![]() The ways to achive these minimizations are many and varied and also supprisingly for some form part of Layer 8 and up “Perimeter Minimization and Control”. The first is to minimize the information per unit of energy and secondly minimize the information per unit of time. The reality is there are only two ways to limit the effects of energy based security issues be they by emission or susceptibility. This was even though the mechanisms of it were talked about publicly and openly since the 1980’s as ElectroMagnetic Compatability (EMC) it rarely if ever crossed the mental gap in most security practitioners heads… Thus failed to recognise the potential of the “black arts” of “Susceptibility attacks” developed by those who did. Put simply anyone who actually understood the basic physics they were taught at school prior to being a teenager, could with a little thought have realised that what was needed was,Įven of those in the security domain who had heard of what became known as TEMPEST or EmSec, apparently few of them realised that the channels and transducers by which information gets transported are bidirectional. Why this has taken so long to become apparent to the majority of security practitioners, is a cause of puzzlement. ![]() Unfortunatly as is now obvious to those who can read an “air gap” is insufficient to stop information leakage due to those fundemental laws of nature. The way to deal with information leakage below Layer 8 was known as “air gapping” and “perimeter minimization and control” from Layer 8 upwards. The latter are side effects of the laws of physics and thermodynamics, thus ever present if not eternal foes. The former are considered to be forms of insider attacks, but they also occure due to what are excused as “poor engineering choices” in place from before day zero of any project. Information leakage comes in two basic forms intentional and unintentional. It manifests it’s self in side channels, increased complexity, increased attack surface and way too much privilege in individual entities and other lack in their control. It applies from below Layer 0 all the way through Layer 9 and above in the computing stack. I have a couple of pieces of advice I trot out from time to time, for those wishing to limit disclosure damage.įirst and formost though one that defines the basic reason information leaks in one way or another from repositories, Such do not exist on any computer system interfaced to an unclassified network.Īnd as Ed Snowden and several others have demonstrated, secrets can not be kept on computers connected to classified networks either. Note that the Hague-based Organization for the Prohibition of Chemical Weapons is on the list, hacked in 2000. Now that we know they held things back, there could easily be more releases.ĮDITED TO ADD (11/6): More on the NSA targets. I thought that the original Shadow Brokers dump was everything. Honestly, I am surprised by this release. The data is old, but you can see if you’ve been hacked. According to this spreadsheet, the servers were mostly running Solaris, an operating system from Sun Microsystems that was widely used in the early 2000s. If valid, the list could be used by various organizations to uncover a decade’s worth of attacks that until recently were closely guarded secrets. Chief among them are configuration settings for an as-yet unknown toolkit used to hack servers running Unix operating systems. The dump also includes various other pieces of data. Vitali Kremez, a senior intelligence analyst at security firm Flashpoint, also provides useful analysis here. In all, the targets were located in 49 countries, with the top 10 being China, Japan, Korea, Spain, Germany, India, Taiwan, Mexico, Italy, and Russia. The timestamps included in the leak indicate that the servers were targeted between Augand August 18, 2010. This one includes a list of hacked sites.Īccording to analyses from researchers here and here, Monday’s dump contains 352 distinct IP addresses and 306 domain names that purportedly have been hacked by the NSA. There’s another leak of NSA hacking tools and data from the Shadow Brokers.
