• 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)
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

What Does a Phishing Scam Look Like?As scam artists become more sophisticated, so dotheir phishing e-mail messages and pop-upwindowsThey often include official-looking logos fromreal organizations and other identifying informationtaken directly from legitimate Web sites
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
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

Here are a few phrases to look for"Verify your account."Businesses should not ask you to sendpasswords, login names, Social Security numbers, or otherpersonal information through e-mail. If you receive an e-mailfrom anyone asking you to update your credit card information,do not respond: this is a phishing scam."If you dont respond within 48 hours, your account will beclosed."These messages convey a sense of urgency so that youllrespond immediately without thinking. 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
"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.
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
Never respond to an email asking for personal informationAlways check the site to see if it is secure. Call the phone number if necessaryNever click on the link on the email.

Since legitimate sites can be hacked and modifiedto contain malware, don’t visit a website if a browser warning is shown, nomatter how well-known the website is to you.P.S: Always shred your documents before discarding them.How do I avoid from becoming a victim …
“It’s hard for criminals to duplicate my institution’s website,so if it looks good, it must be the real site.”The Truth: Many fake sites look identical to the originalsite.“If I see a lock anywhere on the page, I know it is a securewebsite.”The Truth: The lock or key that signifies a secure site mustappear on the body or chrome of the browser, not as apicture on a webpage.“I can tell by the poor grammar if it is a phish."The Truth: Fake sites often have perfect grammar andspelling.Don’t fall for the Myths …https://www.hvfcu.org/eservices/safe-computing/phishing/phishing-quick-facts
