Updated 10 a.m. PDT Tuesday with comment from "Mox."
Someone exploited a weakness in Democratic presidential hopeful Barack Obama's Web site and redirected visitors to rival Hillary Clinton's site over the weekend, according to a posting on the blog of security firm NetCraft.
Basically, visitors to the community blogs section of Obama's site on Saturday night were sent to Clinton's site. Someone using the alias "Mox" claimed credit for the hack on Obama's site late on Sunday.
The writer downplayed the act, saying: "All I did was exploit some poorly written HTML code." Basically, the hack was possible because of a cross-site scripting vulnerability, which is a common hole in Web sites.
A YouTube user named "Zennie62" posted a video clip showing him being redirected from Obama's site to Clinton's.
The redirect has been fixed, but "Mox" says similar vulnerabilities remain on the site.
