If there is one security technique that has proven to be as effective and realistic as keeping diamonds safe in a paper bag it is security through obscurity.

The idea of security through obscurity is an old one: In the desk there’s the hidden compartment for the property deeds. Or there’s the secret door that looks like a bookcase that leads to the vault and the key to the vault is hidden in the suit of armor.

The problem is that these ploys are always overturned by the simplest events. Scooby-Doo jumps on the desk looking for a Scooby snack and the desk breaks revealing the hidden compartment. Shaggy casually leans on the bookcase pressing the false book spine that unlocks the door and he falls through. Velma runs into the suit of armor and knocks it over, sending the key flying through the air to land in Shaggy’s hand.

But apparently these well-documented examples of the weakness of security through obscurity have not been enough for some people. Not convinced by the incontrovertible evidence demonstrated by Scooby-Doo and friends, some companies will persist in believing that hiding stuff will keep it safe.

But, that said, it is one thing for a company to believe that security through obscurity will work and quite another for that company to provide a tool that makes it possible for selected people to get around that security.

At this point you might be thinking, “Wow! Now that’s dumb. It couldn’t get any worse!” And guess what, my friend, you’d be wrong because, if that company should then tell the world about what they’ve done, well, they are sitting ducks for anyone who is clever enough and has enough time to figure out how to break the security.

As you might guess, I have an example of this insane thinking for you. And lest you think my example concerns some young, naive, dementedly optimistic startup, let me disabuse you of the notion: The company in question is . . . wait for it, wait for it … yes, it’s Microsoft!

According to several sources, including The Seattle Times, Microsoft has a tool called COFEE – Computer Online Forensic Evidence Extractor – that the company has made available to some law enforcement agencies. Consisting of a USB drive that reportedly provides 150 special programs that make decrypting and analyzing the contents of Windows-based computers much easier, COFEE has been distributed to more than 2,000 officers in 15 countries.
