For several days now, the echoes of the loud prank on President Duda, who instead of President Macron, talked to Russian pranksters – Vladimir Kuznetsov (Vovan) and Alexei Stoljarov (Lexus) – have not been silent.
As part of our current research and development activity, we biometrically analyzed the recordings of the pranksters’ voices and compared them with the voice of the real Macron (Polish and English versions). We downloaded all voice samples in the form of individual recordings from the public domain on YouTube. Our goal was to confirm the effectiveness of biometric systems for this specific situation – identifying fraud.
What did the BiometrIQ analysis show? It turned out that the voice of one of the “Lexus” pranksters was just over 50% consistent with the voice of the President of France and as much as 97% consistent with the voice of the false president. The voice of the second one – “Vovana” – showed no similarities (0%) to the fake president.
This clearly proves that thanks to biometric analysis we managed to:
=> detect the fact, only after 1 minute, that a fake president was involved in the conversation
=> identify the identity of the fictional president (Lexus)
=> confirm that the public domain is a very good source of voice samples, which may not always be used for noble purposes
=> strengthen the thesis that attacks using social engineering are the most effective, and in this case it was the choice of the right time when we are dealing with increased stress (rocket drop).
