A recent cyber attack on advertising network NetSeer had an unusally broad impact, causing Google to issue malware warnings for many of the sites that delivered its ads.

"A NetSeer spokesperson confirmed that its corporate network had been infected with malware, and Google subsequently added its domain to a list of malware-affected Websites," writes ZDNet's Zack Whittaker. "Because NetSeer's corporate site has the same domain name as its advertising network, Google triggered warnings on end-user machines warning users to avoid any Web page that happened to include an ad served from NetSeer's servers."

"Sites like The New York Times, The Washington Post, Boston.com, ZDNet, IMDB, and The Hollywood Reporter were among the dozens of sites that were said to be put on the blacklist, preventing users from visiting their pages," writes The Verge's Dante D'Orazio.

"Meanwhile, NetSeer claims it has removed all the malware from its own website and is working with Google throughout the day to take its domain off the Chrome blacklist, as the company explained in a statement: 'Our operations team went into all-hands-on-deck mode and we have successfully cleaned the site of the malware issue. We are also working with Google to do an expedited review of the site and remove the site from the malware impacted site-list so that browsing behavior can be restored for all users,'" writes The Atlantic Wire's Rebecca Greenfield.
