Brazil's government technology provider Serpro reported record DDoS attacks over six months, with no confirmed service disruptions.

Despite claims of resilience, user reports indicated authentication issues during the same timeframe, particularly affecting digital certificate access. Serpro has not released technical details about the attacks or linked them to the reported issues. Gov.br, which supports 179.5 million accounts and over 5,000 services, remains operational according to Serpro. The attacks are part of a broader trend, with Brazil being a major target for DDoS activity, recording over 550,000 attacks in the first half of 2025. As of November 8, no Federal Police investigation has been announced, and the attackers' identity remains unknown.
