Cyber War — Russia vs Ukraine Tracker
Russia's full-scale invasion began with a wave of cyberattacks hours before the first missiles. Since then, Russian state hackers (Sandworm, APT28, Cozy Bear) have conducted over 5,000 documented attacks on Ukraine while Ukraine's IT Army — 300,000+ volunteers — hit back against Russian banks, infrastructure, and state media.

🎯 Target: Ukrainian government websites (70+ sites defaced)
🔧 Method: WhisperGate wiper malware + web defacement
Cabinet of Ministers, Foreign Ministry, Education Ministry sites defaced. "Be afraid and expect the worst." Data wiper deployed on Ukrainian systems — disguised as ransomware.
Attribution: Microsoft MSTIC, CISA attributed to GRU-linked actors
🎯 Target: Ukrainian military, government, financial institutions
🔧 Method: HermeticWiper, IsaacWiper — data destruction malware
Destructive wiper malware deployed across hundreds of Ukrainian systems hours before invasion. Designed to brick devices permanently. Coordinated with military offensive.
Attribution: ESET, Symantec, SentinelOne; attributed to GRU
🎯 Target: Viasat KA-SAT satellite communications network
🔧 Method: AcidRain wiper targeting satellite modems
Took down ~40,000 satellite modems across Europe. Ukraine's military relied on Viasat for communications — lost connectivity for hours on invasion day. Spillover affected wind turbines in Germany.
Attribution: US, UK, EU jointly attributed to Russia (GRU); confirmed May 2022
🎯 Target: Ukrainian energy company (Ukrenergo substation)
🔧 Method: Industroyer2 — ICS/SCADA-targeting malware
Attempted to shut down high-voltage electrical substation in Ukraine. CERT-UA and ESET detected and neutralized before execution. Most sophisticated ICS attack since original Industroyer (2016).
Attribution: CERT-UA + ESET joint investigation; GRU Unit 74455
🎯 Target: NATO countries' government sites (USA, Germany, Italy, Romania, Latvia)
🔧 Method: DDoS attacks
Temporary disruptions to government websites in multiple NATO states. More noise than effect — politically symbolic rather than operationally significant.

🎯 Target: Russian banks, government sites, state media (TASS, RIA Novosti)
🔧 Method: Coordinated DDoS; data leaks
Temporary disruption of Sberbank, VTB, Russian state television portals. Sberbank reported largest DDoS in its history. IT Army grew to 300,000+ volunteer participants globally.
Attribution: Ukraine IT Army — Telegram-coordinated volunteer hacktivist collective, guided by Ukraine SSSCIP
🎯 Target: Ukrainian and European energy sector
🔧 Method: Spearphishing, credential theft, network intrusion
Reconnaissance of European energy suppliers providing aid to Ukraine. Pre-positioning for potential disruption during winter energy crisis. Detected and disrupted by national CERTs.
Attribution: NSA, CISA joint advisory; APT28 (GRU Unit 26165)
🎯 Target: Kyivstar — Ukraine's largest mobile network (~24M subscribers)
🔧 Method: Long-dwell network intrusion; wiper malware
Complete destruction of Kyivstar's core infrastructure. Network down 2+ days. 24 million Ukrainians without mobile service. No voice, SMS, or mobile internet. Air raid warning systems disrupted in some areas.
Attribution: Ukrainian SBU directly attributed to Sandworm (GRU). Kyivstar CEO confirmed Russian military hackers.
🎯 Target: M9com — Russian internet service provider
🔧 Method: Intrusion and destructive attack
Took down M9com — major ISP serving Moscow. Disrupted internet access for thousands of Russian users and state organizations. Retaliation for Kyivstar attack.
Attribution: Ukraine's GUR (Military Intelligence) claimed responsibility
🎯 Target: Ukrainian critical infrastructure (ongoing)
🔧 Method: Espionage, wiper malware, spearphishing, supply chain
Continuous campaign: 5,000+ cyberattacks on Ukrainian government systems in 2022–23 alone (SSSCIP data). Russia shifted strategy from destructive to persistent espionage after Ukraine hardened defenses. In 2025–2026 AI-assisted spearphishing targeting Ukrainian military networks intensified.

Cyber War Lessons
Cloud Migration Saved Ukraine
Before the invasion, Ukraine moved government data to cloud (Microsoft, Amazon). Russian attacks destroyed server rooms but couldn't erase cloud backups. A critical pre-war resilience decision.
Viasat Attack Effect
The Feb 24 Viasat attack was the most consequential — it disrupted Ukrainian military comms on invasion day. SpaceX's Starlink deployment became critical as a result. A model for "D-Day" cyberattack coordination.
Ukraine's Cyber Allies
Microsoft, Google, Amazon, Cisco all provided emergency cyber defense support. EU activated its Cyber Diplomacy Toolbox. CrowdStrike, ESET deployed teams in Ukraine. Unprecedented private-sector war effort.
IT Army Effectiveness
Ukraine's 300,000-volunteer IT Army is the world's largest hacktivist force. Coordinated via Telegram, it targeted Russian banks, railways, state media. Real disruption but hard to quantify strategically.
