Brazil targeted by surge in AI-enabled cyberattacks
Brazil has emerged as a significant target for cyberattacks facilitated by artificial intelligence. Reports indicate that cyberattacks enabled by generative AI grew by 89% in the first half of 2026 compared to the same period in 2025. Criminal groups are utilizing AI to bypass language barriers, create highly convincing phishing messages in Portuguese, and identify technical vulnerabilities or susceptible employees.
In June, Brazil was ranked as the third most affected country by ransomware, recording 23 cases. The use of AI allows criminals to automate technical operations and refine fraudulent schemes, making them more effective against Brazilian companies across various sectors.
Beyond external attacks, research from MIT highlights vulnerabilities within AI models themselves. A study demonstrates that AI can be
