No Files, No Trace? Think Again: Detecting Fileless Execution Attacks in the Cloud

Stream's Engineering Desk discusses the challenges and solutions related to fileless execution attacks, which bypass traditional security measures by executing directly in memory without leaving a disk footprint. These attacks are particularly stealthy and can evade detection from traditional tools like anti-virus and endpoint protection systems, as they rely on legitimate tools already present in the operating system. Stream.Security addresses these challenges using extended Berkeley Packet Filter (eBPF) technology to monitor system activities at the kernel level, capturing detailed event summaries in real time whenever fileless execution occurs. Their CloudTwin™ technology further enhances detection by analyzing behavioral patterns and identity correlations across cloud environments, allowing for immediate flagging of suspicious activities without relying on static malware signatures. This approach provides security teams with enriched forensic details and prioritization for rapid response, effectively closing the detection gaps left by traditional methods.
