    • 13. • Led by two brothers – Guy Levi,22, and the ringleader, DavidLevi, 28• Complaints were received fromeBay users who had paid forlaptops and Rolex watches thatnever arrived• Lett, the computer expert in thegang used a software tool ofthe spam trade called AtomicHarvester to sweep theinternet, gathering around6,000 email addresses. Hewrote to more than 2,000 ofthese addresses, purporting tobe eBay.The David Levi eBay Phishing Scam (2005)
    • 14. The Levis and Lett wanted the usernames and passwords ofhighly-rated eBay sellers. Anyone trading on eBay has a feedbackscore and a percentage feedback rating. If a seller has positivefeedback rated at, say, 98%, a bidder will trust the seller todeliver. So Lett hijacked such accounts. First he changed thepasswords, to lock out the real account holders; then he and theLevis started selling.Those who fell for their ads for high-value items like Sony Vaiolaptops and Rolex Daytona watches – using text and images liftedfrom legitimate ads – would be contacted by email andpersuadedto pay off-line.Police located 160 people who paid money to David Levi’s gang;there may have been others. The police had evidence of almost£200,000 in criminal gains but they suspect that the total figurewas more than twice as much.Source: Out-Law Magazine Winter 2005 Issue 13

    • 30. A good phish targets weaknesses and lapses in human nature. For example,we often click “OK” without reading a warning.A phish needs YOUR HELP in order to succeed.Phishing is often conducted by organized crime.Phishing groups are dynamic and can be in any country. They often usepeople in multiple countries simultaneously.Credit and debit card users are the primary targets of phishers right now(going for fast cash).Phishing can come in more than one form: email, instant messages, pop-up,online postings, and telephone.Phishing Quick Factshttps://www.hvfcu.org/eservices/safe-computing/phishing/phishing-quick-facts
    • 31. A phish NEVER includes a real email address for the phisher, so itis pointless to reply to one.A phish has a hook (Trust us. Here’s why.), a required action(Here’s what we want you to do.), and a push (Hurry, act now!).Most servers that host phish sites are legitimate servers thathave been compromised. Phishers must use the site’s URL or IPaddress in the phish. Some servers that host phish sites arefraudulently registered. Phishers can use any URL and try tomake it similar to the victim site.https://www.hvfcu.org/eservices/safe-computing/phishing/phishing-quick-factsPhishing Quick Facts

Phishing e-mail mighteven claim that your response is required because your accountmight have been compromised.How to tell if an e-mail message is fraudulent
    • 41. "Dear Valued Customer."Phishing e-mail messages are usuallysent out in bulk and often do not contain your first or last name."Click the link below to gain access to your account."HTML-formatted messages can contain links or forms that you can fillout just as youd fill out a form on a Web site. The links that youare urged to click may contain all or part of a real companysname and are usually “masked”, meaning that the link you seedoes not take you to that address but somewhere different,usually a phony Web site.
    • 42. Con artists also use Uniform Resource Locators (URLs)that resemble the name of a well-known companybut are slightly altered by adding, omitting, ortransposing letters.For example, the URL "www.microsoft.com" couldappear instead as:•www.micosoft.com•www.mircosoft.com•www.verify-microsoft.com
