Magic Lantern uses keylogging to extract keys typed in, and sends them off to the FBI. This is similar to a story reported on previously, but taken one step further, allowing computers to be compromised remotely."

[+] Your Rights Online: FBI Remotely Installs Spyware to Trace Bomb Threat 325 comments
cnet-declan writes "There have been rumors for years about the FBI remotely installing spyware via e-mail or by exploiting an operating system vulnerability from afar — and now there's confirmation. Last month, the FBI obtained a federal court order to remotely install spyware called CIPAV (Computer and Internet Protocol Address Verifier) to find out who was behind a MySpace account linked to bomb threats sent to a high school near Olympia, Wash. News.com has posted a PDF of the FBI affidavit, which makes for interesting reading, and a summary of the CIPAV results that the FBI submitted to a magistrate judge. It seems as though CIPAV was installed via e-mail, as an article back in 2004 hinted was the case. In addition to reporting the computer's IP address, MAC address, and registry information, it also gave the FBI updates on which IP addresses the user(s) visited. But how did the FBI get the spyware activated and past anti-virus defenses? Two obvious ways are for the Feds to find and exploit their own operating system backdoors, or to compromise security vendors..."

      Go HoneyPot on their asses. Set up a bunch up of machines all over the place to get compromised, and have firewall software monitoring the destination of the nasty outgoing packets. From there, use a P2P model to distribute the destinations of such data, and D-E-N-Y the living hell out of their servers. For added flair, you could always include repetitious, highly profane strings in your denial actions (use your imagination).

      I would especially advocate this concept for all technies living in various foreign nations whose citizens might get "bugged" by the our wonderful boys in blue. Yes, I am openly advocating retaliatory strikes against this sort of disgusting behavior.

        IF they do eventually make it illegal to block the virus then 'terrorist virus writers' can be guaranteed a hole in every system.

        I doubt it would happen that way. Chances are, the "virus" wouldn't be self-replicating, at least the government's version wouldn't. If it were, there'd be no effective way to control it. So, if the only people who are sent this thing are people the feds want to bug, the AV companies most likely wouldn't see it.

        However, all this goes out the window if someone gets hold of this thing somehow and modifies it. They could do several things. First, they could attempt to decompile it and then post the source for all to see. If they wanted to get more, um, creative, they could modify it so it becomes a truly self-replicating virus. Not only would this turn the thing loose on the Net at large, it'd also have the possible effect of taking out whatever computer the original virus was supposed to "phone home" to. How long could a machine set up to handle data from several thousand of these things last when it's getting bombarded with data from a few million? Finally, there's the possibility that it could be modified to seek out and attack computers owned by the government. Once it got in, it would sit there and spy on whoever was using that machine. Results could be sent anywhere. Protecting all those government computers would be a massive undertaking. Even if the feds had custom software to do it, distributing it in any meaningful way to locations around the country would almost guarantee that it'd leak out within a few days. But the truth is that federal computers are running the same software that everyone else is, and the people using them can be just as easily deceived as the average home user. All it'll take is for one programmer with talent, a chip on his shoulder, a good deal of free time, and access to the right tools to decide to fight code with code. If he gets hold of the feds' virus, he could use that. If not, well, he'd most likely roll his own.

        This is a superbly stupid idea the feds are pursuing. If they write crappy code, only the truly moronic will allow this to get installed. If they write a really sophisticated piece of software, they could very well end up creating a monster that will turn around and bite them in the ass.

    How does the government expect to work around this one? There are so many things that can go wrong...

    1. Probably OS-dependent. Remember: virii for one platform (i.e., Win) will probably not work for others. That was not hard to get around

    2. Human link involved. This virus will presumably be propagated via email, or some other form of trojan. Those who tend to use encryption tend to block this type of thing from happening to their machine anyway. Yet another reason not to open email/attachments from an addresser named "CIA" :P. That was easy to get around.

    3. Network link involved. Those who use encryption are usually savvy enough to detect extra packets flying from their machine to some unknown address, which would easily be identified in a reverse-lookup.

