Funny Code 2013
Funny Code post from 2013.
Occasionally, I want to decode SSLSecure Socket Layer to troubleshoot an issue. This requires the server private key and is configured as follows from the Wireshark preference dialog.
The format of the RSAEncryption algorithm key list is: <server ip>, <server port>, <wireshark protocol dissector>, <private key file>. Use semicolons to delimit multiple private keys. Hovering over the edit box displays the information format. Use 'data' for the <wireshark protocol dissector>, if you don't know the for the contained protocol.
IDA PRO's Neutered Symbols
IDA PRO ships with a neutered version of the dbghelp.dll from Microsoft. The dbghelp is redistributable one from Microsoft that 3rd parties are allowed to redistributed.
As it happens this dll does not have enough intelligence to perform network or environment variable look up for symbols e.g. from _NT_SYMBOL_PATH. There is a way around this as the dbghelp.dll that ships with the Windows DDK does know how to search the _NT_SYMBOL_PATH path including network searches. The solution is to replace the IDA PRO version of dbghelp.dll with the one from the Windows DDK.
As it happens the Sysinternal Process Explorer has the same issue; however, they provide a hand gui modifying this setting so see my
sudo apt-get update |

The default MDSN Windows 8 installation requires Product Key Activation in order to setup. The following steps are useful in editing the MSDNMicrosoft Developer Network iso to enable the Skip button during the install.
1.Extract the boot.bin from the msdn iso image. Download geteltorito.pl to help extract the boot image.
./geteltorito.pl win8_image.iso > boot.bin |
---|
2. mount the win8_image iso to a folder. It is read only e.g. a DVDDigital Versatile Disk so after mounting copy the contents to a writable folder.
mkdir win8_ro mount -t auto -o loop win8_image.iso win8_ro mkdir win8 cp -r win8_ro win8 |
---|
3. Copy any modification into the win8 folder. In this case a file ei.cfg was added to win8/sources.
[EditionID] Professional [Channel] Retail [VL] 0 |
---|
4. Copy the boot.bin into the win8 boot directory. mkisofs requires the boot.bin be located in the image as a relative path is used.
mkisofs -udf -b boot/boot.bin -no-emul-boot -hide boot.bin -relaxed-filenames -joliet-long -D -o ./new_win8.iso ./win8 |
---|
5. chmod and chgrp the new_win8.iso so the linux gui can burn the dvd. Just right click.
6. The following iso is modified to enable skipping the Product Key prompt. [\\fs-01\share\OS DVDDigital Versatile Disk ISOs\Windows 8\skip activation modified]
Use windbg pseduo registers is helpful for breaking halfway through a loop. Espically, if the loop has a 100 iterations and it is not possible to modify the source code. The following command will break on the 103 call to InternetReadFile.
r $t0 = 0; bp wininet!InternetReadFile "r $t0 = $t0 + 1; j $t0 < 67 'gc';''" |

To scrape virtual memory to analyze the memory forensic characteristics. Dump strings in memory using windbg use the following command.
0:003> .dump /mf "C:\Work\testing\bc16r3x64pnr.dump" |
---|
Run Sysinternals strings on the .dump file using the following command.
C:\Work\testing>strings.exe bc16r3x64pnr.dump > bc16r3x64pnr.strings.txt |

Takes the input file, slices it into 1024 byte blocks, fills the blocks with random data, and generates a collection of files. The files that are not flagged by AVAnti-Virus must contain part of the AVAnti-Virus signature.
Take the survivor block list from slice.py, generates 4 byte blocks, fills the blocks with random data, and generates a collection of files. The files that are not flagged by AVAnti-Virus must contain part of the AVAnti-Virus signature.
The following are procedures to get WinDbg to load symbols for injected memory code. First update the symbol path to include the location of the debugging symbols.
srv*C:\WindowsSymbols*C:\Work\rdb\blackcrow\client\x64\Debug*\\ISIS\Symbols |
---|
Assuming the code has been injected into memory the following command will load debugging symbols for the dll.
.reload /f /i client_x64.dll=poi(pImageBase) |
---|
It can be helpful to turn on verbose symbol resolution using the !sym noisy command.
