Computer scientists predict hack attacks before they happen
A pair of Carnegie Mellon University computer scientists have developed a tool they say will be able to predict whether or not a website will be subjected to malicious attacks in the future.

“We are able to correctly predict that sites will eventually become compromised within one year while achieving a true positive rate of 66% and a false positive rate of 17%,” the researchers wrote in a paper, “Automatically Detecting Vulnerable Websites Before They Turn Malicious.”

To predict and detect vulnerable websites, the researchers came up with a classification algorithm (called a classifier) and trained it on 444,519 archive sites containing 4,916,203 webpages.
