DEFCON exposes web vulnerabilities

Presenters at last weekend's DEFCON conference in Las Vegas published security vulnerabilities affecting most of today's social Web. Security researchers demonstrated taking over a social networking account, collecting user names and passwords, and gaining access to remote computers using popular audio and video players.

Amazon launches Flexible Payment Service

Amazon Web Services launched a new payment service last week extending Amazon.com payment processing services to any developer on the Web. Third-party applications can quickly market services to Amazon's 69 million active customers with one-click checkouts and pre-stored payment information.

Viddler introduces groups

Video sharing site Viddler now connects publishers of similar interests through affinity groups. Site members can join a group covering topics such as coffee, music, or a recent event. Publishers can share new videos with group members for review and commentary.

Justin.tv redesign

Live video sharing site Justin.tv upgraded its site last week with new video browsing features and user submissions. The new video bar highlights video content from across the site's range of publishers and supports direct video playback.
