October 2^nd, 2003 (12:00am) - Early this morning the internet was abuzz with rumors that the source code for Valve’s upcoming and highly anticipated sequel Half Life 2 may have been leaked and distributed over a torrent network. Shorty thereafter, Gabe Newell of Valve Software posted a thread on the forums at www.halflife2.net in which he acknowledged the rumor as true and asked the Half Life 2 community to come together to help Valve in finding how this leak might have happened and who was involved.

Here are the contents of that post:

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.

Gordon is not amused.

It is unknown at this point in time what impact this leak will have on the release schedule of Half Life 2 (which has already been postponed to "Holiday 2003"). Stay tuned for more information as it develops.
