Russian sources say President Vladimir Putin has increasingly been spending nights inside the Kremlin amid heightened concerns for his personal security.
The claims come from the Telegram channel VChK-OGPU and the Rucriminal website, both of which cover security-service developments in Russia.
Those outlets report that mobile internet access has been restricted across Moscow amid fears that adversaries may have compromised parts of the state's surveillance network, including CCTV systems in the capital.
The alleged steps are described as precautionary measures taken while the security services investigate the potential breach.
Some commentators have compared the situation to a recent high-profile security incident in Tehran, but such parallels and the underlying details remain unverified by independent sources.
Authorities have not publicly confirmed the specific security concerns cited in the reports.
The same sources add that Telegram has been blocked in areas along Russia’s frontline in Ukraine, a move that would affect a widely used channel of communication for troops.
The reports mark a sharp uptick in alarm among parts of Russia’s security establishment and underline ongoing tensions over digital vulnerabilities.
These accounts are still emerging and have not been independently corroborated.
More information is likely to follow as reporters seek confirmation and official responses.
