Malicious code hidden in online advertising images, publishers and ad networks cost $ 1.13 billion this year – MacDailyNews



"Malvertising, the practice of building malicious code into apparently innocent online ads, evolves through the use of steganography," reports Charlie Osborne for ZDNet. "Files, messages, pictures, and video can be hidden in content in the same format, potentially leading to malicious redirects and downloading of usage sets."

"The steganographic technique has quickly become a popular method for fraudsters to deep legitimate ad networks and spread malvertising over legitimate domains, according to GeoEdge researchers, with a new series of events highlighting the capabilities of the method," Osborne reports. "GeoEdge says that Experian had one of his legitimate ads targeted with a second image, one that was not visible to the user, but hidden inside the ad request that called the embedded malicious code. & # 39; When the ad appears on a user's desktop or phone, malicious code is enabled, researchers say. "In this case, the malicious code was an automatic redirection to a phishing site as targeted U.S. users." "

" GeoEdge estimates auto redirect and steganography techniques used to counterfeit cost publishers $ 1

20 million over the past year and marketers up to $ 920 million. Overall, the company believes that online advertisers lost $ 1.13 billion in 2018 – and this figure is expected to increase by up to a third in 2019, "reports Osborne. "Malvertising is a well-known issue, including Facebook, The New York Times BBC, AOL and MSN, among many others, have been targeted earlier."

MacDailyNews Take: The larger ad networks seem to have a better handle of unwanted, hidden redirects (think about App Store popups and auto redirects) too late. Hopefully, detection techniques will be improved and new developed to deprive the fraudsters who have legitimate ad networks.
