If someone says that their intent is to look for X inside of Y, I highly doubt that announcing that you did indeed find X inside of Y would be a security risk.". If it was that sensitive, why even announce that they are looking for anything inside of anything?
They’ve already announced intent and described the purpose. The enemy will 100% know what was found, the only reason for obscurity is to keep a failure from going public,as not saying anything at all is only marginally worse than what they did.
