Russian President Vladimir Putin has issued a chilling warned about the "real aggression" of his enemies as he delivered a speech to his Security Council in Russia.
The leader claimed that there had been a surge in foreign attacks against Russia since the beginning of his "special operation" in Ukraine.
In the address, he warned that the attacks had not come from individual hackers but rather from state players.

Putin said Russia's financial and media institutions were among the facilities that fell victim to the hits.
The Kremlin leader claimed that the attacks had failed and called for Russia to improve its cyber security by cutting the risk of using foreign software and hardware.
He said: "Purposeful attempts are being made to disable the Internet resources of Russia's critical information infrastructure."
The news follows claims that Russian tech terrorists threatened to shut down ventilators in British hospitals at the start of May.
It came a few days after an alleged cybercriminal and supporter of Kremlin chief Vladimir Putin was arrested in the UK on May 1.
According to reports, the accused, who is said to be London-based, was detained after a police raid in the aftermath of a cyber assault on government and media websites in Romania.
He was reportedly a member of hacking group Killnet, which has since warned it will disable NHS ventilators and those in Romania and Moldova if he is not released.
The 'gang' has claimed responsibility for the attacks committed in retaliation for the country's support for Ukraine.
The official government webpage and defence ministry were targeted, as well as political parties and other companies.
A source told The Sun : "The UK has robust cyber security measures in place and, working with partners, the NCA would lead an appropriate response to any cyber crime incident having a significant impact on the UK."
It comes after the world's top intelligence alliance warned last month that Russian hackers are plotting cyber attacks on the NHS, nuclear power plants and Whitehall ministries.
The Five Eyes security network - involving the UK, US, Australia, Canada and New Zealand - issued an alert accusing the Russian government of exploring options for potential web assaults against critical organisations.
The spy coalition urged them to bolster cyber defences as they face a heightened risk of Kremlin-sponsored attacks.
According to the alert, "evolving intelligence" suggests hackers within the Russian government are seeking to engage in "malicious cyber activity" in response to the "unprecedented economic sanctions" imposed on Russia following its invasion of Ukraine.

According to the alert, "evolving intelligence" suggests hackers within the Russian government are seeking to engage in "malicious cyber activity" in response to the "unprecedented economic sanctions" imposed on Russia following its invasion of Ukraine.
There is also concern that hackers are targeting critical infrastructure in countries that have provided "materiel support" to Ukrainian forces.
