The defacement is a form of protest in Zambales mining.
z0mb13 who is spearheading the attack says in the deface page, “It’s too late to expect us!”
A direct message is also left in the hacked page to DENR and the Provincial Government of Zambales, “STOP MINING IN ZAMBALES.” And another to the supreme court, “Continue to issue temporary environmental protection order (TEPO) against DENR and the Provincial Government of Zambales to stop the issuance and implementation of mining permits in the country.”
Message also in the bottom hints the hackers are affiliated to the anonymous collective who opposed the legality of Cyber Crime law last year.
