The Risk of a Categorical Denial – The MilitarySingles.com hack

The first I read on the alleged MilitarySingles.com hack was this:

With the usual link to pastebin for more details. So far a simple hack story. Nothing to see here. Time to move on.

But then the same story came up at The Office of Inadequate Security, along with a denial by the company that runs MilitarySingles.com. The denial reads:

“After a thorough investigation by our company programmers, it is our conclusion that our database was not hacked and that the claims of the Lulzsec group are completely false. Here are a couple points to note:

1. The total number of users in our database does not even closely match the number they have claimed to have exposed.

2. All user passwords in our database are encrypted and secure.

3. The location of the file the above user posted is in a repository directory on our website for user’s photos. The above user simply uploaded a photo of the Lulzsec group and does not mean in any way whatsoever that they were successful in actually hacking our service.

4. MilitarySingles.com was down for a few hours on March 25th due to regularly scheduled maintenance, not due to any outside activity.

We have taken measure to confirm our website and it’s database is secure and safe for our members, and will continue to do so. We are unable to confirm that the so-called checklist of email addresses have actually come from our user database.”

Sounds like a pretty comprehensive and categorical denial.

This was followed by:

Now things are looking interesting. Hackers claim to have hacked a website and downloaded everything; the company that runs it claims that they didn’t.

So Were They Hacked?

A quick look at the files (which, since the company wasn’t hacked, presumably aren’t theirs) reveals:

  • A file MilitaryDatabase.rar which is a compressed SQL file containing a 500MB dump of a database. It contains an administrator password (in clear and hashed), recent chat sessions, user profiles, email addresses, and hashed passwords. The chat sessions often make references to US military deployments and bases.
  • A file Military.rar which is a compressed 57 MB text file containing user email addresses, names, and hashed passwords. There are 170,937 records.

The IQ Security Blog has analyzed the database dump. It contained the unsalted MD5 hashes of user passwords. This makes them particularly easy to crack, because it’s possible to pre-compute the hashes of common passwords. IQ Security report that they managed to crack 151,972 of the 163,792 password hashes in just 9 hours.

“It Never Happened”

I guess we can all breath a big sigh of relief that the breach never happened, because, as MilitarySingles.com’s FaceBook page read on April 1st.

It’s still possible LulzSec hackers had an extreme case of obsessive-compulsive disorder and put together 570MB of fabricated data in some form of elaborate April Fool’s joke.

The Problem of Denial

What will happen if the hackers were correct?

That’s the problem with a categorical denial like the one above. It’s a rookie PR mistake. You do well if you are right, but you are damned if you are wrong.

A better approach might have been to use a non-denial denial, as popularized by Woodward and Bernstein in their book on the Watergate Scandal, “All The President’s Men“. Say you don’t have any evidence yet. Say that LulzSec are known to issue misleading statements designed to mislead and confuse. Recommend everyone change their passwords as a precaution.

But don’t issue what sounds like a categorical denial and then go silent as conflicting evidence mounts. Who is going to believe or trust you now?

As it is, it’s going to be quite interesting to see how this one plays out.

The Questionable Wisdom of Crowds

There’s often far too much credibility given to the wisdom of crowds.

The original much-quoted observation by Francis Galton that the average of a group’s estimates of something (beans in a jar, weight of a butchered ox) can be much better than an individual estimate may often be true, but in some circumstances it may be much worse. This is frequently forgotten.

I just came across an excellent ten minute presentation by Tom Scott which explains some of those other circumstances, providing a convincing live demonstration using audience tweets. It’s worth having on hand for those occasions when you are tempted (or told) to simply average people’s estimates of the likelihood of an event or of the impact of a disruption.

What’s worth $4.9billion and fits in the back of your car?

Marauder: Picture Wikipedia

If your had to transport something worth $4.9 billion dollars, you would do so in a pretty awesome vehicle, wouldn’t you? Perhaps you would use something like the Marauder, pictured above, to do the job.

You certainly wouldn’t leave it in the back of a car, would you? But that’s what happened recently to something worth $4.9 billion belonging to the the U.S. Department of Defense.

So what is worth $4.9 billion dollars and fits in the back of a car?

The answer is data. According to this report in the Army Times backup tapes containing personal medical and financial data on 4.9 million people being transported by an employee of Science Applications International Corp disappeared from the back of a car while in transit to a secure facility on September 13th. A class action lawsuit is claiming $1,000 on behalf of every person whose data was lost, as well as free credit monitoring for each of them for a year.

Is the data worth $4.9 billion: probably not. Is there a potential liability of $4.9 billion. Perhaps.

It’s certainly something that should be considered when transporting or storing data. The question to ask is not just “how much is this data worth to us?” but “how much might this data cost us if it gets stolen?”


(If you enjoy their sense of humor, you might enjoy this road test of a Maraudercarried out by the UK BBC Top Gear team. Their road test includes a comparison with the Hummer, including the effects of a charge of 7lbs of plastic explosive placed beneath the vehicle.)
