Download or read book Wannacry Ransomware and the Emerging Threat to Corporations written by Lawrence J. Trautman and published by . This book was released on 2019 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The WannaCry ransomware attack began on May 12, 2017, and is unprecedented in scale--quickly impacting nearly a quarter-million computers in over 150 countries. The WannaCry virus exploits a vulnerability to Microsoft Windows that was originally developed by the U.S. National Security Agency and operates by encrypting a victim's data and demanding payment of a ransom in exchange for data recovery. Security experts have indicated that a North Korea-linked group of hackers--who have also been implicated in cyberattacks against Sony Pictures in 2014, the Bangladeshi Central Bank in 2016, and Polish banks in February 2017--is behind the attack. Ransomware threatens institutions worldwide, but the risks for businesses are all the starker--potentially catastrophic. This article provides corporate executives with much of what they need to know about the evolving threats of malware and ransomware like Cryptolocker, Kelihos Botnet, Locky, Nymain, Petya, NotPetya, and WannaCry.

Fourth, we discuss the Petya and NotPetya attacks. Fifth, is a discussion of municipal ransomware attacks. Sixth, we review the myriad and unique risks that ransomware poses for corporations--including expected refinements of the technique, such as to effect corporate sabotage. Seventh, we discuss the duties and responsibilities of corporate directors and the Ormerod-Trautman data security economic model. Eighth and finally, we review the current cybersecurity legal landscape with a particular focus on corporate best practices and how business executives protect themselves against cybersecurity-related liability. We believe this Article contributes to the sparse existing literature about ransomware and related cyber threats posed to corporate boards and management.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book explores a special species of trouble afflicting modern societies: creeping crises. These crises evolve over time, reveal themselves in different ways, and resist comprehensive responses despite periodic public attention. As a result, these crises continue to creep in front of our eyes. This book begins by defining the concept of a creeping crisis, showing how existing literature fails to properly define and explore this phenomenon and outlining the challenges such crises pose to practitioners. Drawing on ongoing research, this book presents a diverse set of case studies on: antimicrobial resistance, climate change-induced migration, energy extraction, big data, Covid-19, migration, foreign fighters, and cyberattacks. Each chapter explores how creeping crises come into existence, why they can develop unimpeded, and the consequences they bring in terms of damage and legitimacy loss. The book provides a proof-of-concept to help launch the systematic study of creeping crises. Our analysis helps academics understand a new species of threat and practitioners recognize and prepare for creeping crises.

This book was released on 2018-01-18 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cybersecurity-a concept we hear mentioned frequently, especially in this period of rapidly emerging threats-is an ever-evolving concept. Maintaining an effective cybersecurity posture requires constant vigilance as new threats emerge and old ones return. Too often, however, when we hear about the importance of cybersecurity, we are left without concrete steps to take to ensure our systems are best positioned to defend against emerging threats. One of the goals of today's hearing is to learn about real, tangible measures the government can take to ensure its IT security systems are appropriately reinforced to defend against new and emerging threats, including novel and sophisticated ransomware threats. The specific focus of today's hearing will be the recent WannaCry ransomware attack, a new type of ransomware infection, which affected over one million unique systems last month in a worldwide attack that impacted nearly every country in the world. Although the concept of ransomware is not new, the type of ransomware employed by WannaCry was novel. WannaCry worked by encrypting documents on a computer, instructing victims to pay $300 in Bitcoin in order to regain access to their user's documents. Unlike typical forms of ransomware, however, WannaCry signaled the ushering in of a new type of worming ransomware, which caused the attack to spread faster and more rapidly with each new infection. In light of the novelty built into WannaCry's method of attack, cybersecurity experts, including those we will hear from today, have expressed significant concerns that WannaCry is only a preview of a more sophisticated ransomware infection that many believe will inevitably be launched by hackers in the near future.

Download or read book Privileged Attack Vectors written by Morey J. Haber and published by Apress. This book was released on 2020-06-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: See how privileges, insecure passwords, administrative rights, and remote access can be combined as an attack vector to breach any organization. Cyber attacks continue to increase in volume and sophistication. It is not a matter of if, but when, your organization will be breached. Threat actors target the path of least resistance: users and their privileges. In decades past, an entire enterprise might be sufficiently managed through just a handful of credentials. Today’s environmental complexity has seen an explosion of privileged credentials for many different account types such as domain and local administrators, operating systems (Windows, Unix, Linux, macOS, etc.), directory services, databases, applications, cloud instances, networking hardware, Internet of Things (IoT), social media, and so many more. When unmanaged, these privileged credentials pose a significant threat from external hackers and insider threats. We are experiencing an expanding universe of privileged accounts almost everywhere. There is no one solution or strategy to provide the protection you need against all vectors and stages of an attack. And while some new and innovative products will help protect against or detect against a privilege attack, they are not guaranteed to stop 100% of malicious activity. The volume and frequency of privilege-based attacks continues to increase and test the limits of existing security controls and solution implementations. Privileged Attack Vectors details the risks associated with poor privilege management, the techniques that threat actors leverage, and the defensive measures that organizations should adopt to protect against an incident, protect against lateral movement, and improve the ability to detect malicious activity due to the inappropriate usage of privileged credentials. This revised and expanded second edition covers new attack vectors, has updated definitions for privileged access management (PAM), new strategies for defense, tested empirical steps for a successful implementation, and includes new disciplines for least privilege endpoint management and privileged remote access. What You Will Learn Know how identities, accounts, credentials, passwords, and exploits can be leveraged to escalate privileges during an attack Implement defensive and monitoring strategies to mitigate privilege threats and risk Understand a 10-step universal privilege management implementation plan to guide you through a successful privilege access management journeyDevelop a comprehensive model for documenting risk, compliance, and reporting based on privilege session activity Who This Book Is For Security management professionals, new security professionals, and auditors looking to understand and solve privilege access management problems
