MANILA - The National Union of Journalists of the Philippines (NUJP) said its website was targeted by a denial of service (DoS) attack on Monday night.

The NUJP website is no longer accessible as a result.

In a DoS attack, the perpetrator makes a network resource unavailable by disrupting services of the host connected to the Internet.

In a statement, NUJP condemned the attack, calling the perpetrators "enemies of press freedom and free expression."

"They are vermin, narrow-minded, misbegotten souls who mistakenly believe that they can silence critical speech and thought in their desire to force people into accepting only one worldview – theirs," NUJP said.

NUJP said they will not be cowered by the attack.

"The independent Philippine press, the independent Filipino journalists, and the freedom-loving Filipino people will make sure of this, as we have done in the past and as we will do so again and again whenever basic rights and liberties are assaulted," the group said.
