This is a dysfunction. The term "attack action" is used, but never defined, in the D&D rules. It could be any of the following:
  • a standard action attack
  • a full attack action (the only option using the exact phrase)
  • an attack of opportunity (despite it being "no action")
  • a bonus attack, such as afforded by Improved Trip
