RSA-512 Certificates Abused in the Wild
RSA-512 Certificates abused in the wild During recent weeks we have observed several interesting publications which have a direct relation to an investigation we worked on recently. On one hand there was a Certificate Authority being revoked by Mozilla, Microsoft and Google (Chrome), on the other hand there was the disclosure of a malware attack by Mikko Hypponen (FSecure) using a government issued certificate signed by the same Certificate Authority. That case however is not self-contained and a whole range of malicious software had been signed with valid certificates. The malicious software involved was used in targeted attacks focused on governments, political organizations and the defense industry. The big question is of course, what happened, and how did the attackers obtain access to these certificates? We will explain here in detail how the attackers have used known techniques to bypass the Microsoft Windows code signing security model. Recently Mikko Hypponen wrote a blog on the F-Secure weblog (http://www.f-secure.com/weblog/archives/00002269.html) detailing the discovery of a certificate used to sign in the wild malware. Specifically this malware was embedded in a PDF exploit and shipped in August 2011. Initially Mikko also believed the certificate was stolen, as that is very common in these days, with a large amount of malware families having support, or optional support, for stealing certificates from the infected system. Apparently someone Mikko spoke to mentioned something along the lines that it had been stolen a long time ago. During the GovCert.nl symposium Mikko mentioned the certificate again, but now he mentioned that according to the people involved with investigating the case in Malaysia it likely wasn't stolen. -

https://doi.org/10.48009/1_iis_2012_133-143 Issues in Information Systems Volume 13, Issue 1, pp. 133-143, 2012 HACKERS GONE WILD: THE 2011 SPRING BREAK OF LULZSEC Stan Pendergrass, Robert Morris University, [email protected] ABSTRACT Computer hackers, like the group known as Anonymous, have made themselves more and more relevant to our modern life. 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. -

Reporting, and General Mentions Seem to Be in Decline
CYBER THREAT ANALYSIS Return to Normalcy: False Flags and the Decline of International Hacktivism By Insikt Group® CTA-2019-0821 CYBER THREAT ANALYSIS Groups with the trappings of hacktivism have recently dumped Russian and Iranian state security organization records online, although neither have proclaimed themselves to be hacktivists. In addition, hacktivism has taken a back seat in news reporting, and general mentions seem to be in decline. Insikt Group utilized the Recorded FutureⓇ Platform and reports of historical hacktivism events to analyze the shifting targets and players in the hacktivism space. The target audience of this research includes security practitioners whose enterprises may be targets for hacktivism. Executive Summary Hacktivism often brings to mind a loose collective of individuals globally that band together to achieve a common goal. However, Insikt Group research demonstrates that this is a misleading assumption; the hacktivist landscape has consistently included actors reacting to regional events, and has also involved states operating under the guise of hacktivism to achieve geopolitical goals. In the last 10 years, the number of large-scale, international hacking operations most commonly associated with hacktivism has risen astronomically, only to fall off just as dramatically after 2015 and 2016. This constitutes a return to normalcy, in which hacktivist groups are usually small sets of regional actors targeting specific organizations to protest regional events, or nation-state groups operating under the guise of hacktivism. Attack vectors used by hacktivist groups have remained largely consistent from 2010 to 2019, and tooling has assisted actors to conduct larger-scale attacks. However, company defenses have also become significantly better in the last decade, which has likely contributed to the decline in successful hacktivist operations. -
SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell Secureworks Counter Threat Unit℠ Threat Intelligence
SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell SecureWorks Counter Threat Unit℠ Threat Intelligence Presented at Black Hat Europe – March 14, 2012. Introduction Secure Sockets Layer (SSL) [1] and its successor Transport Layer Security (TLS) [2] have become key components of the modern Internet. The privacy, integrity, and authenticity [3] [4] provided by these protocols are critical to allowing sensitive communications to occur. Without these systems, e- commerce, online banking, and business-to-business exchange of information would likely be far less frequent. Threat actors have also recognized the benefits of transport security, and they are increasingly turning to SSL to hide their activities. Advanced Persistent Threat (APT) attackers [5], botnets [6], and even commodity web attacks can leverage SSL encryption to evade detection. To counter these tactics, organizations are increasingly deploying security controls that intercept end- to-end encrypted channels. Web proxies, data loss prevention (DLP) systems, specialized threat detection solutions, and network intrusion prevention systems (NIPS) offer functionality to intercept, inspect, and filter encrypted traffic. Similar functionality is present in lawful intercept systems and solutions enabling the broad surveillance of encrypted communications by governments. Broadly classified as “SSL/TLS interception proxies,” these solutions act as a “man in the middle,” violating the end-to-end security promises of SSL. This type of interception comes at a cost. Intercepting SSL-encrypted connections sacrifices a degree of privacy and integrity for the benefit of content inspection, often at the risk of authenticity and endpoint validation. Implementers and designers of SSL interception proxies should consider these risks and understand how their systems operate in unusual circumstances. -

