Q & A

What is phishing and how does it work?

Phishing is a type of cyber attack where attackers send emails that appear to be from legitimate entities like internet service providers, banks, etc., to trick recipients into clicking on a link that leads to a fake website designed to gather personal information. The goal is to obtain sensitive data such as login credentials or financial information.

How can you identify a phishing email?

Phishing emails can often be identified by inconsistencies in the sender's address, poor grammar or spelling, and a sense of urgency to act. The email may also contain a link that leads to a website that looks similar to a legitimate one but has minor discrepancies, such as incorrect logos or misspelled URLs.

Why can't attackers make the address bar show the actual URL of the service provider in a phishing attempt?

Attackers cannot manipulate the address bar to show the actual URL of a service provider because it is a secure feature of web browsers designed to prevent URL spoofing. The address bar displays the true location of the website, which can help users identify phishing attempts.

What is the difference between phishing and pharming?

Phishing requires the user to click on a malicious link, whereas pharming involves the attacker taking control of a domain name system server or website to redirect all visitors to a fake site without the need for them to click on anything. Pharming is a more passive attack that affects all users who access the compromised server or site.

What is typosquatting and how is it used in phishing attacks?

Typosquatting is a type of URL hijacking where a domain name is registered with a slight misspelling of a popular or well-known domain, intending to trick users into typing the wrong address and landing on the attacker's site. This can be used in phishing to create a sense of legitimacy and gather personal information.

What is pretexting and how is it related to phishing?

Pretexting is a social engineering technique where attackers create a fabricated scenario to manipulate individuals into performing certain actions, such as clicking a link or providing personal information. It is related to phishing as it often provides the narrative or context that makes the phishing email seem believable.

How can vishing, smishing, and spear phishing be categorized under phishing attacks?

Vishing (voice phishing), smishing (SMS phishing), and spear phishing are all variations of phishing attacks that use different communication channels. Vishing uses phone calls, smishing uses text messages, and spear phishing targets specific individuals or groups with highly personalized emails to gather information or money.

What is whaling in the context of phishing attacks?

Whaling is a targeted phishing attack aimed at high-profile individuals, such as CEOs or CFOs, who have access to sensitive information or large sums of money. The goal is to deceive these individuals into performing actions that benefit the attacker, such as transferring funds.

How can attackers gather information about their targets before launching a phishing attack?

Attackers can gather information about their targets through open-source intelligence (OSINT) techniques, which involve searching for and analyzing publicly available data on the internet. This can include social media profiles, professional networking sites like LinkedIn, and other third-party websites that contain personal or professional information.

Why is it recommended not to click on links in emails and instead type the website address directly into the browser?

It is recommended to avoid clicking on links in emails to prevent falling for phishing attempts. Typing the website address directly into the browser allows users to verify the URL and ensure they are visiting the legitimate site, reducing the risk of landing on a phishing page.

How can users protect themselves against phishing attacks?

Users can protect themselves against phishing attacks by being vigilant, verifying the sender's email address, not clicking on suspicious links, using two-factor authentication, and keeping their software and security tools up to date. Additionally, they should be cautious about sharing personal information and use secure and private networks.
