Windows file system minifilter driver5/29/2023 Our evaluation shows that UNVEIL significantly improves the state of the art, and is able to identify previously unknown evasive ransomware that was not detected by the anti-malware industry. In parallel, the approach tracks changes to the system's desk-top that indicate ransomware-like behavior. UNVEIL automatically generates an artificial user environment, and detects when ransomware interacts with user data. The key insight of the analysis is that in order to mount a successful attack, ransomware must tamper with a user's files or desktop. In this paper, we present a novel dynamic analysis system called UNVEIL that is specifically designed to detect ransomware. However, while many generic malware detection systems have been proposed, none of these systems have attempted to specifically address the ransomware detection problem. In fact, in the last few years, a number of high-profile ransomware attacks were reported, such as the large-scale attack against Sony that prompted the company to delay the release of the film "The Interview." Ransomware typically operates by locking the desktop of the victim to render the system inaccessible to the user, or by encrypting, overwriting, or deleting the user's files. Although the concept of ransomware is not new (i.e., such attacks date back at least as far as the 1980s), this type of malware has recently experienced a resurgence in popularity.
