And so here we go with the entire rootkit fiasco all over again. Thanks Sony for showing incredible idiocy in the face of ineptitude.According to developer Mathieulh, the official PS3 firmware v3.56 is said to contain a rootkit which allow Sony to perform remote code execution upon connection to the PlayStation network. What this means is that Sony can scan for specific files on your PS3 console?such as custom firmwares and hombrew applications?and send a report back to the company. Whether this is legal or not is yet to be determined but be careful what you put on your PS3.
