Have you ever imagined your company shutting down for days because of a cyberattack? Or having data leaked and publicly exposed, resulting in financial losses and damage to your reputation?

Brazil is among the 10 countries that suffer the most attempted cyberattacks in the world. The truth is that many organizations only realize the seriousness of the threat when they have already been affected.

In this article, you will understand what the most common cyberattacks against companies in Brazil are, the real impacts caused by these threats, and what you need to do to protect your operation quickly.

Why are cyberattacks on the rise?

The advancement of digitalization and the increasing use of cloud systems, remote devices, and sensitive data have made Brazilian companies more vulnerable and, at the same time, more attractive to cybercriminals. The result?

Millions of reais in losses, service disruptions, data loss, and even legal sanctions for non-compliance with the LGPD (Brazilian General Data Protection Law).

What are the most common types of cyberattacks in Brazil?

Protecting yourself starts with knowing your enemy. Below are the main types of cyberattacks that affect businesses, such as:

Phishing

Phishing occurs through emails, messages, or fake websites that mimic legitimate pages to capture sensitive data, such as passwords and banking information; just a few careless clicks are enough to compromise the entire network.

Ransomware

Ransomware hijacks company data, encrypting everything and demanding payment in exchange for its release. Often, even after payment, the data is not fully recovered. In Brazil, this type of attack is growing at an alarming rate.

DDoS attacks

The goal is to overload servers with a large volume of requests, taking systems and websites offline. Companies that depend on 24/7 availability, such as e-commerce businesses, fintechs, and logistics operators, are frequent targets.

Malware and Spyware

Malicious software that silently installs itself on the network; malware performs destructive or controlling actions, while spyware collects information and monitors usage without consent.

Internal data leak

Often caused by human error, carelessness, or malicious intent on the part of employees, it is one of the most difficult types to detect and can compromise strategic and confidential information.

This reality reinforces the idea that understanding the local landscape and adopting cybersecurity strategies tailored to each sector is the first step in preventing losses and maintaining business continuity.

What are the new trends in cyberattacks in 2025?

Technological advancements have also brought new forms of digital threats. Understand the main trends that should concern companies:

  • Deepfake scams

Criminals have been using deepfakes to impersonate executives, solicit financial transfers, and convincingly deceive teams.

  • API attacks

Attacks on APIs allow unauthorized access to sensitive data and even control of entire applications.

  • Supply chain attacks

Criminals don't directly attack the target company, but rather a supplier, partner, or third-party software provider with access to its network. By compromising one link in the chain, the attacker can infiltrate and target multiple organizations simultaneously.

Although these attacks are becoming increasingly sophisticated, today, technological solutions are able to identify, block, and respond quickly to these threats.

How can your company protect itself from cyberattacks?

Protection doesn't begin at the moment of attack; it's built beforehand, with technology, processes, and culture.

The foundation of a good digital defense includes:

  • Firewall state-of-the-art
  • Authentication on all access points
  • Backup automatic and encrypted
  • Real Time continuous network (24/7)
  • Training regular for all employees

In these critical moments, having a specialized company makes all the difference; it guarantees precision, speed, and the right decisions when every second counts.
