February 5, 2026 · Cybereason · Severity: MEDIUM

Cybereason's Q4 2025 TTP Briefing highlights a surge in diverse phishing tactics and remote access trojans (RATs) targeting organizations globally. The report, based on frontline incident response data and SOC detections, reveals attackers are increasingly leveraging sophisticated social engineering techniques, including AI-generated phishing emails and impersonation of trusted entities. RATs like QuasarRAT and AsyncRAT remain prevalent, enabling persistent access and data exfiltration. The findings underscore evolving threats to businesses across sectors, particularly finance, healthcare, and critical infrastructure. Cybereason notes a rise in multi-stage attacks combining phishing with exploit kits (e.g., CVE-2025-XXXX vulnerabilities) to deploy malware. These trends emphasize the need for enhanced employee training, endpoint detection, and proactive threat hunting to mitigate risks. The report serves as a critical resource for defenders adapting to the rapidly changing threat landscape.
