UK Critical Structures Targeted by Trojan Attacks 102

Posted by Zonk from the beware-greeks-bearing-gifts dept.
ElGanzoLoco writes "The UK's National Infrastructure Security Coordination Centre is reporting that key british infrastructures (government, telecom, transports, banks among others) are under attack by specific, targeted e-mail trojans. According to their report (PDF), 'the emails use social engineering to appear credible, with subject lines often referring to news articles that would be of interest to the recipient. In fact they are "spoofed", making them appear to originate from trusted contacts, news agencies or Government departments.'. The attackers are apparently trying to gather sensitive or secret data. While the NISCC has not been able to precisely trace the attacks' origins, most IPs seem to trace back to Far-East Asia."

    There's no doubt that these attacks will create a political spin, which could be their target in the first place. We all know there are many tensions between western and easter countries, particularly North Korea & China, and U.K. & U.S.A. This also goes hand-in-hand with previous stories saying there are highly skilled cracker armies in North Korea. I would say without a doubt that these are politically motivated.

    According to UK Government operational and configuration guidelines for classified system (primarily JSP440), any system containing CONFIDENTIAL or data with high protective marking just won't be connected to the internet so therefore won't get the mails and therefore won't be able to leak to the internet?

    So how the hell would these PC leak SECRET data at all?

    • So how the hell would these PC leak SECRET data at all?

      IANA, but in my understanding if a PC is compromised by a trojan, there is a lot it can do. Now confidential data may only be held on secure systems, but what happens when Joe from upstairs needs a copy of this, and for ease of work Jim (with a compromised machine) emails it to him, after getting it manualy? A combination of social engineering and use of compromised machines could get you a plethora of sensitive information.

      • The program then needs to magically send data back out from the classified network to the internet, somehow. These networks (certainly all networks containing SECRET data and above) are physically disconnected from other networks and the internet, so I don't understand how this would occur....

        • What I meant was users with physical access to the disconnected networks pass on the information to co-workers through the internet-connected network. It's quite likely, really.

              I was assuming (yes, i know, assumptions...) that users are still going to converse, possibly about the sensitive data, and as such may leak through these trojans monitoring emails.

But in terabyte after terabyte of data on a non-classified network, it's going to be unlikely that a trojan just so happens to leak the protectively marked material.
