Deep Thought: a Cybersecurity Story DEEP THOUGHT /////////// A cybersecurity story /////////// Alex Blau, Alexandra Alhadeff, Michael Stern, Scott Stinson, Josh Wright ideas42.org ⁄cyber // about ideas42 IDEAS42 USES INSIGHTS FROM BEHAVIORAL SCIENCE to help solve difficult social problems and make an impact at scale. We grew out of research programs in psychology and economics at top academic institutions and our work draws on decades of experimental scientific research in decision making, along with the most rigorous methods in program and policy evaluation. We work in a number of areas, including consumer finance, economic mobility and opportunity, health, education, energy efficiency, and international development. The conse- quences of the behavioral issues we tackle are often profound. A failure to adhere to medication can be life-threatening. Dropping out of school can prevent a person from achieving her potential. All too often, the reasons for these failures turn out to be small and remediable—but also usually overlooked or dismissed as unimport- ant. Our approach involves carefully diagnosing the behavioral issues that prevent otherwise well-designed programs and products from achieving their goals. We identify subtle but important contextual details that can influence behavior, and design innovative solutions that help to overcome or amplify their effects. Our work involves a lot of observation, plenty of patience, and a willingness to be surprised. Most of all, though, it involves asking the right questions. // acknowledgments THIS PROJECT WOULD NOT HAVE BEEN POSSIBLE without the sup- port of many individuals and institutions. ideas42 would like to thank the William and Flora Hewlett Foundation, whose generous support enabled us to examine crit- ical challenges in cybersecurity through the lens of behavioral science. We would like to give particular thanks to our Program Officer, Eli Sugarman, who lent us his sagely advice and guidance throughout the project and helped us get up to speed quickly on this incredibly diverse topic area by connecting us with the right people and content. Additionally, many thanks to the Hewlett Foundation President, Larry Kramer, for having the foresight to push forward cybersecurity as a major founda- tion initiative so that it gets the attention it deserves as a critical issue for our coun- try and humankind. We would also like to thank our colleagues at the New America Foundation including Ian Wallace, co-director of the cybersecurity program, and Robert Morgus, policy analyst, who provided us with their expertise throughout the project and connected us with many exceptional people. We would like to give special thanks to Ian in particular, who first suggested that we use the behavior- al perspective to take a look at cybersecurity challenges—without that nudge, we may not have endeavored down this path in the first place. Many thanks to those who supported our writing effort including the narrative wisdom of Peter Singer and Peter Kelly as well as Jason Hong, Nicole Becher, and Greg Michaelidis who provided feedback on our early draft. We are also indebted to the 60 experts from academia, government, policy, consulting, and industry who graciously contributed their time and invaluable insights to this project, and whose experiences informed the narrative we’ve crafted. There are many more people who helped to contribute to this work whom we may not have named here and we thank them as well for all their support. Finally, we’d like to acknowledge the coders, end users, IT adminis- trators, policy makers, and executives working at the forefront of cybersecurity who inspired this work.

Commuters, standing at the platform’s edge, began leaning out to glimpse the train’s light peeking out from around the bend. Others stood idly playing with their phones, reading books, or thumbing through papers in advance of the workday. But one woman, her face illuminated in cobalt, sat on a bench, hunched over her laptop screen. The train arrived on the platform like a riot. The doors opened, and a mass of bodies exchanged places. Those who got off clamored towards the stairs leading up to the street, while those onboard pressed themselves into some uninhabited nook of humanity and held on. The doors of the train closed following a loud “ding,” and the train lurched back into motion, continuing its journey beneath the city. However, the woman on the bench did not move. A dozen trains had come and gone while she sat there, but she paid as much attention to the bustle as a beach- goer would to the waves and rising tide. Instead, she continued to clack away on her keyboard, engrossed in her work, ignorant to the goings-on around her. As the train moved out of earshot, the woman stopped to scrutinize the con- tents of the screen in front of her. Two hundred and eighty-seven words, honed like a knife, filled the page of her word processor. She silently mouthed the words

  • A Comparative Analysis of Anti-Phishing Mechanisms: Email Phishing
    Volume 8, No. 3, March – April 2017 ISSN No. 0976-5697 International Journal of Advanced Research in Computer Science REVIEW ARTICLE Available Online at www.ijarcs.info A Comparative Analysis of Anti-Phishing Mechanisms: Email Phishing ShwetaSankhwar and Dhirendra Pandey BabasahebBhimraoAmbedkar University Lucknow, U. P., India Abstract: Phishing has created a serious threat towards internet security. Phish e-mails are used chiefly to deceive confidential information of individual and organizations. Phishing e-mails entice naïve users and organizations to reveal confidential information such as, personal details, passwords, account numbers, credit card pins, etc. Phisher spread spoofed e-mails as coming from legitimate sources, phishers gain access to such sensitive information that eventually results in identity and financial losses.In this research paper,aexhaustive study is done on anti-phishing mechanism from year 2002 to 2014. A comparative analysis report of anti-phishing detection, prevention and protection mechanisms from last decade is listed. This comparativeanalysis reports the anti-phishing mechanism run on server side or client side and which vulnerable area is coverd by it. The vulnerable area is divided into three categories on the basis of email structure. The number of vulnerabilties covered by existing anti-phishing mechanisms are listed to identify the focus or unfocused vulnerability. This research paper could be said as tutorial of a existing anti-phishing research work from decade. The current work examines the effectiveness of the tools and techniques against email phishing. It aims to determine pitfalls and vulnerability of anti-phishing tools and techniques against email phishing. This work could improve the understanding of the security loopholes, the current solution space, and increase the accuracy or performance to counterfeit the phishing attack.

