phishing techniques
Phishing techniques:

Email techniques :-

  • Attachments to e-mails –
  • Use of font differences –
  • Hyperlinks to similar domain names-
  • Filling forms .

Web –based techniques:-

  • Fake banner advertising.
  • IM .
  • Fake websites(having similar domain names).
  • Browser vulnerabilities,Spyware,malware.
phishing techniques1
Phishing techniques:

Spoofed mails:

  • A formal email request is sent to the user to send back sensitive information.
  • Some scams are like winning notifications which ask for credit card number and other information.

Spoofed websites:

  • Here fake websites of financial organisation etc are crafted by attackers similar to the legitimate site.
  • Mostly these websites are http enabled not https .
some tricks
Some tricks:

To reduce suspicion and increase authenticity:-

  • The URLs might be obfuscated to look like the legitimate site.

Example :http://privatebanking.mybank.com as

http://privatebanking.mybank.com.ch

http://mybank.privatebanking.com

http://privatebanking.mybonk.com

  • It uses real logos and corporate identity elements in the spoofed website.
typical attack
Typical attack:
  • Attacker sends a large number of people of spoofed emails(that act like to be coming from a legitimate organisation) to users.
  • The emails have hyperlink to spoofed websites wherein the users are directed to.
  • The victims are then asked to enter their sensitive information.
phishing techniques2
Phishing techniques:

Instant messenger:

  • As IM clients allow for embedded dynamic content (such as graphics, URLs, multimedia includes, etc.) to be sent by channel participants.
  • Usage of bots (automated programs that listen and participate in group discussions) in many of the popular channels, means that it is very easy for a phisher to anonymously send semi-relevant links and fake information to would-be victims.
phishing techniques3
Phishing techniques

Web based- Phishing attacks :

  • The purpose of key loggers is to observe and record all key presses by the customers.
  • Some sophisticated phishing attacks make use of code designed to take a screen shot of data that has been entered into a web-based application
countermeasure against phishing
Countermeasure against phishing

The defensive mechanisms to counter the phishing technique threats.

  • The Client-side – this includes the user’s PC and desktop.
  • The Server-side – this includes the business’ Internet visible systems and custom applications.
  • Enterprise Level – distributed technologies and third-party management services.

At the client-side, protection against phishing can be afforded by:

  • Locking-down browser capabilities
  • Digital signing and validation of email
  • General security awareness
server side
Server side:
  • Improving customer awareness
  • Providing validation information for official communications
  • Ensuring that the Internet web application is securely developed and doesn’t include easily exploitable attack vectors.
  • Using strong token-based authentication systems
  • Keeping naming(domain name) systems simple and understandable
enterprise level
Enterprise level:
  • Automatic validation of sending e-mail server addresses
  • Digital signing of e-mail services
  • Monitoring of corporate domains and notification of “similar” registrations
  • Perimeter or gateway protection agents
  • Third-party managed services
future scope of phishing
Future scope of phishing:
  • We expect that the future of scope of phishing is expected to rise especially in the mobile environment.
  • The mobile operating systems and browsers lack the security indicators,as a result the users cannot always check if they are in the correct site .
  • Android phones could be more vulnerable to phishing .
