I dispute the idea that any senior developer could work at Goldman Sachs on an HFT infrastructure and believe that they were authorized to --- or, indeed, that they would not be immeditely fired for --- uploading the code to a proprietary automated trading system to a random SVN host in a different country. This is the code we, as security testers, were never allowed to see, even after owning up the machines hosting it. These firms are not kidding around about this stuff. It is a huge smoking gun to have uploaded any of it to some off-brand foreign svn host.
These are firms where you can be fired for plugging a thumb drive into your computer, or for using the company network to access Dropbox. I have worked for more than one financial firm that spent literally millions of dollars merely on the problem of detecting their network users trying to reach Google Mail.
I also dispute the idea that because developers commonly use ssh, gzip, and svn, that it is common practice to (1) gzip a tarball of source code, (2) encrypt that source code, (3) commit that compressed encrypted blob to svn, (4) remove all traces of the encryption key from their work computer. That's something happens zero times on normal dev machines.
The conviction was overturned because the technical details of exactly what Aleynikov took from GS didn't fit the ambitious charge the DOJ filed against him. But the appeal doesn't refute the finding of facts from the original trial, which include:
There was more than sufficient evidence presented at trial, however, for a rational juror to conclude that Aleynikov intended to steal Goldman Sachs' proprietary source code. First, it was undisputed at trial that Aleynikov actually did take proprietary source code from Goldman Sachs. As Aleynikov concedes in his motion papers, the code he took from Goldman Sachs included a “purposefully designed” portion of the Goldman Sachs “proprietary, custom-built trading system.” Indeed, the evidence showed that Aleynikov took a significant percentage of the proprietary source code for that system. While Aleynikov attempted to show that there was open source code embedded within the proprietary code and to identify the files in which that might be true, his expert witness was only able to identify one file among those taken by Aleynikov that both bore a Goldman Sachs copyright banner and appeared to contain open source code.
I'm just fine with Aleynikov's conviction being overturned. Again, the charges against him seemed ambitious.
But this is a forum full of software developers. Rayiner is a lawyer and a compiler developer. It's somewhat insulting to everyone's intelligence to pretend that people here are unfamiliar with ssh and svn. We understand how software development works. What happened here was extremely sketchy. You can't play the "well in the world of software development, this is totally normal" card on HN.
