  "summary": "Ukrainian hacking group Ukrainian Militant claimed on September 17 to have obtained a large cache of classified documents related to Russian naval projects. The documents, which span from 2024 to 2026, cover navigation systems for Russia's Project 636.3 Varshavyanka-class attack submarines, Project 955M Borei-A ballistic missile submarines, and Project 22350 frigates. The group, dubbed \"Poseidon,\" obtained various types of documentation, including scientific, technical, design, testing, and operational data from Russian companies developing naval systems. The materials, which reportedly include \"secret\" and \"top secret\" documents, were sourced from companies such as the Rubin Central Design Bureau for Marine Engineering. Ukrainian Militant stated that the full cache of documents is much larger than what was publicly released, covering not only navigation systems but also sonar, digital hydrography, marine robotics, and autonomous navigation for underwater vehicles.",
