INTRODUCTION
 Phishing is the most powerful and popular attack for
hacking into emails and web accounts.
 Cyber criminals use this attack to hack into bank
accounts, Facebook accounts and email account of
innocent people.
 Every year, most of the biggest cyber crime case
involve this attack.
 So we must know what is Phishing and how to
protect your accounts from phishing attack.

WHAT IS PHISHING?
 Phishing is the act of fooling a computer user into
submitting personal information by creating a
counterfeit it website that looks like a real (and
trusted)site.
 It is a hacker technique of "fishing" for passwords
and other secret financial info.

THE DIFFERENT FLAVOR OF PHISHING ATTACK

TYPES OF PHISHING:
1) Deceptive phishing
2) Spear phishing
3) Whaling
4) Pharming

TYPES OF PHISHING
1. Deceptive phishing:
 Sending a deceptive email, in bulk, with a “call to action” that
demands the recipient click on a link.
 In this case, an attacker attempts to obtain confidential
information from the victims.
 Attackers use the information to steal money or to launch
other attacks.
 E.g A fake email from a bank asking you to click a link and
verify your account details.

TYPES OF PHISHING
2. Spear phishing:
 Spear phishing targets specific individuals instead of a wide
group of people.
 Attackers often research their victims on social media and
other sites.
 That way, they can customize their communications and
appear more authentic.
 Spear phishing is often the first step used to penetrate a
company’s defenses and carry out a targeted attack.

TYPES OF PHISHING
3.Whaling:
 When attackers go after a “big fish” like a CEO,
it’s called whaling.
 These attackers often spend considerable time
profiling the target to find the opportune moment
and means of stealing login credentials.
 Whaling is of particular concern because high-
level executives are able to access a great deal
of company information.

TYPES OF PHISHING
4.Pharming
 Similar to phishing, pharming sends users to a
fraudulent website that appears to be legitimate.
 However, in this case, victims do not even have
to click a malicious link to be taken to the bogus
site.
 Attackers can infect either the user’s computer
or the website’s DNS server and redirect the
user to a fake site even if the correct URL is
typed in.

WHAT THE ARE DANGERS OF PHISHING
ATTACKS?
 Sometimes attackers are satisfied with getting a
victim’s credit card information or other personal
data for financial gain.
 Other times, phishing emails are sent to obtain
employee login information or other details for
use in an advanced attack against a specific
company.

HOW DO I PROTECT AGAINST PHISHING
ATTACKS?
1.User education
 One way to protect your organization from
phishing is user education.
 Education should involve all employees.
 High-level executives are often a target Teach
them how to recognize a phishing email and
what to do when they receive one.
 Simulation exercises are also key for assessing
how your employees react to a staged phishing
attack.

2.Security technology
 No single cyber security technology can
prevent phishing attacks.
 Instead, organizations must take a layered
approach to reduce the number of attacks
and lessen their impact when they do occur.
 Network security technologies that should be
implemented include email and web security,
malware protection, user behavior
monitoring, and access control.

CAUSES OF PHISHING
 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

EFFECTS OF PHISHING
 Internet fraud
 Identity theft
 Financial loss to the original institutions
 Difficulties in Law Enforcement Investigations
 Erosion of Public Trust in the Internet.

CONCLUSION
 No single technology will completely stop phishing.
 However, a combination of good organization and
practice, proper application of current technologies, and
improvements in security technology has the potential to
drastically reduce the prevalence of phishing and the
losses suffered from it.
