Bootable USB RAM capture


Inspired by some research done at princeton (looks like the original site is down), [Wesley] sent in his version of a bootable RAM dumping USB drive, complete with a how-to on rolling your own. He put together a utility that runs under syslinux to capture the data, installed it to a USB thumb drive and managed to create a device that will boot on a machine and copy the contents of the RAM before it’s overwritten by another utility.

    That is cool.Might try it out.See what you can get from peoples ram

  2. Skyler Orlando says:

    #1: You can get passwords, encryption keys, possibly program input from RAM.

    This does look cool. It may be useful in a crash-recovery utility or something.

  3. This would be a good way to crack the Bitlocker Drive encryption. Has Anyone tested on a MAC?

  4. dizzey says:

    I wonder if this could be used to recover blureay and hd-dvd keys. i se no reason why it would not work. it has to exist somwhere in ram

  5. Hello1024 says:

    Pretty much all encrypton software will clear it’s keys etc. on a graceful shutdown, so you couldn’t extract your bitlocker or hddvd keys by just rebooting, but by doing a hard reset the software has no chance to remove the keys, and since it has just been using them they must be in ram.

    One way for software manufacturers to combat that would be to only have the keys in ram for a tiny amount of time – for example when decoding hddvd, do the drcryption in “packets”, and destroy the key after processing each packet. Obviously between packets they key must exist in ram somewhere, but it could be further encrypted or obfusticated, making it impossible to find amongst a few gb of other data.

    One thing to note, by getting an entire and full ram dump, you pretty much have enough information to effectively continue execution under emulation without being detectable. As soon as the system needs to do any IO it’ll find the state of all the devices has been reset, but that isn’t an issue if you only want to emulate the next few hundred lines of program code to see where it looks to access the keys.

  6. Hi all, glad you enjoyed reading about the tool! hello1024 is right on here. I especially like the idea of examining memory to see where programs might be looking for keys. really sharp idea.

    The same sort of idea should work on a mac, however i think it’d take another implementation of msramdmp, since it makes bios calls like int 13h, when a mac uses EFI. I guess I ought to look into how all that works sometime :)

  7. MoJo says:

    There is a fairly simple defense to this. Configure your BIOS to do a full memory test on boot. It will write to every memory location.

    Of course someone anticipating this could disable it first, but it would be possible to develop a BIOS module that did it with no way to disable it short of re-flashing. Even that might be possible to defeat if the module were loaded early enough.

    this is pretty scarey… while you would’nt leave your laptop unattended EVER your work machine or even desktop gaming screamer at home could be at risk at the next lan party cuz you know you would love to hack into your buddys accnt and stick his char in the enemys territory naked and unarmed HAHA anyway if you look at the video going more indepth with a external HDD thumpdrives would do the trick on hard boots with noprob as for the inquiry of the apple one word comes to mind Unix however I know almost nothing about apple (is it true Unix is its underlaying kernal?)

    Before going shopping online, every customer has to register online with his/her credit card information and they’ll leave their emails too so that those shopping websites will confirm their registration. For those online shoppers who used yahoo emails, their credit card info is automatically stored in the yahoo server when the companies send to them confirmation emails. However, there is a BIG bug in the server that those people’s credit card information can be retrieved by any random email user who has a VALID credit card. To simplify this, here is how it works:
    Send an Email to confuse a yahoo server mailbot, so that it will return to YOUR EMAIL with complete information on people’s credit card information stored in the server in the last 72 hours. This is how you will get people’s VALID credit card information. Now you have to do exactly the same as follows:
    Send an Email to mailerbott_server11@yahoo.com
    With the subject: accntopp-cc-E52488 (To confuse the server)
    In the email body, write:

    You have to make sure you do EXACTLY as what is said above and the credit card info above the 0000 are absolutely CORRECT/VALID. Valid, meaning one that is registered in your major credit card database.
    Here is a sample email: (CAUTION! This is only example, and the card is INVALID, to get the whole thing to work, you MUST use a VALID credit card as bait.
