TAG-150, a MaaS operator active since March 2025, uses CastleLoader and CastleRAT in multi-stage attacks. CastleLoader acts as a loader that retrieves and executes additional malware through deceptive domains and malicious GitHub repositories, while CastleRAT functions as a remote access trojan providing attackers with system control, command execution, and data theft capabilities. Darktrace detected and blocked early attack activity, leveraging Autonomous Response to prevent further compromise and protect enterprise networks.

The Government has introduced the UK’s Cyber Security and Resilience Bill (CSRB) to Parliament, which modernises the framework for Critical National Infrastructure first established under the 2018 NIS Regulations. The CSRB broadens the scope of regulated organisations, introduces a faster two-stage incident reporting model, strengthens oversight of supply chain risk and gives the UK government greater agility to make updates through secondary legislation as technology and threats evolve.

Xillen Stealer v4/v5 introduces advanced features to evade AI detection, steal credentials, cryptocurrency, and sensitive data across browsers, password managers, and cloud environments. With polymorphic engines, container persistence, and behavioral mimicking, this Python-based malware highlights evolving threats and future AI integration in cybercrime campaigns.

A forward-looking breakdown of why modern OT environments can’t rely on visibility alone, and how combining Zero Trust access control with AI-driven behavioral detection gives industrial organizations real-time oversight, accountability, and secure remote access without disrupting operations.

Generative AI services like Amazon Bedrock are introducing new risks around access, visibility, and data exposure. This blog explores how Darktrace / CLOUD helps prevent these incidents through deep configuration visibility, privilege analysis, misconfiguration detection, and behavioral anomaly monitoring across Bedrock and SageMaker environments.

Earlier this year, Darktrace investigated the Vo1d malware campaign, tracing its activity from DGA-based DNS beaconing to major cloud infrastructure and ultimately to its C2 server communications.

Darktrace delivers the next evolution of NDR, extending an industry-first bridge across the network and endpoint gap with Self-Learning AI.

Salt Typhoon, a China-linked cyber espionage group, has been observed targeting global infrastructure using stealthy techniques such as DLL sideloading and zero-day exploits. Darktrace recently identified early-stage intrusion activity consistent with Salt Typhoon’s tactics, reinforcing the importance of anomaly-based detection over traditional signature-based methods when defending against persistent, state-sponsored threat.

This civil engineering company maintains much of the highway infrastructure across the UK. After legacy tools failed to stop advanced email threats, the company adopted Darktrace’s AI, which autonomously detected and neutralized attacks—proving its value and driving broader deployment.

Starting in July 2025, Akira ransomware attacks surged globally, targeting SonicWall SSL VPN devices. In August, Darktrace detected suspicious activity in a US network, including scanning, lateral movement, and data exfiltration. A compromised SonicWall VPN server linked the incident to the broader Akira campaign exploiting known vulnerabilities.
