 Phishing is the act of attempting to acquire
information such as username, password and
credit card details as a trustworthy entity in an
electronic communication.
 Communications purporting to be from
popular social web sites ,auction sites, online
payment process or IT administrators are
commonly used to lure the unsuspecting
public .Phishing emails may contain links to
websites that are infected with malware.

 LINK MANIPULATION
 FILTER EVASION
 WEBSITE FORGERY
 PHONE PHISHING

 In this example, targeted at South Trust Bank users, the
phisher has used an image to make it harder for anti-phishing
filters to detect by scanning for text commonly used in
phishing emails.

 Deceptive - Sending a deceptive email, in bulk, with a “call
to action” that demands the recipient click on a link.
 Malware-Based - Running malicious software on the
user’s machine. Various forms of malware-based phishing are:
 Key Loggers & Screen Loggers
 Session Hijackers
 Web Trojans
 Data Theft

 DNS-Based - Phishing that interferes with the integrity of
the lookup process for a domain name. Forms of DNS-based
phishing are:
 Hosts file poisoning

 Man-in-the-Middle Phishing - Phisher positions himself
between the user and the legitimate site.

 Content-Injection – Inserting malicious content into legitimate site.
Three primary types of content-injection phishing:
 Hackers can compromise a server through a security
vulnerability and replace or augment the legitimate content with
malicious content.
 Malicious content can be inserted into a site through a cross-site
scripting vulnerability.
Malicious actions can be performed on a site through a SQL
injection vulnerability.

 Misleading e-mails
 No check of source address
 Vulnerability in browsers
 No strong authentication at websites of banks and
financial institutions
 Limited use of digital signatures
 Non-availability of secure desktop tools
 Lack of user awareness
 Vulnerability in applications

and improvements in security technology has the
potential to drastically reduce the prevalence of
phishing and the losses suffered from it.
