Binary Defense analysts have also tracked the sale of the Rogue Android RAT on criminal forums since early last year. Although Rogue has not been offered for sale recently, other forms of Android malware have been available and are often discussed on criminal forums. To avoid becoming a victim of mobile malware, first ensure that mobile devices always have the latest security update. Doing so will prevent it from being subject to known vulnerabilities. Avoid apps that are downloaded from websites or links from email and text messages—Android users should stick to Google Play and only install apps that have been available for at least a few weeks with positive reviews. Additionally, be wary of apps that ask for an excessive number of permissions to run on the device, especially device administrator or accessibility permissions. Be aware of social engineering campaigns—threat actors often try to collect data through phishing texts and emails. Always verify the source when being asked for personal information and contact the organization directly if something seems suspicious.
