Opening the First Generation Mul-T-Lock Cliq with Vibration

Via -

I have been looking forward to the HAR conference for a long time. After all, it was going to be the moment to publicly talk about our discovery on bypassing the electronic locking part on the first generation Mul-T-Lock Cliq. More then one year ago we discovered the samples we had in some instances could be opened with the so called ‘magnetic ring’ (you still needed to have the correct mechanical key or bypass the mechanical part). An important discovery as the attack would not show up in the electronic logfile in the lock. And the integrity of the logfile is a key issue in these kind of systems. So we immediately informed Mul-T-Lock about this problem. And even though communication did not always go smooth we came to an agreement. We agreed to go into full detail about this at the HAR conference in 2009. And that is what we just did. At the presentation we showed the problem was not magnetism … it was vibration!
