Searching for a hot news topic or buzzword can lead an unsuspecting person to harmful malware, said Dan Hubbard, CTO of Websense, at the Cloud Security Alliance Summit, which took place at the Black Hat security conference in Las Vegas.

Estimates have suggested that about 14 percent of traditional searches for trending news go to sites hosting malware.

Much of the problem stems from the nature of information provided in real time, Hubbard says. It’s noisy, spammy, and not authoritative. So search engines have a difficult task ahead determining what links can be trusted.
