Last week malvertising also known as malicious advertising made it’s way onto popular websites such as Yahoo finanace, Fantasy Sports sites, realestate.aol.com, theatlantic.com, 9gag.com and match.com. The malvertising was discovered by Proofpoint and had an impact on visitors who were potentially exposed to this malvertising. The sites themselves were not compromised but the malvertising ads were able to push their way through three major advertising networks and exchanges. The ads were impersonating legitimate ads such as Microsoft Bing, Fancy and Case Logic. If your computer has outdated plug-ins the malvertising ad puts a ransonware program called CryptoWall 2.0 on the user’s computer. Then you are asked to pay a ransom in Bitcoin cryptocurrency. These attacks received about $25,000.00 a day in Bitcoin. For more information on this blog click on this link.
