Microsoft Probes Cyber Leak, Examines Chinese Hacking Links

Microsoft is investigating a potential leak from its Microsoft Active Protections Program (MAPP). Security vulnerability information may have alerted Chinese state-linked hacking groups to exploit a critical SharePoint server vulnerability starting in July 2025.

No official statements were made by Microsoft’s leaders. A blog acknowledged the exploit by these groups but did not attribute it to a specific leak. The groups involved are suspected Chinese state affiliates known for espionage and intellectual property theft.

The incident concerns an enterprise software vulnerability with no direct impact on cryptocurrency markets. No asset liquidations or funding changes were observed, and no affected cryptocurrency assets such as ETH, BTC, or altcoins were confirmed.

There have been no noticed responses from major cryptocurrency exchanges. No alerts or operational changes have been reported. On-chain analytics did not link the incident to any systemic crypto infrastructure risk or protocol exploitation.

This incident echoes the 2021 Microsoft Exchange “Hafnium” hack, involving Chinese state-affiliated actors. Both targeted enterprise server software but did not directly impact cryptocurrency assets, focusing instead on corporate data infrastructure.

Kanalcoin experts suggest that current data shows no systemic risk to the crypto sector. There might be indirect impacts if exploits reach exchanges or custodians, but no such chain reactions are evident in on-chain or market data.
