Market share! It’s an easy answer, but not the only one.

In 2011, Apple was estimated to account for over 5% of worldwide desktop/laptop market share. This barrier was a significant one to break – Linux maintains under 2% market share and Google ChromeOS even less. This 15 year peak coincided with the first exploration by the aggressive FakeAv/Rogueware market targeting Apple computers, which we discovered and posted in April 2011 and later in May 2011, which no longer seem to be such an odd coincidence. Also, the delay in Apple malware until now most likely was not because Apple exploits were unavailable, or because the Mac OS X system is especially hardened. The 2007 “Month of Apple Bugs” demonstrated that the Mac OS X and supporting code is full of exploitable flaws. Safari, Quicktime, and other software on Apple devices is regularly exploited during pwnage contests, but widespread cybercrime attention hadn’t caught on until this past year.

Nadim Kobeissi, master hacker, summoned for interrogation multiple times as a teenager by cyber-intelligence authorities in Beirut, Lebanon, sat in the backyard of a restaurant in Brooklyn, astounded that he was being treated to lunch.  “Please,” he protested, “you shouldn’t pay for my omelet.”

Mr. Kobeissi, 21, now a college student in Montreal, spent the weekend in New York City with elders of his tribe, software code writers who have ambitions that do not involve making suitcases of money off clever applications for sharing photographs online.

This group was building a project called Cryptocat, which has a simple, countercultural goal: people should be able to talk on the Internet without being subjected to commercial or government surveillance.

Assessing the security of internet-connected critical infrastructures. Security and Communications Networks [in press]. doi:10.1002/sec.399  [Full text can be requested by UMUC students / faculty from DocumentExpress.]

Because the Internet of Things (IoT) pervasively extends to all facets of life, the “things” are increasingly extending to include the interconnection of the Internet to critical infrastructures (CIs) such as telecommunication, power grid, transportation, e-commerce systems, and others. The objective of this paper is twofold: (i) addressing IoT from a CI protection (CIP) and connectivity viewpoint, and (ii) highlighting the need for security quantification to improve the quality of protection (QoP) of CIs. Using a financial infrastructure as an example, a CIP and trust quantification perspective is built up. To this end, we are developing a novel security metrics-based approach to assess and thereon enhance the CIP. We focus on the communication level of the CI where IoT is playing an increasingly important role with respect to sensing and communication across CI elements. Determining the security and dependability level of the communication over the CI constitutes a basic precondition for assessing the QoP of the whole CI, which is needed for any efforts to improve this QoP. Because metrics play a central role for such quantification, this paper develops their QoP use from an IoT perspective, and a reference implementation along with experimental results is presented.

Building on systems-based philosophy, theory, methodology, and practice, the challenges associated with modeling, assessing, managing, and communicating the multidimensional risk to cyberinfrastructure systems (CIS) serviced by cloud computing technology (CCT) as systems of systems (SoS) are explored. The article raises concerns about the euphoria in the literature about CCT and stresses the importance of understanding the complex process of modeling, assessing, managing, and communicating the risks associated with CIS-CCT. Several themes are highlighted: the theory of scenario structuring; the epistemology of the states of the CIS-CCT systems; the role of systems integration in CIS-CCT; the risk to CIS-CCT from malicious insiders’ intrusion; the complex definition and quantification of the risk function associated with CIS-CCT systems; and modeling the multiple perspectives of CIS-CCT, focusing on hierarchical holographic modeling (HHM) and phantom system models (PSM). The paper concludes with an epilogue and list of references.

Two cybersecurity bills were approved by House committees on Wednesday. Those bills — as well as a third cybersecurity bill — are expected to be considered on the House floor as soon as next week.  The House Oversight and Government Reform Committee passed HR 4257, the 2012 Federal Information Security Amendments Act, which would require agencies to continuously monitor the security of federal information systems. The bill would also require agencies to appoint a chief information security officer or senior official to oversee information security programs and enforce compliance.

Given the strong feelings that Microsoft’s actions have engendered in the Fox IT folks and among the larger security community, I reached out to Richard Boscovich, a former U.S. Justice Department lawyer who was one of the key architects of Microsoft’s legal initiative against ZeuS. One complaint I heard from several researchers who believed that Microsoft used and published data they uncovered was that the company kept the operation from nearly everyone. I asked Boscovich how this operation was different from previous actions against botnets such as Rustock and Waledac. [Also this week, Krebs on smart meter hacking.]

The ever growing storage device capacity poses a severe limit to the standard digital forensics collection procedures based on duplicating the original storage device by creating a bit-by-bit copy. Such a traditional procedure is followed, even if the goal of the investigation is to find a limited quantity of digital objects to support or refute an investigative hypothesis related to a precise case category. Therefore, in this paper, we propose a new methodology to deal with data leak cases, by applying an intelligent collection paradigm, a fast analysis approach that reduces investigation time.

Security researchers from Trusteer have shared details on a recently discovered Remote Access Trojan (RAT) attack designed to steal credit card details from hotel point of sale computer systems.

Targeting the hospitality industry has its benefits, as a successful infection could yield information on many individuals, making it much more lucrative for the attackers over a typical infection of a personal system, which Trusteer says typically exposes 1-2 accounts.

The future Internet is an IPv6 network interconnecting traditional computers and a large number of smart objects. This Internet of Things (IoT) will be the foundation of many services and our daily life will depend on its availability and reliable operation. Therefore, among many other issues, the challenge of implementing secure communication in the IoT must be addressed. In the traditional Internet, IPsec is the established and tested way of securing networks. It is therefore reasonable to explore the option of using IPsec as a security mechanism for the IoT.

It’s estimated that more than 50 million people have used public cloud storage services such as Dropbox to share and exchange files. These services make it easy to share and store data but they also create a new security challenge that often clash with existing IT data policies. We’ll discuss:

  • The security challenges of storing data in the cloud
  • Limitations of a digital “do-it-yourself” approach
  • Three simple steps to protecting data in the cloud

Information/secret leaking cannot always be recorded in digital log files. In other words, in log files, not all information/events are recorded, and it is thus impossible to trace the paths of secret leaking on the basis of log files alone. In this paper, to resolve the difficulty of the lack of information, we utilize user–relationship graphs, or social networks, to compensate for the required information. We also utilize a probabilistic analysis to build virtual links to follow information flows. User–relationship graphs are constructed from several flow-net data structures over a longer period so that we can avoid missing embedded threats such as hostile codes. We call this approach virtual flow-net.

As the conflict in Syria persists, the Internet continues to play an interesting role. As we reported in a previous post, there have been targeted attacks against Syrian opposition supporters. With activists’ continued use of social media, it is not surprising to read reports of targeted phishing attempts to steal Facebook and YouTube credentials. A CNN report also revealed that a malware was being propagated through Skype, which brings us to another Skype-themed attack that we have uncovered.
