AFAIR he ran windows share on public IP with no firewall (default on win95), someone got his IP from IRC? hmm <furious googling> there it is https://patpend.net/articles/zd/article2.html
"Sardu was running Windows 95 at the time. He made the mistake of leaving drive sharing on (which should not have been on by default, but for some reason, it was on). MindRape was then able to mount Sardu's hard drive (since drive sharing was enabled) with Samba. Pretty clever, right? Regardless, he did this and not only was he able to retrieve the NESticle source code, he was able to look through all of his drives. His Zip drive. His hard drive. His CD-ROM drive. Whatever he wanted. Such an invasion of privacy is ridiculous, but this is what transpired."
