Here is the technical report by SentinelOne.

An IT services company, a European media group, and a South Asian government entity are among the more than 75 companies where China-linked groups have planted malware to access strategic networks should a conflict break out.

SentinelLABS, the threat intel and research arm of security shop SentinelOne, uncovered these new clusters of malicious activity when the suspected Chinese spies tried to break into SentinelOne's own servers in October.

"We tend to prioritize China, and seeing them start to poke at our own products, our own infrastructure, that immediately raises the red flag for us," SentinelOne threat researcher Tom Hegel told The Register in a phone interview. While the attempted SentinelOne intrusion was unsuccessful, being the target of a Chinese reconnaissance campaign led the threat hunters into a deeper analysis of the broader campaign and malware used.

"We started to hunt for it globally, look at their infrastructure and identify those other victims," Hegel said.

[...]

SentinelLABS found more than 70 victims globally across manufacturing, government, finance, telecommunications, and research. One of these was an IT services and logistics company that manages hardware logistics for SentinelOne employees.

Additionally, the security outfit's research uncovered a September 2024 intrusion into a "leading European media organization."

It's a broad range of victims, but they all share one thing in common: they represent strategic targets as China prepares for war of the cyber or kinetic variety.

[...]

SentinelOne, as a security vendor for government and critical infrastructure organizations, makes an attractive starting point for a supply-chain attack along the lines of what Russian spies did to Mandiant during the SolarWinds fiasco.

Security firm Forescout identified almost 35,000 solar power devices from 42 vendors with exposed management interfaces. These devices include inverters, data loggers, monitors, gateways and other communication equipment.

Key Findings

• Despite being a rapidly growing renewable energy source, there are security issues with remote inverter management, via cloud applications or direct access to management interfaces within inverters.
• Internet-exposed solar power devices are much more popular in Europe and Asia than in other regions. Europe accounts for 76% of exposed devices, followed by 17% in Asia and the remaining 8% in the rest of the world. Germany and Greece each account for 20% of the total devices worldwide, followed by Japan and Portugal with 9% each then Italy with 6%.
• Four of the top 10 vendors with exposed devices are headquartered in Germany, two in China and one each in Austria, Japan, US and Italy. This distribution also does not match the top 10 vendors worldwide by market share, since 9 of those are Chinese.

Mitigation Recommendations

• Do not expose inverter management interfaces to the internet.
• Patch devices as soon as possible and consider retiring those that for some reason cannot be patched.
• If a device needs to be managed remotely, consider placing it behind a VPN and following CISA’s guidelines for remote access.
• Follow the NIST guidelines for the cybersecurity of smart inverters in residential and commercial installations.

Insights from contributors

CVE-2025-22252: Authentication Vulnerability in FortiOS, FortiProxy, and FortiSwitchManager leads to Unauthenticated Admin Access
CVE-2025-22252 is a missing authentication for critical function vulnerability in devices configured to use a remote TACACS+ server for authentication configured to use ASCII authentication. It may allow an attacker with knowledge of an existing admin account to access the device as a valid admin via an authentication bypass, potentially resulting in complete system compromise, data theft and service disruption.

CVE-2025-30663: Additional information
In its security release of 13 May 2025, Zoom addressed two vulnerabilities that could be exploited for privilege escalation: • CVE-2025-30663, a time-of-check time-of-use race condition affecting some Zoom Workplace Apps. If successfully exploited, an authenticated user could conduct an escalation of privilege via local access. • CVE-2025-30664 is an improper neutralization of special elements flaw affecting some Zoom Workplace Apps. Successful exploitation could allow an authenticated user to conduct an escalation of privilege via local access.

CVE-2025-41229: More information
The vulnerabilities could be used by attackers to gain access to services and data. They can also be used to execute arbitrary commands and cause a denial of service. Confidentiality, integrity and availability are all impacted. The only solution is to upgrade immediately.

2025-27920: Additional information
Microsoft discovered critical vulnerability CVE-2025-27920 affecting the messaging application Output Messenger. Microsoft additionally observed exploitation of the vulnerability since April 2024. According to Microsoft, the attacker needs to be authenticated, although the Output Messenger advisory indicates that privileges are not required to exploit the vulnerability. An attacker could upload malicious files into the server’s startup directory by exploiting this directory traversal vulnerability. This allows an attacker to gain indiscriminate access to the communications of every user, steal sensitive data and impersonate users, possibly leading to operational disruptions, unauthorized access to internal systems, and widespread credential compromise.

Continuous exploitation

• CVE-2023-0656 - SonicWall / SonicOS (not in CISA KEV)
• CVE-2022-26134 - Atlassian / Confluence Data Center
• CVE-2019-1653 - Cisco / Cisco Small Business RV Series Router Firmware
