RE: Defeating Citibank Virtual Keyboard protection using screenshot method

Without getting into SMTP latency comparisons...

Perhaps I missed something, but where is the threat demonstrated sans
code installation?
I'm not trying to disparage anyone's work, but as you yourself pointed
out, there is nothing demonstrated here that doesn't qualify as common
malware.

Granted, it's an interesting methodology, but until you can
demonstrate
circumvention of the CitiBank keylogger without installing code on the
victim host, a threat is not indicated and cannot be taken seriously.

Even though I was the first to point out this is old news for the
malware
scene in online/e fraud, I'd be the first to bow down before Int3 and
say
"thank you for sharing your work with us". Many don't.

But your point above:
"without installing malware on the victim host"

Although true on some level, is bogus for the purpose of this work, as
it
being written makes an automatic assumtion on working only after malware
is installed.

Although you are right, in practice this is already an heavily abused
technology, and.. 
'Getting malware on a system', who ever heard of such a ridiculous
idea? :)

This is not malware, it will only help people to experiment and see
the
result without writing one for themself.

      Step by Step Demo:
      
      - Download POC from http://tracingbug.com/downloads/citihook.zip
<http://tracingbug.com/downloads/citihook.zip>  and
      unzip to some directory
      - Launch citihook.exe, this will watch only
      https://www.online.citibank.co.in/ URL
      
      Effectively, "Let me install my malware on your machine to
demonstrate
      how vulnerable it is."
      
      P-p-p-p-p-p-leeeze (three anti-social points for that quote)!
      The "problem" ceases to be a vulnerability at this point.
