We experimentally review an off-the-shelf commercial quantum key distribution system (QKD) from ID Quantique to identify loopholes and exploit vulnerabilities by simulating and performing attacks on it. In particular, we devise faked-state attacks against the avalanche photo diode (APD) based detectors of this QKD system. We have shown several successful proof-of-principle attacks through experiments and simulations.
