Fake Next.js job interview tests backdoor developer’s devices

A coordinated campaign targeting software developers with job-themed lures is using malicious repositories posing as legitimate Next.js projects and technical assessment materials, including recruiting coding tests. The attacker’s goal is to achieve remote code execution (RCE) on developer machines, exfiltrate sensitive data, and introduce additional payloads on compromised systems. Multiple execution triggers Next.js is a popular […]

Critical React2Shell flaw actively exploited in China-linked attacks

Multiple China-linked threat actors began exploiting the React2Shell vulnerability (CVE-2025-55182) affecting React and Next.js just hours after the max-severity issue was disclosed. React2Shell is an insecure deserialization vulnerability in the React Server Components (RSC) ‘Flight’ protocol. Exploiting it does not require authentication and allows remote execution of JavaScript code in the server’s context. For the Next.js framework, […]
