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.

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 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. First, we provide a brief definition and history of ransomware. Second, we look at the history of hospitals as ransomware targets. Third, we offer a description of the WannaCry virus, what is known about its development, method of action, and those who are believed to have deployed it; in this section, we also discuss methods to defend against this particular virus. 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.
