Q & A

What is phishing, and how does it work?

Phishing is a fraudulent attempt to obtain sensitive information by disguising as a trustworthy entity. It often occurs through emails or messages that appear to be from legitimate sources, tricking users into entering personal information like passwords or credit card details.

How can phishing emails be identified?

Phishing emails can be identified by checking the sender's email address, which may look suspicious. Also, emails asking for urgent action or containing unfamiliar links or attachments are often red flags. Checking for spelling and grammatical errors can also help spot phishing attempts.

What is smishing, and how does it differ from phishing?

Smishing is a type of phishing that occurs via SMS text messages. It is similar to phishing in that it attempts to trick individuals into clicking on fraudulent links or sharing personal information, but it specifically targets mobile phone users through text messages.

What should you do if you receive a suspicious email or SMS?

If you receive a suspicious email or SMS, do not click on any links or open attachments. Instead, verify the legitimacy of the message by contacting the company or institution directly using contact details from their official website. You can also report the suspicious message to your email provider or mobile carrier.

What are phishing websites, and how can they harm users?

Phishing websites are fake websites designed to look like legitimate ones. They trick users into entering personal information, such as login credentials or credit card numbers. Once entered, the information can be stolen or used maliciously. These sites may also install malware on the user's device.

What measures can be taken to protect yourself from phishing attacks?

To protect yourself from phishing attacks, verify URLs before clicking on links, avoid clicking on links in unsolicited emails or SMS, and ensure websites are secure by looking for 'https' in the URL. Additionally, enable multi-factor authentication (MFA) and use a password manager to avoid reusing passwords.

What is the importance of HTTPS when visiting websites?

HTTPS ensures that the data exchanged between your browser and the website is encrypted, making it more secure. Always check for 'https' in the URL and a padlock symbol to ensure you're on a legitimate and secure website before entering any sensitive information.

What is multi-factor authentication (MFA), and why is it important?

Multi-factor authentication (MFA) is a security measure that requires users to provide two or more verification factors to access an account. This adds an extra layer of security, making it harder for attackers to gain unauthorized access, even if they have your password.

What should you do if you receive an unexpected one-time password (OTP)?

If you receive an OTP without attempting to log in to an account, this could indicate that someone is trying to access your account. In this case, immediately change your password and report the suspicious activity to the service provider.

Why is it not safe to reuse passwords across multiple accounts?

Reusing passwords across multiple accounts increases the risk of a security breach. If one account is compromised, attackers can easily gain access to other accounts using the same password. It's important to use unique, strong passwords for each account to prevent this.
