Kali Linux Tutorials

Dismember is a command-line toolkit for Linux that can be used to scan the memory of all processes (or particular ones) for common secrets and custom regular expressions, among other things.

It will eventually become a full /proc toolkit.

Using the grep command, it can match a regular expression across all memory for all (accessible) processes. This could be used to find sensitive data in memory, identify a process by something included in its memory, or to interrogate a processes’ memory for interesting information.

There are many built-in patterns included via the scan command, which effectively works as a secret scanner against the memory on your machine.

Dismember can be used to search memory of all processes it has access to, so running it as root is the most effective method.

Commands are also included to list processes, explore process status and related information, draw process trees, and more…

Main Commands

Command	Description
grep	Search process memory for a given string or regex
scan	Search process memory for a set of predefined secret patterns

Utility Commands

Command	Description
files	Show a list of files being accessed by a process
find	Find a PID given a process name. If multiple processes match, the first one is returned.
info	Show information about a process
kernel	Show information about the kernel
kill	Kill a process (or processes) using SIGKILL
list	List all processes currently available on the system
resume	Resume a suspended process using SIGCONT
suspend	Suspend a process using SIGSTOP (use ‘dismember resume’ to leave suspension)
tree	Show a tree diagram of a process and all children (defaults to PID 1).

Installation

Grab a binary from the latest release and add it to your path.

Usage Examples

Search for a pattern in a process by PID

# search memory owned by process 1234
dismember grep -p 1234 'the password is .*'

Search for a pattern in a process by name

# search memory owned by processes named "nginx" for a login form submission
dismember grep -n nginx 'username=liamg&password=.*'

Search for a pattern across all processes

# find a github api token across all processes
dismember grep 'gh[pousr]_[0-9a-zA-Z]{36}'

Search for secrets in memory across all processes

# search all accessible memory for common secrets
dismember scan
