The backdoor penetration is carried out using a malicious JTD file that backpacks aTrojan Dropper named  Ichitaro.Tarodrop.aÂ'. The Trojan Dropper exploits a UnicodeStack Overflow Vulnerability in the text editing software to execute its code on thesystem and to extract a backdoor named  Win32.Papi.aÂ'.
Once activated, Win32.Papi.a installs itself in the system registry, initiates aService named CAPAPI, drops its main DLL file which is then injected into therunning processes of the compromised computer. It establishes a connection with theremote Server on port 8080 and listens for commands from the remote attacker.
The backdoor can harvest system information, stop and start processes, takescreenshots of the desktop and send them to the attacker, download files from thenet and execute them, capture network user information, log off current user, searchdisks for files, create and move directories and restart the victimÂ's machine. UsingWin32.Papi the attacker takes over the targeted machine completely to conduct arange of online criminal activities.
 ItÂ's not the first time text editors are used in smuggling malware into usercomputers. In May, we had reported about  Win32.GusiÂ' that was spread via aspecially created Word file that exploited a security flaw in Microsoft Word, whichincidentally was reported the first time in Japan with the attacker possibly sittingin China, says Sunil Kripalani, Vice President, Global Sales and Marketing,MicroWorld Technologies.

The CEO of MicroWorld Technologies, Govind Rammurthy, gives a broader view on theissue  Trojans and Backdoors that exploit vulnerabilities in system and applicationsoftware can spread quiet fast and deliver their payload without much of userintervention. They are like camouflaged infiltrators who sneak into your homelandand expand their deadly mission under the cover of darkness. And this particularcase goes well to underline what we have been advocating all along, that users needto update timely security patches not just for their Operating Systems, but forapplication software programs as well.Â
