    Abstract: The present invention relates to a system and method for detecting a malicious file which is infected by a malicious code of a cross platform type when a user uploads one's own file on a cloud server and uses a related service by connecting with one's own account through various devices. The system for detecting the malicious file for a cloud storage according to the present invention includes an event monitoring module to transmit a suspicious file to the outside by sensing a mobile application installation event and the file modulation content of an external memory and a malicious file detecting module which determines the malicious file by analyzing a source code of the suspicious file received from the event monitoring module. [Reference numerals] (10) Event monitoring module; (11) Event detecting module; (12) File modulation detecting module; (13) Malicious file deleting module; (20) Malicious file detecting module; (21) Suspicious file receiving module; (22) Static file analyzing module; (30) Signature DB; (40) Signature scanning module
