Page 1 INFOSEC UPDATE 2006 -- June 19-20, 2006 01 Introduction Category 01 Introduction 2006-06-12 Introduction M. E. Kabay, PhD, CISSP WELCOME Welcome to the 2005 edition of the Information Security Year in Review (IYIR) project. In 1993 and 1994, I was an adjunct professor in the Institute for Government Informatics Professionals in Ottawa, Canada under the aegis of the University of Ottawa. I taught a one-semester course introducting information security to government personnel and enjoyed the experience immensely. Many of the chapters of my 1996 textbook, _The NCSA Guide to Enterprise Security_ published by McGraw-Hill were field-tested by my students. In 1995, I was asked if I could run a seminar for graduates of my courses to bring them up to date on developments across the entire field of information security. Our course had twenty students and I so enjoyed it that I continued to develop the material and teach the course with the NCSA (National Computer Security Association; later called ICSA and then eventually renamed TruSecure Corporation and finally CyberTrust, its current name) all over the United States, Canada, Europe, Asia and the Caribbean. After a few years of working on this project, it became obvious that saving abstracts in a WordPerfect file was not going to cut it as an orderly method for organizing the increasing mass of information that I was encountering in my research. -

The total value of fraudulent transactions conducted using cards issued within SEPA and acquired worldwide amounted to €1.8 billion in 2016 – a decrease of 0.4% compared with 2015. In relative terms, i.e. as a share of the total value of transactions, fraud dropped by 0.001 percentage point to 0.041% in 2016, down from 0.042% in 2015. Compared, again in relative terms, with the levels of fraud observed in 2012, fraud increased by 0.003 percentage points in 2016. Although there was an upward trend in card fraud between 2012 and 2015, it seems the trend is changing, given that fraud went down in 2016. With respect to the composition of card fraud in 2016, 73% of the value of card fraud resulted from card-not-present (CNP) payments, i.e. -
Phishing and Email Spoofing
NCUA LETTER TO CREDIT UNIONS NATIONAL CREDIT UNION ADMINISTRATION 1775 Duke Street, Alexandria, VA 22314 DATE: December 2005 LETTER NO.: 05-CU-20 TO: Federally Insured Credit Unions SUBJ: Phishing Guidance for Credit Unions And Their Members REF: Letter to Credit Unions #04-CU-12 Phishing Guidance for Credit Union Members DEAR BOARD OF DIRECTORS: In our Letter to Credit Unions #04-CU-12 Phishing Guidance for Credit Union Members, we highlighted the need to educate your membership about phishing activities. As the number and sophistication of phishing scams continues to increase, we would like to emphasize the importance of educating your employees and members on how to avoid phishing scams as well as action you and/or your members may take should they become a victim. Appendix A of this document contains information you may share with your members to help them from becoming a victim of phishing scams. Appendix B contains information you may share with your members who may have become a victim of phishing scams. Background Phishing is a form of social engineering, characterized by attempts to fraudulently acquire sensitive information, such as passwords, account, credit card details, etc. by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an e-mail or an instant message. Often the message includes a warning regarding a problem related to the recipient’s account and requests the recipient to respond by following a link to a fraudulent website and providing specific confidential information. The format of the e-mail typically includes proprietary logos and branding, such as a “From” line disguised to appear as if the message came from a legitimate sender, and a link to a website or a link to an e-mail address. -

Mr. McKelvey Turns Detective RELATED ARTICLE By KEVIN J. DELANEY • Internet Firms Face Legal Test on Staff Reporter of THE WALL STREET JOURNAL Advertising Fees3 April 6, 2005; Page A1 Nathan McKelvey began to worry about foul play when Yahoo Inc. refunded him $69.28 early last year. He grew more suspicious when a $16.91 refund arrived from Google Inc. The refunds were for "unusual clicks" and "invalid click activity" and they suggested someone was sabotaging Mr. McKelvey's advertising strategy. He pitches his charter-jet brokerage the way companies increasingly do: contracting with Yahoo and Google to serve up small text ads to anyone searching the Web using certain words, such as "private jet" or "air charter." He pays the search companies a fee every time someone clicks on his ads. But Yahoo and Google determined someone was clicking on CharterAuction.com Inc.'s ads with no intention of doing business, thus unfairly driving up the company's advertising costs. Mr. McKelvey, turning detective, combed through lists of "IP" addresses, the identifying codes supplied by computers when they access Web sites. -

Mastercard International Security and Risk Management: Credit Card Fraud
Cornish, Delpha, Erslon / MasterCard International Security and Risk Management MASTERCARD INTERNATIONAL SECURITY AND RISK MANAGEMENT: CREDIT CARD FRAUD Michael Cornish Kathleen Delpha Mary Erslon Executive Summary Credit card fraud is a growing concern of global proportions. Resourceful criminals are finding creative ways to capture private credit card holder account and identification information, and are using this information for fraudulent acquisitions of everything from personal care items to cars to home loans. Because of the universal reach of the Internet, criminals are easily able to perpetrate their crimes from anywhere in the world. The costs of credit card fraud reach nearly U.S. $2.5 billion annually. Internet fraud alone accounts for nearly 3% of Internet sales, or 30 times higher than credit card fraud rates in the “physical world.” While consumers are generally held harmless for credit card fraud, the payment industry and merchants absorb the losses from fraudulent purchases, and its participants continually search for ways to detect and prevent them. MasterCard International, the licensor and franchisor of the MasterCard branded family of payment products, is appropriately concerned about credit card fraud, since MasterCard research shows that the majority of their cardholders are alarmed about credit card fraud and the risk to their personal and financial information. MasterCard and other credit card systems are susceptible to two general categories of threats for fraudulent activities: Internal threats and external threats. Internal threats are those that evolve from collusion within the credit card system itself. However, internal threats are often mitigated by following good employment practices such as conducting employee background checks, and implementing strong controls that prevent unauthorized access to sensitive information and tracking authorized access. -

NATIONWIDE CREDIT CARD FRAUD PREVENTION Hendi Yogi Prabowo Recent Global Payment Fraud Statistics Indicate the Seriousness of Th
NATIONWIDE CREDIT CARD FRAUD PREVENTION Hendi Yogi Prabowo* Recent global payment fraud statistics indicate the seriousness of the credit card fraud problem. In the United Kingdom, in 2009 alone, losses from plastic (debit and credit) card fraud according to the report by the Financial Fraud Action UK (FFA) were $US696 million (Financial Fraud Action UK, 2010). In the same year, the Australian Payments Clearing Association (APCA) recorded losses of $US144 million from credit and charge card fraud perpetrated on Australian issued cards (Australian Payments Clearing Association, 2010). Both countries have been experiencing an upward trend in the losses from the offences over the past few years. Payment fraud statistics from the two countries suggest that card-not- present fraud (e.g. online credit card fraud) is the most common type of credit card fraud followed by skimming/counterfeit card fraud. This is different from a decade ago when skimming/counterfeit card fraud was statistically the most prevalent modus operandi. The emergence and growth of e-commerce has been a driving factor behind such a change. The implementation of the Chip and PIN technology in many countries, for example, has caused geographical displacement (e.g. from one country to another) and tactical displacement (e.g. from skimming/counterfeit card fraud to online credit card fraud) of credit card fraud. Many credit card fraud offenders are now better organized than before, resulting in higher losses from their offences. They even have their own supply and demand in the underground economy for stolen credit card information (Wilson, 2008, p. 5). Some of the proceeds from this economy are used to finance other crimes including terrorism1. -
