In fact, the priority for malware developers is not in developing more effective ways of stealing data but in creating better obfuscation for their malware in order to prevent detection from legitimate security programs. As backdoor Trojans are added to virus databases, criminals try to find new ways to use old Trojans to continue carrying out attacks rather than updating these malware infections to carry out new types of attacks.
