Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.[2][3] By manipulating stored data, adversaries may attempt to affect a business process, organizational understanding, and decision making.

Stored data could include a variety of file formats, such as Office files, databases, stored emails, and custom file formats. The type of modification and the impact it will have depends on the type of data 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.

Detection

Mitigations (3)

M1022 Restrict File and Directory Permissions

Ensure least privilege principles are applied to important information resources to reduce exposure to data manipulation risk.

M1029 Remote Data Storage

Consider implementing IT disaster recovery plans that contain procedures for taking regular data backups that can be used to restore organizational data.[1] Ensure backups are stored off system and is protected from common methods adversaries may use to gain access and manipulate backups.

M1041 Encrypt Sensitive Information

Consider encrypting important information to reduce an adversary’s ability to perform tailored data modifications.
