A new steganography campaign targeting iOS devices exploits demand-side adtech providers and adtech vendors to serve malware to millions of consumers.
The Media Trust Digital Security and Operations team has detected that at least five publishers, three demand-side vendors, and 11 other adtech vendors have been used to spread the malware Stegoware-3PC residing in PNG files on devices using iOS 12.
