Encoder/Decoder Shellcode 64 bit

My first attempt at using Ruby and I’m enjoying using it, so much so I replaced all Python code with Ruby in the Encoder/Decoder Shellcode blog post… 931 more words

Assignment 7#Custom Crypter

For this assignment, i have chosen to demonstrate the creation of an AES (Rijndael) shellcode crypter using the EVP cipher routines of the openSSL project which are a high level interface to certain symmetric ciphers.The reason i used AES is because of its strength against attacks. 1,677 more words

Assignment 5.3#msfpayload -p linux/x86/shell/reverse_tcp

Before moving on to the actual analysis of the staged linux/x86/shell/reverse_tcp shellcode i would like to mention that i first tried to analyze a meterpreter shellcode but i found that is almost impossible to comment and explain 1228800 bytes of shellcode that is produced by metasploit for the meterpreter stage 2 shellcode (as we can see on the following picture)and secondly and it would be silly to do so cause the code is open… 2,551 more words

Assignment 5.2# msfpayload -p linux/x86/shell_bind_tcp

In this assignment i will examine the inline payload linux/x86/shell_bind_tcp.
This inline payload contains all the code necessary to create a bind tcp shell.
Generally inline payloads take up more space than staged payloads, they are more stable and consistent because all the instructions are included in the original exploit string. 7,475 more words
