MANILA, Philippines – At least three websites or services connected to the Department of Science and Technology (DOST) were defaced on Tuesday, April 2.

The affected links were https://helpdesk.dost.gov.ph, http://hta.dost.gov.ph, and https://sfu.dost.gov.ph.

Aside from the DOSTs help desk, its Health Technology Assessment division and its S&T Foundation Unit were the other defaced websites within the roster.

As with the case of an earlier attack on a number of company websites linked to House Speaker Martin Romualdez, these appear to have been done by the entity known as “ph1ns” as part of the supposed #opEDSA campaign.

The attacks were verified by way of archived pages of the sites on the Wayback Machine. The defaced DOST websites were also sporting the same #opEDSA messages from the attacked company websites linked to Romualdez, calling for an end to charter change and political dynasties.

The three websites remain offline and inaccessible as of posting time.

According to a Manila Bulletin report, sources at the Department of Information and Communications Technology (DICT) said the hackers also deleted 25 terabytes of data.
