Don't forget admin:ztonpk and admin:tzlkisonpk for Telekom Serbia's ADSL, VDSL modems and IPTV/OTT STBs. 7.9 million of these devices are unsecured, it takes just one wrong step to misconfigure it to allow access to itself and you're gone. I used to port scan the Telekom network looking for modems with Port 80 open, login and reset to factory defaults, which would require a technician to come to the premises and manually re-enter the authentication settings for xDSL.
