  • 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.

As we create and expand more and more data within our interconnected electronic universe, the threat that they bring to its fragile structure grows as well. However Anonymous is not the only group of hackers/activists or hacktivists that have made their presence known. LulzSec was a group that wreaked havoc with information systems in 2011. This will be a case study examination of their activities so that a better understanding of five aspects can be obtained: the Timeline of activities, the Targets of attack, the Tactics the group used, the makeup of the Team and a category which will be referred to as The Twist for reasons which will be made clear at the end of the paper. Keywords: LulzSec, Hackers, Security, AntiSec, Anonymous, Sabu INTRODUCTION Information systems lie at the heart of our modern existence. We deal with them when we work, when we play and when we relax; texting, checking email, posting on Facebook, Tweeting, gaming, conducting e-commerce and e- banking have become so commonplace as to be nearly invisible in modern life. Yet, within each of these electronic interactions lies the danger that the perceived line of security and privacy might be breached and our most important information and secrets might be revealed and exploited.

  • 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.

  • Risk Report Back in October 2016, Dyn Encountered a Massive DNS Ddos Attack That Knocked
    Dyn DNS Cyberattack By Bryce Kolton 12/7/2016 | INFO 312 Introduction On October 21st 2016, a terabit sized attack took down internet connectivity for users across the globe. Over three waves, millions of users were interrupted during main business hours. The attack targeted Dyn (pronounced “dine”), a company that in part provides Domain Name Service registration for websites. Companies affected included Amazon, BBC, CNN, Comcast, Fox, GitHub, Netflix, PayPal, Reddit, Starbucks, Twitter, Verizon, Visa, Wikia and hundreds more. Credit card terminals were inoperative, news sites unavailable, and users unable to reach some of the internet’s most popular websites. The internet ground to a halt for several hours, with major Fortune 500 companies among those affected. The focus of this risk management report will be the cyberattack at large; The background, causes, previous mitigations, response, still present risks, and recommendations after one of the largest cyberattacks ever recorded. Understanding the Domain Name Service As an illustrative example, let’s say you want to visit a new grocery store your friend just told you about, “Sya’s Grocery.” You know the name, but you need to find the physical address. By using a service like Google Maps, you can transcribe the human-readable name into the destination. The Domain Name Service works much the same way, but for URLs. When you type in “google.com,” your computer is clueless to the ‘real address’ it’s supposed to go to. That’s where DNS steps in: your device asks its closes DNS server “Who is ‘google.com’?” If the server doesn’t know, it’ll pass the request along until it finds a server that does.

USA TODAY SAN FRANCISCO — At least two successive waves of online attacks blocked multiple major websites Friday, at times making it impossible for many users on the East Coast to access Twitter, Spotify, Netflix, Amazon, Tumblr and Reddit. The first attacks appear to have begun around 7:10 am Friday, then resolved towards 9:30 am, but then a fresh wave began. The cause was a large-scale distributed denial of service attack (DDoS) against Internet performance company Dyn that blocked user access to many popular sites standstill. Dyn reported the sites going down at around 11:10 a.m. UTC, or roughly 7:10 a.m. ET, posting on its website that it "began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure." In an update posted at 8:45 a.m. ET, the company confirmed the attack, noting that "this attack is mainly impacting US East and is impacting Managed DNS customers in this region. Our Engineers are continuing to work on mitigating this issue." White House Press Secretary Josh Earnest said the Department of Homeland Security was “monitoring the situation" but that “at this point I don’t have any information about who may be responsible for this malicious activity.” It was unclear Friday if the attacks are focused on Dyn specifically or companies that it provides services to, said Carl Herberger, vice president of security at security company Radware.
