Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2023 in the subject Computer Science - IT-Security, grade: A, , language: English, abstract: Ransomware attacks are not a new idea, but their prevalence has risen dramatically in recent times. A key explanation for this is the financial compensation that the perpetrator stands to gain, as well as the fact that crypto-currency allows for anonymous transactions. Initially a single-host menace, ransomware is rapidly developing to conduct more sophisticated attacks by spreading through a network of hosts. One of the most difficult aspects of defending from these attacks is that every ransomware caucus is always evolving, rendering individual samples unidentifiable. Common signature-based countermeasures, such as those used to fight viruses, are made ineffective as a result. Furthermore, attempting to reverse engineer each sample in order to develop successful countermeasures or solutions is an expensive venture. Much more so now that ransomware writers are beginning to use complicated methods ensuring that getting to the original source code more difficult. The researcher believes that a more general detection approach can be used to find a solution. It should be focused on the traits that all ransomware families share. This should help to shift the focus of research from samples to families. I collect meta-data about the files that are read and written during ransomware attacks using easy and fast metrics and applied a qualitative mode of data collection. These attacks have a common pattern of attempting to encrypt all of the victims' data. Encrypted files have a significant increase in entropy while the data size remains relatively unchanged. These characteristics can also be seen in normal user behaviour, such as when a user encrypts a file. As a result, we must allow encryption while also imposing a frequency limit to ensure that regular user traffic does not result in false positives.

Download or read book Emerging Trends in ICT Security written by Leonidas Deligiannidis and published by Elsevier Inc. Chapters. This book was released on 2013-11-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day, people interact with numerous computer systems, networks, and services that require the exchange of sensitive data. However, the Internet is a highly distributed system operated by many different entities and as such should not be trusted by end users. Users, whether consumers or businesses, retain no control over how their information is routed among the many networks that comprise the Internet. Therefore, there is a strong need for cryptographic protocols to authenticate, verify trust, and establish a secure channel for exchanging data. This chapter presents a series of projects and demonstrations for systems and networking professionals who want to increase their comprehension of security concepts and protocols. The material presented here is derived from existing courses taught by the authors in the areas of cryptography, network security, and wireless security.

Download or read book Cybersecurity Issues in Emerging Technologies written by Leandros Maglaras and published by CRC Press. This book was released on 2021-10-15 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threat landscape is evolving with tremendous speed. We are facing an extremely fast-growing attack surface with a diversity of attack vectors, a clear asymmetry between attackers and defenders, billions of connected IoT devices, mostly reactive detection and mitigation approaches, and finally big data challenges. The clear asymmetry of attacks and the enormous amount of data are additional arguments to make it necessary to rethink cybersecurity approaches in terms of reducing the attack surface, to make the attack surface dynamic, to automate the detection, risk assessment, and mitigation, and to investigate the prediction and prevention of attacks with the utilization of emerging technologies like blockchain, artificial intelligence and machine learning. This book contains eleven chapters dealing with different Cybersecurity Issues in Emerging Technologies. The issues that are discussed and analyzed include smart connected cars, unmanned ships, 5G/6G connectivity, blockchain, agile incident response, hardware assisted security, ransomware attacks, hybrid threats and cyber skills gap. Both theoretical analysis and experimental evaluation of state-of-the-art techniques are presented and discussed. Prospective readers can be benefitted in understanding the future implications of novel technologies and proposed security solutions and techniques. Graduate and postgraduate students, research scholars, academics, cybersecurity professionals, and business leaders will find this book useful, which is planned to enlighten both beginners and experienced readers.

Download or read book Ransomware Revealed written by Nihad A. Hassan and published by Apress. This book was released on 2019-11-06 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Know how to mitigate and handle ransomware attacks via the essential cybersecurity training in this book so you can stop attacks before they happen. Learn the types of ransomware, distribution methods, internal structure, families (variants), defense strategies, recovery methods, and legal issues related to reporting ransomware incidents to authorities and other affected parties. This book also teaches you how to develop a ransomware incident response plan to minimize ransomware damage and recover normal operations quickly. Ransomware is a category of malware that can encrypt your computer and mobile device files until you pay a ransom to unlock them. Ransomware attacks are considered the most prevalent cybersecurity threats today—the number of new ransomware variants has grown 30-fold since 2015 and they currently account for roughly 40% of all spam messages. Attacks have increased in occurrence from one every 40 seconds to one every 14 seconds. Government and private corporations are targets. Despite the security controls set by organizations to protect their digital assets, ransomware is still dominating the world of security and will continue to do so in the future. Ransomware Revealed discusses the steps to follow if a ransomware infection occurs, such as how to pay the ransom through anonymous payment methods, perform a backup and restore your affected files, and search online to find a decryption tool to unlock (decrypt) your files for free. Mitigation steps are discussed in depth for both endpoint devices and network systems. What You Will Learn Be aware of how ransomware infects your system Comprehend ransomware components in simple terms Recognize the different types of ransomware familiesIdentify the attack vectors employed by ransomware to infect computer systemsKnow how to prevent ransomware attacks from successfully comprising your system and network (i.e., mitigation strategies) Know what to do if a successful ransomware infection takes place Understand how to pay the ransom as well as the pros and cons of paying Set up a ransomware response plan to recover from such attacks Who This Book Is For Those who do not specialize in the cybersecurity field (but have adequate IT skills) and want to fully understand the anatomy of ransomware threats. Although most of the book's content will be understood by ordinary computer users, it will also prove useful for experienced IT users aiming to understand the ins and outs of ransomware threats without diving deep into the technical jargon of the internal structure of ransomware.

Download or read book Assessing Cyber Security written by Maarten Gehem and published by The Hague Centre for Strategic Studies. This book was released on 2015-04-16 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years, a plethora of reports has emerged that assess the causes, dynamics, and effects of cyber threats. This proliferation of reports is an important sign of the increasing prominence of cyber attacks for organizations, both public and private, and citizens all over the world. In addition, cyber attacks are drawing more and more attention in the media. Such efforts can help to better awareness and understanding of cyber threats and pave the way to improved prevention, mitigation, and resilience. This report aims to help in this task by assessing what we know about cyber security threats based on a review of 70 studies published by public authorities, companies, and research organizations from about 15 countries over the last few years. It answers the following questions: what do we know about the number, origin, and impact of cyber attacks? What are the current and emerging cyber security trends? And how well are we prepared to face these threats?
