The New York Times reported on hackers exploiting Flash vulnerability in Yahoo ads.
For seven days, hackers used Yahoo’s ad network to send malicious bits of code to computers that visit Yahoo’s collection of heavily trafficked websites, the company said on Monday.
The attack, which started on July 28, was the latest in a string that have exploited Internet advertising networks, which are designed to reach millions of people online. It also highlighted growing anxiety over a much-used graphics program called Adobe Flash, which has a history of security issues that have irked developers at Silicon Valley companies.
“Right now, the bad guys are really enjoying this,” said Jérôme Segura, a security researcher at Malwarebytes, the security company that uncovered the attack. “Flash for them was a godsend.”
