Here comes the good news, one of our colleagues there shared this link to us: http://s4dd.yore.ma/eircom/ (Disclaimer: Stealing is bad) where in you can actually generate the WEP Key for Eircom routers that uses the default password. So we checked our apartments for any nearby eircom WIFI. It is simple to identify them as their SSID’s are prefixed by “eircom” which looks similar to “eircom-12345678”.
Since we can find these “open wifi” everywhere in Dublin, I’ve decided to write an Android application that can generate the WEP key using the last 8 digits of the eircom ssid.
This is a very simple application made up of these 3 classes:
- A SHA-1 utility class
- The key generator class
- An Activity
This class helps us generate a SHA-1 encrypted text which is required for us to generate the WEP key.
This class basically performs the magic. The actual algorithm was actually described from the link above but unfortunately, the author blog is now 404.
This is the main activity that will be displayed to the user. It has two buttons, a Generate WEP button and copy to clipboard functionality so you can just paste it into the wireless manager screen. The UI is very boring and here’s what it looks like:
