The Unbearable Lightness of Being an APT

April 25, 2012 2 comments

Or better “The Unbearable Lightness of (Human) Beings and APTs”. Immediately after my post on Cyber Weapons, I was pointed out that APTs are not Cyber Weapons. On a more general perspective, APTs are not things but (groups of) human beings who have the capability and the intent to target specific entries with multi-factor attacks. Said in few words an APT is not a “what” but is a “who”. On the other hand, how many could afford to hire (and pay) a double agent capable of implanting a malware inside a nuclear complex through an infected USB thumb?

An Oxford dictionary for Information Security has not already been published, hence this term is commonly used to refer to cyber threats or long-term sophisticated hacking attacks. The latter is the interpretation closer to what I meant in compiling the chart.

Middle East Cyber War: Revenge Of The Drones

In the same hours in which I was publishing my post on Cyber Weapons, news agencies all around the world have begun to release (few) details about a new alleged Cyber Attack targeting the Iranian Oil Ministry, the National Iranian Oil Company and several other state-owned businesses.

The attack has been confirmed by a spokesman of the Iranian Oil Ministry, who also stressed that critical data have not been damaged or lost in the attack. Anyway, as a consequence of the Cyber Attack albeit as a precaution Internet access to several oil refineries has been cut off.

Of course Iran is not new to Cyber Attacks targeting Critical Infrastructures (do you remember Stuxnet and the possible hoax of Duqu Stars?), in any case it is too soon to draw any connection with Stuxnet or any other kind of State-Sponsored Attack, even because, according to the scant information available, only a server providing public information has been harmed.

Probably this malware has nothing to deal with cyber weapons but, just for fun, I cannot help but notice that this alleged Cyber Attack came in the same day in which, among many doubts, Iran has announced to have reverse-engineered the U.S. stealthy RQ-170 Sentinel drone captured by Iran in December 2011.

The revenge of the reverse-engineered drone?

What is a Cyber Weapon?

What is a Cyber Weapon? At first glance this seems an immediate question to answer, but should anyone try to analyze the meaning of this term more deeply, probably he would be quite surprised and disappointed in discovering that the answer is not so immediate since an exact definition has not been given (at least so far).

A real paradox in the same days in which The Pentagon, following the Japanese Example, has unveiled its new strategy aimed to dramatically accelerate the development of new Cyber Weapons. And do not think these are isolated, fashion-driven examples (other nations are approaching the same strategy), but rather consider them real needs in the post-Stuxnet age, an age in which more and more government are moving their armies to the fifth domain of war [you will probably remember the (in)famous episode, when F-Secure was able to discover Chinese Government launching online attacks against unidentified U.S. Targets].

Recently Stefano Mele, a friend and a colleague of the Italian Security Professional Group, tried to give an answer to this question in his paper (so far only in Italian but it will be soon translated in English) where he analyzes Cyber Weapons from a legal and strategical perspective.

As he points out “Correctly defining the concept of Cyber Weapon, thus giving a definition also in law, is an urgent and unavoidable task, for being able to assess both the level of threat deriving from a cyber attack, and the consequent political and legal responsibilities attributable to those who performed it”. Maybe this phrase encloses the reason why a coherent definition has not been given so far: a cyber weapon is not only a technological concept, but rather hides behind it complex juridical implications.

Having this in mind, according to Stefano’s definition: a cyber weapon is:

A device or any set of computer instructions intended to unlawfully damage a system acting as a critical infrastructure, its information, the data or programs therein contained or thereto relevant, or even intended to facilitate the interruption, total or partial, or alteration of its operation.

The above definition implies that cyber weapons may span in theory a wide range of possibilities: from (D)DoS attacks (which typically have a low level of penetration since they target the “surface” of their targets), to “tailored” malware like Stuxnet, characterized by a high intrusiveness and a low rate of collateral damages.

One could probably argue whether a cyber weapon must necessarily generate physical damages or not, in which case, probably, Stuxnet, would be the one, so far, to encompass all the requirements. In any case, from my point of view, I believe the effects of a cyber weapon should be evaluated from its domain of relevance, the cyberspace, with the possibility to cross the virtual boundaries and extend to the real world (Stuxnet is a clear example of this, since it inflicted serious damages to Iranian Nuclear Plants, including large-scale accidents and loss of lifes).

With this idea in mind, I tried to build a model to classify the cyber weapons according to four parameters: Precision (that is the capability to target only the specific objective and reduce collateral damages), Intrusion (that is the level of penetration inside the target), Visibility (that is the capability to be undetected), and Easiness to Implement (a measure of the resource needed to develop the specific cyber weapon). The results, ranging from paintball pistols to smart bombs, are summarized in the above chart.

As you may notice, in these terms a DDoS attack is closer to a paintball pistol: the latter has a low level of penetration and the effects are more perceived than real (it shows the holder’s intention to harm the victim rather than constituting a real danger ), nevertheless it may be used to threaten someone, or worst to make a robbery. The same is true for a DDoS, it is often used to threaten the target, its action stops at the surface and usually the effects are more relevant in terms of reputation of the victims than in terms of damages done. Nevertheless, for the targets, it may lead to an interruption of service (albeit with no physical damages) and monetary losses.

On the opposite site there are specific “surgical” APTs: they have a high level of penetration with reduced collateral damages, they are able to go hidden for long time, but require huge investments to be developed, which ultimately make their adoption not so easy.

Of course, in between, there is a broad gray area, where the other Cyber Weapons reside depending on their positioning according to the four classification parameters identified… So, at the end what do you think? Do you agree with this classification?
