iot malware threats explained and explore case study

In addition, the extraction of dynamic features is more time consuming than the retrieval of static features due to the fact that the sample must be executed for a short period of time. To emulate an architecture, it has to be supported by QEMU, and a guest domain in an eXtensible Markup Language (XML) must be defined. Oldies but goodies. As can be seen, there are different clusters formed mainly of samples from the same family. In one case study, Cylance relays this statement from Taylor Lehmann, CISO of Wellforce, regarding endpoint security: Endpoints and endpoint security are where all the action is…It’s the things that happen on those devices that need the most amount of focus if you want to disrupt an attack, even a sophisticated attack. Nobody knows for sure how much time passes from the moment an IoT device becomes a bot until the time it is used in an attack. Table 1 shows an example of a run sequence and the syscall data. The authors studied the timeline of events related to each family as well as the most relevant vulnerabilities used by them. [15] presented a framework for analyzing and classifying malware in the IoT. Then, it uses the deployment module to check whether the architecture of the analyzed file is supported, that is, whether there is a virtual machine that supports that architecture, and if it is, it starts the virtual machine instance. eHealth is a good example of this circumstance: metrics such as heart rate, blood pressure, or oxygen levels were only stored in special facilities such as hospitals or medical centers and were only available to restricted personnel. With the complexities of IoT security presenting a challenge, and with a security skillset as a resource being hard to find, companies can explore secure software libraries as a security option. Abstract. They statically and dynamically analyzed more than 10,000 samples distributed among the main architectures, namely, ARM, PowerPC, and MIPS, among others. Smart houses, eHealth, or smart cities are just a few examples of contexts that have their origin in the application of the IoT. The main advantage is that static characteristics are quick to extract automatically. Kumar et al. Low-interaction honeypots. This function is formalized as follows: For example, let us consider two executables with five and seven functions, the first with cyclomatic complexities 3, 5, 3, 7, and 4 and the second with complexities, 3, 3, 6, 6, 4, 5, and 2. Although the proposal is designed for malware analysis purposes, it is valid for clustering other types of executables. Years ago, digital interaction between an individual and technology was in general only through a computer. Ostensibly, this makes the devices easier for them to support. The sample will be added to the cluster in which the most similar sample is located. In addition, if a sample is compiled in a static way and another in a dynamic way, there will not be a structural similarity between them (those compiled with static linking have imported library functions within the executable instead of being resolved at runtime as in binaries compiled with dynamic linking). Chang et al. To calculate the similarity, the module uses the following approaches: Dynamic approach. Therefore, there was a huge underestimation of the requirements that these devices and the information that they handle demand. The Malware Threat Landscape. We use the n-grams of the operation codes extracted in the static analysis process. The first sample has two functions with cyclomatic complexity 3, one with 5, one with 7, and another with 4. Given the security vulnerabilities in In this field, the characteristics are divided into the following categories: Static features: here, the focus is on the analysis of the intrinsic characteristics of a binary file without executing its code in the system. 83. This, my friends, is an IoT malware attack waiting to happen. When attacking, the Mirai CNC server instructs all the bots under its command to launch a flood of various kinds of traffic, overwhelming the target host. Having information about how a sample interacts with the compromised device, and what actions it carries out, allows investigators to protect the device or, at least, limit its expansion over the network. Alhanahnah et al. Finally, we used our framework to analyze all the samples and visualize the relationships between them according to the metrics described in Section 3.4.
