ResolverRAT Malware: A Growing Threat to Enterprise Security

ResolverRAT is a sophisticated remote access trojan (RAT) targeting enterprise systems to exfiltrate sensitive data and enable persistent control over compromised networks. Often delivered through phishing emails or malicious attachments, ResolverRAT can record keystrokes, steal credentials, capture screenshots, and execute commands remotely. Its stealthy behavior makes detection challenging, allowing attackers to conduct espionage or prepare for larger-scale intrusions. Cybersecurity experts warn that ResolverRAT is evolving with encrypted communication and anti-analysis techniques. Organizations must implement advanced endpoint protection, email filtering, and employee training to defend against such threats. Proactive threat hunting and regular security audits are crucial to prevent ResolverRAT infiltration.
