Malicious Packer?
I was interested in this entry Galaxy Cargo + Poker because i wanted to see if the badness of the raster routine had anything to do with PAL/NTSC timing. It turned out, that it is just very badly coded.
What puzzled me was, that the depacker was partially obfuscated by an EOR routine. I reverted that and started the program again, but for fun i also altered the chars in the SYS line to WS/G*P. Prog started and all of a sudden, my attached disk was empty, named "PREPARE TO DIE!". (I probably could have used Ians Unp64 V2.36, which gives a depacked largefile, but what i wanted was to have just an de-ofuscated original binary.) My mistake was to not examine the code any further.
This packer actually has a routine checking if the sysline was altered, and if so, the routine will format your currently inserted Disk or VOLUME to "PREPARE TO DIE!". Imagine if one had mounted a flashdrive or even an entire harddisk. Quite dangerous.
Does anybody know something about this >PWR< Packer(?) thing?
Are there any other examples of malicious C64 code like this, like screwing up your disk if things have been altered? |

Quoting chatGPZA bunch of those people who sold cracks also put timebombs into their stuff...like you can run it 100 times, then it deletes itself And today, it's the game producers themselves doing this. =) |

Not really. That'd be a disaster if anyone noticed it. |

Actually Sony has installed a rootkit on CD in the past and many if not all anti-cheating / DRM systems could be quite malicious from end-user perspective not to mention disliking being run under debugger which can be equivalent of running with AR enabled back in the 80's. |

I know - but i am not falling for the bite. "Buying" a game never meant you have the right to play it until eternity under all circumstances. |

When you buy something sold with a perpetual license, it is yours to play until the end of the universe. EULA are not legal contracts and I hope to hell someone challenges this in court because it's bullshit.
Also just avoid ubisoft and any other such company like Sony then. It's anti-consumer and shouldn't be legal. |

Until your internet goes down ;) Or they take your ability to play it away, like The Crew. |

Works offline just fine. And nothing has been "taken away", ever.
Edit: correction, the PS3 Store "closed" recently (you can no more buy games - but of course still play what you have bought). About 15 years after anyone would want to use it. |

To chime in on that: funny, i have just a few months ago ripped all my PS3 games from the console and managed to put them in RPCS3. Well surely i cannot play any online stuff, but then again: i have none of the games that require that. So. Yeah, it could be seen as kind of a malicious business model :-D |