Legal Checks on Surveillance and Modern Modes of Warfare William Howell (University of Chicago) and Mariah Zeisberg (University of Michigan)
Legal Checks on Surveillance and Modern Modes of Warfare William Howell (University of Chicago) and Mariah Zeisberg (University of Michigan) (This essay appeared in the Boston Review earlier this summer.) As the Obama era comes to a close, two antithetical visions of our government appear before us. On the first, executive power on domestic issues is not merely contained; it is subdued. A curious blend of congressional initiative and intransigence render a domesticated presidency. But we also have caught glimpses of an enormous and largely clandestine national security apparatus. Whereas the president’s ambitions for domestic policymaking are checked fiercely and ceaselessly, Congress either affirmatively protects or passively cedes vast discretionary power to the president on matters of national security. What explains this disparity, and what can be done about it? In particular, can the formal tools of policy oversight meaningfully constrain the creeping power of the surveillance state or modern ways of warfare? Most constitutional law scholars think so. Through investigations, hearings, audits, and publicity, they argue, Congress and the courts can check executive secrecy. These scholars are not entirely wrong, but their hopes are exaggerated. Traditional legal reasoning, preoccupied with political checks, has an impoverished view of the nature of modern surveillance and obscures the generative forces behind various forms of public and private resistance to state surveillance. • • • A recent argument on this score, and one that reflects many of characteristic features of current legal reasoning, can be found in University of Minnesota law professor Heidi Kitrosser’s new book Reclaiming Accountability. Kitrosser recommends that we recommit ourselves to the basic constitutional framework for limiting presidential war powers. -
Security Economics in the HTTPS Value Chain
Security Economics in the HTTPS Value Chain Hadi Asghari*, Michel J.G. van Eeten*, Axel M. Arnbak+ & Nico A.N.M. van Eijk+1 * [email protected], [email protected] Delft University of Technology, Faculty of Technology Policy and Management + [email protected], [email protected] University van Amsterdam, Faculty of Law, Institute for Information Law Abstract. Even though we increasingly rely on HTTPS to secure Internet communications, several landmark incidents in recent years have illustrated that its security is deeply flawed. We present an extensive multi-disciplinary analysis that examines how the systemic vulnerabilities of the HTTPS authentication model could be addressed. We conceptualize the security issues from the perspective of the HTTPS value chain. We then discuss the breaches at several Certificate Authorities (CAs). Next, we explore the security incentives of CAs via the empirical analysis of the market for SSL certificates, based on the SSL Observatory dataset. This uncovers a surprising pattern: there is no race to the bottom. Rather, we find a highly concentrated market with very large price differences among suppliers and limited price competition. We explain this pattern and explore what it tells us about the security incentives of CAs, including how market leaders seem to benefit from the status quo. In light of these findings, we look at regulatory and technical proposals to address the systemic vulnerabilities in the HTTPS value chain, in particular the EU eSignatures proposal that seeks to strictly regulate HTTPS communications.
