NTFS File Attributes Mitigation

It may be difficult or inadvisable to block access to EA and ADSs.^[1],[2] Efforts should be focused on preventing potentially malicious software from running. Identify and block potentially malicious software that may contain functionality to hide information in EA and ADSs by using whitelisting^[3] tools like AppLocker^[4],[5] or Software Restriction Policies^[6] where appropriate.^[7]

Consider adjusting read and write permissions for NTFS EA, though this should be tested to ensure routine OS operations are not impeded.^[8]
