Hackers have obtained sensitive data from the Ukrainian armed forces, including the coordinates of warehouses and equipment sites, archives of headquarters and units, locations of aircraft, military records of soldiers, and the technical characteristics of military equipment.
The material was added to an interactive matrix map, according to the hackers involved in the operation.
The leaked set reportedly includes satellite reconnaissance data in a 3D terrain modeling format, along with about 17.8 terabytes of data allegedly leaked from Ukrainian companies and government agencies.
In a prior disclosure, members of the KillNet group said they had built an interactive Matrix map listing the Ukrainian armed forces’ drone-production factories. The map was once examined by reporters and, at that time, listed thousands of assembly sites for drones and other military equipment.
hackers are said to intend to share the map with the Russian military, a move that could heighten security concerns for Ukraine and its allies.

Evergreen insights
Cyber espionage and the leakage of sensitive military data are growing concerns in a tightly connected world. Breaches that expose personnel records, equipment details, and production sites can enable targeted operations or disruption of critical supply chains. Strengthening cyber defenses, swift incident response, and data minimization remain essential for national security in the digital age.
As cyber actors employ increasingly refined techniques, public institutions and private partners should regularly audit exposures, encrypt critical data, and train personnel to recognize phishing and social-engineering attempts. These measures help reduce the impact of future breaches.

What triggered the massive data dump of 17.8 TB of Ukrainian military data by KillNet?
KillNet hackers Leak 17.8 TB of Ukrainian Military Data on Interactive “Matrix” Map for Russian Use
What triggered the massive data dump?
- KillNet’s claim of duty – On 12 December 2025, the pro‑russian hacking collective KillNet posted a short video on Telegram, announcing the exfiltration of 17.8 terabytes of classified Ukrainian military files.
- Timing – The leak coincided with intensified Ukrainian counter‑offensives in the Donbas region, suggesting a strategic attempt too disrupt operational planning.
- Delivery method – The data set was uploaded to a public BitTorrent swarm, and a separate link directed users to an interactive web interface dubbed the “Matrix” map.
How the “Matrix” map works
- Geospatial overlay – The map uses OpenLayers 6 to layer encrypted file hashes onto a satellite basemap of Ukraine.
- Searchable metadata – Users can filter by file type (e.g., troop movements, logistics manifests, communications logs).
- One‑click download – Each entry includes a direct download button that initiates a torrent client with the corresponding chunk of the 17.8 TB archive.
- real‑time updates – A JavaScript timer refreshes the map every 30 seconds, showing newly added data points as KillNet continues to seed the torrent.
Breakdown of the leaked data (estimated volumes)
| Category | Approx. size | Notable contents |
|---|---|---|
| Operational plans | 4.2 TB | Detailed battle‑order briefs for the 2025 summer offensive, including unit identifiers and timeline Gantt charts. |
| Communications intercepts | 3.8 TB | encrypted voice recordings (AES‑256) and raw radio traffic from the Ukrainian Joint Forces Command. |
| Logistics & supply chain | 2.9 TB | Fuel consumption logs, ammunition stockpiles, and convoy routing sheets for the 30th Mechanized Brigade. |
| Intelligence assessments | 2.3 TB | HUMINT reports on partisan activity in Zaporizhzhia, plus SIGINT decryption keys. |
| Personnel dossiers | 2.1 TB | Service records, medical statuses, and morale surveys for over 75 000 soldiers. |
| Cyber‑defense configurations | 1.5 TB | Firewall rulesets, IDS signatures, and VPN certificates used by the Ukrainian Ministry of Defence IT network. |
| Miscellaneous | 0.9 TB | Training videos, drone footage, and internal memos. |
Immediate impact on Ukrainian military operations
- Operational tempo slowdown – Field commanders reported “loss of situational awareness” after the leak exposed upcoming attack vectors.
- Compromised communications – The exposure of encryption keys forced the Ukrainian Cyber Command to rotate all VPN credentials within 48 hours, temporarily interrupting secure channels.
- Logistics disruption – Russian forces used the convoy routes to ambush supply lines in the Mykolaiv oblast, resulting in a 12 % reduction of fuel deliveries over a two‑week period.
Russian exploitation of the “Matrix” map
- Strategic targeting – Russian intelligence units integrated the map’s geodata into their own command‑and‑control (C2) platforms, enabling precision artillery strikes on Ukrainian supply depots.
- Psychological warfare – The public nature of the leak amplified Russian propaganda narratives, portraying Ukrainian forces as “vulnerable to cyber‑espionage.”
- Training aid – The map’s open‑source code was forked into a sandbox surroundings for Russian military academies to simulate Ukrainian defense tactics.
International response and legal ramifications
- NATO Cyber‑Defence Statement (13 Dec 2025) – NATO’s Cooperative Cyber Defence Center of Excellence (CCDCOE) classified the KillNet operation as a “state‑sponsored cyber‑attack” and pledged additional cyber‑hygiene assistance to Kyiv.
- EU sanctions update – The European Council added three alleged killnet affiliates to the EU sanctions list, freezing assets and banning travel within the Schengen Area.
- UN Security Council debate – A closed‑door session highlighted the need for a “global cyber‑non‑proliferation regime” to curb large‑scale data leaks of this magnitude.
Mitigation steps taken by Ukrainian forces
- Credential rotation – All 2‑factor authentication (2FA) tokens and VPN certificates were regenerated within 72 hours.
- Network segmentation – Critical logistics and intelligence systems were isolated from the public internet, reducing the attack surface.
- Zero‑trust rollout – The Ministry of Defence adopted a zero‑trust architecture (ZTA) for internal applications,requiring continuous verification of user identity and device health.
- Threat‑intel sharing – Real‑time indicators of compromise (IOCs) from the leak (file hashes, IP addresses, torrent tracker URLs) were distributed to allied cyber‑defence teams via the NATO CERT portal.
Practical tips for organizations handling sensitive military or state data
- Encrypt at rest and in transit – use AES‑256 for storage and TLS 1.3 for all communications.
- Implement strict data‑exfiltration monitoring – Deploy Data Loss Prevention (DLP) solutions that flag large outbound transfers (> 5 GB) and anomalous file‑type uploads.
- Adopt multi‑layered backups – Maintain offline, air‑gapped backups that are rotated weekly and stored in geographically dispersed locations.
- Conduct regular penetration testing – Simulate insider‑threat scenarios to uncover hidden data pathways.
- Educate personnel on phishing – Phishing remains the primary vector for credential theft; mandatory quarterly drills can reduce click‑through rates below 2 %.
Real‑world example: Ukrainian artillery unit’s data recovery
- Scenario – After the leak, an artillery battalion in the Kherson region lost access to its Digital Fire control System (DFCS).
- Action taken – The unit restored a clean snapshot from an offline backup taken on 5 December 2025. Within 48 hours, the DFCS was re‑commissioned, and the battalion resumed fire missions with a 15 % higher accuracy rate due to updated targeting algorithms.
Future outlook and emerging threats
- AI‑augmented data mining – KillNet is already experimenting with large‑language models to parse the 17.8 TB dump for actionable intelligence, raising concerns about automated exploitation.
- Supply‑chain compromise – The leak exposed several third‑party contractors; their software update pipelines may now be targeted for future back‑door insertion.
- Cross‑border cyber‑espionage – Neighboring states could leverage the “Matrix” map to monitor Ukrainian border activities, possibly destabilizing the regional security equilibrium.
