what about bootkit, infect the kernel and other security questions.

Hi, I have some questions about security and computer forensics on opensbd.

- Is openbsd vulnerable to bootkit ? and firmware rootkit ?
- Can an attacker (with root) infect the kernel and insert code to be relinked ?
- Can an attacker substitute the entire kernel with an infected one ? If yes, how to check its integrity ?
- Are there forensics tools for openbsd ?
- Could be usefull memory forensics frameworks like rekall and volatility in openbsd ? Is planned to build something like that ?


Thank you.
