The Hidden Danger of Memory-Only Malware

Memory-only malware, often referred to as fileless malware, is a sophisticated cyber threat that resides entirely in a system’s RAM. Unlike traditional malware, it leaves no files behind, making detection extremely difficult. It exploits system vulnerabilities and injects malicious code into legitimate processes, allowing it to operate undetected and disappear after a reboot. This stealthy behavior enables attackers to bypass antivirus defenses and launch data breaches or surveillance unnoticed. To counter such threats, businesses must implement advanced security measures like real-time monitoring, behavioral analytics, and robust endpoint protection to identify and stop these invisible intrusions before they cause damage.

Shocking Rise: ResolverRAT Attacking Healthcare and Pharmaceutical Via Sophisticated Phishing Attacks

Ravi Jain
The source describes ResolverRAT, a sophisticated new remote access trojan identified in 2025 that primarily targets the healthcare and pharmaceutical industries. This malware is particularly dangerous because it executes solely in memory, employs advanced encryption, and utilizes unique loader architecture to evade detection by traditional security measures. ResolverRAT is disseminated through highly tailored, region-specific phishing emails containing fear-inducing narratives to trick recipients into downloading disguised executable files. The impact on healthcare is severe, potentially leading to data breaches, financial losses, and reputational damage due to the sensitive nature of patient data and research. The text suggests that combating this threat requires a multi-layered cybersecurity approach, including advanced monitoring, threat hunting, employee training, and robust endpoint detection and response tools. ...
