PE_EXPIRO.JX-O is a Trojan that circulates as a file infector via malevolent Java application. When PE_EXPIRO.JX-O corrupts a victimized PC, it looks for .EXE files in all folders in all available drives (removable, shared, networked), making it easy to circulate especially to other PCs that are sharing folders over a network. PE_EXPIRO.JX-O infiltrates into the affected PC as a file downloaded by other malware threats from remote websites or as a file downloaded unknowingly by computer users when visiting infected websites. PE_EXPIRO.JX-O affects files by overwriting code in the entry point and saving the overwritten code in the body of the virus. PE_EXPIRO.JX-O then adds the body of the virus to the host file. PE_EXPIRO.JX-O steals the PC's and computer 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 different command-and-control (C&C) servers.
