Why Antisec matters

A couple of weeks ago the FBI announced the arrest of five members of the antisec-logo-100337062-orighacking group LulzSec. We now know that these arrests were facilitated by ‘Anonymous’ leader* “Sabu“, who, according to court documents, was arrested and ‘turned’ in June of 2011. He spent the next few months working with the FBI to collect evidence against other members of the group.

This revelation is pretty shocking, if only because Anonymous and Lulz were so productive while under FBI leadership. Their most notable accomplishment during this period was the compromise of Intelligence analysis firm Stratfor — culminating in that firm’s (rather embarrassing) email getting strewn across the Internet.

This caps off a fascinating couple of years for our field, and gives us a nice opportunity to take stock. I’m neither a hacker nor a policeman, so I’m not going to spend much time why or the how. Instead, the question that interests me is: what impact have Lulz and Anonymous had on security as an industry?

Computer security as a bad joke

To understand where I’m coming from, it helps to give a little personal background. When I first told my mentor that I was planning to go back to grad school for security, he was aghast. This was a terrible idea, he told me. The reality, in his opinion, was that security was nothing like Cryptonomicon. It wasn’t a developed field. We were years away from serious, meaningful attacks, let alone real technologies that could deal with them.

This seemed totally wrong to me. After all, wasn’t the security industry doing a bazillion dollars of sales ever year? Of course people took it seriously. So I politely disregarded his advice and marched off to grad school — full of piss and vinegar and idealism. All of which lasted until approximately one hour after I arrived on the floor of the RSA trade show. Here I learned that (a) my mentor was a lot smarter than I realized, and (b) idealism doesn’t get you far in this industry.

Do you remember the first time you met a famous person, and found out they were nothing like the character you admired? That was RSA for me. Here I learned that all of the things I was studying in grad school, our industry was studying too. And from that knowledge they were producing a concoction that was almost, but not quite, entirely unlike security.

Don’t get me wrong, it was a rollicking good time. Vast sums of money changed hands. Boxes were purchased, installed, even occasionally used. Mostly these devices were full of hot air and failed promises, but nobody really cared, because after all: security was kind of a joke anyway. Unless you were a top financial services company or (maybe) the DoD, you only really spent money on it because someone was forcing you to (usually for compliance reasons). And when management is making you spend money, buying glossy products is a very effective way to convince them that you’re doing a good job.

Ok, ok, you think I’m exaggerating. Fair enough. So let me prove it to you. Allow me to illustrate my point with a single, successful product, one which I encountered early on in my career. The product that comes to mind is the Whale Communications “e-Gap“, which addressed a pressing issue in systems security, namely: the need to put an “air gap” between your sensitive computers and the dangerous Internet.

Now, this used to be done (inexpensively) by simply removing the network cable. Whale’s contribution was to point out a major flaw in the old approach: once you ‘gap’ a computer, it no longer has access to the Internet!

Hence the e-Gap, which consisted of a memory unit and several electronic switches. These switches were configured such that the memory could be connected only to the Internet or to your LAN, but never to both at the same time (seriously, it gives me shivers). When data arrived at one network port, the device would load up with application data, then flip ‘safely’ to the other network to disgorge its payload. Isolation achieved! Air. Gap.

(A few pedants — damn them — will try to tell you that the e-Gap is a very expensive version of an Ethernet cable. Whale had a ready answer to this, full of convincing hokum about TCP headers and bad network stacks. But really, this was all beside the point: it created a freaking air gap around your network! This apparently convinced Microsoft, who later acquired Whale for five times the GDP of Ecuador.)

Now I don’t mean to sound too harsh. Not all security was a joke. There were plenty of solid companies doing good work, and many, many dedicated security pros who kept it from all falling apart.

