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.

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.

Frequently Asked Questions

Has Russia hacked Ukraine during the war?
Yes. Russia has conducted thousands of documented cyberattacks against Ukraine. Over 5,000 attacks on Ukrainian government systems were recorded in 2022–2023 (SSSCIP). Russian state hackers began operations months before the February 2022 invasion: WhisperGate wiper malware was deployed on January 13–14, 2022, followed by HermeticWiper and IsaacWiper deployed the night before the full-scale invasion.
What is Sandworm and what has it done in Ukraine?
Sandworm (GRU Unit 74455, aka Voodoo Bear) is the world's most destructive hacker group. Ukraine has been its primary target for over a decade. Key Ukraine operations: 2015–2016 electricity grid blackouts (first ICS attacks in history), NotPetya global wiper (2017), Viasat satellite hack on invasion day (Feb 24, 2022), Industroyer2 power grid attack (Apr 2022), and the Kyivstar mobile network destruction (Dec 2023).
What was the Viasat KA-SAT hack in February 2022?
On the morning of the full-scale invasion (Feb 24, 2022), Russian GRU hackers deployed AcidRain wiper malware against Viasat's KA-SAT satellite network, destroying ~40,000 modems. Ukraine's military lost satellite comms on day one. Spillover disrupted wind turbines in Germany and users across central Europe. The US, UK, and EU jointly attributed the attack to Russia in May 2022. It accelerated Starlink's critical role in Ukraine.
What is the Ukraine IT Army and how effective is it?
The Ukraine IT Army is a hacktivist collective launched by Ukraine's Ministry of Digital Transformation on February 26, 2022. Coordinated via Telegram, it grew to 300,000+ volunteers from 52+ countries. It conducts DDoS attacks and data leak operations against Russian banks (Sberbank, VTB), state media (TASS, RIA Novosti), and government services. Sberbank reported the largest DDoS in its history during this campaign.
What was the Kyivstar hack and why does it matter?
In December 2023, Sandworm destroyed Kyivstar's entire core IT infrastructure after months of undetected access. Ukraine's largest mobile operator (24 million subscribers) went offline for 2+ days. Ukrainians lost voice, SMS, and mobile internet. Air-raid warning systems in several areas were disrupted. The SBU attributed the attack directly to Sandworm (GRU). Ukraine retaliated in January 2024 by destroying M9com, a Moscow ISP.
