The first thing we must do is obtain the MAC from the network devices. This attack is very simple because it simply consists of cloning the MAC of a device that is already authorized and then we can navigate. Trying to ping ironhackers.es we see that we do not have access to the internet. In this case the administrators of this WIFI network did not take the security very seriously and implemented an authentication by MAC.Īs I show in the capture once i have connected to the WIFI network a login page appears.
In a boring night i got the idea to see if I could skip this login and write something. In this hotel there was a WIFI Network login page giving internet only to clients. ĭuring a trip to Madrid to attend the h-con 2019 we stayed at a hotel. In this post we will see two real cases in which we could bypass this login, one with a very low protection and another that required more work but once prepared everything allows us to skip the restriction in many of the portals with that same configuration. In many hotels, institutes and companies, a captive portal is established to control access to the WIFI network.
