- Today SKFU
has shared a bug he found in PS3 Firmware 2.8 (although he said it should be present since 2.0 through 3.0) that allows you to dump random data from the PlayStation 3 HDD and RAM.
To quote: There's a little "bug" in the PlayStation3's NAT test which causes that you can dump random data from the HDD and RAM. Why exactly this appears; I don't know, yet. But well, it is interesting.
The way how to do it is pretty simple. Set up Wireshark
on the PC and activate ICS (Internet Connection Sharing).
Connect the PS3 with the PC via LAN and start Wireshark's logging/sniffing feature on the LAN device. Now go to Settings on the PS3 and start a Internet Connection Test in the Network option.
When the PS3 starts the NAT testing it will send default STUN packets together with several IP Fragments. Those both packet types will contain random data which the PS3 grabs from the HDD and/or RAM. There you go.
