Shellcode Tips


Shellcode generator + polymorphic encoder



Been around longer than Shellter. Has some cool powershell scripts (veil-Powerview) for AD enumeration.



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


Flare-On - Challenge 4


Hello all, and welcome to challenge number four of seven. We’re halfway through this and so far it has been alright, there was nothing out of the ordinary. 3,739 more words


Assignment 6#Polymorphic

The 6th assignment is to take up 3 shellcodes from Shell-¬≠Storm and create polymorphic versions of them to beat pattern matching. The polymorphic versions cannot be larger 150%¬† of the existing shellcode… 3,490 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
