This warning is for HRW and any HRW vendors:
I don't know how much publicity this has gotten outside of tech circles, but there is a very significant bug that was announced Monday. The bug affects about 2/3 of all websites worldwide. It's a vulnerability in OpenSSL, and allows a hacker to obtain encryption keys, passwords, etc -- essentially the keys to the kingdom.
Any website that is taking credit card information has a 2/3 probability that they are using OpenSSL, and need to patch their site immediately, then reissue all new security certificates.
As it stands, any unpatched site is subject to man-in-the-middle attacks, and a hacker can intercept any traffic flowing in and out of the site, and easily decrypt it. Because it was announced publicly on Monday, it's open season for any would-be hackers to find and exploit unpatched websites, especially ones that are involved in financial transactions.
If the site is behind a firewall, the firewall is also subject to this attack, and will need its firmware patched.
