While any ressource (hardware devices but also software components) normally relies on the processor (CPU) and the embedded Memory Management Unit (MMU) to read or write data to the main memory (RAM), some may have an almost direct access to this main memory.īest known as "Direct Memory Access" (DMA), the technology was created in order to guarantee optimum performance for data transfers between, for example, a system and a hardware device (remember your old videocamera).

This workstation was up to date at the time of the assessment (Windows 10 Version 1709) with a strong hardening along with an AppLocker policy very close to the state of the art.Īs the operating system did not offer an easy attack surface, another vector was used to compromise it: physical attack involving a Direct Memory Access (DMA). This blogpost will give an overview of what was possible to do on an "all in one" computer aimed to be given for teleworking matters.

Thanks in particular to Xeno Kovah ( that pointed out that Microsoft Windows does not take profit of VT-d/IOMMU properties on a stock install so far (assumption that was confirmed by, in no particular order, Alex Ionescu ( Jeremiah Cox ( and Dave Weston ( Many thanks to them!).įinally thanks to Yuriy Bulygin ( for pointing out that some references were missing regarding existing hardware attacks. Once you done that, make sure you run gpupdate /force to apply the new policy setting.We are very pleased that this blogpost had a lot of feedbacks! To fix the issue we need to remove this account from the list. So let’s see if this account exist in AD.Īs can see its not existing in AD, the error is clear. Then when go to Computer Configuration > Security Settings > Local Policies > User Rights Assignment it shows log on as a service got the faulty account applied. Then in result window it shows problem is stick with the computer configuration To do it run RSoP (Resultant Set of Policy) mmc to identify the source GPO that contain the problems. So next step is to find where it is used. This time it shows canitpro_prg1 is the account. If the log is created first time, we need to wait for some time till it collect the logs. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\Īnd then double click on key ExtensionDebugLevel and set it to 2. To find it need to run command from the domain controller as domain administratorįIND /I "Cannot find" %SYSTEMROOT%\Security\Logs\winlogon.log The first thing we need to do is find out the accounts which have problems with. But let’s see how we really can trigger down the problem.

Those accounts couldn’t resolved to correct SID.ġ) The relevant account used in the GPO is removed from AD.Ģ) Within the GPO the account name is typed incorrectly. Which means there is a GPOs setting which used for domain computers, controllers with orphaned account details. It will be visible in Event viewer > Windows Logs > Application LogĪs it describes in error it’s saying no mapping between account names and security IDs. It can be in either on domain controllers itself or the local computers.
