Beijing, March 7, 2025 – China-linked Silk Typhoon is exploiting IT supply chains, using zero-day vulnerabilities, stolen API keys, and cloud breaches to target global enterprises.
A new wave of cyberattacks has rocked global IT infrastructure as Silk Typhoon, a China-linked hacking group, shifts its focus to IT supply chains. This highly sophisticated cyber espionage campaign is infiltrating managed service providers (MSPs), cloud platforms, and government networks worldwide, putting millions of businesses and institutions at risk.
Microsoft’s Threat Intelligence team has warned that Silk Typhoon (formerly Hafnium) is now leveraging stolen credentials, remote management tools, and cloud applications to gain initial access to corporate networks. The attacks are rapidly scaling, compromising healthcare, defense, energy, and government agencies worldwide.
A cybersecurity analyst James Holloway warned:
This is a calculated, well-funded operation. IT providers are now the backdoor for espionage.
The group has also been abusing API keys and privilege access management (PAM) systems, enabling deep infiltration into cloud environments and exfiltration of OneDrive, SharePoint, and corporate email data.
Hackers have been seen deploying web shells and leveraging vulnerabilities in major platforms, including:
🔹 Microsoft Exchange (ProxyLogon)
🔹 Palo Alto firewalls (CVE-2024-3400)
🔹 Citrix NetScaler (CVE-2023-3519)
By disguising their activity through compromised routers and VPN appliances, Silk Typhoon is evading detection, making it one of the most elusive cyber threats today.
