It’s still unclear exactly how U.S. authorities obtained the recording, but witness Jorge Cifuentes seemed to have a pretty good idea. He blamed the cartel’s IT guy...Cifuentes appeared to be vigilant about digital security. Prosecutors showed the jury his detailed accounting records, which included items like "cellular inhibitors" and "microphone searchers" among his expenses. "You turn it on during a meeting and there's no way anyone can tape it or send out anything," Cifuentes said, describing one of the devices...
The irony was that authorities were only able to obtain the call because the men were forced to use conventional cellphones while their secure network was down. Cifuentes called Cristián "an irresponsible person," and said the engineer screwed up by forgetting to renew the license on the software they had purchased. more
Note: This also reveals what can happen when someone with a little knowledge (Jorge Cifuentes) tries to play TSCM expert... "You turn it on during a meeting and there's no way anyone can tape it or send out anything,"
Be careful who you hire to advise you on corporate technical counterespionage.
