I really like this idea, it keeps security concerns front of mind while developing. Though in some ways I think it should be integrated as a test suite into a unit testing tool and have security flaws treated as any other bug.

I've been doing a piece of work with a client recently using a SIEM tool to monitor web and application logs for suspicious/fraudulent activity. One interesting strategy they are using is to look for
Tor exit nodes in the web logs and flag activity in these sessions as suspicious. I think this is a sensible approach, these days there is a lot more to security decisions than the binary allow/deny of a traditional firewall. The fact that it is coming from a Tor exit node does not automatically make it malicious (there are plenty of legitimate uses for Tor) however it is one part of the toolkit that someone with nefarious intent may use to hide their true identity when attempting to breach your systems. This uncertainty means that the traffic from these addresses isn't an appropriate candidate for blacklisting but rather warrants further investigation. There is a wealth of data like this available, much of it freely available, that is useful to correlate with your own data in order to build a picture of the traffic which is reaching your network. For Example:
...
I suppose the drawback to this approach is that it is still a little reactive and requires human intervention to investigate which may or may not be a problem depending on volumes. One possible enhancement is to use this data as part of the decision making process (possibly with a low weighting) in a preventative mechanism that utilises a scoring mechanism to decide if traffic is malicious such as a WAF or IPS, though I'm sure this is already implemented to some extent.

So since I heard about the leak of the LinkedIn passwords, I've been waiting to see what the first analysis of the dumped hashes would reveal. Theoretically LinkedIn is a bit of a different beast to other sites that have been breached, as the target users are working professionals, the type of people who have more than likely been educated again and again on passwords by their employers.
And
here are some results from Qualys, where they pretty quickly obtained 2 million passwords with not a great deal of effort, including gems such as 'm0c.nideknil.' Overall something like 98% of the hashes have now been cracked.
As for LinkedIn, using unsalted hashes to store passwords? This is security 101 stuff and quite frankly, embarrassing for a company of their size and age. Of course the unsalted part may not be the worst, the big question still remains about how the passwords got stolen in the first place.
As Richard previously posted - change your password! And if you are interested in seeing if your password was included* in the released ones:

(*not specifically YOUR password, but a hash of the same password as the one you were using.)

Time to change your LinkedIn password people... (and any other sites that share that password ;-) )

This arrived in my inbox yesterday:
Atari recently learned of a potential security violation in connection with the unauthorized access to Cryptic Studios’ user databases that occurred in December 2010. At that time, Atari owned Cryptic and the intrusion may have affected users on Atari’s databases as well and, therefore, we are taking proactive measures to correct the issue. This includes notifying certain users who are registered on Atari.com and TDU2.com (Test Drive Unlimited 2).
As a precaution, on Atari.com and TDU2.com, we have reset all accounts for users which we believe were affected. This will require you to reset your password upon attempting to log into each site separately to regain access to your account. To do so, please refer to our website at http://atari.com/pages/cryptic-studios-security-notice-atari-websites for detailed instructions and more information about this issue.
If the existing user name and password was used to access other online accounts, we highly recommend that you update those passwords as well.
We take the security of our user accounts very seriously and are investigating this issue further with Cryptic Studios. Please note that this was not an intrusion on our existing database, but one that occurred prior to our divestment of Cryptic Studios in July of 2011. Cryptic no longer manages Atari’s databases. Our deepest apologies for the inconvenience.

December 2010? And it took until April 2012 to tell impacted customers? *sigh*.
Look at what else occurred between the breach and the notification:
- "Arab Spring" uprisings oust leaders in Tunisia, Egypt, Yemen and Libya,
- Southern Sudan became an independent republic.
- The earthquake/tsunami and reactor meltdown in Fukushima, Japan
- British Royal Wedding
- Osama Bin Laden killed by US special forces
- End of the US Space shuttle program
- European economic crisis
- Severe flooding in Thailand and Fiji
- The entire 'occupy' movement
- Encyclopaedia Britannica stops hard-copy publication
- Steve Jobs, Elizabeth Taylor, Peter Falk, Whitney Houston, the King of Tonga and Randy "Macho Man" Savage all died.
Not good enough Atari. On the bright side, despite once owning the home console market, you're less of a household name than Sony so probably won't get as much press....
