A System Administrator contacts you (because you're the forensic geek/god) and asks for your assistance in looking at something. He then hands you a flash device with a single zip files that he explains was "handed off" to him by another admin. The file is named "Suspicious_File" and was reported by the user as being unrecognized and not sure where it came from. Eventually the user contacted desktop support staff, who eventually forwarded it to an administrator, who has now contacted you. Unfortunately, the user changed the original name and zipped it to send to the helpdesk, so the original name or path is unknown.
Analyze the file and if possible, determine its origin, purpose, function and any other information that might be useful to the administrator. To avoid posting the correct results and spoiling it for anyone else who may be trying to work through this problem, post the final hash value of any file you analyze in the comments and I will provide feedback from there.
