"wiretapping" your SSHd is one way to find out what people are up to

Also .. if you have the resources, a passive tap and another box that
has enough disk and I/O to keep up is useful to see who was doing what
right before the packetstorm happens.

If you can take the box offline and grab a disk image, tools like "fls"
from TSK can generate a filesystem timeline, again .. who touched what
right before it started...
