Anonymous, an international hacking collective that has conducted cyberattacks against governments and corporations, appeared to declare war against Putin and Russia due to its invasion of Ukraine. 

The "YourAnonNews" Twitter account, which boasts 6.5 million followers, made the declaration on Thursday, saying that the hacking group is "currently involved in operations against the Russian Federation."

"We want the Russian people to understand that we know it's hard for them to speak out against their dictator for fear of reprisals," the decentralized hacking collective said.

"We, as a collective want only peace in the world. We want a future for all of humanity. So, while people around the globe smash your internet providers to bits, understand that it's entirely directed at the actions of the Russian government and Putin."

RT.com, a Russian government-funded media outlet that the U.S. State Department describes as a critical element in "Russia’s disinformation and propaganda ecosystem," said that it was targeted in what appears to be a widespread denial-of-service (DDoS) attack. 

A DDoS attack is a coordinated effort to knock a website offline by flooding it with traffic.
