vendors routinely give out free stuff at conferences, and one of the popular ones these days (actually halfway useful!) is a free 32mb USB key. And of course, every such key comes with plug-n-pray drivers so you can plug it in and start writing to it.

    They could easily include some network code in the driver that sends every document you write on the key to the company that sold the device. Of course, obscure this process: send only during idle periods; encrypt the document; send the files to some anonymous file dump in Malaysia or something that's only known and accessible by the company...

    Since these devices are routinely given freely to corporate representatives, this might net a high percentage of corporate documents, some of which might be valuable.

    - David Stein

    • In this case, my counter would be that you know the vendor... or at least, you should know the vendor and at least trust them somewhat. If "unknown company X" gives me something with a burned disc or whatever I'm going to be a bit suspicious. If well-known/respected company Y gives it to me, I'm a bit more trusting.

      The main differential is that virus writers are in many ways untracable and anonymous. Most of the people presenting at a conference should be traceable in some form, and thus accountable.
    • There's a standard USB Storage interface, and every modern OS (i.e. everyone but SCO) comes with its own drivers for treating devices which use that interface like removable drives. There's no obvious reason for a USB storage device vendor to produce their own drivers (which would require installation, whereas the OS drivers should just work when you plug the device in); if you've actually seen one with custom drivers maybe you really should be suspicious.

  • to the MS Outlook virus-propagation problem.

    It's simple - create an Outlook virus which emails a Windows activation-code cracking program to everyone in the victim's address book. Then the virus would redirect the user to the warez sites where they could download "free" copies of Windows.

    I can just about guarantee that Microsoft would have a patch within days, if not hours. After that, auto-execute for email attachments would be a thing of the past.

  • They should be writing definition files that detect and remove all spyware. Turn it on by default and make it optional to remove. In my opinion they are a much larger threat than viruses. Essentially, they're legal trojans.

    Of course many AV companies are scared to do this becuase of ligitation, but a line has to be drawn somewhere. Not to mention the AV program itself might be spyware if it sends data home about the user. Even "anonymous" data should be considered spyware.
