what is phishing in cyber security

Phishing is a pervasive threat in the realm of cybersecurity. It is a technique employed by cybercriminals to deceive individuals into revealing sensitive information or performing actions that could compromise their security. In this article, we’ll delve into the world of phishing, exploring its types, how it operates, the consequences, and, most importantly, how to defend against it.

What is phishing ?

Phishing is a malicious practice where cyber attackers impersonate trusted entities to trick individuals into revealing personal information such as usernames, passwords, credit card details, and more. This deceit is often carried out through various means, including emails, websites, or phone calls. It preys on the vulnerability of human trust.

What is phishing, and what is its purpose ?

Phishing is a type of social engineering assault in which a perpetrator pretends to be a reliable organization (such a bank, credit card company, or government agency) in an effort to dupe victims into disclosing sensitive data, like login credentials, credit card details, or Social Security numbers. Phishing assaults can be launched by email, texts, calls, social media, or even in person.

A phishing attack’s goal is to obtain personal data the perpetrator can use for fraud or identity theft. For instance, an attacker can access a victim’s bank account using stolen login information and move money out of it, or they might start new credit accounts in the victim’s name using stolen Social Security numbers.

Phishing attacks are one of the most common types of cybercrime, and they can be very effective. Attackers are constantly developing new techniques to make their phishing emails and websites more convincing, and they often target specific groups of people, such as employees of large companies or students.

Types of Phishing Attacks

Phishing attacks can take many different forms, however some of the more popular ones are as follows:

• Email phishing: This is the most common type of phishing attack, and it involves sending fraudulent emails to victims. The emails may appear to be from a legitimate organization, such as a bank, credit card company, or government agency. The emails may contain links to fake websites or ask the victim to enter their personal information directly into the email.
• Spear phishing: Spear phishing is a more targeted type of phishing attack that is directed at specific individuals or groups of people. Attackers may gather information about their victims from social media or other online sources. The emails used in spear phishing attacks are often more convincing than traditional phishing emails, as they are tailored to the victim’s specific interests or needs.
• Whaling: Whaling is a type of spear phishing attack that is specifically targeted at high-profile individuals, such as CEOs and other executives. Whaling attacks can be very successful, as the victims are often more likely to trust the emails and to have access to sensitive information.
• Smishing: Smishing is a type of phishing attack that is carried out via text message. Smishing messages are often similar to email phishing messages, but they may also contain links to malicious apps or websites.
• Vishing: Vishing is a type of phishing attack that is carried out via phone call. Vishing scammers may impersonate representatives from a legitimate organization and ask the victim to provide personal information or to download malware.

In addition to these common types of phishing attacks, there are many other variations, such as:

• Angler phishing: Angler phishing attacks are carried out via social media. Attackers may create fake social media profiles or post links to malicious content in social media groups.
• Pharming: Pharming attacks involve redirecting users to fake websites without their knowledge. This can be done by poisoning the DNS cache or by exploiting vulnerabilities in web browsers.
• Man-in-the-middle attacks: Man-in-the-middle attacks entail listening in on conversations between two people while posing as one of them. Users may be sent to fraudulent websites or have their personal information stolen using this.

How Phishing Works

Phishing works by exploiting human psychology. Attackers create emails or other communications that are designed to look like they are from a trusted source, such as a bank, credit card company, or government agency. The emails may contain links to fake websites that look like the real websites of these organizations.

If a victim clicks on a link in a phishing email and enters their personal information on the fake website, the attacker can steal that information. Attackers can then use the stolen information to commit fraud or identity theft.

Here is a typical example of a phishing attack:

1. The attacker sends the victim a phishing email. The email may appear to be coming from a reputable company, like a bank.
2. The email may contain a link to a fake website that looks like the real website of the bank.
3. The email may ask the victim to enter their personal information on the fake website, such as their login credentials or credit card number.
4. If the victim clicks on the link and enters their information on the fake website, the attacker can steal that information.

Attackers can use the stolen information to commit fraud or identity theft. For example, they may use the stolen login credentials to access the victim’s bank account and transfer money out of it, or they may use the stolen credit card number to make fraudulent purchases.

Phishing attacks can be very effective because they are designed to exploit human psychology. People are more likely to click on links and enter their personal information if they think they are communicating with a trusted source.

How To Prevent Phishing Attacks?

You can take the following actions to avoid phishing scams:

1. Study the characteristics of phishing attacks.

Attackers can carry out a phishing attack in a variety of methods. Being aware of different attack types and what they could resemble will help to lessen the likelihood of becoming a victim. You can also read about these assaults’ more recent methods to stay informed. This can assist you in avoiding any potential danger or assault.

2. Avoid clicking on links in emails

Avoid clicking on any strange links in emails that you receive. Check the email for problems by reading it from beginning to end. Multiple grammatical or typographical problems are frequently seen in phishing emails. Errors could also be present in the email’s subject line or email address. If the email appears suspicious, even if you do not uncover any mistakes, you might choose to report it. Consider personally contacting the sender to confirm that they actually sent the email if you know them.

3. Install anti-phishing plugins

Increasing cyber security is a good method to fend off future threats. Installing anti-phishing browser plugins will help you achieve this. Through prompts, these plugins can assist you in spotting possible phishing attempts. Plugins may come pre-installed on some browsers. Additionally, you can add reliable plugins to your browser by downloading them from the internet.

Numerous websites may provide user information to third parties for marketing purposes, but doing so could make your information vulnerable to hackers. Regularly changing your passwords can stop criminals from accessing your accounts using outdated information.
