Detects the use of appcmd.exe to disable HTTP logging for an IIS site by setting 'dontLog' to True. Adversaries may perform this action to evade detection and prevent security logging of their activities on a compromised web server.
Detects instances where common browser processes (e.g., Chrome, Edge, Firefox) spawn command-line tools or scripting interpreters such as PowerShell, cmd, mshta, or rundll32. This pattern is characteristic of 'ClickFix' social engineering attacks where users are tricked into executing malicious commands under the guise of troubleshooting or CAPTCHA resolution.
This rule detects techniques commonly used by attackers to dump credentials from the Local Security Authority Subsystem Service (LSASS) process. It monitors for the execution of known Mimikatz binaries or the use of specific Mimikatz command-line arguments, the execution of legitimate tools like Procdump to dump LSASS memory, the misuse of rundll32 with comsvcs.dll to perform a memory dump, and the creation of files named lsass.dmp, which are common artifacts of credential dumping activities.
Detects potential exploitation of 7-Zip RAR5 vulnerabilities where the Mark-of-the-Web (MOTW) Zone.Identifier is not propagated during extraction, enabling files to execute without SmartScreen warnings. The rule monitors for the creation of executable file types in common user-writable directories by 7-Zip processes and the subsequent execution of files from those locations by explorer.exe.
Detects the use of native Windows commands 'net.exe' and 'net1.exe' to perform domain group or user enumeration, as well as the execution of 'ADExplorer.exe' (a known tool for viewing and editing Active Directory objects). These activities are commonly associated with the reconnaissance phase of an attack to map network infrastructure and identify privileged accounts.
Detects the execution of common Windows system utilities (tasklist.exe, sc.exe, reg.exe, wmic.exe, powershell.exe) with command-line arguments indicative of security software, antivirus product, or system service enumeration. This activity is frequently associated with reconnaissance efforts by threat actors attempting to identify defensive capabilities.
Detects artifacts and activity related to the exploitation of CVE-2026-55200 in libssh2. The rule monitors for the creation or execution of identified libpwn exploit harness files and scripts, as well as suspicious network activity involving TCP port 2222, which is the default port for the PoC rogue SSH server. It also correlates the appearance of these exploit files with subsequent outbound SSH connections.
Detects execution of Mimikatz or usage of common tools like Procdump to dump LSASS memory. The rule monitors for characteristic command-line arguments, renamed binary names associated with Mimikatz, and the extraction of sensitive credentials to output files.
This rule detects potential command and control (C2) activity associated with a known npm RAT, identified by network connections to specific C2 infrastructure (95.216.92.207:8080) or DNS resolution of 'nvidiadriver.net'. The rule specifically flags these events when performed by common execution tools like 'python.exe' or 'chost.exe', or when the process image is running from a temporary directory, which is a common persistence or execution indicator for malware.
Detects attempts to perform container escapes by abusing the 'docker cp' command. The rule identifies path traversal sequences in 'docker cp' arguments, as well as unauthorized shell or script execution spawned by container daemon processes (e.g., dockerd, containerd) following a file copy operation, and specific file creation patterns indicative of a container escape attempt.
This rule detects suspicious activity on Linux systems including unauthorized modification of SSH authorized_keys, creation of unauthorized system accounts (e.g., 'troot'), manipulation of critical system files like /etc/passwd or /etc/shadow, and the execution of specific suspicious scripts or commands indicative of an exploit or post-exploitation activity.
Detects ClickFix attack patterns where users are coerced into pasting malicious PowerShell commands into the Windows Run dialog (explorer.exe). The command uses clipboard access (Get-Clipboard) or network download/execution (iwr, iex) methods, commonly associated with the Potemkin Loader or RMM-based distribution campaigns.
This rule detects file creation and process execution events associated with specific SHA256 hashes linked to the APT28 threat actor exploiting CVE-2026-21509.
This rule detects file creation and process execution events associated with specific SHA256 hashes linked to the APT28 threat actor exploiting CVE-2026-21509.
This rule detects the creation or configuration of a scheduled task named 'GoogleErrorReport' which references 'Fondue.exe' located in the 'C:\Users\Public' directory. This specific pattern is associated with 'Dropping Elephant' malware persistence, where the task ensures the binary executes persistently on the host.
Detects execution of the Microsoft Connection Manager Profile Installer (cmstp.exe) when initialized with an INF file from potentially suspicious directories (e.g., Temp, AppData), or when cmstp.exe is observed spawning common command-line shells (cmd.exe, powershell.exe) or rundll32.exe, which is indicative of potential proxy execution or UAC bypass techniques.
Detects malicious activity associated with the exploitation of StreamBucket PHP vulnerabilities. The rule monitors for unexpected child processes spawned by PHP/web server processes, the creation of specific exploitation artifact files in /tmp, unauthorized reading of /proc/self memory files by PHP, and inbound SOAP-related HTTP requests.
Detects suspicious activities originating from OpenVPN Connect processes, including the spawning of command-line interfaces, scripts, or proxies, as well as the creation of specific ACE marker files and modifications to browser proxy settings, which are indicative of potential exploitation or post-exploitation activity.
Detects instances where the RustDesk application process launches suspicious child processes (e.g., cmd.exe, powershell.exe, wscript.exe) that are not associated with legitimate administrative functions (like installation or service management). This pattern indicates potential exploitation of RustDesk session permission bypass vulnerabilities to execute arbitrary commands on a remote system.
Detects reconnaissance and post-exploitation activity associated with the exploitation of the libssh2 CVE-2026-55200 vulnerability. The rule identifies the execution of known libpwn PoC binaries, libssh2-dependent client applications (curl, git, php) spawning unexpected shell processes, and unauthorized access to SSH-related configuration or key files by non-interactive processes.
Detects the initialization phase of the Operation DragonReturn DcRAT loader, specifically identifying the creation of a unique named global mutex (Global\ShitSetupOn26126k) which acts as a single-instance enforcement mechanism and is often associated with sandbox evasion techniques.
