Detects a process performing a file access check for 'sbiedll.dll' (indicative of a Sandboxie presence check) followed by the immediate termination of the same process within a 2-minute window. This behavior is highly characteristic of malware attempting to detect if it is being analyzed in a sandbox environment and aborting execution accordingly.
