[GPSCC-chat] Heartbleed is real. Do something real.

Thanks for the web update Spencer. I double checked my Direct Express
online account and it is possible to send money to another bank account
after logging in, but there is also what is called "two factor security"
involved. It seems that I have to enter the code on the back of my debit
card before I can transfer money and even then the transaction might be
declined by Comerica Bank. I'm working with the account issuer to disable
online access and have them send me a paper bill in the mail with all of my
transactions for the month listed instead of having online access, but it
is not clear how much trouble it will be to do this since the customer
service rep said they weren't sure if it was possible to do this for an
active online account. She had the tech support people arrange to call me
back sometime next week. She also said that it was not possible to only
disable the online funds transfer feature and online bill pay. Two factor
security is better than just having a password and login required before
you can send money from an online bank account. If your bank doesn't have
at least that level of security, they are fools and you should switch banks
or at least disable online access for your account. Hopefully my security
code is secure on the Direct Express web site as I've never entered that
code when using that site. I'm still going to disable online access
entirely ASAP if I am allowed to do that.
On a related note, I did a search to find out if the Heartbleed bug affects
security for credit card numbers and PINs, not just passwords, and found at
least one article that confirms that it DOES affect other data such as CC
numbers. That article is located here:
http://www.christianpost.com/news/heart-bleed-virus-update-open-ssl-computer-bug-how-to-protect-your-security-passwords-for-gmail-yahoo-facebook-117732/
I also did a search to try to find out if the Heartbleed patch is available
for Windows XP. I found a bunch of articles that talked about the end of XP
security support on April 8, 2014 and that talked about the Heartbleed bug,
but none of the articles raised any alarms for XP users trying to patch the
Heartbleed bug.
