The analytic detects the execution of Puppet commands with elevated privileges, specifically when Puppet is used to apply configurations with sudo rights. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs that include command-line details. This activity is significant because it indicates a potential privilege escalation attempt, where a user could gain root access and execute system commands as the root user. If confirmed malicious, this could allow an attacker to fully compromise the system, execute arbitrary commands, and maintain persistent control.
The analytic detects the execution of Ruby commands with elevated privileges on a Linux system. It identifies processes where Ruby is used with the `-e` flag to execute commands via `sudo`, leveraging Endpoint Detection and Response (EDR) telemetry. This activity is significant because it indicates a potential privilege escalation attempt, allowing a user to execute commands as root. If confirmed malicious, this could lead to full system compromise, enabling an attacker to gain root access, execute arbitrary commands, and maintain persistent control over the affected system.
The following analytic detects the execution of the sqlite3 command with elevated privileges, which can be exploited for privilege escalation. It leverages Endpoint Detection and Response (EDR) telemetry to identify instances where sqlite3 is used in conjunction with shell commands and sudo. This activity is significant because it indicates a potential attempt to gain root access, which could lead to full system compromise. If confirmed malicious, an attacker could execute arbitrary commands as root, leading to unauthorized access, data exfiltration, or further lateral movement within the network.
The following analytic detects the loading of an unsigned DLL by the MMC.exe application, which is indicative of a potential UAC bypass or privilege escalation attempt. It leverages Sysmon EventCode 7 to identify instances where MMC.exe loads a non-Microsoft, unsigned DLL. This activity is significant because attackers often use this technique to modify CLSID registry entries, causing MMC.exe to load malicious DLLs, thereby bypassing User Account Control (UAC) and gaining elevated privileges. If confirmed malicious, this could allow an attacker to execute arbitrary code with higher privileges, leading to further system compromise and persistence.
The analytic detects the execution of the 'csvtool' command with 'sudo' privileges, which can allow a user to run system commands as root. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs that include command-line details. This activity is significant because it indicates a potential privilege escalation attempt, where a user could gain unauthorized root access. If confirmed malicious, this could lead to full system compromise, allowing an attacker to execute arbitrary commands, escalate privileges, and maintain persistent access.
The analytic detects the execution of the GNU Debugger (GDB) with specific flags (`-nx`, `-ex`, and `sudo`) that indicate an attempt to escalate privileges on a Linux system. This activity can allow a user to execute system commands as root, potentially leading to a root shell and full system compromise.
The following analytic detects the execution of the RubyGems utility with elevated privileges, specifically when it is used to run system commands as root. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions that include "gem open -e" and "sudo". This activity is significant because it indicates a potential privilege escalation attempt, allowing a user to execute commands as the root user. If confirmed malicious, this could lead to full system compromise, enabling the attacker to gain root access and execute arbitrary commands with elevated privileges.
The following analytic detects the execution of PHP commands with elevated privileges on a Linux system. It identifies instances where PHP is used in conjunction with 'sudo' and 'system' commands, indicating an attempt to run system commands as the root user. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process command-line arguments. This activity is significant because it can indicate an attempt to escalate privileges, potentially leading to full root access. If confirmed malicious, this could allow an attacker to execute arbitrary commands with root privileges, compromising the entire system.
The analytic detects a process attempting to access winlogon.exe to duplicate its handle. This is identified using Sysmon EventCode 10, focusing on processes targeting winlogon.exe with specific access rights (0x1040). This activity is significant because it is a common technique used by adversaries to escalate privileges by leveraging the high privileges and security tokens associated with winlogon.exe. If confirmed malicious, this could allow an attacker to gain elevated privileges, potentially leading to full system compromise and unauthorized access to sensitive information.
This analytic detects any system integrity level process spawned by a non-system account. It leverages Sysmon EventID 1, focusing on process integrity and parent user data. This behavior is significant as it often indicates successful privilege escalation to SYSTEM from a user-controlled process or service. If confirmed malicious, this activity could allow an attacker to gain full control over the system, execute arbitrary code, and potentially compromise the entire environment.
