Phishing, Fraudulent, and Malicious Websites

2008-06-25来源:

Whether we like it or not, we are all living in the Information Age. We have nothing left but adapt to rapidly developing information technology, no matter who we are and what we do for living.

The Internet, in particular, means for us boundless opportunities in life and Business - but also lots of dangers unheard of just a decade ago. We should be aware of these dangers if we want to use the huge potential of the Internet and to avoid the hazards it brings us.

Warning: There are websites You'd Better Not Visit

Phishing websites

Thanks to authors of numerous articles on this topic, "classic" phishing technique is relatively well known. This scam involves setting bogus websites and luring people to visit them, as a rule, by links in emails. Phishing website is disguised to look like a legitimate one -- of a bank or a credit card company, and users are invited to provide their identifying information. Sites of this kind are used solely to steal users' passwords, PIN numbers, SSNs and other confidential information.

At first phishing consisted only of a social engineering scam in which phishers spammed consumer e-mail accounts with letters ostensibly from banks. The more people got aware of the scam, the less spelling mistakes these messages contained, and the more these fraudulent websites resembled legitimate ones. Phishers are getting smarter.

The problem is that this Trojan contains a keylogger which lurks at the background until the user of the infected PC visits one of the specified websites. Then the keylogger comes to life to do what it was created for -- to steal information.

It seems that this technique is actually a separate scam aimed at stealing personal information and such attacks are on the rise. Security vendor Symantec warns about commercialisation of malware -- cybercriminals prefer cash to fun, so various kinds of information-stealing software are used more actively.

Fraudulent websites are on the rise

Websense Security Labs -- a well-known authority in information security -- noticed a dramatic rise in the number of fraudulent websites as far back as in the second half of 2004. These sites pose as ones for e-commerce; they encourage users to apply for a reward or purchase something, of course never delivering the product or paying money. The most popular areas for such fraud are online pharmacies, lottery scams, and loan / mortgage sites. Experts predict there will be more fake merchants in future and their scams will become more sophisticated.

A Hybrid Scam

In April Panda software warned Internet users of a new particularly brazen scam aimed at stealing confidential information. The technique used here looks like a hybrid between phishing and a fraudulent website.

Panda software identified several websites offering cheap airline tickets which in fact weren't selling anything; the aim was to cheat users out of credit card details.

This scam is very simple; the thieves simply wait until some unsuspecting user who is searching for,
