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

list | List all processes currently available on the system |
