![]() Thus, Microsoft created a mechanism so that applications they trust will avoid triggering the UAC prompt. Microsoft doesn’t want their own applications triggering lots of pop-up UAC prompts. When these tactics have been reported to Microsoft’s bug bounty program, the Microsoft response has been “UAC is not a security boundary”. Over the years, numerous security researchers and threat actors have successfully explored ways to run their tools without triggering UAC. While many folks continue to portray UAC as a security boundary, technically, it isn’t. ![]() In fact, Microsoft describes UAC as “a fundamental component of Microsoft's overall security vision”. UAC Problem #2 – User Account Control is not actually a security boundaryīefore you scroll to the top of the article to check if I am contradicting myself, I said earlier that UAC is a security feature not a boundary. Likely the user is just trying to complete a task, and the UAC prompt just gets in the way. What changes is the Microsoft Management Console trying to make and why? The user might not know what an application does or what a verified publisher is, let alone what level of privilege is appropriate. While this is a way to turn-off UAC prompts, it is dangerous because it removes any user warning or control over what task is being granted privileges.įinally, some UAC prompts may seem ambiguous to the end user. In the worst case, a user with local admin privileges might decide to disable UAC by changing the default setting from ‘notify me’ to ‘never notify’. MFA fatigue attacks over the past year, such as from the Lapsus$ group, have effectively used a similar strategy to breach at least several high-profile company networks. If the user clicks ‘No’, prompts may continue to relaunch until the user finally acquiesces and clicks ‘Yes’. When a prompt pops up, muscle memory clicks in and the user hits ‘yes’ to get rid of the pop up. Users are also ‘click blind’, having likely approved hundreds of such messages over the years. This means an attacker must simply convince the user to run the malware via a social engineering attack, creating fake software or using innocent sounding file names like “Windows Updater.exe”. When a user is a local admin, they control what gets assigned admin tokens simply by clicking ’Yes‘. UAC Problem #1 – The user is still a local admin But wait, this isn’t the end of the story. Thus, we seem to have an effective security feature in place. Since the majority of applications don’t need an admin token to function, users aren’t bombarded with pop ups. In addition, user account control reduces the risk of an attacker acquiring an admin token without triggering a message to the user for approval. Insertion of the UAC step helps minimize the number of applications running with admin tokens that an attacker can exploit. So, when an application with an admin token is compromised, an attacker can inflict considerable damage. The admin token then enables the application to run with a high level of privilege.Īn admin token is like an ‘access all areas’ pass that allows the application to do almost anything on the system. ![]() If the user clicks “yes” on the UAC prompt to proceed with execution of their request, then an admin token is issued. However, when an application specifically requests an admin token, by default, it triggers a UAC prompt message to appear. Initially, only a standard token is issued. The principle behind Windows UAC is to give local administrators two tokens, one standard token and one admin token. This token defines the privileges and access for the application.
