Yahoo Groups and 3rd Party Email Registration

I've helped with product development and product sourcing for some time here in Hong Kong. This means I've attended many tech trade shows and passed out countless business cards. Since these are Chinese businesses, this provides great tests for my SpamAssassin installation.

The latest trick that certain mainland spammers have taken up is creating Yahoo groups and then signing my email address up to receive the emails for their group. Yahoo Groups does not require an email confirmation for 3rd Party signup to the Yahoo Groups. The admins in news.admin.net-abuse.email knew this was a recipe ...

OpenID vs OAuth: Successes And Failures

OpenID has officially been added to The List. Y'know, The List. The official list of things the kool kidz all mindlessly slag. Nokia, XML, W3C.

Other People's Data and Your Security Mindset

In the June 2008 issue of Computerworld Hong Kong on page 14 (not yet online), there is a write-up of the Info-Security Conference 2008 that was held at the HKCEC on May 23.

Some of the flaws addressed in these patches can be exploited in Web-based attacks where a criminal tricks the victim into visiting a malicious Web page and then takes advantage of the bug to install malicious software on the Windows PC.