For more information see the License page. Introduction Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your website's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. He would have access to your e-mail account, website, etc. Unimaginable. But who can remember all those passwords? Nobody, but KeePass can. KeePass is a free, open source, light-weight and easy-to-use password manager for Windows. The program stores your passwords in a highly encrypted database. This database consists of only one file, so it can be easily transferred from one computer to another. KeePass supports password groups, you can sort your passwords (for example into Windows, Internet, My Website, etc.). You can drag&drop passwords into other windows. The powerful auto-type feature will type user names and passwords for you into other windows. The program can export the database to various formats. It can also import data from various other formats (more than 20 different formats of other password managers, a generic CSV importer, ...). Of course, you can also print the password list or current view. Using the context menu of the password list you can quickly copy password or user name to the Windows clipboard.

    c 2016 Thasphon Chuenchujit A TAXONOMY OF PHISHING RESEARCH BY THASPHON CHUENCHUJIT THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2016 Urbana, Illinois Adviser: Associate Professor Michael Bailey ABSTRACT Phishing is a widespread threat that has attracted a lot of attention from the security community. A significant amount of research has focused on designing automated mitigation techniques. However, these techniques have largely only proven successful at catching previously witnessed phishing cam- paigns. Characteristics of phishing emails and web pages were thoroughly analyzed, but not enough emphasis was put on exploring alternate attack vectors. Novel education approaches were shown to be effective at teach- ing users to recognize phishing attacks and are adaptable to other kinds of threats. In this thesis, we explore a large amount of existing literature on phishing and present a comprehensive taxonomy of the current state of phish- ing research. With our extensive literature review, we will illuminate both areas of phishing research we believe will prove fruitful and areas that seem to be oversaturated. ii In memory of Nunta Hotrakitya. iii ACKNOWLEDGMENTS I would like to express my deepest gratitute to Professor Michael Bailey for guiding this work from start to finish. I also greatly appreciate the essential assistance given by Joshua Mason and Zane Ma.

    Technical Guides KeePass Password Manager Tutorial Wireguard Ubuntu Deployment SQM for 1 Gbps Lines With OpenWrt KeePass Password Manager Tutorial Introduction I don't trust online password managers because they are closed source and companies have been hacked in the past. If you look up "lastpass breached" in Google you can see my point. Keepass is open source and offline. Why put your trust in a company when you can create and access the database yourself? An honorable mention is bitwarden. They are also open-source and you have the option of hosting your own bitwarden server at home as an option. If you want to pay and are willing to trust a company and have your passwords encrypted on their cloud they would be your best bet.

  • The Usable Security of Passwords Based on Digital Objects: from Design and Analysis to User Study∗
    The Usable Security of Passwords based on Digital Objects: From Design and Analysis to User Study∗ Mohammad Mannan Tara Whalen, Robert Biddle Electrical and Computer Engineering Dept. P.C. van Oorschot University of Toronto School of Computer Science Toronto, Canada Carleton University [email protected] Ottawa, Canada Abstract Despite all efforts, password schemes intended to deploy or encourage the use of strong passwords have largely failed. As an interesting alternative to enable users to create, maintain and use high quality passwords willingly, we propose Object-based Password (ObPwd), leveragingthe universe of personal or personally meaningful digital content that many users now own or have access to. ObPwd converts user- selected digital objects to high-entropy text passwords. Memorization of exact passwords is replaced by remembering password objects. We present the design details, variants, and usability and security analysis of ObPwd; briefly discuss (publicly available) prototype implementations in various forms on several platforms; and as a major focus, report on the results of a hybrid in-lab/at-home user study on 32 participants. The results suggest the scheme has good usability, with excellent memorability, acceptable login times, and very positive user perception, achieved while providing strong security for the threat context explored. While we anticipate further experience with ObPwd will lead to improved security and usability, and best practice guidelines, we believe this work lays the foundations for a promising password selection paradigm. 1 Introduction and Motivation Text passwords remain ubiquitous, despite endless criticism. Independent studies conducted decades apart reveal that people consistently choose ‘weak’ passwords [19, 6] for many reasons, including users trying to manage on average 25 password-protected accounts [7].

  • Revisiting Security Vulnerabilities in Commercial Password Managers?
    Revisiting Security Vulnerabilities in Commercial Password Managers? Michael Carr1 and Siamak F. Shahandashti2 1 Piksel, York Science Park, YO10 5ZD, UK [email protected] 2 Dept. of Computer Science, University of York, YO10 5GH, UK [email protected] Abstract. In this work we analyse five popular commercial password managers for security vulnerabilities. Our analysis is twofold. First, we compile a list of previously disclosed vulnerabilities through a compre- hensive review of the academic and non-academic sources and test each password manager against all the previously disclosed vulnerabilities. We find a mixed picture of fixed and persisting vulnerabilities. Then we carry out systematic functionality tests on the considered password managers and find four new vulnerabilities. Notably, one of the new vulnerabilities we identified allows a malicious app to impersonate a legitimate app to two out of five widely-used password managers we tested and as a result steal the user's password for the targeted service. We implement a proof- of-concept attack to show the feasibility of this vulnerability in a real-life scenario. Finally, we report and reflect on our experience of responsible disclosure of the newly discovered vulnerabilities to the corresponding password manager vendors. Keywords: Vulnerability Testing · Password Managers · Password Man- ager Security · Authentication. 1 Introduction Passwords remain the dominant authentication mechanism in the digital realm despite their shortcomings. Furthermore, they are expected to persist as a pri- mary authentication mechanism for the some time [6]. Among the tools that can greatly reduce the cognitive burden of remembering multiple passwords for arXiv:2003.01985v2 [cs.CR] 17 Mar 2020 multiple services are password managers.
