  • Protecting Sensitive and Personal Information from Ransomware-Caused Data Breaches
    Protecting Sensitive and Personal Information from Ransomware-Caused Data Breaches OVERVIEW Over the past several years, the Cybersecurity and Infrastructure Security Ransomware is a serious and increasing threat to all government and Agency (CISA) and our partners have responded to a significant number of private sector organizations, including ransomware incidents, including recent attacks against a U.S. pipeline critical infrastructure organizations. In company and a U.S. software company, which affected managed service response, the U.S. government providers (MSPs) and their downstream customers. launched StopRansomware.gov, a centralized, whole-of-government Ransomware is malware designed to encrypt files on a device, rendering webpage providing ransomware files and the systems that rely on them unusable. Traditionally, malicious resources, guidance, and alerts. actors demand ransom in exchange for decryption. Over time, malicious actors have adjusted their ransomware tactics to be more destructive and impactful. Malicious actors increasingly exfiltrate data and then threaten to sell or leak it—including sensitive or personal information—if the ransom is not paid. These data breaches can cause financial loss to the victim organization and erode customer trust. All organizations are at risk of falling victim to a ransomware incident and are responsible for protecting sensitive and personal data stored on their systems. This fact sheet provides information for all government and private sector organizations, including critical infrastructure organizations, on preventing and responding to ransomware-caused data breaches. CISA encourages organizations to adopt a heightened state of awareness and implement the recommendations below. PREVENTING RANSOMWARE ATTACKS 1. Maintain offline, encrypted backups of data and regularly test your backups.

  • About the Sony Hack
    All About the Sony Hack Sony Pictures Entertainment was hacked in late November by a group called the Guardians of Peace. The hackers stole a significant amount of data off of Sony’s servers, including employee conversations through email and other documents, executive salaries, and copies of unreleased January/February 2015 Sony movies. Sony’s network was down for a few days as administrators worked to assess the damage. According to the FBI, the hackers are believed have ties with the North Korean government, which has denied any involvement with the hack and has even offered to help the United States discover the identities of the hackers. Various analysts and security experts have stated that it is unlikely All About the Sony Hack that the North Korean government is involved, claiming that the government likely doesn’t have the Learn how Sony was attacked and infrastructure to succeed in a hack of this magnitude. what the potential ramifications are.

  • The 2014 Sony Hack and the Role of International Law
    The 2014 Sony Hack and the Role of International Law Clare Sullivan* INTRODUCTION 2014 has been dubbed “the year of the hack” because of the number of hacks reported by the U.S. federal government and major U.S. corporations in busi- nesses ranging from retail to banking and communications. According to one report there were 1,541 incidents resulting in the breach of 1,023,108,267 records, a 78 percent increase in the number of personal data records compro- mised compared to 2013.1 However, the 2014 hack of Sony Pictures Entertain- ment Inc. (Sony) was unique in nature and in the way it was orchestrated and its effects. Based in Culver City, California, Sony is the movie making and entertain- ment unit of Sony Corporation of America,2 the U.S. arm of Japanese electron- ics company Sony Corporation.3 The hack, discovered in November 2014, did not follow the usual pattern of hackers attempting illicit activities against a business. It did not specifically target credit card and banking information, nor did the hackers appear to have the usual motive of personal financial gain. The nature of the wrong and the harm inflicted was more wide ranging and their motivation was apparently ideological. Identifying the source and nature of the wrong and harm is crucial for the allocation of legal consequences. Analysis of the wrong and the harm show that the 2014 Sony hack4 was more than a breach of privacy and a criminal act. If, as the United States maintains, the Democratic People’s Republic of Korea (herein- after North Korea) was behind the Sony hack, the incident is governed by international law.

  • The Ultimate Guide to Vendor Data Breach Response
    The Ultimate Guide to Vendor Data Breach Response This paper was authored by Corvus’s VP of Smart Breach Response Lauren Winchester in collaboration with Dominic Paluzzi, Co-Chair of the Data Privacy and Cybersecurity practice at the law firm McDonald Hopkins. Commercial insurance reimagined. The Ultimate Guide to Vendor Data Breach Response Cyber insurance brokers help their clients plan for what happens when they experience a data breach or ransomware incident. Something often overlooked is how that plan may change when the breach is at a vendor and the investigation is outside of their control. Most organizations are in the midst of a decade-old shift to deeper integration with managed service providers, software-as-a-service tools, and other cloud-based software solutions. Having worked with thousands of brokers and policyholders, we’ve observed an unspoken assumption that these vendors, with their highly advanced products, are also par- agons of cybersecurity. That’s a misplaced assumption for three reasons. The bigger and more complex an organization, generally the harder it is to keep safe. Vendors may have excellent security teams and practices, but 1. face a sisyphean task given their scale. The adversarial question. These companies may be at greater risk because criminals see them as a rich target -- if they can infiltrate the vendor, they 2. can potentially extend their attack to hundreds or thousands of customer organizations. Some providers have an air of invincibility about their exposure, likely for the same reason their customers instinctively trust them. A survey by 3. Coveware shows a large disconnect between what MSPs believe to be the cost and consequences of an attack, and what they are in reality.
