What Are the Possible Causes for Data Corruption of an RDS Instance?

Data tampering
Lots of security measures are provided to ensure that only authenticated users have permissions to perform operations on database table records. Database tables can be accessed only through specific database ports.

Verifying package during primary/standby synchronization can prevent data tampering.
DB instance servers may be powered off suddenly, causing database page corruption and database rebooting failures.
If a primary DB instance becomes faulty, the system switches to the standby DB instance within 1 to 5 minutes to provide services for you. DB instances cannot be accessed during the failover. You need to configure automatic reconnections between applications and DB instances to ensure near-continuous availability.
