Detecting Active Services Sandbox Evasion
VMwareService.exe runs the VMware Tools Service as a child of services.exe. It can be identified by listing services.
Hijack Execution Flow: Services File Permissions Weakness Defense Evasion [Mitre]
Adversaries may execute their own malicious payloads by hijacking the binaries used by services. Adversaries may use flaws in the permissions of Windows services to replace the binary that is executed upon service start. These service processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory …
Hijack Execution Flow: Services Registry Permissions Weakness Defense Evasion [Mitre]
Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Adversaries may use flaws in the permissions for Registry keys related to services to redirect from the originally specified executable to one that they control, in order to launch their own code when a service starts. Windows stores local service configuration information in the Registry …
Killing Windows Event Log Anti-Forensic
Killing the Windows Event Log is a technique used by malware to prevent security professionals from detecting and analyzing it. Svchost.exe is a process that manages services on Windows operating systems.
By grouping multiple services into a single process, Svchost.exe conserves computing resources and reduces resource consumption. However, this also means that Svchost.exe manages the Event Log service, which …
Modify Authentication Process: Hybrid Identity Defense Evasion [Mitre]
Adversaries may patch, modify, or otherwise backdoor cloud authentication processes that are tied to on-premises user identities in order to bypass typical authentication mechanisms, access credentials, and enable persistent access to accounts.
Many organizations maintain hybrid user and device identities that are shared between on-premises and cloud-based environments. These can be maintained in a number of ways. For example, …
Valid Accounts: Domain Accounts Defense Evasion [Mitre]
Adversaries may obtain and abuse credentials of a domain account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Domain accounts are those managed by Active Directory Domain Services where access and permissions are configured across systems and services that are part of that domain. Domain accounts can cover users, administrators, and services.
Adversaries may …
Detecting Virtual Environment Process Sandbox Evasion
Process related to Virtualbox can be detected by malware by query the process list.
The VMware Tools use processes like VMwareServices.exe or VMwareTray.exe, to perform actions on the virtual environment. A malware can list the process and searches for the VMware string. Process: VMwareService.exe, VMwareTray.exe, TPAutoConnSvc.exe, VMtoolsd.exe, VMwareuser.exe.
Windows Event Log Evasion via Native APIs Anti-Forensic
Attackers can leverage native Windows API calls to install malicious services without generating correlating entries in the event log. Using native APIs to install services instead of the standard API calls allow attackers to bypass security controls and event logging. This technique was utilised by Stuxnet.
Services are typically created through a standard Windows API call CreateServiceA or CreateService …
Access Token Manipulation: SID-History Injection Defense Evasion [Mitre]
Adversaries may use SID-History Injection to escalate privileges and bypass access controls. The Windows security identifier (SID) is a unique value that identifies a user or group account. SIDs are used by Windows security in both security descriptors and access tokens. An account can hold additional SIDs in the SID-History Active Directory attribute, allowing inter-operable account migration between domains (e.g., …
Impair Defenses: Disable or Modify Tools Defense Evasion [Mitre]
Adversaries may modify and/or disable security tools to avoid possible detection of their malware/tools and activities. This may take many forms, such as killing security software processes or services, modifying / deleting Registry keys or configuration files so that tools do not operate properly, or other methods to interfere with security tools scanning or reporting information. Adversaries may also disable …
