Cyberespionage operation targets Android users in the Middle East
ZooPark is a cyberespionage operation that has been focusing on Middle Eastern targets since at least June 2015. The threat actors behind the operation infect Android devices using several generations of malware, with the attackers including new features in each iteration. We label them from v1-v4, with v4 being the most recent version deployed in 2017.
From the technical point of view, the evolution of ZooPark has shown notable progress: from the very basic first and second versions, the commercial spyware fork in its third version and then to the complex spyware that is version 4. This last step is especially interesting, showing a big leap from straightforward code functionality to highly sophisticated malware.
