Interesting thread here...anyone considering "mutual authentication"
(i.e. user defined server image or something similar)?

Best,
Bill

Subject: [windows-hied]: Unauthorized Screen-Scraping of Authentications
To: "[email protected]" <[email protected]>


Hi List:

There were two recent identified cases of unauthorized external
applications screen-scraping authentication to the University of
British Columbia's (UBC) credential system.

Case 1: A website requested users to enter their UBC credentials to
validate their UBC affiliation; upon entering of UBC credentials,
unbeknown to the user, the website programatically screen-scraped
authentications to a valid UBC student application.

Case 2: An iPhone application performed similar screen-scraped process
as described in case 1 above; in this scenario, the iOS application
also screen-scraped the user's course time-table and maintained a copy
of the user's UBC's credentials within the iPhone application.

For case 1, an IP block was placed on the UBC network which halted the
screen-scraped events; for case 2, an IP block would not have been
effective, as the screen-scraped events originate directly from the
iPhone (the dynamic IP address is derived from the telco operator, or
wireless internet connection, and pattern is not discernible).

Questions:

A. What are your institution's policies w.r.t screen-scraping of
authentications by unauthorized entities?

B.What technical processes do you have in-place to identify, or
impede, unauthorized screen-scraping of authentications?

C: For case 2, where there is an identified unauthorized activity,
what technical steps could you recommend for blocking access (whereby
distributed nature of iPhone application usage do not facilitate
blocking by IP address)?

Thank you for all feedback and direction.

Please do not hesitate to let me know if you have any questions or suggestions.

Best regards,

Hari
