MANILA, Philippines — The Senate on Thursday confirmed that its official website was recently subjected to an “unauthorized modification” or website defacement but said that initial assessment showed “no indication that confidential or sensitive information had been compromised.”
Sen. Vicente Sotto III, when asked if the defacement of the website could be part of the reported threat against the chamber, said: “I don’t know … could be. Anything to hurt the Senate probably.”
In a statement, the Senate, through its Electronic Data Processing-Management Information System (EDP-MIS) Bureau, said its technical team has launched a comprehensive investigation to determine the cause and extent of the unauthorized activity.

“Upon detection of the incident, our technical team immediately initiated security protocols, contained the issue, and commenced a comprehensive investigation,” it said.
“Additional security measures are also being implemented to prevent similar incidents from occurring in the future,” it added.
The website primarily contains publicly available documents and informational materials intended for public access.
“We assure the public that protecting the integrity and availability of our systems remains a top priority. We continue to closely monitor the situation and will provide updates as necessary,” the EDP-MIS Bureau added.
Hacker’s warning
On Facebook, a group called “Nullsec Philippines” claimed responsibility for defacing the website, warning that it was “watching” the Senate.
“The Filipino people entrusted you with power, responsibility, and the duty to serve the nation—not personal interests, political dynasties or corrupt networks,” it said. “Every peso lost to corruption is a meal taken from a family, a classroom left unfinished, and a future denied.”
“Transparency is not optional. Accountability is not negotiable. Public office is not a shield from scrutiny,” the group added.
“To those who serve with integrity, continue your work. To those who abuse the public’s trust, know that citizens are paying attention. The people deserve the truth,” the group said.
