Brazil's Serpro faces record DDoS attacks as Gov.br remains operational
Brazilian government technology provider Serpro says its systems faced record DDoS attacks over the past six months.
DDoS attacks flood online systems with traffic to disrupt access.
Serpro says it mitigated the attacks and Gov.br remained operational, though some government services reported problems.
The Council for Financial Activities Control reported certificate-based authentication was unavailable for some users on Nov.
4 and 5, while eSocial recorded integration issues.
Neither agency linked its problems to the attacks, so their cause is unclear.
Gov.br has 179.5 million active accounts and provides access to more than 5,000 federal services, including pensions and healthcare.
Serpro signed a five-year contract worth 38.4 million reais for DDoS protection in May 2026, but has not released technical details about the recent attacks.
Serpro says its infrastructure faced record distributed denial-of-service attacks over the past six months.
Officials said the Gov.br identity platform remained operational, although some government services reported authentication or integration problems.
Serpro director Andre Picoli Agatte described a November attack as unprecedented and called for increased cybersecurity investment.
The Gov.br platform supports 179.5 million active accounts and provides access to more than 5,000 federal services.
Serpro has not released technical data on the scale or impact of the attacks.
