Black Hat to expose attacks

摘要

The black hat conference unfolds in Las Vegas this week with an agenda set to expose exploits as varied as tapping power outlets to capture keyboard signals and closing up holes in the use of the secure protocol that protects online bank transactions. Other briefings will consider the use of lasersrnand analysis software to figure out what's being typed on laptops and detecting what damage has been done via attacks that leave no trace on computer hardrndrives.rnBlack Hat USA 2009, considered a premierrnvenue for publicizing new exploits with an eyerntoward neutralizing them, is expected to drawrnthousands to hear presentations from academics, vendors and private crackers.rnFor instance, one talk will demonstrate that if attackers can plug into an electrical socket near a computcr or draw a bead on it with a laser they can steal whatever is being typed in. How to execute this attack will be demonstrated by Andrea Barisani and Daniele Bianco, a pair of researchers for network security consultancy Inverse Path.
