Building and running upc_keys.c on Mac OS X

Posted by jpluimers on 2016/01/27

Even after the SpeedTouch password algorithms were disclosed 2008, ISPs keep using weak algorithms to generate their default WPA/WPA2 passwords in their routers:

A short while ago, blasty published code to generate the WPA2 passwords for UPC routers. Even though Ziggo now owns UPC, a lot of  this UPC equipment is still in use. I guess it won’t be for long that similar code for Ziggo routers will be published too.

The code at is easy to download, build and run on a Mac OS X machine even when you don’t have Xcode installed (use the “xcode-select –install” trick):

gcc -O2 -o upc_keys upc_keys.c -lcrypto
./upc_keys UPC0053284 5
./upc_keys UPC0053284 24
