When the esro owner (a chinese guy that owns a huge pserver network) got the blackrogue testserver files, lots of people started to look for vulnerabilities on the existing foreign testservers. One of them was Getzabeltz, from Spain, a really skilled person, that actually found a WebDAV vulnerability on the vSRO testserver. He downloaded the vSRO serverfiles the 15-20th of August of 2011, without certification, and asked me for a hand on making them work, since back then, there was no guides, nor any kind of support for the files. We knew the certification was missing, and I through about drew (pushedx), who made a certification server by himself for try to make the old and buggy jSRO leaked files (from back 2005, the sl.rar) to work. With the drew's help, Getzabeltz was able to make the files work. His computer wasn't powerful enough, so he gave the files to Victor, another friend, who ran the files for the tests on his computer. We planned to do the first pserver with vsro files called Phoenix, this is where this videos were recorded, back when the files wasn't public:
Then, for some reason I never understood, KingLi got the files from Victor. He started bragging about it like he was a boss, posted on elitepvpers that he got the VSRO files and that he was going to create his pserver called Dreamworld, and everyone started wondering from where the fuck he got the files. He showed obviously that the files were from VSRO, so lots of people started looking for vulnerabilities on the VSRO testserver. Many found them, chernobyl, crayu, manneke and many others got the files, and an internal spreading started, I got them too. Then, Chernobyl made his server, and due to its weird mind, he decided to release them "for the lulz". Then everything started. That's pretty much everything.
The BR files were leaked from elitesro, no one but esro owner hacked Thailand testserver, at least until some months ago. Same for the Taiwan serverfiles, the TW serverfiles that are released (but not public) are from ERoad.
