Next Friday, November 24th, is Black Friday. Among the “madness” of discounts and promotions, threats also hide and Cipher, the cybersecurity division of the Prosegur Group, warns of the proliferation of malicious apps.
According to experts, malicious app creators take advantage of occasions such as Black Friday, or even Cyber Monday, to attract more traffic and increase the number of downloads. Alongside malicious apps, Cipher warns that among the most common attack strategies during this period are website forgery, malvertising and phishing.
With a huge increase in e-commerce sales and post-pandemic remote work, consumers should be more concerned than ever about fraud threats hidden on Black Friday.
Cloning legitimate websites is one of the techniques frequently used by cybercriminals to collect victims' personal information, as well as credentials and banking details. The stolen data is sold on forums on the Dark Web, or used in social engineering attacks.
When it comes to malvertising, Cybercriminals use online advertisements to distribute malicious software or redirect user traffic. Cipher explains that in these cases, hackers introduce “contaminated” ads into legitimate advertising networks that display ads on trusted websites
During times like Black Friday it is common to receive a greater number of emails and SMS messages regarding brand promotions and discounts. It is very common for cybercriminals to take advantage of this scenario to resort to phishing tactics and “disguise” fraudulent messages.

“With the likelihood of an increase in fraud during Black Friday, Cipher recommends consumers to pay maximum attention, especially when looking for offers in sectors such as technology, fashion and accessories”, indicate the experts.
