Malware infects computers

WASHINGTON – If you enjoy browsing one of the most popular sites on the Internet, you may want to check your computer for malware.

According to The New York Times, hackers used Yahoo’s ad network to send malware to visitors’ computers.

The Times says a group of hackers purchased ads across Yahoo’s platforms. When a computer running Windows visited a Yahoo site, it downloaded malware code.

“From there, the malware hunted for an out-of-date version of Adobe Flash, which it could use to commandeer the computer- either holding it for ransom until the hackers were paid off or discreetly directing its browser to websites that paid the hackers for traffic,” the site said.

Yahoo acknowledged the attack, but says it was not nearly as expansive as it was originally reported by Malwarebytes, the company that uncovered the problem.

“We take all potential security threats seriously,” a spokeswoman said in a statement. “With that said, the scale of the attack was grossly misrepresented in initial media reports, and we continue to investigate the issue.”

Officials with Malwarebytes said they couldn’t determine how many people were affected, but said that it was “one of the largest attacks we’ve seen in recent months.”