    I'm sure trojans must have been used for keylogging before. But won't using this mean getting a wiretap order? I also don't know how this system will cross jurisdictions: can the FBI infect a user in another country to get secrets? Sounds like spying to me, and it would ensure countermeasures from other governments and a change in computing systems to defeat the virus.

    I'm hoping that some antivirus company makes a scanning system to detect this 'virus' and eliminate it. Otherwise its a change to a more secure OS, or using GNUpg (they did only mention it working on PGP, didn't they?) could do the trick.

    No matter what they do they can't get at a non-networked box unless they physicaly break in and hack it and then again to retrieve the data (or transmit via radio waves). As for the networked box it never sees anything but cyphertext, no passphrases are used, and anything it puts on the floppy doesn't matter cause even if it gets on the sandbox it can't get anywhere.

    Oh sure they could get tricky, do things with floppy boot sector virii that will run in the sandbox, log and save to the floppy, then re-run once it detects a network connection, but to this non-programmer that seems 1) problematic and 2) pretty easy to avoid. maybe even use CD-R or CD-RW.

    Few firms have virus-busting firewalls or antivirus packages which can handle new attacks before they cause damage or hide in archived material. Perhaps the scariest thing is that if a new variant is created for a specific "sting", it could quickly take over many computers over a large geographical area (consider Code Red graphs) before antivirus manufacturers or the public at large come up with a patch. In the past there has been a chance at getting a patch before infection.

    But with the public funding a combination of email hole, pc based server, network scanner, key logger, and encryption program defeater, it seems that we are *very* quickly going to enter a much more dangerous situation than ever before.

    It is not possible that this technology will never be misused by the government.

    It is not possible that this technology will remain in the hands of the FBI.

    It is not possible that this will not accelerate worldwide efforts to provide more and more dangerous security-breaking software/services.

    Because it is so cheap to develop this kind of a weapon, it is my opinion that it is 100% likely that terrorists, multinationals, and national security organizations around the world *will* coopt this technology or will develop something identical to it (or more powerful) on their own. This is the part that scares me. No more Net! Who will ever install a binary from a public server? Who will ever trust interactive content and the plugins which it requires? Who will be trusted to hold the keys?

    The FBI is moving a physical wiretap capability highly limited by timing and resources, into a software wiretap regime of high speed, exponential viral growth, widespread destablization of security prior to a court order, and extremely low cost of deployment.

    This attempt to coopt the entire networked computing base as a wiretap infrastructure is the most dangerous force I can identify to the world economy and spread of the Internet in all facets of life. It is very hard to have reasonable security for most people at broadband speeds, but one could be forgiven for hoping that problems would be solved in time. Not when the crackers' growth metric takes off exponentially and leaves pro-security forces behind.

    I don't think I'd mind if this was used against the people who have attacked the U.S. In fact I'd be surprised if something more powerful wasn't used already. But now we are going to start getting a trickle-down of progressively military weaponry operating silently in our homes.

    The cat is out of the bag.. and the technology obviously already exists. The only choice we have is to promote some kind of open source, open science project which could have some hope of markedly improving security in general, could dampen the effects of for example thousands of concurrent Magic Lantern - style attacks from every part of the world. To me, an open, international project is the only way to protect computing in the future.

    The FBI already has plenty of tools, and there is no reason it can't improve its cyber attack capability without building such a dangerous system. I certainly don't want to protect the mafia. But unless proven otherwise I think we have to assume that things will get worse all around before they get better.

    If you want to see a simulation of the "gray goo" doomsday of nanotechnolgy, simply wait a few months for the next wave of network pathogens.

    We will not be safe until we have the U.S. and other governments on the side of the public, with a law against cyber-germ warfare and a well-funded infrastructure to combat cyber-pathogens which do appear with some kind of human and computer based immune system before we enter the age of the network-borne pandemic.

