University of Central Florida, 2000 M.S. Florida Institute of Technology, 2008 A dissertation submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the College of Engineering and Computer Science at the University of Central Florida Orlando, Florida Spring Term 2019 Major Professor: Ratan Kumar Guha © 2019 Sharif Hassan ii ABSTRACT In this research we built a custom experimental range using opensource emulated and custom pure honeypots designed to detect or capture attacker activity. The focus is to test the effectiveness of a deception in its ability to evade detection coupled with attacker skill levels. The range consists of three zones accessible via virtual private networking. The first zone houses varying configurations of opensource emulated honeypots, custom built pure honeypots, and real SSH servers. The second zone acts as a point of presence for attackers. The third zone is for administration and monitoring. Using the range, both a control and participant-based experiment were conducted. We conducted control experiments to baseline and empirically explore honeypot detectability amongst other systems through adversarial testing. We executed a series of tests such as network service sweep, enumeration scanning, and finally manual execution. We also selected participants to serve as cyber attackers against the experiment range of varying skills having unique tactics, techniques and procedures in attempting to detect the honeypots. We have concluded the experiments and performed data analysis. We measure the anticipated threat by presenting the Attacker Bias Perception Profile model. Using this model, each participant is ranked based on their overall threat classification and impact. This model is applied to the results of the participants which helps align the threat to likelihood and impact of a honeypot being detected. The results indicate the pure honeypots are significantly difficult to detect. Emulated honeypots are grouped in different categories based on the detection and skills of the attackers. We developed a framework abstracting the deceptive process, the interaction iii with system elements, the use of intelligence, and the relationship with attackers. The framework is illustrated by our experiment case studies and the attacker actions, the effects on the system, and impact to the success. iv I dedicate this dissertation, my research, and all the efforts involved first to my loving wife Kimmy who without her I would not have been able to complete this work. I would also like to dedicate this to my daughters Kinsley and Layla for it was you both who gave me the motivation. Finally, I dedicate this work to Clover for always being by my side. v ACKNOWLEDGMENTS I would first like to express my gratitude to my advisor Dr Ratan Guha for everything you have done.

  • Advanced Persistent Threats
    THREAT RESEARCH Defending Against Advanced Persistent Threats Introduction As the name “Advanced” suggests, APT (advanced persistent threat) is one of the most sophisticated and organized forms of network attacks that keep cybersecurity professionals up at night. Unlike many hit & run traditional cyberattacks, an APT is carried out over a prolonged period of time by skilled threat actors who strategize multi-staged campaigns against their targets, employing clandestine tools & techniques such as Remote Administration Tools (RAT), Toolkits, Backdoor Trojans, Social Engineering, DNS Tunneling etc. These experienced cybercriminals are mostly backed & well-funded by nation states and corporation-backed organizations to specifi cally target high value organizations with the following objectives in mind: a Theft of Intellectual Property & classifi ed data i.e. Cyber Espionage a Access to critical & sensitive communications a Access to credentials of critical systems a Sabotage or exfi ltration of databases a Theft of Personal Identifi able Information (PII) a Access to critical infrastructure to perform internal reconnaissance To achieve the above goals, APT Groups use novel techniques to obfuscate their actions and easily bypass traditional security barriers that are not advancing at the same rate as the sophisticated attack patterns of cybercriminals. To understand the evolved behavioral pattern of APT Groups in the year 2020, a review of their latest activities revealed interesting developments and a few groundbreaking events¹: a Southeast Asia

    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.

  • LAZARUS UNDER the HOOD Executive Summary
    LAZARUS UNDER THE HOOD Executive Summary The Lazarus Group’s activity spans multiple years, going back as far as 2009. Its malware has been found in many serious cyberattacks, such as the massive data leak and file wiper attack on Sony Pictures Entertainment in 2014; the cyberespionage campaign in South Korea, dubbed Operation Troy, in 2013; and Operation DarkSeoul, which attacked South Korean media and financial companies in 2013. There have been several attempts to attribute one of the biggest cyberheists, in Bangladesh in 2016, to Lazarus Group. Researchers discovered a similarity between the backdoor used in Bangladesh and code in one of the Lazarus wiper tools. This was the first attempt to link the attack back to Lazarus. However, as new facts emerged in the media, claiming that there were at least three independent attackers in Bangladesh, any certainty about who exactly attacked the banks systems, and was behind one of the biggest ever bank heists in history, vanished. The only thing that was certain was that Lazarus malware was used in Bangladesh. However, considering that we had previously found Lazarus in dozens of different countries, including multiple infections in Bangladesh, this was not very convincing evidence and many security researchers expressed skepticism abound this attribution link. This paper is the result of forensic investigations by Kaspersky Lab at banks in two countries far apart. It reveals new modules used by Lazarus group and strongly links the tools used to attack systems supporting SWIFT to the Lazarus Group’s arsenal of lateral movement tools. Considering that Lazarus Group is still active in various cyberespionage and cybersabotage activities, we have segregated its subdivision focusing on attacks on banks and financial manipulations into a separate group which we call Bluenoroff (after one of the tools they used).

