In recent days, the US Justice Department and Pentagon have begun investigating an apparent online leak of sensitive documents, including some that were marked “Top Secret”. A portion of the documents, which have since been widely covered by the news media, focused on Russia’s invasion of Ukraine, while others detailed analysis of potential UK policies on the South China Sea and the activities of a Houthi figure in Yemen. The existence of the documents was first reported by the New York Times after a number of Russian Telegram channels shared five photographed files relating to the invasion of Ukraine on April 5 – at least one of which has since been found by Bellingcat to be crudely edited.

Russia’s further invasion of Ukraine in February 2022 was a watershed moment, and unique in that a major nation-state had engaged in coordinated, convergent digital and physical attacks in an effort to conquer a neighboring country. Leaders will draw lessons from this conflict for years, but one is already clear: the ability to deliver cyber defense assistance must be a key national security capability.

The Ukraine war has inspired a defensive cyber effort that government officials and technology executives describe as unprecedented.

Ukraine has achieved a cut-price version of what the Pentagon has spent decades and billions of dollars striving to accomplish: digitally networked fighters, intelligence and weapons.

With the ongoing war in Ukraine, in the Polish cyberspace, there are more and more occurrences classified as computer incidents, including attacks perpetrated by Russian hackers. This is a response of the Russian Federation to the Poland’s support provided to Ukraine and an attempt to destabilise the situation in our country.
