ATT&CKing TACACS+ to Pwn Your Network via a Pre-Auth RCE
TACACS+ is one of the ways large networks centralise administrative access to their equipment, alongside RADIUS and DIAMETER, and it is the one that tends to be chosen where per-command control matters. Instead of every router, switch, firewall and console server keeping its own local accounts, each device asks a TACACS+ server whether a login is allowed, at what privilege level, and often whether each individual command should be permitted. It is standard in enterprise,…

The Wrong First Question About AI
David Poll argues that starting with "What can AI do here?" leads to rubber-stamp human oversight, and that teams should instead begin with where people add or get value, building AI around the essential human parts of a workflow so the design survives the next model.
