I'm gonna call bull shit on this one.

Not because Whatsapp isn't compromised (it is)

Not because it is beyond Israel's capabilities (it's not)

But because they're telling us this. No intelligence service in the world reveals their methods especially when it can be re-used on future targets.

They're telling everyone this because they want Iran to stop looking. Looking for what? Most likely a human intelligence asset inside their government. They're telling the world this to protect this source. This is why this information was leaked to a Lebanese journalist so quickly.

Iran's government is Mossad's number one priority for infiltration. Inconceivable they don't have sources on the inside.

Remember when Iranian President's helicopter crashed. Yeah, that was strange wasn't it.