(2) Targeted restrictive measures against cyber-attacks with a significant effect which constitute an external threat to the Union or its Member States are among the measures included in the Union’s framework for a joint diplomatic response to malicious cyber-activities (the cyber diplomacy toolbox) and are a vital instrument to deter and respond to such activities. Restrictive measures can also be applied in response to cyber-attacks with a significant effect against third States or international organisations, where deemed necessary to achieve common foreign and security policy objectives set out in the relevant provisions of Article 21 of the Treaty on European Union. (3) On 16 April 2018 the Council adopted conclusions in which it firmly condemned the malicious use of information and communications technologies, including in the cyber-attacks publicly known as ‘WannaCry’ and ‘NotPetya’, which caused significant damage and economic loss in the Union and beyond. On 4 October 2018 the Presidents of the European Council and of the European Commission and the High Representative of the Union for Foreign Affairs and Security Policy (the ‘High Representative’) expressed serious concerns in a joint statement about an attempted cyber-attack to undermine the integrity of the Organisation for the Prohibition of Chemical Weapons (OPCW) in the Netherlands, an aggressive act which demonstrated contempt for the solemn purpose of the OPCW.

  • Gothic Panda Possibly Used Doublepulsar a Year Before The
    Memo 17/05/2019 - TLP:WHITE Gothic Panda possibly used DoublePulsar a year before the Shadow Brokers leak Reference: Memo [190517-1] Date: 17/05/2019 - Version: 1.0 Keywords: APT, DoublePulsar, China, US, Equation Group Sources: Publicly available sources Key Points Gothic Panda may have used an Equation Group tool at least one year before the Shadow Brokers leak. It is unknown how the threat group obtained the tool. This is a good example of a threat actor re-using cyber weapons that were originally fielded by another group. Summary According research conducted by Symantec, the Chinese threat actor known as Gothic Panda (APT3, UPS, SSL Beast, Clandestine Fox, Pirpi, TG-0110, Buckeye, G0022, APT3) had access to at least one NSA-associated Equation Group tool a year before they were leaked by the Shadow Brokers threat actor. On April 14, 2017, a threat actor called the Shadow Brokers released a bundle of cyber-attack tools purportedly coming from the US NSA, also referred to as the Equation Group. Among the released material there was the DoublePulsar backdoor implant tool, which was used alongside EternalBlue in the May 2017 destructive WannaCry attack. DoublePulsar is a memory-based kernel malware that allows perpetrators to run arbitrary shellcode payloads on the target system. It does not write anything on the hard drive and will thus disappear once the victim machine is rebooted. Its only purpose is to enable dropping other malware or executables in the system. According to Symantec, Gothic Panda used the DoublePulsar exploit as early as in 2016, a full year before the Shadow Brokers release.

  • 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.

    KIVU THREAT INTELLIGENCE Cyber Threat Intelligence Insights for Claims and Underwriting Professionals Volume XIX-1 February 1, 2019 Purpose To share cyber threat intelligence and aid in Kivu Myth Busters: Ryuk vs. North Korea protecting digital assets globally I. Executive Summary Sources Several media outlets misleadingly This publication incorporates reported that the Ryuk ransomware publicly-available and Kivu variant may have been developed and internally-developed Cyber Threat Intelligence operated by North Korean state- sponsored actors. Kivu conducted its own proprietary and confidential analysis of Subscription/Questions the malware variant and concludes with Click HERE to request being a high degree of confidence that the added to this product’s Ryuk (aka Hermes v2.1) ransomware distribution list variant was not developed by North Korean state-sponsored actors and that Ryuk usage by itself is not indicative of North Korea being behind a particular attack. II. Background Over the last few years, North Korea has continued to develop its Cyber Operations capabilities, and currently has an army of approximately 6,000 hackers, some of which were trained in Russia and China1. Unlike typical state-sponsored cyber operations programs that generally focus on intelligence gathering, influence and/or information operations and offensive capabilities, the North Korean regime also dedicates significant amount of resources toward operations for financial gain. According to research by The New York Times, North Korea’s for-profit cyber operations may earn over US$1 billion a year for the regime, which would account for roughly 1/3rd of North Korea’s annual exports2. While North Korea was able to pull off several successful cyber-heists, the primary Contact Us goal of this report is to examine whether the Ryuk (aka Hermes v2.1) ransomware www.kivuconsulting.com variant has been improperly attributed to this regime.
