Despite substantial investments in numerous security products, organizations continue to be victims of successful malware attacks and data breaches. Today’s sophisticated malware has been engineered to discover and outsmart “advanced” security tools like firewalls, IPS, and sandbox technologies. These technologies are unable to detect the wide range of evasion techniques described below. So-called “advanced” or “next-generation” sandboxes continue to rely on signatures and analyze files only at the application and operating system level, which makes it possible for malware to escape undetected.
Sandboxes use virtual machine (VM) technology to analyze suspicious objects. Although VMs resemble a real host, they also insert artifacts into the VM environment for the virtualization to work. These artifacts include additional operating system files and processes, supplementary CPU features, and other components. Sophisticated malware can detect these artifacts, alter its behavior and avoid detection.
Advanced malware avoids being detected by sandboxes or other security controls by altering its behavior and adopting one or more evasion tactics, such as:
Another advancement criminals have made is malware that doesn’t reside in a file. Dubbed fileless malware, these threats reside entirely in memory and remain hidden from most malware discovery tools. The most sophisticated versions of fileless malware also are able to completely disappear after reaching their objectives. By operating in such a way that nothing is ever written to disk, and then wiping themselves from memory when done, this ultra-evasive type of malware is extremely difficult to detect.
