CrashMe

CrashMe is a series of trojan horses developed for the Nintendo DS. Its main purpose was to attack pirates, as it will flood the Nintendo DS firmware with junk data, rendering it unusable.

Origin

The origin of these trojans started back in 2005 with the PlayStation Portable, known as a trojan simply known as Trojan.PSPBrick. The trojan was hidden as a "version downgrader", as it would delete critical files that would restart the PSP, and replace those files with the following messages:

Your 2.0 is hacked please reboot
Thank you PSP Team the french team
FuCk yoshihiro and SonyxTeam Looser

PSP TEAM 2.0 Exploit Hack the 2.0 firmware
Thank's to toc2rta for the 2.0 exploit

A bricked PSP. You can still boot it up, but that's about it.

Trying to open any application after that would simply freeze the unit, with little to no recovery being possible. This trojan is what inspired DarkFader, to create a version for the Nintendo DS, with similarities shown.

Trojan.DSBrick.B (taihen.zip)

On October 8th 2005, just a few days from the discovery of Trojan.PSPBrick, DarkFader privately released a trojan for the Nintendo DS on IRC, which later made its way onto people's DS'es. The trojan came in an archive known as taihen.zip. The only contents were taihen.nds and taihen.txt with some text.

Enjoy!

The program was disguised as a hentai viewer which would show 5 images of uncensored hentai. But before these images, the following things will happen without the user knowing:

• The first 64kb of the DS's firmware is overwritten by junk data, preventing the unit from starting up.
• The first sectors of a inserted GBA Movie Player gets erased, but can be recovered.
• The firmware for both the SuperCard and the XG/Neo get erased. This cannot be recovered.

Plus, a 2nd (and even more) obscure version was uploaded named "DS Owata", showing 5 different hentai images, and with some altered text, with the rom pretending to be Dragon Quest IX. After the erasing job is done, some text and hentai will be displayed on the screen:

Hentai... Disgusting, am I right?

"Owata" means "finished" in English, meaning that your DS has been "finished" off.

Some of the text is also different in DS Taihen and DS Owata:

Taihen:

DS taihen v1.0

and relax :)
Wait several seconds to
see the next picture.

Owata:

DS owata :)

When the user would turn the DS off and back on again, they will be greeted with a black screen.

Trojan.DSBrick.A (r0mloader.zip)

A day later, a more wildspread and more approperiate version was uploaded on multible IRC channels and a forum as well, named r0mloader.zip. The trojan pretended it was a tool that would "automatically patch your .nds roms uppon launch", but its functionality was the same as DS Taihen.

It's just a brick wall, nothing else to see.

r0m loader for Nintendo DS
It automatically patches the game during load.
You can switch DS card / GBA cart save and save settings per game.
Put the loader on a CF or SD card together with the NDS files.
Start the loader and select the NDS to play!
Enjoy.

Currently supports:
* Supercard
* GBA Movie player

Future support:
* G6
* M3

After the erasing job is done, an image of a brick wall is shown on the top screen, with no activity. Because this version of CrashMe was more wildspread, the news was covered on multible websites and forums, being mostly virus-alert sites, with a warning for people telling them to keep an eye out and to always get roms from trusted sources.

CrashMe (2011)

Another trojan popped up around 2011, found by a GBAtemp user known as osm70, and that he found it on a regular warez site, pretending to be Mario Party DS. The file size is 58,5MB.