But there are only so many people who actually know about security, and as human beings these people are hard to market. To soak up all that cybersecurity dough you needed a product, and to sell that product you needed marketing and sales. And with nobody actually testing vendors’ claims, we eventually wound up with the same situation you get in any computing market: people buying garbage because the booth babes were pretty.**

Lulz, Anonymous and Antisec

I don’t remember when I first heard the term ‘Antisec’, but I do remember what went through my mind at the time: either this is a practical joke, or we’d better harden our servers.

Originally Antisec referred to the ‘Antisec manifesto‘, a document that basically declared war on the computer security industry. The term was too good to be so limited, so LulzSec/Anonymous quickly snarfed it up to refer to their hacking operation (or maybe just part of it, who knows). Wherever the term came from, it basically had one meaning: let’s go f*** stuff up on the Internet.

Since (per my expanation above) network security was pretty much a joke at this point, this didn’t look like too much of a stretch.

And so a few isolated griefing incidents gradually evolved into serious hacking. It’s hard to say where it really got rolling, but to my eyes the first serious casualty of the era was HBGary Federal, who — to be completely honest — were kind of asking for it. (Ok, I don’t mean that. Nobody deserves to be hacked, but certainly if you’re shopping around a plan to ‘target’ journalists and civilians you’d better have some damned good security.)

In case you’re not familiar with the rest of the story, you can get a taste of it here and here. In most cases Lulz/Anonymous simply DDoSed or defaced websites, but in other cases they went after email, user accounts, passwords, credit cards, the whole enchilada. Most of these ‘operations’ left such a mess that it’s hard to say for sure which actually belonged to Anonymous, which were criminal hacks, and which (the most common case) were a little of each.

The bad

So with the background out of the way, let’s get down to the real question of this post. What has all of this hacking meant for the security industry?

Well, obviously, one big problem is that it’s making us (security folks) look like a bunch of morons. I mean, we’ve spent the last N years developing secure products and trying to convince people if they just followed our advice they’d be safe. Yet when it comes down to it, a bunch of guys on the Internet are walking right through it.

This is because for the most part, networks are built on software, and software is crap. You can’t fix software problems by buying boxes, any more than, say, buying cookies will fix your health and diet issues. The real challenge for industry is getting security into the software development process itself — or, even better, acknowledging that we never will, and finding a better way to do things. But this is expensive, painful, and boring. More to the point, it means you can’t outsource your software development to the lowest bidder anymore.

Security folks mostly don’t even try to address this. It’s just too hard. When I ask my software security friends why their field is so terrible (usually because they’re giving me crap about crypto), they basically look at me like I’m from Mars. The classic answer comes from my friend Charlie Miller, who has a pretty firm view of what is, and isn’t his responsibility:

I’m not a software developer, I just break software! If they did it right, I’d be out of a job.

So this is a problem. But beyond bad software, there’s just a lot of rampant unseriousness in the security industry. The best (recent) example comes from RSA, who apparently forgot that their SecurID product was actually important, and decided to make the master secret database accessible from a single compromised Windows workstation. The result of this ineptitude was a series of no-joking-around breaches of US Defense Contractors.

While this has nothing to do with Anonymous, it goes some of the way to explaining why they’ve had such an easy time these past two years.

The good

Fortunately there’s something of a silver lining to this dark cloud. And that is, for oncepeople finally seem to be taking security seriously. Sort of. Not enough of them, and maybe not in the ways that matter (i.e., building better consumer products). But at least institutionally there seems to be a push away from the absolute stupid.

There’s also been (to my eyes) a renewed interest in data-at-rest encryption, a business that’s never really taken off despite its obvious advantages. This doesn’t mean that people are buying good encryption products (encrypted hard drives come to mind), but at least there’s movement.

To some extent this is because there’s finally something to be scared of. Executives can massage data theft incidents, and payment processors can treat breaches as a cost of doing business, but there’s one thing that no manager will ever stop worrying about. And that is: having their confidential email uploaded to a convenient, searchable web platform for the whole world to see.

