Killnet, a pro-Russian hacktivist group, released leaked stolen data on its Telegram account allegedly belonging to individuals with ties to the North Atlantic Treaty Organization (NATO).

Killnet created a dedicated channel and shared a sample of the leaked document under the title 'F**K NATO'.

Killnet claimed that it has the rest of the 100.000+ documents, presentations, descriptions of events and reports on the subject of Ukraine, details of the NATO LAWFAS portal and 100 logins and passwords of NATO military school JADL.

Threat intelligence platform FalconFeedsio reported that the stolen data referred to nearly 4639 individuals with links to NATO from US, UK, Australia and other countries.

Cybernews reported that the leaked document included a CSV file with the personal information of the individual victims, which includes their name, phone number, email address, city and country.

It is believed Killnet leaked the document to coincide with the visit of NATO Secretary General Jens Stoltenberg to Kyiv.
