Executive Summary
In 2025, Red Canary analyzed over 110,000 threats across more than 4.5 million identities, endpoints, and cloud assets, revealing significant shifts in the cyber threat landscape. Key findings include a surge in identity-related attacks, with adversaries targeting credentials through info stealers, consent phishing, and OAuth abuse. Browsers have become primary attack vectors, serving as both the main workspace for users and a conduit for malicious payloads via compromised extensions and token theft. Additionally, the abuse of Remote Monitoring and Management (RMM) tools has escalated, with adversaries leveraging these tools for unauthorized access and control. (redcanary.com)
These trends underscore the evolving tactics of cyber adversaries and the necessity for organizations to implement layered security controls. The interconnected nature of identity compromise, browser exploitation, and social engineering highlights the importance of comprehensive defense strategies combining device trust, user authentication, and behavioral monitoring to mitigate these emerging threats.

Why This Matters Now
The 2026 Threat Detection Report highlights a significant evolution in cyber threats, emphasizing the urgent need for organizations to adapt their security strategies. The rise in identity-based attacks, browser exploitation, and RMM tool abuse demonstrates that traditional defenses are increasingly insufficient. Implementing comprehensive, layered security measures is critical to protect against these sophisticated and interconnected threats. (redcanary.com)
Attack Path Analysis
Adversaries initiated the attack by compromising user identities through consent phishing and infostealers, gaining unauthorized access to cloud accounts. They escalated privileges by exploiting OAuth tokens and manipulating IAM roles to expand their access. Utilizing compromised credentials, they moved laterally across cloud services and regions, accessing sensitive data and critical systems. Established command and control channels were maintained via remote monitoring and management tools, enabling persistent access. Sensitive data was exfiltrated by copying it to external cloud storage and leveraging covert channels. The attack culminated in significant impact, including data destruction and business disruption.
