U.S. Private Sector Empowered to Combat Foreign CybercriminalsU.S. Private Sector Empowered to Combat Foreign Cybercriminals
On August 12, 2026, President Donald Trump signed a memorandum instructing the National Coordination Center (NCC) to establish a program enabling vetted U.S. private sector companies to conduct cyber operations against foreign Transnational Criminal Organizations (TCOs). This initiative allows authorized firms to perform cyber surveillance and cyber effects operations, including accessing sensitive data and disrupting information systems, under federal oversight. The program aims to counter cyber-enabled crimes such as ransomware, phishing, and financial fraud targeting American citizens.
This policy marks a significant expansion of the private sector's role in offensive cyber operations, raising legal and security considerations. Existing U.S. laws prohibit private entities from conducting cyber attacks without court authorization, and this development parallels international trends, such as Germany's recent legislation granting its intelligence agencies broader cyber capabilities.

Exploiting Chrome DevTools Protocol: A New Vector for Session Hijacking in Windows Browsers
In August 2026, cybersecurity researchers disclosed a post-exploitation technique that leverages the Chrome DevTools Protocol (CDP) within active Google Chrome or Microsoft Edge processes on Windows systems. This method allows attackers with existing code execution capabilities to access cookies, saved data, and authenticated browser sessions without exploiting any specific browser vulnerabilities. The technique involves injecting code into running browser processes to activate the CDP, thereby exposing the browser's current context over a specified port. This approach builds upon prior research and tools, such as the CDP-Enable-BOF developed by SpecterOps, which facilitates the activation of the debugging server from within an existing browser process. The method requires a running browser process and is limited to x64 systems.
The significance of this technique lies in its ability to bypass traditional security measures by operating within the authenticated context of the browser. This development underscores the evolving nature of post-exploitation strategies and highlights the need for robust detection mechanisms to identify unauthorized process injections and anomalous activities within browser processes.
