Cyber defense by semantics: hacks are now called “computer glitches”

Leave a reply

The New York Stock Exchange is down and United Airlines is not flying for half a day. Naturally, everyone’s wondering, What’s going on? The public wants an explanation from the FBI and the affected institutions, and fast.
The response is quite astounding.
Voila! Cyber security problem solved: from now on all hacks are to be called “computer glitches.” United and the NYSE computer network outages are only the latest glaring examples of a classic bureaucratic solution to the problem – defense by semantics.
This “expert” explanation means two things: a) it’s a fairytale designed for little children and big fools; and b) the “cyber security experts” of the affected entities and the FBI probably have no clue as to what happened. That’s a very good indication of an expertly executed cyber attack – the effect is obvious but the attack has not even been detected — and forget figuring out that “the Chinese” or the “the Russians” did it. Because it is really unfathomable to imagine that programmers working on critical programs like these found “glitches.” Such programs are written and implemented by highly qualified programmers and software engineers and are tested numerous times under all imaginable circumstances. Furthermore, they’ve been running for quite some time with no “glitches” detected, and all those systems have built-in redundancies precisely in case of a “glitch.”
The “glitch” explanation is very convenient for those who failed to provide cybersecurity of this country.
All these events are a clear indication of our massive cyber security failure. This failure was inevitable. On the one hand in the last quarter century widely known cyber attack technology has advanced dramatically, and is becoming increasingly widespread. What a while ago only a few government agencies in the world could do can now be done by a lot of people, often by mere script kiddies, and certainly by our sworn enemies who aren’t restricted in what they can attack—the more damage the better. On the other hand, our cyber security has not advanced at all for the same quarter of a century. This is the inconvenient truth, despite of all the marketing and politically soothing statements from the entrenched cybersecurity establishment.
It is really sad that people responsible and paid for providing our cyber security are getting away with this cyber defense by semantics. No doubt the next step is to make the term “hacking” politically incorrect and make everyone use “computer glitch” instead. When that fairy tale runs out, they’ll think of another term. That’s assuming our computers are still functioning.

The Government wants our encryption keys. Are home keys next?

The just released report by 13 well known cryptographers opposing the US and British governments’ sweeping demand for encryption keys has directly addressed the increasing threat of government’s insatiable thirst for power. Any government objection to this report is bound to be disingenuous.
However, there’s one more angle that begs for further exposure. The overall issue is not a scientific or technical question; it’s an ideological one. The frequently heard loud claim that inevitably we have to give up our privacy so the government can protect us is flatly untrue and hypocritical. It is indeed technologically feasible today to build a system where everyone of us would wear an irremovable collar equipped with cameras, microphones, and GPS that would communicate our location and immediate surroundings every instant “totally securely” to some highly trusted government agency. The government may argue that a) it would only access this information upon some court order; and b) it would solve a lot of crimes and save a lot of lives. True, such a system would make the police’s job very easy, would solve a lot of crimes, and save a lot of lives. But the real question is: do we want to live in that kind of society? In the American spirit the politest answer would be, “Hell, no!” And as always with this kind of hypothetical system criminals would quickly find a solution to neutralize it, leaving us with the situation that only-law abiding citizens would be subject to this massive electronic prison.
Even as we see deeper and deeper assaults on our civil rights and liberty in the manner described above, the government is more than a little shy talking about other intelligence-gathering techniques that require more skill than a slightly trained operator just pushing a few computer keys. These methods are well known among professionals, they have existed for a long time, and can be applied to any target. The drawback of course is that they are less convenient for the operators, require greater skills, and do not include a global bulk collection of information on everyone.
Well, maybe this is just what we, the people, need and want.

A classic hot potato—political hacking

Leave a reply

Media attention to cyber attacks can be divided into two categories: the endless stream of examples of institutions hacked, and cautious descriptions of potential (and very real) horrors of our vital systems being attacked.
But there’s one area of cyber attacks that conspicuously has received little or no media attention: political hacking.
Practically all our electronic systems are vulnerable to cyber attacks to varying degrees. Political systems rank close to the high end of vulnerability, and indeed most of them are virtually undefended against even a low-skilled hacker.
It’s pretty obvious that these systems are extremely valuable targets for some political activists, and certainly for the aggressive ones. It’s not too far-fetched to assume that some of these activists, whatever their focus, either possess hacking expertise themselves or have access to guns for hire, whether for money or some other consideration.
This hacking potential may impact our lives more than we realize. It’s not technically difficult to hack into a voting system and “adjust” the outcome to the hacker’s liking. Such hacking targets can be at any level – from a poll on a local ordinance to allow dogs on the beach to the election for a head of state. Importantly, it’s not easy to detect such interference, and even if done successfully it takes a lot of time. We can only imagine the political mess if a couple of months after an election it’s determined that a group of teenagers (or some mysterious “Russian or Chinese hackers”) materially changed the outcome, and the wrong people were sworn in to their new hard-earned and increasingly expensive jobs.
On a more subtle indirect note such “adjustments” can be made to the results of public opinion polls, manipulating public opinion in a very effective way.
While it’s understandable that nobody wants to discuss this classic case of a very hot potato, nevertheless we have to realize that we ignore this threat at our own peril.

Product Liability—the Unique Position of the Cybersecurity Industry

Leave a reply

There are three points that radically distinguish US cybersecurity industry from any other.
One – every cybersecurity company seems to be the self-declared “world leader in cybersecurity.” This can be easily verified by visiting their websites. I haven’t been able to detect any #2. Surprisingly, comedians and cartoonists don’t explore this hilarious situation.
Two – the industry as a whole is de-facto exempted from any product liability, even any implied warranty liability. This is a truly unique break that the cybersecurity industry has been getting away with for over thirty years. In the US every manufacturer is obligated at the very least to make sure that its products are reasonably fit for their intended uses . For example, a car manufacturer must make sure that its cars are at least drivable and can deliver a user from point A to point B. A hammer manufacturer has to make sure that its hammer handles do not break, at least not before you bring one home. The Uniform Commercial Code (UCC) is very explicit about this, and there have been millions of court cases where this principle has been upheld.
But not for the cybersecurity industry. Every firewall gets hacked even before it’s delivered to the first customer. On a daily basis we hear of “big” cases that one or another organization has been hacked with huge losses for millions of people. And don’t forget that only a small fraction of hacks is detected. We never hear about the undetected “big” cases and thousands of smaller ones. But nobody is held responsible despite of many billions of dollars in losses incurred by individuals, companies, and governments. The Government does promise to prosecute hackers – if they can catch them.
The interesting twist here is that every company assures its customers that their personal information and the money in their accounts is secure. Ironically, they assure their customers before they are hacked, while they are being hacked, and after they’ve been hacked. Somehow we listen to them and nod in agreement.
Three – the cybersecurity industry gets countless billions of our dollars for research and development of cybersecurity products. In fact, we spend more on this in a year than the entire cost of the Apollo program that put a few good men on the Moon. Amazingly, these funds seem to be going into a black hole. Nothing comes back. No product, no results, no responsibility for wasted money– the taxpayers money.
The most remarkable thing about this is that we, the people, have put up with this situation for over thirty years.
On a positive note: this industry should be a bonanza for investors — assured high returns with no risk. Stock brokers should take a note.

Latest cyber lunacy: we are going to sanction the rest of the world!

Leave a reply

In the latest example of the bureaucracy’s detachment from reality, the White House has just announced an executive order to sanction cyber attackers. Not to mention the checkered record of effectiveness of other sanctions, cyber sanctions are very difficult even to fathom.
For starters, who are we going to sanction? The whole history of cyber attacks clearly shows that determining the real source of cyber attacks with any degree of certainty is extremely difficult. Out of the thousands of attackers around the world we are able to identify only a handful in a year. Furthermore, those identified are not the most dangerous ones. The best we can do is to say that an attack came from a certain country.
So, who are we going to sanction — and how?
An individual attacker? Most of the identified hackers are not the most dangerous ones, often just scrip kiddies. But even then, how are we going to sanction them? Prohibit a teenager from the Ukraine to enter the United States? He doesn’t have the money to come here anyway. Bar him from McDonalds? He’ll find another place to get a hamburger. Prohibit a cyber dude from Nigeria from exporting oil? He’s unlikely to have any. Deny a sale of an F-16 to a company in Croatia? They probably don’t have a hangar to keep it in anyway.
A country? Unlikely. It’s a well known fact that most of the attacks, and definitely the most damaging ones, are “bounced” many times through “innocent” computers in other countries before being sent to the target. Given that, we’ll rapidly end up sanctioning the rest of the world. While this would become perpetual fodder for the press, it would be unlikely to have any real impact on cyber attacks. If anything, it would even increase them, when they start sanctioning us in retaliation. And chances are their sanctions would be more damaging than ours.
Besides, cyber attacks are already a felony anyway. That should be sanction enough — though it doesn’t seem to work.
The big question is, do we really understand what we’re doing in cybersecurity? It doesn’t seem so.
A better solution may be to sanction our own bureaucracy.

Latest solution: Share your cyber misery

There was a great deal of anticipation about President Obama’s participation in the recent conference on cybersecurity at Stanford University, in the heart of Silicon Valley, where he met with high-tech company executives last week.
It wasn’t a shocking surprise, however, that the Government’s proposal, to be enshrined into a Presidential Order, in reality only boils down to a call for sharing misery tales between the Government and private companies. Once the political rhetoric is stripped away this approach doesn’t offer any improvement in cyber security. The reality is that hacks are usually discovered months or even years after the fact, when all the damage has already been done. That’s assuming the hack is even detected in the first place.
It’s not the best kept secret in town that most hacks, and certainly the most dangerous ones, are rarely or never detected, or only long after the fact. A great example is the recently announced international multi-bank hack that netted somewhere between $300 million and $1 billion to the unknown attackers. See http://www.nytimes.com/2015/02/15/world/bank-hackers-steal-millions-via-malware.html?emc=edit_th_20150215&nl=todaysheadlines&nlid=58721173&_r=0
The vagueness in the loss assessment speaks very loudly to how little the cyber security experts involved know about the hack even now. And, of course, they haven’t a clue as to who did it. Not to mention that it took them two years to discover the loss.
On the more optimistic side there is a rising public awareness of the problem that sooner or later will lead to a public demand for the development of a true cyber security technology. Unfortunately, this is unlikely before the pain from cyber attacks becomes really intolerable, probably as a result of a massive loss of human life.

Encryption: panacea or just an expensive “do something”?

Leave a reply

Once in a while we see a common cyber call to arms: “Let’s use data encryption and, voila, our problems will be over.” A typical example of this is the AP article http://cnsnews.com/news/article/no-encryption-standard-raises-health-care-privacy-questions.
This is a very common misconception. Encryption per se does not protect against hacking. Surely, encrypted files look impressive, with their very long strings of seemingly random characters. It must be mindboggling for a casual observer to imagine that anyone can actually decipher that without the secret key.
However, the reality is vastly different.
Strength of encryption is based on two main ingredients – the encryption algorithm and the secret key. Most encryption algorithms, and certainly all commercially available algorithms, are well known. They have been researched, and solutions—the ability to decrypt them without the secret key—have been found for most of them. The only undefeated algorithm so far remains the so-called “one time pad,” where the key is used only once. But even that algorithm’s strength rests on the quality and security of the key — issues that are far from trivial.
However, the main practical problem with encryption is the distribution system for the key. As in the example of a health system cited above, we are talking about a massive database with many millions of records. Sure, it’s not too difficult to encrypt all that data. But then what? The database has many legitimate users, sometimes thousands, and each one of them must have the secret key. It’s not difficult to obtain the key, one way or another, from at least one of them. Such a single breach would defeat the whole encryption scheme. I’ve often heard someone proudly declaring at a party, “I encrypt all data files in my computer.” Sometimes I will casually ask, “But where do you keep your key?” The answer invariably is, “In the computer.” Usually that person doesn’t understand that the key in his computer is also available to anyone who bothers to hack into his computer.
All in all, data encryption is a good concept, but the practicality of its deployment in databases with many users can only protect against middleschoolers. It would have marginal protection against smart highschoolers, and it would certainly be fruitless against professional cyber attackers.
Encryption per se would be just another expensive exercise in wishful thinking. It should be clearly understood: ENCRYPTION PER SE DOESNOT PROTECT AGAINST HACKING.

Power grid: when cyber lines cross

Leave a reply

We have very little time to cure our stone age cyber defensive technology.
The CNN story citing testimony by Admiral Michael Rogers, head of U.S. Cyber Command, to a House Select Intelligence Committee November 20 sounded like shocking news. He stated that China can take down our power grid. http://www.cnn.com/2014/11/20/politics/nsa-china-power-grid/index.html

Shocking as it may be, if this is still “news,” surprise, surprise — it’s been known to everyone who was anyone in cyber security for over 25 years. First it was just the Russians, then the Chinese, then some vague criminals acting on behalf of “nation-states” were gradually added to the list.
Never mind the Russians and the Chinese – they also both have enough nuclear weapons to kill every squirrel in America. What is really troubling is the cyber security trend. Our cyber defensive capabilities have hardly improved for over a quarter-century. However, hackers’ attacking capabilities are improving constantly and dramatically. This is not a good equation — sooner or later these lines will cross. This means that a large number of unknown hackers will be able to take down our power grid and also decimate our power-intensive facilities, such as oil refineries, gas distribution stations, and chemical factories.
Now, think terrorists. They would be delighted to do exactly that, whether you kill them afterwards or not. This isn’t news, but it’s an increasingly troubling reality. We have very little time to cure our stone age cyber defensive technology. But that requires changing the current equation and making cyber defense inherently more powerful that the offense. That won’t happen until the doomed legacy password and firewall paradigms are abandoned and replaced by fundamentally different technologies.

Cybersecurity: 3% misery

Leave a reply

Whenever we make a journey, physical or otherwise, it’s important to understand where we are before we decide what direction to take. Otherwise we’ll get nowhere. This is as true as ever in cybersecurity.
Russian cybersecurity portal cybersecurity.ru, citing security research company Group-IB, recently stated that only 3% of cyberattacks are detected and countered by bank IT experts. This conclusion notably relates to institutions that boast superior protection against cyber attacks. Mere mortals are obviously less successful.
That 3% is a significant drop from the 10% average attack detection reported by a similar British study a decade ago. More important, this is startling evidence of our deepening cyber security misery. What’s really vital here is for us to recognize the reality. And that reality is frightening. All these almost daily proud statements of detected “sophisticated cyber attacks,” usually followed by bravado announcements that the attack has been defeated and from now on the particular company is reliably protected, are nothing but wishful thinking.
Even if these optimistic announcements were true, the reality is that they’re based on just 3% of cyber attacks. Furthermore, these 3% represent the least sophisticated, often clumsy attacks, while the better than 97% of the attacks go undetected — and we have no idea what they are, nor what we lost in those attacks.
Until we acknowledge the reality of where we actually are in cybersecurity, we’re getting nowhere, faster and faster.

EU Cyber Incompetence

Leave a reply

Utter incompetence of high-level officials is not exactly a scarce phenomenon. However, it’s rarely displayed so vividly as it was by Troels Oerting, the head of Europol’s Cybercrime Center, in his recent interview with the BBC’s Tech Tent radio show.
Mr. Oerting proudly declared that international law enforcement just needs to target a “rather limited group of good programmers.” He went further, proudly stating “We roughly know who they are. If we can take them out of the equation then the rest will fall down.” Voila, easy and simple. Arrest the 100 known dudes and cybercrime disappears. He didn’t specify what it means to know “roughly”–you either do or you don’t, and that is exactly, not “roughly.”
The man obviously hasn’t a clue. The trouble is that he’s speaking for Europol and the EU. And the idea that the EU’s main cybercrime law enforcement unit assesses the cybercrime situation this way is truly troubling. It would simply mean that the cybercriminals don’t have much to worry about.
The reality is drastically different. There are many thousands of programmers around the world good enough to hack most of the attractive targets. Many of them, for one reason or another, are disappointed with their employment or personal situation. Given the current dire state of our cybersecurity, making a few bucks off easy targets is really tempting. This temptation looks even more attractive if the target is a rich bank or some large allegedly unethical company. This often satisfies the conscience of many of the hackers. The continuing deterioration of the European economy worsens the situation.
Add the “script kiddies” to the equation and Mr. Oerting’s job becomes even harder than he probably can envision in his worst nightmares. He should also know that really good programmers only publish their crumbs for the script kiddies, scripts they developed long ago. They keep their best stuff for themselves.
Furthermore, many of these off-the-grid programmers have their own very large botnets capable of performing rather sophisticated operations that they can offer to all sorts of customers as a service.
All in all, Mr. Oerting should urgently realize that he is mainly dealing with the mediocre cybercriminals who are not good enough to be stealthy. Really good “top-100” programmers don’t get caught. I wouldn’t be at all surprised if one of them, having read Mr. Oerting’s statements, would hack his next target through this top EU cyber cop’s computer, just to demonstrate the point.
