Phishing – Types And Precautions

Cyber Security

The criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication is known as Phishing.

Types of Phishing
Phishing is usually carried out by email or instant messaging and it often directs users to enter details at a fake website, which is similar to the legitimate one. Since the fake website is similar to the original one, it requires tremendous skill to determine whether a website is fake or not.

  1. Misspelled URLs: Phishers use some sort of deceptive techniques, which design a link in an e-mail (and the spoofed website it leads to) apparently belong to the spoofed organization by using misspelled URLs or of sub-domains. Sometimes the phishers make the anchor text for a link appear to be valid, whereas the link actually goes to the phishers site.
  2. Whaling: Phishing attacks directed specifically at senior executives and other high profile targets within businesses is known as Whaling.
  3. Image Phishing: Phishers have also used images instead of text to make it difficult for anti phishing filters.
  4. Cross site scripting: An attacker can even exploit flaws in the original website’s script against the victim making it even more difficult to detect since everything from the web address to the security certificates seem to be original. This technique is known as cross site scripting.
  5. Phone Phishing is the case where in a customer gets a call asking him to call back to discuss his problems while accessing his bank accounts. The person then is trapped into giving his sensitive information such as credit card information and the like.

Measures to counter phishing
People need to change their browsing habits when it comes to phishing. For example, when asked to reveal their sensitive information they should directly contact the company to make sure the mail is genuine and shouldn’t fall prey to mails that address them as “Dear Customer”. Paypal, for instance makes it a point to address the users by their usernames.

One of the major flaws of the user is the Click-through syndrome where he treats any pop-ups as a case of misconfiguration and proceeds with his work without heeding to the warning of the computer.
