PS2 Exploit Found

[mamajo1]

To make a long story short, the exploit allows anyone with a memory card and a valid, legal PS1 disc to hijack the boot process and run any piece of code. Absolutely no modification to the system is necessary to use the exploit (my only working PS2 is not moddded, and I have developed and tested the exploiton this machine). All one really needs is a way to send the files to thememory card to enable the exploit.

If this is true for those with modded Ps2 can we run this exploit so that when our chips are turned off, we can run backups without the Dnas detecting a modchip present? Also it would be very difficult for sony to patch an exploit unlilke the Xbox where it can be updated through Live so would there be anyway for Sony to detect this exploit while trying to connect to their servers?
