Just in case you all haven't seen it (From HardOCP):
Half Life 2 Source Code Leaked:
We have already heard the rumors running around the net about the Half Life 2 source code being leaked, no need to keep sending the different links to websites hosting the information. We have seen the different website that are listing the files, directory tree and posting screenshots of proof but we choose NOT to post that kind of stuff for several reasons.
There hasnt been any official word from Valve yet, but when there is we will certainly bring you their statements on the issue. No matter how you slice it, stuff like this is extremely bad for the game industry. If the source code has in fact been leaked then the cheaters are well under way to creating cheats and hacks and I dont know when that has ever been a good thing or "cool". The bottom line is this, the information is out there if you are looking for it but personally, I wont be posting any of the links to people hosting this stuff. Hopefully this all turns out to be a hoax. Thanks to unscrupulous scumbags that leak this kind of stuff, we can all be sure that the wait for Half Life 2 will be much longer.
Valves Official Statement:
It seems like the rumors were in fact true and there was a lot more happening behind the scenes on this one that previously thought. This isn't just a simple matter of a leaked source code CD or your basic hacking, this was some pretty serious stuff going on here. Valve is reaching out to you guys for some help in this matter. Here is a copy of Gabe Newells Official statement:
Ever have one of those weeks? This has just not been the best couple of days for me or for Valve. Yes, the source code that has been posted is the HL-2 source code.
Here is what we know:
1) Starting around 9/11 of this year, someone other than me was accessing my email account. This has been determined by looking at traffic on our email server versus my travel schedule.
2) Shortly afterwards my machine started acting weird (right-clicking on executables would crash explorer). I was unable to find a virus or trojan on my machine, I reformatted my hard drive, and reinstalled.
3) For the next week, there appears to have been suspicious activity on my webmail account.
4) Around 9/19 someone made a copy of the HL-2 source tree.
5) At some point, keystroke recorders got installed on several machines at Valve. Our speculation is that these were done via a buffer overflow in Outlook's preview pane. This recorder is apparently a customized version of RemoteAnywhere created to infect Valve (at least it hasn't been seen anywhere else, and isn't detected by normal virus scanning tools).
6) Periodically for the last year we've been the subject of a variety of denial of service attacks targetted at our webservers and at Steam. We don't know if these are related or independent.
Well, this sucks.
What I'd appreciate is the assistance of the community in tracking this down. I have a special email address for people to send information to,
helpvalve@valvesoftware.com. If you have information about the denial of service attacks or the infiltration of our network, please send the details. There are some pretty obvious places to start with the posts and records in IRC, so if you can point us in the right direction, that would be great. We at Valve have always thought of ourselves as being part of a community, and I can't imagine a better group of people to help us take care of these problems than this community.
