A new kind of Trojan was discovered recently which targets Japanese file-sharers exclusively. When executed, the Trojan displays manga-like images with a text that differs depending on which image is displayed.
The text however brings the same message across all the time as it asks users to stop using P2P networks. One of the messages for instance reads ""Ah, I see you are using P2P again...if you don't stop in 0.5 seconds, I'm going to kill you." Talk about a threat boy, jeeze."
This however is not the real danger of this Trojan. While the Trojan displays the message and plays a song, it is deleting files in the background. It targets many important file types such as exe, bat, xls, mp3 and mbx apparently.
This could mean that it deletes your mailbox, some important excel spreadsheets and other executable files, some of which may be required to run the operating system or important programs on it.
It was first suspected that a copyright holder was responsible for the creation and spreading of the Trojan but I think this theory is highly unlikely. I'm not familiar with Japanese laws but I don't think it would hold up in court if it came to light that a rights holder used a trojan to delete files on user computer systems, especially if it may not be clear at all times if copyrighted materials were downloaded to the system.
The trojan seems to be clearly targeted at certain user groups which is a fair assumption if you consider the looks and feels of it.
The manga nature of the trojan does not necessarily mean that it is targeting children, as manga is an all-ages favorite in Japan, and not exclusive to children.
Users should be aware that it is always dangerous to run unknown programs even with an up to date firewall and antivirus solution. It is always better to stop the urge to run a program and be on the safe side, than to run it and face consequences like deleted files. source: zeropaidAdvertisement
