Mobile Cyberespionage Campaign Distributed Through CallerSpy Mounts Initial Phase of a Targeted Attack

We found a new spyware family disguised as chat apps on a phishing website. We believe that the apps, which exhibit many cyberespionage behaviors, are initially used for a targeted attack campaign. We first came across the threat in May on the site http://gooogle.press/, which was advertising a chat app called “Chatrious.” Users can download the malicious Android application package (APK) file by clicking the download button indicated on the site.
