Adversaries may insert, delete, or manipulate data in order to manipulate external outcomes or hide activity. By manipulating data, adversaries may attempt to affect a business process, organizational understanding, or decision making.
The type of modification and the impact it will have depends on the target application and process 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 that would typically be gained through a prolonged information gathering campaign in order to have the desired impact.
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
Where applicable, inspect important file hashes, locations, and modifications for suspicious/unexpected values. With some critical processes involving transmission of data, manual or out-of-band integrity checking may be useful for identifying manipulated data.
