Transmitted Data Manipulation
Where this stands
No Sigma rule can address this — the telemetry MITRE names has no Sigma logsource behind it.
Sigma has no logsource taxonomy for mobile platforms. MITRE's telemetry here is mobile EDR and device APIs, which no Sigma rule can address.
What the technique is
Adversaries may alter data en route to storage or other systems in order to manipulate external outcomes or hide activity. By manipulating transmitted data, adversaries may attempt to affect a business process, organizational understanding, or decision making. Manipulation may be possible over a network connection or between system processes where there is an opportunity to deploy a tool that will intercept and change information. The type of modification and the impact it will have depends on the target transmission mechanism as well as the goals and objectives of the adversary. For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system, typically gained through a prolonged information gathering campaign, in order to have the desired impact. One method to achieve Transmitted Data Manipulation is by modifying the contents of the device clipboard. Malicious applications may monitor clipboard activity through the ClipboardManager.OnPrimaryClipChangedListener interface on Android to determine when clipboard contents have changed. Listening to clipboard activity, reading clipboard contents, and modifying clipboard contents requires no explicit application permissions and can be performed by applications running in the background. However, this behavior has changed with the release of Android 10. […]

Applications could be vetted for their use of the clipboard manager APIs with extra scrutiny given to application that make use of them.
