What do you do if you have to examine an Android mobile device which has a pattern lock enabled?

Pattern locks are a security feature used by Android devices as an alternative to a password or passcode which stops unauthorised users gaining access. However, this causes problems when it comes to analysing the data stored therein.

CCLs’ researchers have developed a novel technique to retrieve the lock pattern, enabling digital forensic investigators to access and examine such devices.

The analysts wrote a simple script in the Python programming language which reads the data contained in the file and recovers the correct unlock pattern.

The technique has been used a number of times with great success, so the research and development team is happy to make the scripts public for research purposes.
