Half-Life 2 is now Open Source

The source code for Half-Life 2 has been posted on the net!

One of the developer writes:
Around 9/19 someone made a copy of the HL-2 source tree. 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).

Read the whole thread!

Perhaps this can learn people never to run Microsoft Outlook. Use a real mailclient where security is not just an entry in the help file. Use Mozilla Mail or Mozilla Thunderbird.

One person posted on the forums that they should not be using the 'preview pane', Mozilla's term 'Message pane' is a lot more appropriate because I don't use that pane for previewing messages, I use it exclusively for reading the messages and opening attachments.

Therefore a mailer where it's advised to disable this pane is unusable imho, because you have to double click each message to read it.

You'd hope people would learn from these incidents two things:

1) MS Outlook (and OE) have had one of the worst security track records, so are worth avoiding based just on past performance (which ain't always necessarily a guide to future performance)

2) Staff should be trained to recognise attachments and told not to run anything that they don't know is from a trusted source.

Mozilla mail also has one important advantage over Outlook it shows both the senders name and email address in the message pane, Outlook just shows the name when both are specified. OK it's possible to forge both the name and email address, but if you want a reply then you could use a valid email address (e.g. a hotmail one) and then put the name of the CEO of the company your emailing as the sender and ask someone to send you some important company sensitive information.

This actually sucks. I live in Seattle and I know a Valve developer who has put years into this game. Now their competition will get a look at all their hard work. Your average kid will not be able to make heads or tails of it but other game developers will love to read it.

Valve are good guys who make a good product.

Well, it's not the other game developers who will be taking a look, but the cheat writers.
Even worse, if the HL2 code contained the STEAM content distribution client source, not only Half-Life 2 is affected, but every current Valve game.

It's a real shame, because I also think Valve is a great company that makes great products.

Your title "Half-Life 2 is now Open Source" sounds like Valve released the source code deliberately, but in fact it's the real opposite. I think the term "Open Source" should not be connected to code theft.

the term "now Open Source" was meant as a joke....! Everybody should know that the code couldn't be open source since it represents their income for the next years.

Half Life 2 sucks your all idiots, I hope Sierra burns up. They stole parts of quake source, and used it in their game. Only months later ID released their sources to their quake titles, then sierra made the move to outsource Half Life 2 for game developers.

You talk about theft, I think Sierra got what it deserved. Half Life 2 all rave, majority of the community is made up of faithful gamers no different than World of Warcraft.

"Valve are good guys who make a good product."

...and then sell you the conclusion in $20 pieces a few months later.

I like HL2 more than other games out there right now but Valve is starting to come off as pushing just a little too hard with Steam and the never ending flow of mixed-quality buy-me-now's.

A theft is a theft, no matter how we look at it, Programming is long and tideous work that should have it's just rewards and by this I do not mean have your codes stolen! maybe someone will realize one day that when it comes to security microsoft does not have a clue, look at the difference between linux and windows for example, linux has remote access all closed if not a few open ports depending of the distro while windows has everything wide open! please learn not to trust microsoft, beside the company wants a monopoly, I think microsoft deliberately creates security issues with their software so someone can keep antivirus software company rolling, rememeber that antivirus are not free anymore
