MANILA - The Commission on Elections (Comelec) has asked the National Bureau of Investigation (NBI) Cybercrime Division to identify the perpetrators of the hacking of the poll body's official website.

A group claiming to be Anonymous Philippines defaced the Comelec's website Sunday evening, demanding that the poll body implement the security features of the vote counting machines for the May 9, 2016 elections.

Meanwhile, another group named LulzSec was able to upload 340 gigabytes of "stolen" Comelec database on their Facebook page.

Jimenez said the Commission's IT Department has been working to restore the full functionalities of the Comelec website as several of its apps were affected by malware.

On Tuesday morning, users were not able to access the site entirely as it was still undergoing "cleanup."

Jimenez said the hackers did not get classified information since the database is already available to the public. There were also no signs that hackers were able to obtain sensitive biometrics data from the voters database.

"The database is intact, walang nagbabago," Jimenez added, explaining that vital election information has already been uploaded into the Election Management System for the automated elections.
