GrayBravo Expands CastleLoader Malware Service: What You Need to Know

In this video, we explore the recent developments surrounding GrayBravo, a threat actor leveraging the CastleLoader malware in a rapidly evolving cybercriminal landscape. On December 9, 2025, Recorded Future's Insikt Group released a comprehensive analysis detailing how four distinct threat activity clusters are utilizing CastleLoader as part of a malware-as-a-service model. This video will provide insights into the nature of these threats, their operational tactics, and the broader implications for cybersecurity. What you’ll learn: The origins and capabilities of CastleLoader and its associated threat actor, GrayBravo. A clear timeline of the various threat clusters and their methods of attack. The impact of these malware campaigns on specific industries and practical advice for organizations to mitigate risks. What to watch for in the future as these threats evolve. GrayBravo, previously known as TAG-150, has demonstrated rapid development and technical sophistication since the emergence of CastleLoader in early 2025. This malware loader facilitates the distribution of various malicious payloads, including remote access trojans and data stealers, through a multi-tiered infrastructure designed to evade detection. The analysis identifies four distinct clusters of activity: 1. *TAG-160* targets the logistics sector through phishing and ClickFix techniques, active since March 2025. 2. *TAG-161* employs Booking.com-themed campaigns to distribute malware, active since June 2025. 3. A third cluster uses infrastructure mimicking Booking.com to deliver CastleRAT via CastleLoader, also active since March 2025. 4. The fourth cluster utilizes malvertising and fake software updates to distribute CastleLoader and NetSupport RAT, active since April 2025. The implications of these findings are significant, as GrayBravo's activities have expanded their user base, indicating a growing threat landscape. Organizations, particularly in the logistics sector, must remain vigilant against sophisticated phishing attempts and malware distribution tactics. Recorded Future's analysis emphasizes the importance of understanding the operational tactics of these threat actors to enhance cybersecurity measures. As we look to the future, organizations should implement robust security protocols, including employee training on recognizing phishing attempts, regular software updates, and incident response planning. Keeping an eye on emerging threats and adapting to the evolving tactics of cybercriminals will be crucial in safeguarding sensitive data.
