In addition, as soon as information has been packaged up and sent to the C2, archive files are deleted in an effort to stay undetected.

Limiting the use of mobile connectivity is a way to prevent users from suspecting their device has been compromised. 'When the victim is using Wi-Fi, all the stolen data from all the folders are sent to the C2, whereas when the victim is using a mobile data connection, only a specific set of data is sent to C2,' the researchers note. However, considering some content - such as videos - can be too large to steal without impacting connectivity, thumbnails alone are exfiltrated. The RAT will also attempt to steal files from external storage.

The team says that data exfiltration is triggered once a condition has been met, including the addition of a new mobile contact, a new app is installed, or on receipt of an SMS message. Once installed, the victim's device is registered with a Firebase command-and-control (C2) server used to issue commands while a separate, dedicated C2 is used to manage data theft. It should be noted that the sample app detected by the team was found on a third-party repository and not the official Google Play Store. A new, 'sophisticated' Android spyware app disguising itself as a software update has been discovered by researchers.Īccording to Zimperium zLabs, the malware masquerades as a System Update application while quietly exfiltrating user and handset data.
