Ayer volví de Madrid, donde se celebró este fin de semana el Interqué. Como ya comenté anteriormente, fui gracias a una promoción mediante la cual ALSA ofertaba un viaje de ida y vuelta de manera gratuita a los asistentes del evento. Bien por la organización de Interqué y bien también por ALSA, que han marcado la direferencia con respecto a otros eventos como el EBE en cuanto a materia de transporte.
The ALSA Supra class have a Wi-Fi connection and on the outward journey it worked “more or less” correctly despite the fact that there were continuous disconnections (for navigation, almost to spare). However, on the return trip the Wi-Fi did not work properly, there was no connection and we could not navigate, so we asked the flight attendant if it would be possible to restart the router to see if the problem would be solved, but she kindly replied that it was impossible because the router was down and we would have to turn off the bus.
I am not any type of hacker, cracker or anything like that. My knowledge of breaking system security is nil beyond being able to discover (not decipher) an obvious password, but I remembered that a long time ago I had read on a university classmate’s page (Carballude, which is a crack, by the way) that he had managed to enter the system somehow.
And indeed entering the ALSA router administration system is the simplest thing in the world: just connect via telnet to the gateway, that is, to the router, and enter a username and password. You might think that this data could be difficult to discern. The balls. They are the first combination we would try to hack into someone’s router.
Once inside we will find a command line in which we can enter… commands, although it will be “caged” and will not allow us to do anything important on the router except obtain unimportant information. Solution? Well, ask for help with “?”, no more, no less, which will show us all the available commands with their description, among which is a particularly striking one called “enable”, which grants us administrative privileges over the system.
Once from there, you can enter more sophisticated commands that allow you to configure the router (DNS, modem, time zone, etc.) and also reboot and reset it. If we were sons of bitches, we could also change the router configuration to divert traffic to our computer and sniff all the data on the network to obtain the information that was transmitted to the other computers on the bus, but surely that is something that no one will ever do… until they do it and complaints start pouring in.
PDTA: Despite all this nonsense, I couldn’t get the Internet to work :(
