The hacker collective Anonymous says it's launching a new campaign against Donald Trump.
"Dear Donald Trump, we have been watching you for a long time and what we see is deeply disturbing," a masked person with a computerized voice says in a YouTube video uploaded on March 4. "You have shocked the entire planet with your appalling actions and ideals."
In the unverified video bearing the hallmarks of an Anonymous production, an unidentified figure calls on 'hacktivists' to spread the word and target the Republican presidential candidate's websites.
"We need you to shut down his websites, research and expose what he doesn't want the public to know. We need you to dismantle his campaign and sabotage his brand," the speaker, whose voice is distorted, says in the video.
The online campaign has been labeled "#OpTrump," and in the comments on the YouTube video Anonymous asks hackers to target the website for Trump International Hotel and Tower in Chicago on April 1.
Anonymous is a loosely organized online group of activists and hackers, and in the past members have been involved in campaigns to take down social media accounts linked to ISIS. People affiliated with the group also claimed to have launched an attack against TrumpTowerNY.com in December.
