Comparitech recorded 997 known and suspected ransomware attacks during August, averaging more than 32 incidents per day. The United States accounted for nearly 42 percent of the total. Ransomware activity reached a record high in August 2026, with cybersecurity researchers tracking 997 attacks worldwide during the month, according to new research from Comparitech. The total represents an average of more than 32 ransomware attacks per day. Researchers independently confirmed 7

Anthropic researchers have found a new problem hiding inside the rush toward autonomous AI: agents that behave acceptably on their own can become aggressive when other agents stand in the way. In new research on multiagent systems, Anthropic tested how Claude-based agents behave when operating in shared environments, including software projects where multiple agents depend on one another. The company argues that as AI agents spread across codebases, markets, and enterprise sy

Hackers suspected of links to China used publicly available AI tools to automate a cyberattack against Taiwanese government systems, compromising at least 85 accounts and stealing more than 2,500 personnel records, according to researchers cited by the Financial Times. The four-day campaign, which took place in early July, represents what Israeli cybersecurity company Dream described as the first observed end-to-end autonomous cyberattack against a government target. Rather t

A newly disclosed Windows zero-day is raising fresh questions about Microsoft Defender after Cyderes researchers found that the exploit can bypass a security fix Microsoft released just last month. Dubbed ShieldBreak, the vulnerability allows a standard Windows user to escalate privileges to NT AUTHORITY\SYSTEM, effectively gaining the highest level of local access without exploiting the Windows kernel, corrupting memory, or requiring administrator rights. Cyderes researchers

As artificial intelligence reshapes cybersecurity, security teams are confronting a new challenge: moving at machine speed without sacrificing accuracy, visibility, or control. In this interview, Nick Lantuh, President of Interpres Group within CyberProof, discusses how AI is changing the threat landscape, security operations, and enterprise risk. He also explains why strong data foundations, agent governance, and proactive exposure management will be critical as both attacke

This guest article was authored by Rachel Vrabec, CEO of Kanary Every CISO can tell you where their network ends. Far fewer can tell you where their organization's human attack surface begins. That gap is exactly where adversaries are operating. The most sophisticated attack campaigns targeting enterprises today don't start with a vulnerability scan or a zero-day exploit. They start with a LinkedIn search. They continue with a cross-referenced Instagram account, a data broker
