Nowadays, with the advancement of technology, financial transactions have become very simple, and it is enough to enter your credit card after entering the database portal.
For example, if an organization intends to launch an advertising campaign, there is no need to inform and talk to each employee, and this is done by sending a group email to employees. Phishing is one of the most common types of crimes and attacks. This article will explain what phishing is and what we should do to avoid falling into its trap.
What is phishing, and how is it done?
Phishing is a cyber-attack or, more precisely, social engineering attack. This type of cyber attack is performed for two purposes:
Theft of confidential personal information such as passwords, emails and passwords and confidential information of bank credit cards;
Theft of confidential information of private and governmental organizations and organs.
For example, we assume that you are directed to the bank portal where you intend to pay in the first case. If the person planning these cyber attacks targets you, you will enter a fake exit precisely like the leading portal. If you enter your bank card information on this page and the phony portal, all this information will be kept confidential. Fisher will be in charge.
In the latter case, an email is sent to all employees of a private or public organization that contains a malicious link or malware. Anyone who falls victim to these attacks and clicks on the link will be redirected to a page where the organization’s confidential information is provided to the attacker. It can then install malware on employees ‘(or even employers’) operating systems and steal organ money or intellectual property.
Types of phishing attacks
There are several types of phishing, the most common of which are sending emails containing malicious links and malware. Of course, there are other types that we will provide information about each in the following.
- In this type of attack, a hacker thoroughly examines all the personal information of one or more collection employees, including his name, place of work, job title, email address, and trusted individuals. He then tries to force the victim to transfer money or do other things by sending persuasive messages.
- The main target in this type of phishing attack is employers and high-ranking officials. There is usually a lot of personal information about these people on social media and cyberspace. A fisherman uses this information to send personalized messages and tricks the victim into achieving his goals.
- In these two phishing attacks, smartphones are used instead of sending emails and similar solutions. The hacker acts by sending a text message to the mobile phone or making a phone call. In most cases, after making a phone call, the victim is told that their bank account is vulnerable to fraud and that they must provide complete information about their credit card and bank account to the person who called them as soon as possible.
- In this type of cyber attack, a hacker in one of the social networks (Instagram, Twitter, etc.) creates an account that counts profile pictures, number of followers, descriptions, and other things exactly like a brand or a company. It has a good platform. It then communicates with the company in various ways, targeting it and abusing them in multiple ways.
How do we not fall into the trap of phishing?
As mentioned, cybercriminals use a variety of tactics, including email, text messaging, social media messaging, and phone calls, to gain access to personal information and confidential information. But there are signs that you can pay attention to these attacks and not fall into the trap of phishing. In this section, we will introduce some of the most important ones.
Request immediate action
Suppose you receive an email or message explaining that to gain a particular benefit or reward or to avoid losses, you should immediately click on the link provided to you. In that case, it is better to wait a while and send the message carefully And check the link.
Creating a sense of urgency is one of the main ways to use phishing to deceive the victims of this cyber attack.
Receive the first message or email from anonymous senders
Receiving a message or email for the first time from a sender you do not know is not uncommon, especially if the sender is outside the collection in which you work. It is better to scrutinize the message and its attachment in such cases.
Spelling or grammatical errors in text and message links
Reputable public and private entities usually have an editorial team that examines the text of messages to find spelling or grammatical mistakes before sending messages to customers and the target market. If you receive a message that contains spelling or grammatical errors, you should be skeptical.
Minor and subtle changes in the URL bar links of reputable websites
When you receive a message designed and written for a phishing attack, clicking on the link attached to the notice will take you to a website that looks exactly like the website you are looking for but is fake.
If you enter your account information on a fake website, it will be given to the hacker, and he can use it for his purposes.
How to prevent phishing attacks?
First of all, you need to know enough about phishing attacks and their types and when to doubt the accuracy of the message sent to you or the contact made with you. For example, if someone calls you and asks for your bank account information, you should not give them this confidential information until you are sure it is correct.
Another thing to keep in mind is constantly updating the operating system, antivirus software, and security patches (firewall, etc.) to the system you are using. In this case, it would be much more difficult if Fisher wanted to transfer the malware to your system. Most popular browsers such as Google Chrome and Firefox also have anti-phishing plugins to prevent such attacks effectively.
