There was a small ban wave on the 23th of this month. Multiple users of DaevaTool got hit and at least two mmoninja users.
There were rumors of those two programs being detectable but I don't think they are.
Why? NcSoft usually collects bans till they send them all out at once. That is supposed to cause some panic under botters - and help NcSoft help hide their detection methods by decoupling bot test and ban feedback.
I am still using both programs and am not banned, but guess it can't be wrong to be a bit cautious.
EDIT: A bigger group of Angel Suite users got hit as well
