As the war against malware continues to evolve, malware developers are increasingly using professional software development methods and continue adding in new evasion techniques to prevent their malware from being detected. Malware writers have included antivirtual machine detection in their tool chests since at least 2006 to prevent researchers from analyzing their malware and developing signatures for detection and prevention. Automated anti-malware tools also use virtual machines for analysis to block the malware. Some malware is now checking for mouse activity to prevent analysis. As an example of why such techniques could be valuable to attackers, malware could check to confirm it can reach the command-and-control infrastructure prior to activation.
Endpoint anti-malware tools do not necessarily need to detect if there is mouse activity while checking for malware, but the researchers at the anti-malware vendors need to be able to analyze the malware to develop signatures or methods to detect the malware. Once a signature or detection method is created, it can be used to prevent malware from potentially executing on the endpoint before checking for mouse activity. If the anti-malware research teams are not picking up on these threats, enterprises should be concerned because that would call the endpoint security tool into question if it can't adapt to detect new attacks. Enterprises may want to investigate alternative anti-malware products or other endpoint security tools (e.g., whitelisting) that could detect or prevent malicious code from running on an endpoint.
