Joined a startup as CTO/investor at an IVR company. Built up 4 years domain knowledge working with telephony fraud. exited a month ago as part of a $150m sale. Final anecdote. A certain attack requires the fraudster to call the target's bank and ask a few questions. For some reason in ALL of these calls there is the sound of a baby crying in the background. Our theory is that while testing the attack vector, the first time it 'worked' a baby must have been crying. The fraudsters think it works as some kind of high frequency disruption to confuse any biometric systems that are processing the call, so they play a RECORDING of a baby in the background of all subsequent calls. It reminds me of learned behaviour in animals. The pigeon stands on one leg and gets a treat. The pigeon now thinks the one legged approach is what makes the treat appear. The icing on the cake was when I got a call from a bank asking if there are any biometric systems that can detect the sound of crying babies... |

"To paraphrase Felix Dennis, 'It is like watching a millionaire point his finger at the sky, then running out to write books with titles like `How to Become A Millionaire by Pointing at the Sky`, when all along the millionaire was just trying to show people the glory of the sunset."
