How to protect yourself against cybercrime

As cybercrime is growing and evolving every day, it is becoming increasingly difficult for people to identify and protect themselves against online fraud. It is vital that you know what cybercrime is and how you can protect yourself against it. Here are some tips to help you protect yourself:

Understand how hackers identify you

Identification is the first step in online fraud. It involves identifying your computer and all other electronic devices you use to access the internet. It may involve the identification of a credit card, a debit card, or a password.

One of the most common ways of identifying people and their computers and devices is through cookies. Cybercriminals place cookies in your browser and use them to identify you and your computer. Cookies are small pieces of information that are stored on your device and sent back to the computer hosting them whenever you visit a website.

Never reuse passwords for any account. Use a password manager such as 1Password, LastPass, or 1Password, and you can make sure that your different accounts have unique passwords, so if one account is hacked, your others are not at risk. Never access any of your accounts on public computers. If you must do this, only access them while at your own home or office. You may also use a virtual private network, or VPN to access them.

Understand phishing emails and what they can do

You will often receive emails and phone calls from scammers. These emails and phone calls are designed to mislead you and trick you into giving them your private information. Scammers pretend to be from companies you trust. Cybercriminals may also impersonate other individuals or companies, such as doctors, banks, bank employees, or government agencies. They may send you a copy of actual payment or bank document, asking you to change your information, or they may just ask you to enter your details or give you your password.

Cybercriminals will often use your personal information to get your money. For example, cybercriminals will ask for your account number or your bank details. When you provide your bank details, cybercriminals can move your money from your account to their own without your knowledge.

Scammers may tell you that there has been a technical issue with your account, or they may say that you need to pay for some sort of service which you did not order. They will often ask you to pay to fix the problem, and if you agree to pay the scammers, they will make it look as though you have given them the money. The scammer will then ask you to send them a new copy of your card or bank statement. In most cases, you will have sent the scammers the money, but this is just to get your money and then move on to the next victim.

Scammers will ask you for your personal information through many different channels. For example, they may send you a message on a social media site or send you a friend request. They may send you an email or message through an instant messaging application.

You should never open email attachments from anyone that you do not know or trust. If in doubt, contact the organisation that you think it is from. It is scarce for companies to actually send you attachments from their website; they will usually send you a link to the page.

Understand scam websites and what they can do

Cybercriminals use fake websites to defraud you. These fake websites look and feel exactly like the real thing. They may be based on real-world organisations, such as businesses, government agencies, or charities. However, in some cases, they are completely fake websites created by the cybercriminals themselves.

Cybercriminals may pose as an online bank, an online travel agency, a business that provides technical support, etc. Their aim is to trick you into visiting the site and giving them access to your computer or to provide them with your personal information.

Some cybercriminals will request your personal information, such as your address or your date of birth, and they may request you to pay before they provide this information. They may even ask you to visit a website or download a programme and then try to get your personal information.

You should never visit a website that is not a valid and trusted domain. To check if a website is valid, simply look up its domain. If the domain is not registered, then the website is fake. Make sure that you do not visit an unknown website or open an unknown attachment that you find on email or social media. If you are unsure, contact the website or the organisation or person that sent the email.
