Bank of America -FAIL
Websites used for email, banking, e-commerce and other sensitive applications just got even less secure with the release of a new tool that siphons users' authentication credentials - even when they're sent through supposedly secure channels. Dubbed CookieMonster, the toolkit is used in a variety of man-in-the-middle scenarios …
Next, clear all cookies marked as "SECURE" (in Firefox, go to preferences > privacy > show cookies. Delete only the cookies marked as "Encrypted connections only").
What if you visit the site and it doesnt have "marked as SECURE/Encrypted connections only" It has JSESSIONID, WT_FPC, and a couple of Apache... is that good or bad :s
This is a man in the middle attack run on a local network, you can do far more than nab cookies to sites.
And it is amusing people don't understand how cookies work, Lou Montulli is probably spinning in his grave (ok he is not dead, well not that I know off), but the mechanism has been in for ages to only transmit over a secured channel.
And you would have thought with all this phorm business, people would have looked into how they were handling their cookies, but a lot of folks use frameworks and obviuosly people who don't know what they are doing have been building those.
It is a little bit of a storm in a teacup, but the fix is so trivial, it is called not hiring cowyboy coders.
If you use an external proxy server you could easily be vulnerable to a Man in the Middle attack, but then if you're accessing sensitive sites via this method, you should step away from your PC.
Of course, there is the additional problem of the ubiquitious "transparent caches" employed by some ISPs, also.
I noticed that at least one person commenting above didn't understand the instructions properly, btw.
I see no "secure connection only" cookies after logging in to the co-op bank website, so presumably they're vulnerable.
Curiously Halifax do send one "secure only" cookie, however removing it doesn't cause the session to close so presumably it's one of the "any type of connection" cookies that actually matters.
Pathetic. Let's see how long it takes them all to fix it.
Royal bank of scotland fails for the login but now requires the use of crazy encrypto calc to do any sort of transfers outside of your own accounts.
So, someone could come in and transfer money between my own accounts, but would not be able to set up direct debits, transfer to someone else's account etc.
Not great, but at least its something. Just in time too. This is brand new,
