Earlier quoted context omitted.
What if it was a deliberate effort from Hacking Team itself to fake a breach, produce a torrent file to be downloaded and compromise whoever is downloading it? The size would need to be large enough that whoever trying to download it will have to stay a relatively long time.
The massive PR hit they're taking means their company will most likely die. And "compromising" someone merely by letting one download stuff is at best a gamble, any decent infosec professional will examine this stuff with the same precautions as when analyzing malware.
How can someone be so sure what an entity is thinking or doing? Yes, it's not likely. Yes, it's risky.. but what if they were really bold?
The PR hit is a non issue if it is the case, since they can simply say what happened: "Basically, here's how to own a huge number of very sophisticated people". Make nice slides, and show them at Black Hat or something like that. It's "research".
The icing on the cake would be to present this material to the very security researchers who've been ownd. This would be a huge PR stunt since it's basically security researchers who will download the file.. And if security researchers are as confident as most people that this simply can't be a con, then all the better :)
It is still not likely, but it would be beautiful.
PS: Something like that happened at NASA many, many, years ago. There was a security breach and instead of shutting it down, the security team uploaded a ton of bogus classified files, plans, and reports to keep the guy coming and unsuspecting. Until they got him.
