The redacted names are kind of pointless, because they're not redacted in the images of the emails.

I redacted their names from the post and PDF only, to prevent Google from indexing and associating the blog post with them.

By doing this, future employers hopefully will not see the blog post when searching their names.

A bounty program is to get 'white hat' hackers to find and report vulnerabilities. The bounty is small, nowhere near what an extortionist could charge to keep the source secret for instance.

By paying nothing for what could have been sold back to them for a huge sum, they may disaffect hackers, who could do them real harm. You become a sucker to volunteer for their 'bounty', and decide to turn to the dark side instead.

I think Prezi are very silly to be splitting hairs about this. They stuck the stick in the hornets' nest, now they are arguing with the hornets.

Why even have a limited scope on bounty programs? (This is not the only time I've seen that.) Is it only to limit payout? Are their legal reasons? For example, their client tablet applications are ineligible. I just don't get the reasoning. In their position, I'd pay him the $500 and remove the idea of scope. I'm just curious if there's some counter-argument I'm not thinking about.

I can see why they would want to set up rules instead of allowing anything to happen.

For example, if I was to set up a bounty I really wouldn't want people at random contacting current or former clients trying to phish for passwords; I completely understand this is a threat, but I would want to personally manage something like that.

With that said, if something like this was found I'd pay the person. There's a point where you just recognize "Oh shit, that's a big hole, pay the man.".

This sends a worrying message to others - in future don't bother reporting vulnerabilities to Prezi, just obtain the source and sell exploits to the highest bidder.

It's no wonder security researchers turn to black hat methods, when they're treated/compensated like shit for their effort. "Swag" in return for your source code? What a joke

Well of course there have to be rules. Does spear phishing employees email accounts and using their password to access control panels count as a bug? I bet I could hack a lot of companies that way. Does being susceptible to a massive DDoS count as a bug? Cutting power to the building? I can't speak for Prezi, but it seems like they want people to test the security of their app, but not of their employees or back offi…

Large tech companies routinely run pentest exercises against themselves that involve phishing their own employees. Good security has to include educating the human element as well: if you have great technical security but all you have to do to get in is ask an employee their password, you've lost.

Large companies also invest significantly in protection against massive DDoS and power cuts to the building, along with drills for earthquakes and zombie apocalypses.

Oh I see, that makes sense.

Nexus isn't a source code repository. What you found was their internal artifact server, i.e compiled jar files.

Assuming they are building in Java, it's pretty common to publish source JARs to the repository along with the compiled classes.

I don't know of enough places that use Nexus to say whether it is common practice or not, however we do not bundle jar files with sources at my place of employment where we do use Nexus. If we wanted to bundle sources into jar that would have to be done so explicitly, as it would require something like mavens source plugin. In fact in maven the standard seems to be to include sources in a separate jar, if one wants to publish the sources i.e. again requiring explicit choice and configuration.
