• •Belarusian hackers infiltrated a Russian healthcare network for nearly two years.
• •The breach involved accessing sensitive medical data without disrupting operations.
• •The Cyber Partisans claim to have access to hundreds of IT systems across Russia and Belarus.

The Belarusian Cyber Partisans have claimed responsibility for a breach of Moscow's healthcare network, confirming their infiltration that began in 2023. They gained administrator-level access to the Moscow Department of Health and spent nearly two years inside the network before abandoning the operation. Russian cybersecurity firm Solar discovered the breach in December 2025, tracing it back to early 2024. The hackers accessed sensitive medical information but did not disrupt operations or destroy data. The group stated that the information obtained could help assess Russian military casualties in Ukraine. They have claimed access to hundreds of IT systems across Russia and Belarus, but this claim remains unverified. The Cyber Partisans have previously targeted Belarusian government institutions and have been designated an extremist organization by Russia's Supreme Court.
