Description

On October 6, 2023, around midday, the Câmara Municipal de Salvador (CMS) detected suspicious activity records within the technological infrastructure hosting its official portal. The organization attributed this attempted cyberattack to the international collective Anonymous. Upon identifying the incident, CMS immediately implemented all applicable response protocols. The Technical Team of the Legislative House's Information Technology Secretariat executed necessary measures to restore services to the www.cms.ba.gov.br portal after confirming its unavailability. Officials emphasized that no integrity compromises, data leaks, or availability impacts occurred to their corporate systems, which remained fully operational throughout the event. A published statement confirmed the swift containment response and assured continuous public access to legislative information through alternative corporate channels.

The attack attempt reportedly stemmed from motivations related to protesting sexual harassment cases in Brazilian universities, with perpetrators seeking to pressure legislative bodies nationwide to establish a Parliamentary Commission of Inquiry (CPI) on sexual harassment. This incident aligns with historical patterns of municipal legislative targets, including Teresina's Chamber website compromise in August 2022 that triggered "Access Denied" errors until technical restoration, and Belo Horizonte's 2021 portal outage that necessitated YouTube livestreams for public meeting access until full website recovery. Salvador's technical team maintained uninterrupted internal operations while restoring public portal functionality, mirroring previous municipal responses that prioritized service continuity through alternate platforms during infrastructure disruptions. The organization's transparency regarding incident timelines and containment outcomes reflected established protocols from prior regional cybersecurity events affecting legislative digital services.
