The cybergroup Anonymous claims to have leaked the database of the Russian Ministry of Defense website.
As Putin announced his decision to invade Ukraine on Thursday morning (February 24), the Anonymous later announced their intentions.
Later that evening, the group tweeted that it was “officially in cyber war against the Russian government”.
Within 30 minutes of the announcement, they shared that they had taken down the website of Russian-backed TV channel RT, which broadcasts in Britain.
However, it now appears that the site is back up and running, at the time of writing.
A day later, they have now claimed to have leaked a huge government database.
They tweeted: “The #Anonymous collective has leaked the database of the Russian Ministry of Defense website. #Ukraine.”
The group appears to operate on two accounts, one with 6.5 million Twitter followers.
They have been linked to online attacks around the world.
Their goal is to “punish” governments for policies the hackers disapprove of.
Ukrainian President Volodymyr Zelenskyy on Saturday renewed assurances that the country’s military would resist the Russian invasion. In a video recorded on a street in central Kyiv, he said he stayed in the city.
“We are not going to lay down our arms. We will protect the country,” he said.
“Our weapon is our truth, and our truth is that this is our land, our country, our children. And we will defend all of that.”
Mr Zelenskyy said in a second video on Saturday that Moscow’s plan to quickly seize the capital and install a puppet government had failed. In an emotional speech, he accused Russian forces of hitting civilian areas and infrastructure.
He pushed for Ukraine’s urgent membership of the European Union, saying he had discussed the issue with EU leaders.
US officials also say they believe Russian President Vladimir Putin is determined to overthrow the Ukrainian government and replace it with his own regime.
