Ubuntu :: Mask/Alter Mac Address From Connections Coming Through Proxy
Nov 17, 2010I have a local proxy server running on my computer, but I want to add a twist to it. I have multiple connections going through the proxy, but what I'd like to is that all outgoing connections Mac Address' will be different from the one the connecting systems. Mask or even alter them, if possible.
Yes, I know the idea itself sounds weird, but I'm attempting a few ideas for a project I'm working and I ran in to this problem. Please note that it's impossible for me to change the MAC Address' on the systems connecting through the proxy (they're gaming consoles, to be specific.)
I'm currently running the latest version of Ubuntu.
Security :: Address Space Randomization On 2.6.28-15-generic Ubuntu 9.04 - Finding Base Address?
Sep 14, 2009Im an academic (university networks and security lecturer) studying/teaching network and operating system security, and inspired by the work of Hovav Shacham set about testing ASLR on linux. Principley I did this by performing a brute force buffer overflow attack on Fedora 10 and Ubuntu 9. I did this by writting a little concurrent server daemon which accidently on purpose didnt do bounds checking.
I then wrote a client to send it a malicious string brute forcing guessed addresses which caused a return-to-libc to the function usleep with a parameter of 16m causing a delay of 16 seconds as laid out in [URL] Once I hit the delay I new I had found the function and could calculate delta_mmap allowing me to create a standard chained ret-to-libc attack. All of that works fine. However .... To complete my understanding I am trying establish where I can find the standard base address for ubuntu 9 (and other distros) for the following, taken from Shacham:-
Quote:
[code]....
/proc/uid/maps gives me some information but not the base address ldd also gives me the randomised starting address for sections in the user address space but neither gives me the base address. Intrestingly ... when a run ldd with aslr on for over (about) 100 times and checked the start point of libc I determined that the last 3 (least significant) hex digits were always 0's and the fist 4 (most significant) where between 0xB7D7 and 0xB7F9. To me this indicated that bits 22-31 were fixed and bits 12-21 were randomized with bits 11-0 fixed. Although even that doesnt define the boundaries observed correctly.
Note: I am replicating the attack to provide signatures to detect it using IDS, and for teaching purposes. I am NOT a hacker and if needed to could reply from my .ac.uk email address as verification.
