EyeWonder Malware Incident Affects Popular Web Sites
Dancho Danchev writes on the ZDNet "Zero day" Blog:
During the last couple of hours, visitors of popular and high trafficked web sites such as CNN, BBC, Washington Post, Gamespot, WorldOfWarcraft, Mashable, Chow.com, ITpro.co.uk, AndroidCommunity; Engadget and Chip.de, started reporting that parts of the web sites are unreachable due to malware warnings appearing through the EyeWonder interactive digital advertising provider.More here.
Let’s assess the butterfly effect of a single malware incident affecting an ad network whose ads get syndicated across the entire Web.
What originally started as “we have been mistakenly flagged as malware“, briefly turned into “appears the EW.com domain was potentially maliciously “hacked” causing these errant and erroneous alerts to appear” malware incident.
Is the EyeWonder attack a typical malvertising campaign where malicious content is pushed on legitimate sites through the ad network, or did their web site actually got compromised in the ongoing Cold Fusion web sites compromise attack?
Sadly, it could be an indication of both, since I managed to reproduce the actual exploit serving attack at the Washington Post, using the exact link given by an affected reader within the comments of the article. However, what might have triggered the actual badware alert appears to a compromise of the site itself.
