A lot of people asked me the last couple of days how I was able to so quickly get the information from the NetScaler attacks. The answer is that I built my own MCP server for it. I took many hours this weekend to scrub, optimize, and update it for the community.
It talks to the appliance over NITRO, plus a locked-down SSH path for nsconmsg counters and core dumps.
I leaned on it hard during the CVE this weekend. Used it to piece together what actually happened, write and verify the v2 responder policy (including checking it was bound on every Gateway and auth vserver), and dig through the nsaaad core dump. Saved me a lot of hours.
It's read-only by default. The NetScaler accounts you give it decide what it can do, so your helpdesk gets a read account and your admins get the write and forensic tools. Tested on 13.1.
