Black Friday and Cyber Monday are not only popular with shoppers, but also with fraudsters. Here are 10 tips on how to protect yourself from such scams.

Black Friday

1. Beware of Fake Websites

Fake or imitation websites are the most popular method cybercriminals use to trick online consumers into falling for their Black Friday and Cyber Monday scams. Therefore, make sure to check the provider of the site. It’s best to enter the URL manually in your browser.

2. Beware of Phishing Emails

Manipulated emails are one of the most common methods cybercriminals use to gain access to your personal data and financial information. Attackers send phishing emails to trick online shoppers into clicking on a link that appears to be from a reputable retailer. For this reason, you should not click on any links (see 1.).

3. Watch Out for Pop-ups and Ads

Emails are not the only way for cybercriminals to lure you. Pop-ups and advertisements can also be used to spread malware. If you click on such malicious ads, you might be redirected directly to a fraudulent website or download malware to your device. Therefore, do not click on any ads!

4. Use Secure Websites

How can you check if a site is secure? Buy where you normally buy and hover your mouse over the URL and check the authenticity of the web address. Look for the padlock icon in the address bar and make sure the URL starts with “HTTPS://֨” and not “HTTP://”. The “S” indicates that the website is encrypted and secured with an SSL certificate.

5. Use Your Credit Card

It is recommended to use credit cards instead of debit cards when shopping online, as the former offer additional protection. PayPal and similar providers are also suitable, as money can be recovered in the event of fraud.

6. Use Unique, Strong Passwords

It is advisable to use unique and strong passwords for any online account. You can use a password manager to create unique and strong passwords for all your accounts and store them securely so you don’t have to remember them. Never use your e-banking or company account password.

7. Use a Secure Network (Wi-Fi)

When shopping online, make sure you use a secure Internet connection, either through your phone’s cellular network or a private Wi-Fi connection. Public Wi-Fi networks often do not require authentication to establish a network connection, allowing cybercriminals to gain direct access to devices on the same open network. In this way, hackers can steal sensitive information.

8. Keep Software and Antivirus Software Up to Date

Before you start looking for the best Black Friday and Cyber Monday deals, make sure that any software is up to date. This will prevent cybercriminals from gaining access to your device through vulnerabilities in older and outdated systems.

9. Monitor Your Bank Accounts and Statements

Regularly check your bank statements to make sure that no unusual transactions have been made on your account. Cybercriminals hope that unusual debits from the account will go undetected.

10. Beware of Social Media Scams

Social media scams are very common on Black Friday and Cyber Monday. Cybercriminals use social media platforms such as Facebook, Instagram and Twitter to post and trick online shoppers into liking, sharing and clicking on malicious links to their posts.
