Senate website as of 12:49 PM (June 11, 2026)
The Senate website was defaced in an apparent cyber incident, but authorities said there was no initial indication that sensitive or confidential data had been compromised.
The Senate Electronic Data Processing and Management Information System Bureau said the website was subjected to an unauthorized change, commonly known as website defacement.
Based on its preliminary assessment, the bureau said the affected site mainly contained documents and information already intended for public access.
The Department of Information and Communications Technology separately said the incident appeared to have been limited to the Senate website’s public-facing pages.
The DICT, however, said a full technical investigation was still underway and that final findings would be validated before conclusions were made.
A hacktivist group identifying itself as Nullsec Philippines claimed responsibility for the defacement, while cybersecurity advocacy group Deep Web Konek flagged the incident on Thursday morning.
The DICT said its National Computer Emergency Response Team had coordinated with the Senate’s data management office to contain the incident and help restore the website’s integrity.
The affected website was placed under maintenance as the DICT, the Senate, the Cybercrime Investigation and Coordinating Center, and law enforcement agencies conducted forensic checks to identify those behind the attack, who may face charges under the Cybercrime Prevention Act.
