Disclosed herein are systems and method for blocking malicious script execution. In one exemplary aspect, the method includes determining, on a first computing device of a plurality of computing devices, that a first script on the first computing device is malicious. The method includes identifying a plurality of operations in an execution flow of the first script and generating a first hash value of attributes associated with the plurality of operations in the execution flow, wherein the attributes omit a name of the first script and a location of the first script on the first computing device. The method includes generating a first rule that prevents execution of any script whose generated hash value would match the first hash value of the first script and transmitting the first rule to a second computing device that subsequently blocks scripts based on the first rule.

Systems and methods for blocking malicious script execution based on generalized rules

Disclosed herein are systems and method for blocking malicious script execution. In one exemplary aspect, the method may comprise detecting an execution of a script that creates or modifies a file on a computing device and recording a first report comprising a list of operations involved in the execution of the script, an identifier of the script, and an identifier of the file. The method may comprise determining that the file includes malicious code using a malware scanner and recording a second report comprising an indication that the file includes malicious code and an identifier of the file. In response to determining that identifier of the file is present in both the first report and the second report, the method may comprise generating and storing a first rule that prevents complete execution of any script that shares at least one operation in the list of operations with the script.
