Detects abnormal memory allocation patterns and excessive runner operations in Ollama that may indicate resource exhaustion attacks, memory abuse through malicious model loading, or attempts to degrade system performance by overwhelming GPU/CPU resources. Adversaries may deliberately load multiple large models, trigger repeated model initialization cycles, or exploit memory allocation mechanisms to exhaust available system resources, causing denial of service conditions or degrading performance for legitimate users.
Detects changes to payment or bank account information in Workday. This activity is associated with 'payroll pirate' attacks by threat actor Storm-2657, who modify payroll details to divert salary payments after compromising an account.
This rule detects the presence of known Chaos ransomware samples by matching their SHA256 hashes against process execution events and file events. If a process with a matching hash is executed or a file with a matching hash is observed, an alert will be triggered.
Detects the configuration of a new ISATAP router on a Windows host. While ISATAP is a legitimate Microsoft technology for IPv6 transition, unexpected or unauthorized ISATAP router configurations could indicate a potential IPv6 DNS Takeover attack using tools like mitm6.
In such attacks, adversaries advertise themselves as DHCPv6 servers and set malicious ISATAP routers to intercept traffic.
This detection should be correlated with network baselines and known legitimate ISATAP deployments in your environment.

Detects Chaos C++ ransomware payloads based on known file hashes and unique embedded strings from the malware.
This rule detects various activities associated with the InterLock Ransomware (UNC5774). It identifies anti-VM checks performed via PowerShell, specifically looking for commands that query for QEMU, memory less than 4GB or 1.5GB, or specific desktop naming conventions. It also detects local group and Service Principal Name (SPN) enumeration using PowerShell cmdlets like 'Get-LocalGroupMember', 'Get-LocalGroup', or ADSI queries for 'samAccountName' and 'servicePrincipalName'. Persistence mechanisms are covered by monitoring registry Run/RunOnce keys for entries that launch 'node' or 'php' executables. Furthermore, the rule looks for suspicious staging of 'node.exe' or 'php.exe' within the AppData\Roaming directory when initiated by PowerShell processes. The rule leverages 'DeviceProcessEvents', 'DeviceRegistryEvents', and 'DeviceEvents' (specifically PowerShellCommand action type) to capture these activities.
Detects the use of systemctl mask to disable system power management targets such as suspend, hibernate, or hybrid sleep.
Adversaries may mask these targets to prevent a system from entering sleep or shutdown states, ensuring their malicious processes remain active and uninterrupted.
This behavior can be associated with persistence or defense evasion, as it impairs normal system power operations to maintain long-term access or avoid termination of malicious activity.

Detects a high volume of process and service terminations using 'taskkill.exe' and 'sc.exe' within a short time frame. This behavior is characteristic of ransomware like FunkLocker, which aggressively disables applications and services to prepare for encryption.
Detects attempts to exploit multiple vulnerabilities (CVE-2025-52905, CVE-2025-52906, CVE-2025-52907) in TOTOLINK X6000R routers. Attackers can leverage argument injection, unauthenticated command injection, and security bypasses through the '/cgi-bin/cstecgi.cgi' endpoint to achieve remote code execution or denial of service.
Detects PhantomCard, an Android NFC-relay Trojan targeting banking customers in Brazil. It masquerades as a 'card protection' app and relays NFC data from the victim's card to the fraudster's device.
Detects attempts to suspend or terminate Endpoint Detection and Response (EDR) agent processes by targeting their Process IDs (PIDs). The rule identifies suspicious command-line arguments and tools (e.g., procdump, WerFault) used to interact with processes, specifically looking for these actions against a predefined list of common EDR agent executable names. It correlates process creation events with process ID resolution to identify the targeted EDR agent.
Detects a high volume of file rename operations where files are appended with a randomized 16-character hexadecimal extension. This is a characteristic behavior of LockBit 5.0 ransomware during its encryption phase.
This rule detects the Warlock ransomware by identifying specific byte patterns associated with its core functionalities. These patterns include code responsible for encrypting files, killing processes, stopping services, and discovering drives, which are common behaviors of ransomware.
Detects the usage of command-line tools such as 'net', 'sc', 'powershell', 'wmic', or 'psservice' to stop, pause, disable, or delete critical Windows services. This activity is often observed in ransomware attacks and other malicious campaigns aiming to evade defenses or cause impact by targeting security software, backup solutions, and other essential system services.
This rule detects suspicious activities related to Protected Process Light (PPL) and driver loading that could indicate privilege escalation, defense evasion, or impact. Specifically, it looks for:
1. Processes running with 'System' integrity that were initiated by a process with a lower integrity level, which could suggest an attempt to elevate privileges.
2. Driver image load events where 'ntoskrnl.exe' is the initiating process, but the driver is loaded from a location outside of the standard 'System32' or 'System32\drivers' directories. This could indicate an adversary attempting to load malicious drivers to evade detection or persist.
3. DriverLoad actions initiated by 'ntoskrnl.exe' from outside the standard 'System32' or 'System32\drivers' directories, similar to the image load events, pointing to potential malicious driver activity.

This detection identifies a single MAC address rapidly appearing on multiple switch ports within a short time frame. This behavior, known as MAC flapping, is a strong indicator of a network loop, which can cause broadcast storms and degrade or disable network services.
This KQL Query is oriented to extract the different bits of TCP Flags which helps to review the different state of the connections and identify possible threats associated.
In addition, it allows to filter by specific TCP Flag to detect specific threats based on every case.

Yara rule that detects Warlock ransomware.
KQL Query
Detects the execution of multiple commands commonly used by Dire Wolf ransomware to delete backups, shadow copies, and event logs, thereby inhibiting system recovery. The rule triggers when more than one of these anti-recovery commands are executed on the same host within a 10-minute window, distinguishing malicious patterns from isolated, legitimate administrative actions.
Detects the creation of files in a deceptive directory 'C:\Windows \System32\' (with a space after 'Windows'). This technique is used by a Zephyr/XMRig cryptomining campaign to stage files for DLL search order hijacking of 'printui.exe'.
