Researchers at Check Point link ‘Amarath-Dragon’ attacks to prolific Chinese cyber-espionage operation

Cybersecurity researchers have discovered a new campaign attributed to a China-linked threat actor known as UAT-8099 that took place between late 2025 and early 2026

Chinese Attackers Among Those Tied to Attempted Exploits of FortiSIEM AppliancesCritical vulnerabilities in edge devices are continuing to be discovered by security researchers and rapidly targeted by attackers. Lately, this includes a critical vulnerability in Fortinet's FortiSIEM appliances, which Chinese and other hackers began targeting just two days post-patch.

New research from CrowdStrike has revealed that DeepSeek's artificial intelligence (AI) reasoning model DeepSeek-R1 produces more security vulnerabilities in response to prompts that contain topics deemed politically sensitive by China

Chinese Hackers Target European Diplomats with LNK File FlawChinese nation-state hackers are exploiting a Windows vulnerability to hack European diplomatic outposts, say security researchers - but operating system giant Microsoft says the flaw doesn't merit a patch. Hackers used a flaw already compromised by North Korea and Russia.

Cybersecurity researchers are calling attention to malicious activity orchestrated by a China-nexus cyber espionage group known as Murky Panda that involves abusing trusted relationships in the cloud to breach enterprise networks

145 Organizations Compromised by China-Linked Ransomware Hackers and OthersNearly 150 different organizations' on-premises SharePoint servers have been exploited by attackers targeting the zero-day vulnerabilities now tracked as ToolShell, researchers warn. Early attacks have been attributed to China-linked groups, in some cases leading to Warlock ransomware infections.

But Hacking Groups of All Stripes Now Have Access to Exploit Code, Researchers WarnMicrosoft said an attack campaign targeting zero-day vulnerabilities in on-premises SharePoint servers appears to have begun by July 7, tied to three Chinese hack groups. With proof-of-concept exploit code now in the wild, security experts said hackers of all stripes have joined the fray.

Telecoms Still Falling to Chinese Nation-State Hacking Group, Researchers WarnA Chinese cyber espionage group tracked as Salt Typhoon and tied to the mass hacking of telecommunications networks in the U.S. and dozens of other countries has been continuing to seek and hack unpatched equipment, including exploiting two long-patched vulnerabilities in Cisco gear.

Researchers uncovered flaws in large language models developed by Chinese artificial intelligence company DeepSeek, including in its flagship R1 reasoning application. The security concerns come as Microsoft and OpenAI investigate whether DeepSeek developed used data scraped from an OpenAI API.

No Patch Yet Available for Second Zero Day to Be Recently Found in VoIP SoftwareSecurity researchers warn of a newly discovered zero-day vulnerability in widely used VoIP telephony software, a discovery that comes as the United States struggles to evict Chinese nation-state hackers from telecom networks. The software is the MiCollab software suite from Canada-based Mitel.

DeepSeek-R1 Struggles with Logic Tests and Is Vulnerable to JailbreaksChinese artificial intelligence research company DeepSeek, funded by quantitative trading firms, introduced what it says is one of the first reasoning models to rival OpenAI o1. Reasoning models engage in self-fact checking and perform multi-step reasoning tasks.

Malicious hackers are exploiting a zero-day vulnerability in Versa Director, a software product used by many Internet and IT service providers. Researchers believe the activity is linked to Volt Typhoon, a Chinese cyber espionage group focused on infiltrating critical U.S. networks and laying the groundwork for the ability to disrupt communications between the United States and Asia during any future armed conflict with China.
