Detects potential DLL sideloading of 'iviewers.dll' (OLE/COM Object Interface Viewer) when it is loaded from a location other than the legitimate Windows Kits directories. This technique can be used for persistence, defense evasion, and privilege escalation.
Detects potential DLL sideloading of "SolidPDFCreator.dll" when loaded by an executable other than "SolidPDFCreator.exe" or from an unexpected directory. This technique can be used by adversaries for persistence, defense evasion, and privilege escalation.
Detects potential DLL sideloading of 'wwlib.dll' by identifying instances where 'wwlib.dll' is loaded by an executable that is NOT a legitimate Microsoft Office Word process. This rule specifically filters out loads from standard Microsoft Office installation paths for 'winword.exe' to reduce false positives.
This rule detects when the 'notepad.exe' process initiates a network connection. This behavior is highly unusual for Notepad and can indicate malicious activity such as process injection where a beacon or other malicious code is running within the legitimate Notepad process to establish command and control. Notepad typically only initiates network communication when printing documents, which is filtered out by this rule.
This rule detects attempts by a process to access the memory of 'svchost.exe' with a specific access right ('0x143a'), which is indicative of a credential dumping attempt. The rule filters out legitimate access from 'services.exe' and 'msiexec.exe' to reduce false positives.
Detects the execution of the VMware Xfer utility (VMwareXferlogs.exe) from a directory other than its default installation path. This behavior is indicative of an attempt to sideload arbitrary DLLs, often used by adversaries for privilege escalation, persistence, or defense evasion. The rule specifically looks for instances where 'VMwareXferlogs.exe' is executed from a location not starting with 'C:\Program Files\VMware\'.
Detects the modification of an existing service's configuration (binpath or failure command) using 'sc.exe' or 'reg.exe' to execute an arbitrary payload. This is a common method for establishing persistence or escalating privileges by ensuring a malicious executable runs when the service starts or fails.
Detects suspicious DACL modifications to allow access to a service from a suspicious trustee using 'sc.exe sdset'. This technique can be used by adversaries for privilege escalation or persistence by overriding existing access restrictions on Windows services.
Detects the creation of a scheduled task using the "-XML" flag with a file that does not have the '.xml' extension. This behavior is suspicious because it attempts to masquerade the XML configuration file, potentially as a defense evasion technique during persistence establishment. Adversaries might use this to hide their scheduled tasks from casual inspection.
This rule detects when a user is added to the local Administrators group on a Windows system. It specifically looks for command-line executions of 'net.exe' with 'localgroup <groupname> /add' or 'powershell.exe' with 'Add-LocalGroupMember -Group <groupname>', where the group name contains 'administrators' or 'administrateur'. This activity is often associated with privilege escalation or persistence techniques by adversaries.
