Sigma Rules
889 rules found for "persistence"
Suspicious Get-Variable.exe Creation
Get-Variable is a valid PowerShell cmdlet WindowsApps is by default in the path where PowerShell is executed. So when the Get-Variable command is issued on PowerShell execution, the system first looks for the Get-Variable executable in the path and executes the malicious binary instead of looking for the PowerShell cmdlet.
PowerShell Profile Modification
Detects the creation or modification of a powershell profile which could indicate suspicious activity as the profile can be used as a mean of persistence
Suspicious File Creation Activity From Fake Recycle.Bin Folder
Detects file write event from/to a fake recycle bin folder that is often used as a staging directory for malware
Suspicious Startup Folder Persistence
Detects the creation of potentially malicious script and executable files in Windows startup folders, which is a common persistence technique used by threat actors. These files (.ps1, .vbs, .js, .bat, etc.) are automatically executed when a user logs in, making the Startup folder an attractive target for attackers. This technique is frequently observed in malvertising campaigns and malware distribution where attackers attempt to maintain long-term access to compromised systems.
Suspicious Scheduled Task Write to System32 Tasks
Detects the creation of tasks from processes executed from suspicious locations
VsCode Powershell Profile Modification
Detects the creation or modification of a vscode related powershell profile which could indicate suspicious activity as the profile can be used as a mean of persistence
Windows Terminal Profile Settings Modification By Uncommon Process
Detects the creation or modification of the Windows Terminal Profile settings file "settings.json" by an uncommon process.
Process Explorer Driver Creation By Non-Sysinternals Binary
Detects creation of the Process Explorer drivers by processes other than Process Explorer (procexp) itself. Hack tools or malware may use the Process Explorer driver to elevate privileges, drops it to disk for a few moments, runs a service using that driver and removes it afterwards.
Process Monitor Driver Creation By Non-Sysinternals Binary
Detects creation of the Process Monitor driver by processes other than Process Monitor (procmon) itself.
PSEXEC Remote Execution File Artefact
Detects creation of the PSEXEC key file. Which is created anytime a PsExec command is executed. It gets written to the file system and will be recorded in the USN Journal on the target system
Potential Privilege Escalation Attempt Via .Exe.Local Technique
Detects potential privilege escalation attempt via the creation of the "*.Exe.Local" folder inside the "System32" directory in order to sideload "comctl32.dll"
Potential Webshell Creation On Static Website

Creation of WerFault.exe/Wer.dll in Unusual Folder
Detects the creation of a file named "WerFault.exe" or "wer.dll" in an uncommon folder, which could be a sign of WerFault DLL hijacking.
WinRAR Creating Files in Startup Locations
Detects WinRAR creating files in Windows startup locations, which may indicate an attempt to establish persistence by adding malicious files to the Startup folder. This kind of behaviour has been associated with exploitation of WinRAR path traversal vulnerability CVE-2025-6218 or CVE-2025-8088.
WMI Persistence - Script Event Consumer File Write
Detects file writes of WMI script event consumer
UEFI Persistence Via Wpbbin - FileCreation
Detects creation of a file named "wpbbin" in the "%systemroot%\system32\" directory. Which could be indicative of UEFI based persistence method
Writing Local Admin Share
Aversaries may use to interact with a remote network share using Server Message Block (SMB). This technique is used by post-exploitation frameworks.
Potential Azure Browser SSO Abuse
Detects abusing Azure Browser SSO by requesting OAuth 2.0 refresh tokens for an Azure-AD-authenticated Windows user (i.e. the machine is joined to Azure AD and a user logs in with their Azure AD account) wanting to perform SSO authentication in the browser. An attacker can use this to authenticate to Azure AD in a browser as that user.
Unsigned .node File Loaded
Detects the loading of unsigned .node files. Adversaries may abuse a lack of .node integrity checking to execute arbitrary code inside of trusted applications such as Slack. .node files are native add-ons for Electron-based applications, which are commonly used for desktop applications like Slack, Discord, and Visual Studio Code. This technique has been observed in the DripLoader malware, which uses unsigned .node files to load malicious native code into Electron applications.
Microsoft VBA For Outlook Addin Loaded Via Outlook
Detects outlvba (Microsoft VBA for Outlook Addin) DLL being loaded by the outlook process
WMI ActiveScriptEventConsumers Activity Via Scrcons.EXE DLL Load
