Sign of the times
U.S. President Barack Obama ran a successful Web 2.0 campaign last year. Now, as president, he's got to deal with a very Web 2.0 problem: hackers abusing the social-networking features of his Web site.
Hackers have registered bogus accounts on Obama's online community, my.barackobama.com, where they are posting images designed to set off a chain of events that lead to malicious Trojan horse programs. These programs are stepping stones used by hackers to download more and more malware onto a victim's computer.
