PHISING-THE NEW ONLINE CYBERCRIME

THE MEANING OF PHISING

In the cyber-world phising (also known as carding and spoofing) is a form of illegal act whereby fraudulently sensitive information is acquired, such as passwords and credit card details, by a person/entity masquerading as a trustworthy person or business in an apparently official electronic communication, such as an e-mail or instantaneous communication.

ORIGIN OF PHISING

Early attempts were made at phising in 1990s when offenders originally created on AOL accounts with fake, algorithmically generated credit card numbers – these accounts could last weeks or even months until new ones were required. AOL subsequently, brought in measures in late 1995 to prevent this, so early AOL crackers resorted to phising for legitimate AOL accounts.

Phising on AOL was closely linked with the warez community that exchanged pirated software. For instance, a cracker might pose as an AOL staff member and send an instant message to a potential victim, asking the victim to reveal his or her password. Later, AOL’s policy enforcement with respect to phising and warez became stringent and removed pirated software off AOL servers. AOL simultaneously developed a system to quickly deactivate any account involved in phising besides adopting other steps to combat this form of cyber fraud.

Of late, more recent phising attempts have been witnessed in relation to the customers of banks and online payment services. Such targeted versions of phising have been termed as spear phising.

STRONG INDICATORS OF PHISING ATTEMPTS

” If an e-mail addresses a user in a generic fashion (“Dear valued eBay member”) it is likely to be an attempt at phising.

“The appearance of links in the message- e.g. the link http://www.google.com@members.thinkbank.com/ may deceive a casual observer into believing that the link will open a page on www.google.com, whereas the link actually directs the browser to a page on members.thinkbank.com.

“Misspelled URLs or the use of subdomains are other common tricks used by phishers, e.g URL, and http://www.namebank.com.example.com

” Cross site scripting- In this attack method users may receive a message saying that they have to “verify” their account, by following a link to what appears to be an authentic website; in reality, the link is forged, although it is very difficult to spot that the link is manipulated to perpetrate this attack.

” Internationalised domain names in web browsers might allow visually identical web addresses to lead to different, possibly malicious, websites

ESTIMATE OF FINANCIAL LOSSES DUE TO PHISING

It is estimated that between May 2004 and May 2005, approximately 1.2 million computer users in the United States suffered losses caused by phising, totaling approximately $929 million USD. U.S. businesses lose an estimated $2 billion USD each year as their clients become victims to the phising activity.

The U.K also suffers from the drastic increase in phising activity. In March 2005, the amount of losses suffered by victim clients in the UK was approximately 504 million GBP.
