While transhumans still are far away from YGBMs, Basilisks and the Exsurgent virus, that doesn't stop them from trying. Here is a nice/nasty little hack one of my players whipped up (it actually saved the day later in the session):
Dān yǔ (Monolingual) 1.1
This is a piece of software that edits ego software to block all languages except mandarin Chinese, which it adds through a skillsoft-like function. The result is that the recipient can only read, speak and understand mandarin with a noticeable military style of speech - the language software was retrofitted from some military software. It is not very selective: it will replace native Mandarin with its own skillsoft and the neural patching is downright brutal - neurological side effects are common.
The software will only work on cyberbrains or ego storage files: biobrains cannot easily be edited. It has not been tested on AGIs or uplifts: *hopefully* it will detect a different brain structure and not try to edit it, but nobody has tried so far. It is not on its own able to spread, but it could be combined with intrusion tools or viral software/hardware to breach personal security. There is a removal feature that allows it to restore the edited neural network, but it is up to the launcher to determine whether it is active (default is inactive) and it can be equipped with a code lock so that it will only do it when given a properly authorized message.
Effects: If successfully run it will block all language skills (except unusually lateralized language skills, like in Japanese-readers who have either katakana/hiragana and kanji in the "wrong" hemisphere), replacing them with Mandarin Chinese 40. The experience produces 2d10 / 1d10+3 SV due to the mental intrusion and the crude hacking. Beside normal traumas neurological damage is an option.
The present version 1.1 is an improved, less damaging form of 1.0 that contains better language subsystem identification routines: 1.0 does double the stress damage to egos.
What other nasty mind viruses have you come up with?
