PE_EXPIRO.JX-O is a Trojan that spreads as a file infector via malicious Java applet. Once PE_EXPIRO.JX-O infects a vulnerable computer system, it searches for executable files in all folders in all available drives (removable, shared, networked), making it easy to proliferate especially to other computers that are sharing folders over a network. PE_EXPIRO.JX-O invades the targeted computer system as a file downloaded by other malware infections from remote websites or as a file downloaded unknowingly by PC users when visiting malicious websites. PE_EXPIRO.JX-O corrupts files by overwriting code in the entry point and saving the overwritten code in the virus body. PE_EXPIRO.JX-O then attaches the virus body to the host file. PE_EXPIRO.JX-O steals the computer system's and PC user's information, such as the Windows product ID, Windows version drive, volume serial number and user login credentials. PE_EXPIRO.JX-O also steals stored FTP credentials from the Filezilla FTP client. PE_EXPIRO.JX-O saves the stolen information in a .DLL file and uploads it to numerous command-and-control (C&C) servers.
