Online finance flaw: Ameriprise III - please make it stop

Image
NOTE: This issue was disclosed responsibly and repaired accordingly.

"Now what?", you're probably saying. Ameriprise again? Yep.
I really wasn't trying this time. Really.
There I was, just sitting in the man cave, happily writing an article on version control and regression testing.
As the Ameriprise cross-site scripting (XSS) vulnerabilities from August 2009 and January 2010 were in scope for the article topic, due diligence required me to go back and make sure the issue hadn't re-resurfaced. ;-)
I accidentally submitted the JavaScript test payload to the wrong parameter.
What do you think happened next?
Nothing good.
I reduced the test string down to a single tic to validate the simplicity of the shortcoming; same result.

An example, for your consideration: messenger-download.info
After a little exploration it was quickly determined that these cretins seek only to con victims out of credit card data with the promise of illegal downloads for a fee.
Apparently these dbags have been at it for awhile.
They make it look like you're going to receive access to a legitimate offering then they suck you in to freedownloadzone.com.
This, of course, pissed me off, so...off to the races.
A poke here, a tickle ther…

toolsmith: Firefox Addons for the Security-minded

Image
Few websites are safe from a hearty probe when I come by for a visit, and I'd be remiss if I didn't share some of my favorite Firefox add-ons utilized as part of said probing.
I opted to do just this as the topic for February's toolsmith, and focused on the expected standards (NoScript, FoxyProxy Standard, BetterPrivacy, and Torbutton) as well as some of my less known favorites.