The analytic detects the creation of the `doas.conf` file on a Linux host. This file is used by the `doas` utility to allow standard users to perform tasks as root, similar to `sudo`. The detection leverages filesystem data, focusing on the creation of the `doas.conf` file. This activity is significant because it can indicate an attempt to gain elevated privileges, potentially by an adversary. If confirmed malicious, this could allow an attacker to execute commands with root privileges, leading to full system compromise.
The following analytic detects the execution of Emacs with elevated privileges using the `sudo` command and the `--eval` option. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs that include command-line arguments. This activity is significant because it indicates a potential privilege escalation attempt, where a user could gain root access by running Emacs with elevated permissions. If confirmed malicious, this could allow an attacker to execute arbitrary commands as root, leading to full system compromise and unauthorized access to sensitive information.
The analytic detects the use of the 'make' command with elevated privileges to execute system commands as root, potentially leading to a root shell. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions that include 'make', '--eval', and 'sudo'. This activity is significant because it indicates a possible privilege escalation attempt, allowing a user to gain root access. If confirmed malicious, an attacker could achieve full control over the system, execute arbitrary commands, and compromise the entire environment.
The analytic detects when a process spawns an executable known for User Account Control (UAC) bypass exploitation and subsequently monitors for any child processes with a higher integrity level than the original process. This detection leverages Sysmon EventID 1 data, focusing on process integrity levels and known UAC bypass executables. This activity is significant as it may indicate an attacker has successfully used a UAC bypass exploit to escalate privileges. If confirmed malicious, the attacker could gain elevated privileges, potentially leading to further system compromise and persistent access.
The following analytic detects modifications to the registry aimed at bypassing the User Account Control (UAC) feature in Windows. It identifies changes to the .NET COR_PROFILER_PATH registry key, which can be exploited to load a malicious DLL via mmc.exe. This detection leverages data from the Endpoint.Registry datamodel, focusing on specific registry paths and values. Monitoring this activity is crucial as it can indicate an attempt to escalate privileges or persist within the environment. If confirmed malicious, this could allow an attacker to execute arbitrary code with elevated privileges, compromising system integrity.
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.
This rule detects a User Account Control (UAC) bypass technique that exploits a path parsing vulnerability in `winsat.exe`. Specifically, it looks for the creation of a process with 'High' or 'System' integrity levels where the parent process image path ends with `\AppData\Local\Temp\system32\winsat.exe` and the parent command line contains `C:\Windows \system32\winsat.exe`. This pattern is indicative of UACMe method 52, which leverages a specially crafted path to trick `winsat.exe` into executing an arbitrary payload with elevated privileges.
Detects the execution of the 'Impersonate' tool, which is designed to manipulate Windows tokens. This tool can be used to escalate privileges by impersonating other user tokens, either remotely (e.g., via PsExec/WmiExec) or interactively. Detection is based on specific command-line arguments or known hashes of the tool.
Detects exploitation attempts related to the Nimbuspwn privilege escalation vulnerabilities (CVE-2022-29799 and CVE-2022-29800) on Linux systems. The rule looks for specific keywords that indicate the `networkd-dispatcher` service is being manipulated, potentially to execute arbitrary code with elevated privileges.
Detects a User Account Control (UAC) bypass technique that leverages the Windows Event Viewer (eventvwr.exe). This method involves manipulating the registry to execute an arbitrary binary or script with elevated privileges when eventvwr.exe is launched. The rule specifically looks for file creation events in the 'RecentViews' directory associated with Event Viewer, where the creating process is not a standard system process (i.e., not originating from C:\Windows\System32\ or C:\Windows\SysWOW64\).
This rule detects User Account Control (UAC) bypass attempts by monitoring specific registry key modifications related to `sdclt.exe`. Attackers can manipulate these registry keys to hijack the execution flow of `sdclt.exe`, a legitimate Windows utility, to run arbitrary code with elevated privileges without triggering a UAC prompt. The rule specifically looks for modifications to `Software\Classes\exefile\shell\runas\command\isolatedCommand` or `Software\Classes\Folder\shell\open\command\SymbolicLinkValue` with a specific pattern indicating a UAC bypass technique.