The ugly 

The last point is that Antisec has finally drawn some real attention to the elephant in the room, namely, the fact that corporations are very bad at preventing targeted breaches. And that’s important because targeted breaches are happening all the time. Corporations mostly don’t know it, or worse, prefer not to admit it.

The ‘service’ that Antisec has provided to the world is simply their willingness to brag. This gives us a few high-profile incidents that aren’t in stealth mode. Take them seriously, since my guess is that for every one of these, there are ten other incidents that we never hear about.***

In Summary

Let me be utterly clear about one thing: none of what I’ve written above should be taken as an endorsement of Lulz, Anonymous, or the illegal defacement of websites. Among many other activities, Anonymous is accused of hacking griefing the public forums of the Epilepsy Foundation of America in an attempt to cause seizures among in its readers. Stay classy, guys.

What I am trying to point out is that something changed a couple of years ago when these groups started operating. It’s made a difference. And it will continue to make a difference, provided that firms don’t become complacent again.

So in retrospect, was my mentor right about the field of information security? I’d say the jury’s still out. Things are moving fast, and they’re certainly interesting enough. I guess we’ll just have to wait and see where it all goes. In the meantime I can content myself with the fact that I didn’t take his alternative advice — to go study Machine Learning. After all, what in the world was I ever going to do with that?

How not to redact a document: NHTSA and Toyota edition

Allow me to apologize in advance for today’s offtopic post, which has nothing to do with crypto. Consider it a reflection on large organizations’ ability to manage and protect sensitive data without cryptography. Report card: not so good.

Some backstory. You probably remember that last year sometime Toyota Motors had a small amount of trouble with their automobiles. A few of them, it was said, seemed prone to sudden bouts of acceleration. Recalls were issued, malfunctioning throttle cables were held aloft, the CEO even apologized. That’s the part most people have heard about.

What you probably didn’t hear too much about (except maybe in passing) was that NASA and NHTSA spent nearly a year poring through the Toyota engine control module code to figure out if software could be at fault. Their report, issued in February of this year, basically said the software was ok. Or maybe it didn’t. It’s not really clear what it said, because major portions — particularly of the software evaluation section — were redacted.

Now, like every major redaction of the digital age, these redactions were done thoughtfully, by carefully chopping out the sensitive portions using sophisticated digital redaction software, designed to ensure that the original meaning could never leak through.

Just kidding!

Seriously, as is par for the course in these things, NHTSA just drew big black squares over the parts they wanted to erase.

And this is where we get to the sophistication of organizations when it comes to managing secure data. You see, NHTSA released these reports online in February 2011, as a response to a FOIA request. They were up there for anybody to see, until about April — when somebody noticed that Google was magically unredacting these documents. Whoops. Time to put up some better documents!

Naturally NHTSA also remembered to contact Archive.org and ask that the old reports be pulled off of the Wayback Machine. No, really, I’m just kidding about that, too.

Of course, they’re all cached there for all to see, in their full un-redactable glory. All it takes is a copy and paste. For example, take this portion:

Where the redacted part decodes to:

The duty % is converted into three boolean flags, a flag describing the sign of the duty, a flag if the absolute value of the duty is greater than or equal to 88%, and a flag if the absolute value of the duty is less than 1%.  The 64 combinations of these flags and their previous values are divided into ten cases. Of the ten cases, five will open the throttle, two of the five will make the throttle more open than currently but not wide open, two will provide 100% duty instantaneously, and one will perpetually open the throttle. Any duty command from the PID controller greater than or equal to 88% will perpetually open the throttle and lead to WOT [wide open throttle]. This also means that any duty greater than 88% will be interpreted by the hardware as a 100% duty command.


So what’s the computer security lesson from this? Once data’s out on the wire, it’s gone for good. People need to be more careful with these kinds of things. On the bright side, this was just information, possibly even information that might be useful to the public. It’s not like it was sensitive source code, which I’ve also seen find its way onto Google.
