The Confessions of the Hacker Who Saved the Internet about:reader?url=https://www.wired.com/story/confessions-marcus-hutc... wired.com The Confessions of the Hacker Who Saved the Internet Andy Greenberg 72-92 minutes At around 7 am on a quiet Wednesday in August 2017, Marcus Hutchins walked out the front door of the Airbnb mansion in Las Vegas where he had been partying for the past week and a half. A gangly, 6'4", 23-year-old hacker with an explosion of blond-brown curls, Hutchins had emerged to retrieve his order of a Big Mac and fries from an Uber Eats deliveryman. But as he stood barefoot on the mansion's driveway wearing only a T-shirt and jeans, Hutchins noticed a black SUV parked on the street—one that looked very much like an FBI stakeout. He stared at the vehicle blankly, his mind still hazed from sleep deprivation and stoned from the legalized Nevada weed he'd been smoking all night. For a fleeting moment, he wondered: Is this finally it? 1 of 51 5/21/2020, 10:07 AM The Confessions of the Hacker Who Saved the Internet about:reader?url=https://www.wired.com/story/confessions-marcus-hutc... June 2020. Subscribe to WIRED . Photograph: Ramona Rosales But as soon as the thought surfaced, he dismissed it. The FBI would never be so obvious, he told himself. His feet had begun to scald on the griddle of the driveway. So he grabbed the McDonald's bag and headed back inside, through the mansion's courtyard, and into the pool house he'd been using as a bedroom. -
Can We Trust Cryptographic Software? Cryptographic Flaws in GNU Privacy Guard V1.2.3
Can We Trust Cryptographic Software? Cryptographic Flaws in GNU Privacy Guard v1.2.3 Phong Q. Nguyen CNRS/Ecole´ normale sup´erieure D´epartement d’informatique 45 rue d’Ulm, 75230 Paris Cedex 05, France. [email protected] http://www.di.ens.fr/˜pnguyen Abstract. More and more software use cryptography. But how can one know if what is implemented is good cryptography? For proprietary soft- ware, one cannot say much unless one proceeds to reverse-engineering, and history tends to show that bad cryptography is much more frequent than good cryptography there. Open source software thus sounds like a good solution, but the fact that a source code can be read does not imply that it is actually read, especially by cryptography experts. In this paper, we illustrate this point by examining the case of a basic In- ternet application of cryptography: secure email. We analyze parts of thesourcecodeofthelatestversionofGNUPrivacyGuard(GnuPGor GPG), a free open source alternative to the famous PGP software, com- pliant with the OpenPGP standard, and included in most GNU/Linux distributions such as Debian, MandrakeSoft, Red Hat and SuSE. We ob- serve several cryptographic flaws in GPG v1.2.3. The most serious flaw has been present in GPG for almost four years: we show that as soon as one (GPG-generated) ElGamal signature of an arbitrary message is released, one can recover the signer’s private key in less than a second on a PC. As a consequence, ElGamal signatures and the so-called ElGamal sign+encrypt keys have recently been removed from GPG. -
North Korean Cyber Capabilities: in Brief
North Korean Cyber Capabilities: In Brief Emma Chanlett-Avery Specialist in Asian Affairs Liana W. Rosen Specialist in International Crime and Narcotics John W. Rollins Specialist in Terrorism and National Security Catherine A. Theohary Specialist in National Security Policy, Cyber and Information Operations August 3, 2017 Congressional Research Service 7-5700 www.crs.gov R44912 North Korean Cyber Capabilities: In Brief Overview As North Korea has accelerated its missile and nuclear programs in spite of international sanctions, Congress and the Trump Administration have elevated North Korea to a top U.S. foreign policy priority. Legislation such as the North Korea Sanctions and Policy Enhancement Act of 2016 (P.L. 114-122) and international sanctions imposed by the United Nations Security Council have focused on North Korea’s WMD and ballistic missile programs and human rights abuses. According to some experts, another threat is emerging from North Korea: an ambitious and well-resourced cyber program. North Korea’s cyberattacks have the potential not only to disrupt international commerce, but to direct resources to its clandestine weapons and delivery system programs, potentially enhancing its ability to evade international sanctions. As Congress addresses the multitude of threats emanating from North Korea, it may need to consider responses to the cyber aspect of North Korea’s repertoire. This would likely involve multiple committees, some of which operate in a classified setting. This report will provide a brief summary of what unclassified open-source reporting has revealed about the secretive program, introduce four case studies in which North Korean operators are suspected of having perpetrated malicious operations, and provide an overview of the international finance messaging service that these hackers may be exploiting. -

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. -

Westlaw Journal BANK & LENDER LIABILITY Litigation News and Analysis • Legislation • Regulation • Expert Commentary VOLUME 17, ISSUE 6 / AUGUST 1, 2011 Expert Analysis Once More Into the Breach: Are We Learning Anything? By Cynthia Larose, Esq. Mintz Levin Cohn Ferris Glovsky & Popeo I’m a guy who doesn’t see anything good having come from the Internet. … [The Internet] created this notion that anyone can have whatever they want at any given time. It’s as if the stores on Madison Avenue were open 24 hours a day. They feel entitled. They say, “Give it to me now,” and if you don’t give it to them for free, they’ll steal it. –Sony Pictures Entertainment CEO Michael Lynton, May 14, 20091 How ironic. This comment two years ago by Lynton created a minor firestorm and drove him to post a lengthy rebuttal on The Huffington Post,2 but at the time, Lynton was referring to content piracy, not data breaches. Given the events since Sony’s massive data breaches in April3 (and subsequent breaches in May and June), he might as well as have been referring to user informa- tion held by Sony and its various properties. As a matter of fact, the Sony Pictures hackers said, “Sony stored over 1 million passwords of its customers in plain text, which means it’s just a matter of taking it.”4 Since the April PlayStation Network breach that exposed more than 100 million user accounts, Sony has been hacked more than 10 times. Sony Europe,5 Sony BMG Greece,6 Sony Thailand,7 Sony Music Japan8 and Sony Ericsson Canada9 all suffered some intrusion and compromise of user information. -

Lawyer: British Hacking Suspect Will Be Vindicated 14 August 2017
Lawyer: British hacking suspect will be vindicated 14 August 2017 "Marcus Hutchins is a brilliant young man and a hero," said Marcia Hofmann, an attorney affiliated with the Electronic Frontier Foundation, a digital rights group, who represented Hutchins at the hearing. "He is going to vigorously defend himself against these charges. And when the evidence comes to light, we are confident he will be fully vindicated." Hours after the hearing, Hutchins resumed activity on Twitter. "I'm still on trial, still not allowed to go home, still on house arrest; but now i am allowed online," he wrote. He also joked about the experience with a sarcastic Marcus Hutchins (R), the British cyber security expert "to do" list from his US visit: "Things to do during accused of creating and selling malware that steals defcon: Attend parties.
