Account Manipulation

Adversaries may manipulate accounts to maintain access to victim systems. Account manipulation may consist of any action that preserves adversary access to a compromised account, such as modifying credentials or permission groups. These actions could also include account activity designed to subvert security policies, such as performing iterative password updates to bypass password duration policies and preserve the life of compromised credentials.

In order to create or manipulate accounts, the adversary must already have sufficient permissions on systems or the domain. However, account manipulation may also lead to privilege escalation where modifications grant access to additional roles, permissions, or higher-privileged Valid Accounts.

Procedure Examples

ID Name Description
G0022 APT3

APT3 has been known to add created accounts to local admin groups to maintain elevated access.[1]

S0274 Calisto

Calisto adds permissions and remote logins to all users.[2]

G0035 Dragonfly

Dragonfly has added newly created accounts to the administrators group to maintain elevated access.[3]

G0094 Kimsuky

Kimsuky has added accounts to specific groups with net localgroup.[4]

G0032 Lazarus Group

Lazarus Group malware WhiskeyDelta-Two contains a function that attempts to rename the administrator’s account.[5][6]

S0002 Mimikatz

The Mimikatz credential dumper has been extended to include Skeleton Key domain controller authentication bypass functionality. The LSADUMP::ChangeNTLM and LSADUMP::SetNTLM modules can also manipulate the password hash of an account without knowing the clear text value.[7][8]

G0034 Sandworm Team

Sandworm Team used the sp_addlinkedsrvlogin command in MS-SQL to create a link between a created account and other servers in the network.[9]


SMOKEDHAM has added created user accounts to local Admin groups.[10]


ID Mitigation Description
M1032 Multi-factor Authentication

Use multi-factor authentication for user and privileged accounts.

M1030 Network Segmentation

Configure access controls and firewalls to limit access to critical systems and domain controllers. Most cloud environments support separate virtual private cloud (VPC) instances that enable further segmentation of cloud systems.

M1028 Operating System Configuration

Protect domain controllers by ensuring proper security configuration for critical servers to limit access by potentially unnecessary protocols and services, such as SMB file sharing.

M1026 Privileged Account Management

Do not allow domain administrator accounts to be used for day-to-day operations that may expose them to potential adversaries on unprivileged systems.


ID Data Source Data Component
DS0026 Active Directory Active Directory Object Modification
DS0017 Command Command Execution
DS0022 File File Modification
DS0036 Group Group Modification
DS0009 Process Process Creation
DS0002 User Account User Account Modification

Collect events that correlate with changes to account objects and/or permissions on systems and the domain, such as event IDs 4738, 4728 and 4670.[11][12][12] Monitor for modification of accounts in correlation with other suspicious activity. Changes may occur at unusual times or from unusual systems. Especially flag events where the subject and target accounts differ[13] or that include additional flags such as changing a password without knowledge of the old password.[14]

Monitor for use of credentials at unusual times or to unusual systems or services. This may also correlate with other suspicious activity.

Monitor for unusual permissions changes that may indicate excessively broad permissions being granted to compromised accounts. However, account manipulation may also lead to privilege escalation where modifications grant access to additional roles, permissions, or higher-privileged Valid Accounts
