Ha ha this is the type of thing I deal with all the time at work. CHANGE THE PASSWORD and don't use a dumb password! In our case, that means don't use your call sign, among other things. On Sun, Aug 5, 2018 at 4:41 PM, Ruben ON3RVH <on3rvh(a)on3rvh.be> wrote:

Probably true, that is in my case the proof that changing password is needed in ALL case, and NOT using the same password for routers AND servers cause if the can break the routeur password and you use the ssame password for a serveur behind that routeur you just gave them a way to wreck havoc to everything you have.. Password are keys, would you use the same key for your house, car, bank account, business, boose cabinet and your mistress Chastity belt?? I would not especialy the 2 last one, cause one day if I get to much stuff from the boose cabinet, I dont want to use my car key on the wrong lock and unlock my mistress belt while I am not in shape enough to use it. Same for the car... ________________________________ De : 44Net <44net-bounces+petem001=hotmail.com(a)mailman.ampr.org> de la part de Ruben ON3RVH <on3rvh(a)on3rvh.be> Envoyé : 6 août 2018 11:47 À : AMPRNet working group Objet : Re: [44net] network equipment passwords Changing the password won’t do a thing with the latest mikrotik exploits as they circumvented the password and downloaded the password database Ruben - ON3RVH > On 6 Aug 2018, at 16:43, Robert Keyes <robertwkeyes(a)gmail.com> wrote: > > Ha ha this is the type of thing I deal with all the time at work.
