Link to the Chaos Computer Club's article (in English) about the hack is http://www.ccc.de/en/updates/2013/ccc-breaks-apple-touchid
Their article links to earlier one about making fake fingerprints http://dasalte.ccc.de/biometrie/fingerabdruck_kopieren?language=en
I would like to see more detail about how many failed attempts they had, because it is supposed to require passcode after 5 failed attempts, phone restart, or 48 hours without unlocking.
Passcode is also required to setup/enable or edit fingerprint reader.
