  • Bitcoin and the Japanese Retail Investor
    BITCOIN AND THE JAPANESE RETAIL INVESTOR by Maksym Grinenko Graduate Programme for Transcultural Studies eighth generation Heidelberg University A dissertation submitted in fulfllment of the requirements for the degree of Doctor of Philosophy under the supervision of Prof. Dr. Harald Fuess Prof. Dr. Hans Martin Krämer July 29, 2019 Abstract The objective of this research is to examine the Bitcoin rally of 2017 as it occurred in Japan and establish a greater context for why it was the Japanese retail investors that propelled the nation to being the largest trader of the cryptocurrency at the end of the year. This dissertation begins with the examination of the technical and economical properties of Bitcoin by classifying it as fulflling two roles: that of a means of payment and that of an investment commodity. Following that is a description of Bitcoin’s roots and the history of its non-speculative usage. These chapters serve as a base for examin- ing the cryptocurrency’s role in Japan. The third chapter examines the Japanese retail investor and the Japanese retail investment landscape with a focus on the question of the low rates of risk-asset participation in face of a favorable investment environment. Historical context is drawn upon to argue that the present situation, wherein most fnan- cial assets are kept as cash, is rather the result of the historical path dependence than the present-day conditions in which Japanese retail investors operate. The fnal chapter addresses the question of high-risk activities in the form of gambling and margin trading by a group of predominantly middle-aged men and connects this propensity to engage in zero-sum games with Bitcoin’s success in Japan.

    SWITCH-CERT report on the latest IT security and privacy trends May / June 2018 I. Microsoft will never contact you by phone: support scam continues to gain momentum They are certainly nothing new, but are becoming ever more sophisticated, expensive and widespread. What we are talking about are phone calls, usually from an English- speaking person posing as a representative from Microsoft or another well-known ICT company. The caller will use a pretext; for example, that the system of the person being called has reported an error message or that there are problems with the licence agreement. The scammers tell the victim that their Microsoft licence will have to be blocked for security reasons and that, in order to avoid this, they can have the problem fixed on their machine immediately via remote access or purchase a support plan or warranty. To add weight to their arguments, they ask their victim to open Microsoft’s support tool, Event Viewer. This program does, in fact, list error messages in most cases. This list of mundane and harmless error messages gives the phone phishers relevant reasons for obtaining credit card details or payments in another form (e.g. iTunes cards) from the victim. Fraudsters can take it even further with the remote access scenario: the person being called is told to download a remote maintenance program, which gives the criminal unrestricted access to the system – including a backdoor for illegal activities or running SWITCH Security, PO Box, 8021 Zurich +41 44 268 15 40 [email protected] securityblog.switch.ch security.switch.ch 1 © SWITCH 2018 bots.

    LV Geostrategie und Geopolitik Fachbereich 1 49069 Osnabrück Cyberwar Grundlagen-Methoden-Beispiele 27.09.2020 Zusammenfassung Der Cyberwar (Cyberkrieg) ist die kriegerische Auseinandersetzung mit den Mitteln der Informationstechnologie. Dieses Arbeitspapier unternimmt eine aktuelle Bestandsaufnahme und geht auf die theoretischen und praktischen Probleme ein. In der Praxis ist der Cyberwar ein integraler Bestandteil militärischen Handelns, lässt sich jedoch nicht ganz von der Spionage trennen, da das Eindringen in und Aufklären von gegnerischen Systemen wesentlich für das weitere Vorgehen ist. Nach einem Überblick über Angriffsmethoden, Angreifer (Advanced Persistent Threats), Spionagetools, Cyberwaffen und der Cyberverteidigung liegt ein besonderes Augenmerk auf der Einordnung von Cyberangriffen (Attribution) und der Smart Industry (Industrie 4.0). Anschließend werden die Cyberwar-Strategien der USA, Chinas, Russlands und weiterer führender Akteure besprochen. Weitere Kapitel befassen sich der Künstlichen Intelligenz, der Smart Industry, smarten Systemen und biologischen Anwendungen. Cyberwar – 27.09.2020 1 apl. Prof. Dr. Dr. K. Saalbach Inhalt 1.
