Ukraine claims to have obtained sensitive data from a Russian strategic bomber manufacturing company.

On June 4, a source in Ukraine’s military intelligence agency (HUR) said that the agency had obtained sensitive data on Russian strategic aircraft manufacturer Tupolev. According to the source, HUR’s cyber forces accessed more than 4.4 gigabytes of the company’s internal data, including official correspondence, personnel files, home addresses, resumes, purchase records, and closed-door meeting minutes. “The importance of these data cannot be overestimated,” the source said. “Now, in fact, there are no more secrets about Tupolev’s activities for the Ukrainian intelligence agencies.” This intelligence includes details of the engineers and crews responsible for maintaining Russian strategic bombers, such as the Tu-95 and Tu-160, which are a key component of Russia’s “triad” nuclear forces. Ukrainian cyber agents also replaced the homepage of Tupolev’s website with an image of “an owl grabbing a Russian plane.”
