Phishing “ In computing, phishing (also known as carding and spoofing) is a form of social engineering, characterized by attempts to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to "fish" for users' financial information and passwords. “ http://en.wikipedia.org/wiki/Phishing Copyright © 2008 by Helene G. Kershner
Phishing – In the Beginning In the 1990s unethical AOL users created false accounts with “algorithmically generated credit card numbers — these accounts could last weeks or even months until new ones were required. AOL eventually brought in measures in late 1995 to prevent this, so early AOL crackers resorted to phishing for legitimate AOL accounts.” Individuals involved in such measures were often those involved in illegal sale and distribution of boot leg software. http://en.wikipedia.org/wiki/Phishing Copyright © 2008 by Helene G. Kershner
Phishing – In the Beginning The phisher or cracker would “pose as an AOL staff member and send an instant message to a potential victim, asking the victim to reveal his or her password.” http://en.wikipedia.org/wiki/Phishing#Early_phishing_on_AOL Stutz, Michael: “AOL: A Cracker's Paradise?”, Wired News, January 29, 1998.Stutz, MichaelAOL: A Cracker's Paradise?Wired News The phisher would use the now all to common technique of sending some kind of message to the unsuspecting AOL user asking to give “up sensitive information … include text such as "verify your account" or "confirm billing information". Once the victim had submitted his or her password, the attacker could then access the victim's account and use it for various criminal purposes, such as spamming.” Copyright © 2008 by Helene G. Kershner
Phishing – Moving on from AOL In 1977 AOL adjusted its security policies making it very difficult for such illegal activities to occur. As a result these activities migrated elsewhere on the Internet. Phishing is now unfortunately Everywhere! Estimated losses from phishing from May 2004-May 2005 exceed three billion dollars to individuals and businesses in the US alone. More than 1.2 million US citizens were effected. –http://en.wikipedia.org/wiki/Phishing#Early_phishing_on_AOLhttp://en.wikipedia.org/wiki/Phishing#Early_phishing_on_AOL Copyright © 2008 by Helene G.

All, Some CSE faculty and staff are wondering if this message is legitimate. In fact, it is spam designed to harvest and exploit your personal information. As a general rule, if you ever receive email that asks for your password, it's malicious spam and you should ignore it. UBIT (and your bank, credit card company, mortgage holder, etc.) will never ask you for your password via email. Other red flags in this message include: 1. The message purports to be from a UB database administrator, but it originates from an email address outside the buffalo.edu domain. UBIT policy dictates that official correspondence must originate from UBITName@buffalo.edu addresses. 2. The message is poorly written and ungrammatical. UBIT personnel are usually pretty good about proofreading. 3. The message's content attempts to sound official and jargon-y but is ultimately without meaning or substance. Yours in healthy skepticism, UBITName@buffalo.edu Copyright © 2008 by Helene G. Kershner

Behind the Machine: Phishing The FTC suggests If you get an email or pop-up message that asks for personal or financial information, do not reply. And don’t click on the link in the message, either. Area codes can mislead. Some scammers send an email that appears to be from a legitimate business and ask you to call a phone number to update your account or access a “refund.” Because they use Voice Over Internet Protocol technology, the area code you call does not reflect where the scammers really are. Copyright © 2008 by Helene G. Kershner
Behind the Machine: Phishing Don’t email personal or financial information if requested by a message to you! Look for indicators that the site is secure, like a lock icon on the browser’s status bar or a URL for a website that begins “https:” (the “s” stands for “secure”). Unfortunately, no indicator is foolproof; some phishers have forged security icons Review credit card and bank account statements as soon as you receive them to check for unauthorized charges. http://www.ftc.gov/bcp/edu/pubs/consumer/alerts/alt127.shtm Copyright © 2008 by Helene G.