      Remember Ken Thompson's hack! You only get the bonus points if you compiled the OS (and CD-ROM burning software) from source on a compiler you wrote yourself ;-)

      The FBI is evil, but not stupid. If they did it the best way possible, then their software probably replaces a key part of your operating system's networking code, so that even if you knew each and every process running and exactly what it does, you could still have their software installed and never have any way of knowing.

      After all, it's doubtful that Microsoft would object to the FBI looking at their source code for such a project, it's doubtful that Apple would object--but even if they did, the lower levels of OS X are open-source Darwin--and of course Linux is open-source anyway. It doesn't seem too difficult for them to do.

      It seems that if they were to do it the simpler way, it would be too easy to detect. If they installed it like a simple trojan, it would be trivial to detect, particularly by software such as ZoneAlarm and equivalents which monitor all attempts by programs to access the net. In fact, if it is what they used in the Scarfo case and they are using it now, if it were a simple trojan it would probably have been reported by now. People with something to hide know what software to use to protect them from such things.

      For example, "Dr. Who's Encryption and Security FAQ" http://www.slack.net/~hermit/ebook/documents/secur ity.html is standard reading in newsgroups and on websites dedicated to privacy. It is also standard reading in newsgroups and message boards where child pornography is posted. It is probably also known to organized crime and other elements which engage in illicit activities and use computers. It explains in language most people can understand, the use of PGP, firewalls, various encryption and security software, and the threat of keyloggers and trojans and how to use software like ZoneAlarm to secure network access to only those programs you choose to authorize.

      Call me crazy, but I think the FBI would take note of this readily available information and come up with a way to counteract it. Writing their trojan into your operating system itself seems like a damn good way to do this. Windows and Mac users and even Linux users expect certain processes to access the network, so why not exploit that to camouflage an "ultimate trojan"?

      There would be only one way to counteract it, and this is mentioned in Dr. Who's FAQ: make detached PGP signatures for each important file in your OS that you'd expect not to change, and use a script to check them against the files each time you boot, or each time you choose to run it. If a file has changed, you know something is wrong.

      Of course, this is very cumbersome--how many files exactly should you sign? Very tedious. I got to thinking on this some time back, and came to the conclusion that if you want the best possible security against unauthorized changes to your system, the best way might be to install your whole OS and all your apps, configure everything how you like, and immediately transfer the whole system to one file. Then, strip down your OS to the very minimal parts needed to boot and to check the signature on the "big file" and your stripped-down OS files, then decompress/mount then boot the whole OS in your "container" file. If you have lots of cheap RAM, you can decompress the file containing your OS into a RAMdisk to save some time and make the files less persistent. A lengthy process, depending on how big your OS/apps are, but if you want security there will be a price. This way, every file on your system is uncorruptable, untouchable by trojans and FBI spyware.

      I experimented with just that using Windows 98SE, and though I don't know exactly how you'd do it with Linux or WinNT/2k/XP it is definitely doable with Win9x. First I installed Windows and all my apps, then made a Zip file (using no compression at all, for speed of unzipping at boot) of the whole system. Then I deleted the system except for minimal DOS command files and a RAM disk creation tool called xmsdsk.exe and a command-line unzip tool, altered Autoexec.bat to call xmsdsk with the parameters to make a 1GB RAM disk (there were 1.5gigs on the machine), called the unzip tool to unzip the file to the RAM disk, and had the config files boot Win98 from that drive. It took fiddling a bit, but finally I got it right and it worked. When my Win98 booted, in the startup folder was a shortcut to check the PGP signatures of all the startup files and the Big File that the system was stored in.

      Not ideal. Quite slow to boot up. You can see why I don't actually still do this; it was more or less an experiment. But it did work. When the system was shut down, the RAM disk went away, and so any changes at all to the system would be undone. If the Big File the system came from, or any of the boot files, were modified it would show up the next time I booted when the signatures were checked. It was unweildy, but it did provide full protection of a sort I can't think how to have otherwise.

      So, does anyone else have crazy ideas on how to provide security against such intrusions? Preferably ones that don't require a boot time long enough that you can go make breakfast in the intervening minutes.
