This paper contains an analysis of the payload of the popular ransomware for Windows, Android, Linux, and MacOSX platforms. Namely, VaultCrypt (CrypVault), TeslaCrypt, NanoLocker, Trojan-Ransom.Linux.Cryptor, Android Simplelocker, OSX/KeRanger-A, WannaCry, Petya, NotPetya, Cerber, Spora, Serpent ransomware were put under the microscope. A set of characteristics was proposed to be used for the analysis...
This paper addresses the problem of incident response in clouds. A conventional incident response model is formulated to be used as a basement for the cloud incident response model. Minimization of incident handling time is considered as a key criterion of the proposed cloud incident response model that can be done at the expense of embedding infrastructure redundancy into the cloud infrastructure...
This paper addresses the problem of protecting cloud environments against targeted attacks, which have become a popular mean of gaining access to organization's confidential information and resources of cloud providers. Only in 2015 eleven targeted attacks have been discovered by Kaspersky Lab. One of them — Duqu2 — successfully attacked the Lab itself. In this context, security researchers show rising...
In this paper it is proposed an universal criterion and structures for evaluating the quality of object interaction in the deterministic cyberspace through the use of only the logical operations to determine the distances between the processes and phenomena by developing high-performance parallel processors, focused on effective solving the problems of searching, pattern recognition and decision-making.
Botnets became the powerful cyber weapon that involves tens of millions of infected computers - “cyber zombies” - all over the world. The security industry makes efforts to prevent spreading botnets and compromising an Individual Cyberspace (IC)[1] of users in such way. However, botnets continue existing despite numerous takedowns initiated by antivirus companies, Microsoft, FBI, Europol and others.
Transaction level model of embedded processor for improving the performance of logical relation analysis are proposed. It is based on the hardware implementation of vector operations. There are examples of the model using for the semantics analysis of Russian adjectives. The embedded processor was designed to be part of SoC that will be implemented on FPGA.
This paper describes a security model for protection of individual cyberspace (ICS) as a way of ensuring a secured user's virtual environment. A concept of cyberspace and its main definitions is determined, as well as a formal model that describes mapping of prototypes in cyberspace into real-world objects. Based on analysis of contemporary security threats and methods of protection against them basic...
This paper describes a problem of trust in hardware that can be compromised by means of malicious inclusions called Hardware Trojans. The Hardware Trojans can be embedded in safety critical, security and military systems, such as weapon control systems, battlefield communication systems, information collection and decision making systems, satellite electronics, banking systems, cryptosystems, etc...
