What Is Phishing?

Phishing is a method employed by cybercriminals to access email accounts and systems using deception rather than defeating security protections. In basic phishing attacks, cybercriminals send an email that appears to be legal, tempting the victim to open an attachment or click on a link. This click could result in loading malware onto the victim’s computer or it could take the victim to a realistic-looking website. In several cases, the aim is to capture user credentials without the knowledge of the victim. Cybercriminals have discovered that it is usually easier to delude a victim into clicking a link instead of breaking through technology defenses.

Common Phishing Attacks

Email phishing
A phishing email is a fake email that appears to be like a crucial communication sent by a popular website or a bank. This email puts forth a tone of urgency and thus succeeds in tricking you into downloading an attachment or clicking on a link.

You will be taken to a fake website when you click on a link in a phishing email. This website could just drop a virus on your device or it could ask you to share classified information.

In many cases, downloading an attachment will infect your computer with a virus.

Phishing by SMS
This phishing attack that uses SMS is known as SmiShing. You will get an SMS, for instance, a WhatsApp message, informing you about an incredible offer. In this SMS you will be asked to redeem the offer by clicking on a link. After you click this link, you will be taken to a fake website that could infect your device with a virus or ask you to share confidential information.

Phishing by call
In a phishing call scam, you will get a phone call from a person acting like a bank manager, a software firm employee, or a known organization. This phishing call aims at tricking you into sharing private and vital details such as ATM PIN, expiry date, CVV, debit card number, and OTP.

Phishing techniques used by attackers:

  • Spoofing the sender address in an email to look like a reputable source and request sensitive information
  • Installing a Trojan through a malicious email attachment or advertisement allowing the intruder to exploit loopholes and then get all the required sensitive information
  • Attempting to gather company information using a phone by posing to be a known IT department or company vendor
  • Embedding a link in an email that redirects your employee to an unsafe website requesting sensitive information

How to prevent phishing scams

  • To prevent yourself from becoming a victim of a phishing scam, you will have to be extremely cautious with your personal information including your passwords and usernames.

  • Look out for emails that attempt to put forth a sense of urgency.
  • Directly get in touch with the company to inquire about such emails, when you suspect an email phishing activity, instead of using any link or other contact information provided in the email.
  • Always look out for emails that do not address you directly.
  • A few email phishing scams use your name in the email, whereas many are sent out as spam messages to thousands simultaneously.

  • Be extremely suspicious of any emails sent to you from trustworthy entities like your bank.
  • Avoid clicking on the link and instead type in the web address of the institution into the browser in order to access the website.
