An adversary may use legitimate desktop support and remote access software, such as Team Viewer, Go2Assist, LogMein, AmmyyAdmin, etc, to establish an interactive command and control channel to target systems within networks. These services are commonly used as legitimate technical support software, and may be allowed by application control within a target environment. Remote access tools like VNC, Ammyy, and Teamviewer are used frequently when compared with other legitimate software commonly used by adversaries. (Citation: Symantec Living off the Land)

Azure Kubernetes Admission Controller

Aug 12, 2024 · attack.persistence attack.t1078 attack.credential-access attack.t1552 attack.t1552.007 ·

Share on:

Identifies when an admission controller is executed in Azure Kubernetes. A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server. The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster. An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster. For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod. An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials. An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.

The DSRM account is an “Administrator” account that logs in with the DSRM mode when the server is booting up to restore AD backups or recover the server from a failure. Attackers could abuse DSRM account to maintain their persistence and access to the organization's Active Directory. If the "DsrmAdminLogonBehavior" value is set to "0", the administrator account can only be used if the DC starts in DSRM. If the "DsrmAdminLogonBehavior" value is set to "1", the administrator account can only be used if the local AD DS service is stopped. If the "DsrmAdminLogonBehavior" value is set to "2", the administrator account can always be used.

Share on:

Detects when an attacker tries to disable User Account Control (UAC) notification by tampering with the "UACDisableNotify" value. UAC is a critical security feature in Windows that prevents unauthorized changes to the operating system. It prompts the user for permission or an administrator password before allowing actions that could affect the system's operation or change settings that affect other users. When "UACDisableNotify" is set to 1, UAC prompts are suppressed.

UAC Secure Desktop Prompt Disabled

Aug 12, 2024 · attack.privilege-escalation attack.defense-evasion attack.t1548.002 ·

Share on:

Detects when an attacker tries to change User Account Control (UAC) elevation request destination via the "PromptOnSecureDesktop" value. The "PromptOnSecureDesktop" setting specifically determines whether UAC prompts are displayed on the secure desktop. The secure desktop is a separate desktop environment that's isolated from other processes running on the system. It's designed to prevent malicious software from intercepting or tampering with UAC prompts. When "PromptOnSecureDesktop" is set to 0, UAC prompts are displayed on the user's current desktop instead of the secure desktop. This reduces the level of security because it potentially exposes the prompts to manipulation by malicious software.

Arbitrary code execution and remote sessions via Action1 RMM

Aug 10, 2024 · attack.CommandAndControl attack.T1219 ·

Share on:

Action1 is a powerful Remote Monitoring and Management tool that enables users to execute commands, scripts, and binaries. Through the web interface of action1, the administrator must create a new policy or an app to establish remote execution and then points that the agent is installed. Hunting Opportunity 1- Weed Out The Noise --- When threat actors execute a script, a command, or a binary through these new policies and apps, the names of these become visible in the command line during the execution process. Below is an example of the command line that contains the deployment of a binary through a policy with name "test_app_1": ParentCommandLine: "C:\WINDOWS\Action1\action1_agent.exe schedule:Deploy_App__test_app_1_1681327673425 runaction:0"

After establishing a baseline, we can split the command to extract the policy name and group all the policy names and inspect the results with a list of frequency occurrences. An example query of this in Splunk could be: Index="" source="" Image="*\action1_agent.exe" ParentCommandLine="runaction:0" | rex field=ParentCommandLine "(?<=Deploy_App__)(?.(?=(_1)))"

Hunting Opportunity 2 - Remote Sessions On Out Of Office Hours ---- If you have admins within your environment using remote sessions to administer endpoints, you can create a threat-hunting query and modify the time of the initiated sessions looking for abnormal activity.

SamAccountName Spoofing and Domain Controller Impersonation

Aug 10, 2024 · attack.privilege_escalation attack.t1068 ·

Share on:

'This technique is to detect exploitation chain of CVE-2021-42287 (samAccountName Spoofing) and CVE-2021-42278 (Domain Controller Impersonation). It is looking into event 4781 for evidence of a new computer account creation and account rename that matches the name of a domain controller account without ending in "$". Computer account names always end with $ and a change like this is highly unusual. Immediately after the 4781 event, a Kerberos Ticket Granting Ticket (TGT) must be requested on behalf of the newly created and renamed computer account. A computer account name event will occur before this TGT request. Putting everything together, we may use events 4781 and 4768 to look for a series of events in which the new computer account on event 4781 matches the requested account on event 4768. NOTE-- On selection2, the TargetUserName should equal to NewTargetUserName. I have left it as a placeholder but this should change dependingon the backend you are translating the query to. Splunk Example-- | eval RenamedComputerAccount = coalesce(New_Account_Name, mvindex(Account_Name,0)) | transaction RenamedComputerAccount endswith=(EventCode=4781)'
