According to the source, HUR's cyber corps accessed over 4.4 gigabytes (GB) of internal data, including official correspondence, personnel files, home addresses, resumes, purchase records, and closed meeting minutes.

"The significance of the data obtained cannot be overestimated," the source said. "Now, in fact, there is nothing secret left in Tupolev's activities for Ukrainian intelligence."

The intelligence includes detailed information about engineers and staff responsible for maintaining Russia's strategic bombers, such as the Tu-95 and Tu-160, which form a key part of Russia's nuclear triad.

"In particular, we have obtained comprehensive information about individuals directly involved in servicing Russian strategic aviation," the source added. "The result will obviously be noticeable both on the ground and in the sky."
