MANILA -- "Kangkong", the data security officer of the Manila Bulletin, has claimed that he hacked 93 websites of the government and private companies.

He said he also hacked websites with servers that are located abroad. 

He left a picture in the websites that he has compromised that says “Hacked by Kangkong” as proof.

Kangkong is 24 years old, and only finished elementary-level education. 

He said he started learning how to hack when he was just 15 years old. 

“Curiosity lang talaga. Kasi nakita ko may skills ako sa pagtinker ng mga bagay. So nag-self study ako ng hacking. Inaral ko kung paano mag-hack ng website hanggang sa nakuha ko na po," he told ABS-CBN News.

In an extrajudicial confession, he alleged that it was Manila Bulletin Senior Technology Officer Art Samaniego who ordered the hacking of the Peacekeeping Operations Center website of the Armed Forces of the Philippines, the mail server of the National Security Council, and the recruitment website of the Philippine Army.

"Pag may mga website ako na hinahack sinesend ko sa kanya. Depende kung gaano kalaki ang government agency 'yun, yung titignan niya kung gagawan niya ng article. Tapos nung nagkita kami, naghahanap ako ng work, sabi niya baka pwede ako sa Bulletin," he said.

The NBI is set to subpoena Samaniego and explain the allegations.

Kangkong said he is asking for forgiveness for identifying Samaniego, and for all those who were affected for the websites he hacked. 

"Malaki po ang utang na loob ko sa kanya, sa nagawa niya sa akin sa Bulletin, pero sorry Sir Art na ganito ang nangyari...Humihingi ako ng paumanhin sa aking mga biktima. Lalo na kay Pangulong Bongbong Marcos. Pinagsisisihan ko ang aking ginawa," he said.

Kangkong also warned fellow hackers who are targeting government websites, especially those that involve national security.

"Nung ni-leak ko ang database ng AFP, na-realize ko yung consequences na dapat di ko ginawa kasi ang laki ng effect sa military community. Siyempre na leak ko yung data ng mga sundalo... at may foreign na tao na nakakuha noon. Doon ko narealize na mayayari tayo. Doon ko narealize na marami tayong kalabanan at hindi tayo dapat nagtitirahan sa loob," he said.

Kangkong said he wants to emphasize the lack of cyber security in government  websites and the private sector.

"Hindi po talaga priority ang cybersecurity sa Pilipinas. Dapat mag-invest sila sa security. Alam namin na mahal mag-hire ng tao, mahal ang tools na kailangan. Pero dapat mag-invest sila kahit papaano kasi kung hindi sila mag-invest at na-breach sila, mas malaki ang gagastusin nila," he said.

Samaniego earlier denied the allegations of Kangkong. 

The Manila Bulletin, meanwhile, issued a statement condemning any unauthorized access into information systems. 

They are also conducting their own probe and are wiling to cooperate with the authorities regarding the case.
