Brazil as the preferred target in Latin America
Between July and December 2025, Brazil recorded 470,677 Distributed Denial of Service (DDoS) attacks. This volume represents nearly half of all incidents recorded in Latin American territory during the same period. This data is not just a traffic statistic, but a critical indicator that the national infrastructure has become the favorite target for groups seeking extortion, hacktivism, or the destabilization of essential services.
Why the scenario escalated in 2025
The country's high connectivity, combined with increasing dependence on online services and the massive volume of vulnerable IoT devices, created the ideal environment for botnet proliferation. Home networks and smart devices without proper hardening are routinely hijacked to serve as vectors in large-scale attacks. This explosive growth forced a state response, culminating in Provisional Measure 1,317/2025, which aims to transform the ANPD into an independent regulatory agency with greater powers for inspection and punishment.
The anatomy of the attack in practice
Unlike intrusions focused on silent data theft, DDoS aims at resource exhaustion. In our Red Team operations, we observe that attackers use multiple simultaneous techniques:
- Bandwidth Exhaustion: Flooding UDP or ICMP packets to saturate the communication link.
- Application Layer Attacks: Complex HTTP requests designed to exhaust CPU and memory on database servers.
- Camouflage Attack: Using volumetric DDoS as a smokescreen to distract Blue Teams while data exfiltration occurs through another vector.
Real impact on attacked sectors
The telecommunications sector leads the targets, followed by financial services and cloud providers. A loss of availability in these segments does not only generate immediate financial loss, but also severe reputational damage and, with the new ANPD stance, risks of heavy administrative sanctions for failure to protect the infrastructure supporting data processing.
How to establish a resilient defense
Mitigating attacks that reach peaks of hundreds of Gbps requires more than conventional firewalls. Defense must be structured in layers:
- Scrubbing Center Implementation: Diverting suspicious traffic to cleaning centers before it reaches the internal network.
- Rate Limiting Policies: Strict control of requests by IP and traffic behavior at layer 7.
- Continuous Monitoring and Threat Intelligence: Proactive identification of known botnet signatures for preventive blocking.
The Antisec Perspective
In our penetration tests and adversary simulations, we frequently identify that the greatest vulnerability is not the volume of the attack, but the lack of a tested incident response plan. We have simulated scenarios where the client's mitigation infrastructure was misconfigured, allowing low-volume attacks to cause total outages in critical systems. Availability is the first pillar of information security.
Conclusion: The regulatory urgency
The 2026 landscape no longer allows for amateurism in network asset management. With the ANPD gaining regulatory agency autonomy, negligence regarding DDoS attacks can be interpreted as a lack of technical diligence in protecting business continuity. The risk is real, immediate, and measurable.
