A new wave of cyber attacks targeting Android users has been identified, involving 224 compromised applications that have collectively amassed over 38 million downloads from the Google Play Store. This threat, named SlopAds by the Satori Threat Intelligence and Research Team, involves sophisticated advertising fraud techniques, including steganography, to generate illicit revenue through harmful ads embedded in apps. Google has removed all compromised applications from the Play Store and will notify users to uninstall them. Users are advised to enable Google’s Play Protect feature to safeguard against malicious applications. Ad fraud not only affects individual users but also undermines trust in the advertising ecosystem.
