CopyCat is an Android malware that generates and steals ad revenue. According to CyberScoop, the malware infected 14 million Android devices, rooted 8 million phones and had 3.8 million devices serve ads. It claimed victims mainly in South and Southeast Asia, but over 280,000 Android users in the United States were also infected. CopyCat infects users through dated exploits, the oldest dating back to 2013. The danger of CopyCat is its modular structure, which allows the threat actor to change the malware’s strategy and behavior on the device to be tailored to their victims. Researchers at Check Point Software Technologies state that CopyCat is a fully developed malware with many capabilities, including elevating privileges to root, establishing persistency, and injecting code into Zygote which allows the malware to intervene in any activity on the device.
