Overview
This problem occurs when the Genymotion PaaS/Device image instance has been hacked and compromised via TCP port 5555.
An ADB connection is not secured.
An ADB connection is not authenticated.
If the instance inbound rules allow connections from anyone, the ADB interface becomes exposed.
If TCP port 5555 is open to anyone (0.0.0.0/0) and ADB access is enabled, then anyone can connect to the ADB interface.
In such cases, a malicious user can inject software or corrupt the device.
Remediation steps
If you are affected, delete your Genymotion PaaS/Device image instances as soon as possible.
Use one of the following methods to secure ADB connections:
- Adjust EC2 firewall rules to restrict access to authorized hosts only.
- Refer to Network Security Settings for more details.
- Block inbound connections to TCP port 5555.
- Use an SSH tunnel.
