EXPLORE DETECTIONS
Potential ShellDispatch.DLL Functionality Abuse
Detects potential "ShellDispatch.dll" functionality abuse to execute arbitrary binaries via "ShellExecute"
Potential ShellDispatch.DLL Sideloading
Detects potential DLL sideloading of "ShellDispatch.dll"
Potential Shim Database Persistence via Sdbinst.EXE
Detects installation of a new shim using sdbinst.exe. Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by application shims
Potential Sidecar Injection Into Running Deployment
Detects attempts to inject a sidecar container into a running deployment. A sidecar container is an additional container within a pod, that resides alongside the main container. One way to add containers to running resources like Deployments/DeamonSets/StatefulSets, is via a "kubectl patch" operation. By injecting a new container within a legitimate pod, an attacker can run their code and hide their activity, instead of running their own separated pod in the cluster.
Potential Signing Bypass Via Windows Developer Features
Detects when a user enable developer features such as "Developer Mode" or "Application Sideloading". Which allows the user to install untrusted packages.
Potential Signing Bypass Via Windows Developer Features - Registry
Detects when the enablement of developer features such as "Developer Mode" or "Application Sideloading". Which allows the user to install untrusted packages.
Potential SmadHook.DLL Sideloading
Detects potential DLL sideloading of "SmadHook.dll", a DLL used by SmadAV antivirus
Potential SMB Relay Attack Tool Execution
Detects different hacktools used for relay attacks on Windows for privilege escalation
Potential SolidPDFCreator.DLL Sideloading
Detects potential DLL sideloading of "SolidPDFCreator.dll"
Potential SpEL Injection In Spring Framework
Detects potential SpEL Injection exploitation, which may lead to RCE.
Potential SPN Enumeration Via Setspn.EXE
Detects service principal name (SPN) enumeration used for Kerberoasting
Potential SSH Tunnel Persistence Install Using A Scheduled Task
Detects the creation of new scheduled tasks via commandline, using Schtasks.exe. This rule detects tasks creating that call OpenSSH, which may indicate the creation of reverse SSH tunnel to the attacker's server.
Potential Startup Shortcut Persistence Via PowerShell.EXE
Detects PowerShell writing startup shortcuts. This procedure was highlighted in Red Canary Intel Insights Oct. 2021, "We frequently observe adversaries using PowerShell to write malicious .lnk files into the startup directory to establish persistence. Accordingly, this detection opportunity is likely to identify persistence mechanisms in multiple threats. In the context of Yellow Cockatoo, this persistence mechanism eventually launches the command-line script that leads to the installation of a malicious DLL"
Potential Suspicious Activity Using SeCEdit
Detects potential suspicious behaviour using secedit.exe. Such as exporting or modifying the security policy
Potential Suspicious BPF Activity - Linux
Detects the presence of "bpf_probe_write_user" BPF helper-generated warning messages. Which could be a sign of suspicious eBPF activity on the system.
Potential Suspicious Browser Launch From Document Reader Process
Detects when a browser process or browser tab is launched from an application that handles document files such as Adobe, Microsoft Office, etc. And connects to a web application over http(s), this could indicate a possible phishing attempt.
Potential Suspicious Change To Sensitive/Critical Files
Detects changes of sensitive and critical files. Monitors files that you don't expect to change without planning on Linux system. These files include, but are not limited to, system configuration files, authentication files, and critical application files. Attackers often target these files to maintain persistence, escalate privileges, or disrupt system operations.
Potential Suspicious Execution From GUID Like Folder Names
Detects potential suspicious execution of a GUID like folder name located in a suspicious location such as %TEMP% as seen being used in IcedID attacks. Use this rule to hunt for potentially suspicious activity stemming from uncommon folders.
Potential Suspicious Mofcomp Execution
Detects execution of the "mofcomp" utility as a child of a suspicious shell or script running utility or by having a suspicious path in the commandline. The "mofcomp" utility parses a file containing MOF statements and adds the classes and class instances defined in the file to the WMI repository. Attackers abuse this utility to install malicious MOF scripts
Potential Suspicious PowerShell Keywords
Detects potentially suspicious keywords that could indicate the use of a PowerShell exploitation framework
Potential Suspicious PowerShell Module File Created
Detects the creation of a new PowerShell module in the first folder of the module directory structure "\WindowsPowerShell\Modules\malware\malware.psm1". This is somewhat an uncommon practice as legitimate modules often includes a version folder.
Potential Suspicious Registry File Imported Via Reg.EXE
Detects the import of '.reg' files from suspicious paths using the 'reg.exe' utility
Potential Suspicious Windows Feature Enabled
Detects usage of the built-in PowerShell cmdlet "Enable-WindowsOptionalFeature" used as a Deployment Image Servicing and Management tool. Similar to DISM.exe, this cmdlet is used to enumerate, install, uninstall, configure, and update features and packages in Windows images
Potential Suspicious Windows Feature Enabled - ProcCreation
Detects usage of the built-in PowerShell cmdlet "Enable-WindowsOptionalFeature" used as a Deployment Image Servicing and Management tool. Similar to DISM.exe, this cmdlet is used to enumerate, install, uninstall, configure, and update features and packages in Windows images
