Do you need to worry about the new /dev/mem rootkit problem?

Filed under
Security

A new paper was presented in late March about using /dev/mem to inject and hide a rootkit (PDF), and the method has been getting some press, leading to a little concern. The first thing that you should understand is that this class of attack has been used before. We know how to protect against it.

If you read the paper, you'll find out two things:

1. We need a way to write to /dev/mem as a regular user, and
2. There's a kernel config which protects against this mechanism.

    This tells the story of how I finally managed a successful transfer of email data from KMail version 1.13.6 to version 4.11.5. It is a non-technical essay exploring the obstacles I encountered, my options, and the methods I used to achieve my aim. It was written partly to give the information, but also with the hope that readers will both enjoy and be amused by the story of the "battle of KMail" that was ultimately won against "incredible odds". Links to the earlier articles discussing problems with KMail 4x are given at the end.
  • [GSoC] Kdev-Embedded, Debugging and programming embedded systems
    The actual embedded system word depends on closed-source IDEs and libraries, with high monetary value and deprecated functionalities. Programmers that would like to use ARM based boards without paying for an IDE will have problems setting up such development ambient and synchronized toolkits. The main idea of this project is to provide a plugin integrated with KDevelop to help the debugging and programming process of embedded systems like AVR, ARM and x86 based boards.
