Criminals often use deceptive tactics to steal consumers’ personal and financial information. Therefore, it is crucial to remain vigilant and adopt safe practices when browsing and making transactions on the internet.

Stay away from fake or cloned websites

During Black Friday, scammers often create fake or cloned websites that mimic legitimate stores to trick consumers. These sites may look nearly identical to the originals, but minor details such as spelling mistakes in the URL or the absence of “https” in the address may indicate that something is wrong. For example, criminals may create links that resemble those of famous stores, such as “Amazon.com" or "Magazineluiza.com.br“, but with small changes, like a “M” extra at the end of “Amazon” or with an ending other than “. Com.br".

Criminals use these sites to steal personal and financial information by tricking consumers into making purchases or entering personal information. To protect yourself, always double-check the website address for any errors or subtle differences. Instead of clicking on links sent to stores via email or text message, it’s best to visit the store’s website directly.

Another way to check the security of the site is to click on the “website information” in the address bar and look for the icon padlock with the information “the connection is secure“Using reliable search engines to find the store’s official website and checking digital certificates and security seals also helps confirm the site’s legitimacy. See the example below:

Be wary of websites that offer absurdly low prices or very advantageous payment terms. Never enter personal or financial information on websites that you are not sure are safe and legitimate.

Phishing via email or WhatsApp

Phishing generally works by sending emails or messages. WhatsApp that appear to come from trusted sources, such as banks, well-known stores, or even friends. These messages often contain malicious links that direct the user to fraudulent pages asking for sensitive information. To avoid falling for this type of scam, never click on links or download attachments from unknown senders. Always check the sender's address and, if in doubt, contact the company or person who supposedly sent the message directly.

Another important tip is to keep an eye out for spelling or grammar mistakes in messages, as these are often a sign of phishing. Let's look at one below: example of a phishing scam message sent via WhatsApp during the Black Friday:

"Reclame Aqui", as consumers share their experiences and reviews. When consulting the "Reclame Aqui", you can identify whether the store has a lot of complaints, what the nature of those complaints are, and how the company resolved them. Stores with a high rate of problem resolution tend to be more trustworthy. This prior research can help you avoid headaches and ensure that you are dealing with a legitimate seller.

If you find many unresolved complaints or recurring problems, consider looking for another seller. If you have already been harmed by them, you can even file your own complaint by clicking the button. COMPLAIN in red.

Check for fake security seals and HTTPS.

Scams involving fake security seals have become common during the Black FridayThis is especially true on websites designed to deceive unsuspecting consumers. Scammers replicate icons such as "Secure Site," "Protected Purchase," or seals from well-known companies, applying copied images without any real validation. Visually, these seals appear legitimate, but they have no connection to security systems or audits.

Another common scam is that of HTTPS This is false, as it exploits the belief that any website with a "padlock" icon is secure. Although... HTTPS While important, it only indicates that there is encryption in the connection between the user and the website—not that the website belongs to a reputable company. Criminals can easily issue basic certificates, causing fraudulent pages to display the padlock in the address bar, deceiving consumers who use this single criterion to measure the trustworthiness of a store.

To identify these scams, it's essential to go beyond the visual aspect. For security seals, click on them to verify if they lead to an official page confirming certification; fake seals usually don't have a link or lead to generic pages. In the case of... HTTPSWhen checking, make sure the address is actually the brand's official domain, without strange variations, random numbers, or spelling errors.

Scammers infiltrate these groups to trick members and steal their personal and financial information. Before clicking on any link, make sure the source is trustworthy and that the link leads to a legitimate website.
