CoolReaper: The Coolpad Backdoor
New research from Unit 42 confirms security risk in Coolpad devices
Palo Alto Networks researchers have uncovered CoolReaper, a backdoor contained in millions of Android devices sold by manufacturer Coolpad. CoolReaper exposes users to potential malicious activity and appears to have been installed and maintained by Coolpad despite objections from customers.
Due to the unique way Coolpad modifies the Android OS, it is difficult for Android antivirus programs to identify and remove this backdoor.
