Anonymous claim they have hacked Russia's central bank in the latest attack in their "all out war" against Vladimir Putin.
The group said they made the attack on Wednesday evening and have threatened to release tens of thousands of secret documents to the world in the next 48 hours.
They tweeted: “JUST IN: The #Anonymous collective has hacked the Central Bank of Russia.
“More than 35,000 files will be released within 48 hours with secret agreements. #OpRussia.”
The group did not specify what the documents were of or the possible ramifications of their publication.
It added: "For the record, #Anonymous does not support any kind of political sides, or political leaders, or religion.
"We do support freedom fighters, we support citizens in any countries that are in need of help & under suppression by dictatorship.
"Revolution is now. One love."
The claim is the latest attack on Russia since the outbreak of war a month ago today when the group vowed to "punish" Moscow for its illegal invasion of Ukraine.
In the last four weeks Anonymous' cyber war on the Kremlin has also included hacking into their government's website and state-owned media channels, showing pictures of the misery caused by its soldiers in under-siege Ukraine.
The regular home pages of state news agency Tass, Kommersant and Izvestia were replaced with an anti-war messages.
The message read: "Dear citizens. We urge you to stop this madness, do not send your sons and husbands to certain death. Putin makes us lie and puts us in danger.
"We were isolated from the whole world, they stopped buying oil and gas. In a few years we will live like in North Korea.
"What is it for us? To put Putin in the textbooks? This is not our war, let's stop it!
"This message will be deleted, and some of us will be fired or even jailed. But we can't take it anymore.
"Indifferent journalists of Russia."
In another online attack Russian websites started playing traditional Ukrainian folk songs.
Anonymous declared taking the sites offline as a "present" to Putin after he ignored their earlier demands to resign and restore the rights of the Ukrainian people.
In a message directly aimed at the Russian President, a member of the hacking group said: "We have been patently waiting for you to respond to our most recent request, but we find ourselves growing impatient of your foot dragging.
"Unfortunately it seems you have made the option to ignore our presence and therefore we have decided to dedicate and operation specifically for you.
"A present of sorts."
