TLDR; Default admin login on WEP encrypted WLAN router for getting free stuff at my hair stylist studio.

Free WLAN in my hair stylist studio: They had their WEP key laying around in the waiting area. Well, I am not very happy with WEP, thought that they never heard of security. Found the default GW address, typed it into my browser and pressed Enter, logged in with admin/1234 and voila, I was root on their ADSL router 😌 Even more annoyed now from such stupidity I decided to tell the manager. All I told him was: You use a default login on your router, you give the WiFi password for free, WEP is very very insecure and can be hacked in seconds, and do you know what criminals will do with your internet access? He really was shocked about that last question, blank horror, got very pale in just one sec. I felt a little bit sorry for my harsh statement, but I think he got the point 😉 Next problem was: he had no clue how to do a proper configuration (he even didn't knew the used ISP username or such things). Telled me that 'his brother' has installed it, and that he will call him as soon as possible. Told him about everything he should reconfigure now, and saw him writing down the stuff on a little post-it.

Well, he then asked me what he can pay me? Told him that I don't want anything, because I would be happy when he changes the security settings and that is pay enough. He still insisted for giving me something, so I agreed on one of a very good and expensive hairwax. Didn't used it once 😁

Some weeks later when I was coming back for another hair cut: Free WLAN, logged in with admin/1234, got access and repeated all I did the last time once more 😎

HOW CAN YOU NOT LEARN FROM FAILS??
