Detects the creation or registration of scheduled tasks that masquerade as Google Chrome updates but point to non-standard executable paths. This is a common technique used by malware to establish persistence by mimicking legitimate software update tasks.
Detects the creation of scheduled tasks that contain the string 'Google Chrome Update' in the command line, but are not associated with the legitimate GoogleUpdate.exe binary. This is a common technique used by malware to establish persistence by masquerading as a legitimate update process.
Detects attempts to inhibit system recovery by deleting volume shadow copies or modifying backup/boot recovery configurations. The rule monitors for the execution of vssadmin, wmic, wbadmin, and bcdedit with flags known to facilitate system recovery inhibition, often observed as a precursor to ransomware activity.
This rule detects unauthorized persistence attempts by monitoring for the creation of a registry value named 'DailyFitnessTracker' under the HKEY_CURRENT_USER Run key. It triggers when 'reg.exe' is used to add the key, PowerShell is used to set the registry property, or when a general registry event indicates the creation of this specific key. This behavior is indicative of a persistence mechanism designed to launch a potentially malicious or unwanted program upon user logon.
Detects execution of cmd.exe originating from potentially malicious or unexpected parent processes associated with RUSTYSHADE malware activity. This rule monitors for cmd.exe invoked by processes like 'DriverInstaller.exe' or 'Automata-20.exe', or processes other than standard Windows system processes (explorer.exe or services.exe), which is indicative of command-line shell abuse for malicious operations.
Detects the execution of a scheduled task named 'MicrosoftEdgeUpdateTaskUserS-1-5-24' which triggers conhost.exe with the --headless argument or PowerShell with an EncodedCommand. This behavior is indicative of a malicious persistence mechanism masquerading as a legitimate Edge update task, specifically associated with the retrieval of payloads from the malicious domain 'indiatodays.org'.
This rule detects the execution of the HTSPnew.Exe ransomware payload, associated with a trojanized HTS DLL, and subsequent ransomware-related file operations, such as the creation of .krsid encrypted files and the dropping of a Korean-language ransom note (README_KRSID.Txt).
Detects the execution of 'HTSPnew.Exe', a utility associated with suspicious activity or ransomware simulation, combined with command-line arguments that suggest testing, batch execution, or help requests.
This rule detects scenarios where a specific parent process generates five or more child processes, which can be an indicator of suspicious automation, scripting activity, or potential brute-force behavior. It groups events by host and parent process image to identify potential anomalous process density.
Detects the execution of common command-line or scripting interpreters (cmd, powershell, cscript, etc.) spawned by the ScreenConnect remote administration client. This is a common pattern used by attackers leveraging legitimate remote access tools for post-exploitation activities and lateral movement.
Detects the execution of processes named 'DriverInstaller.exe' or 'Automata-20.exe', the invocation of cmd.exe as a child process of these executables, or network requests originating from these processes to GitHub API and raw content endpoints. This pattern is indicative of potential initial access, tool staging, or malicious payload retrieval.
Detects modifications to the Windows Registry 'Run' key or execution of commands via reg.exe or PowerShell that attempt to create or modify a persistence entry named 'DailyFitnessTracker'. This technique is commonly used by malware to ensure execution upon user logon.
Detects the execution of LNK files that launch cmd.exe to execute batch script files (e.g., .bat). This pattern is frequently used in malicious infection chains, such as those leveraged by Transparent Tribe (APT36), where ISO or ZIP archives contain LNK files masquerading as document files to trick users into executing malicious scripts.
Detects persistence mechanisms used by a Golang RAT, specifically targeting the creation of a 'DailyFitnessTracker' registry value in the HKCU Run key using reg.exe or PowerShell, and the placement of 'FitnessMonitor.exe' into the Windows Startup folder.
Detects execution of shell commands by cmd.exe in conjunction with the creation or modification of 'command.txt' or 'results.txt' files, which are indicative of the RUSTYSHADE backdoor's C2 synchronization behavior.
Detects execution of APT36's RUSTYSHADE backdoor, typically delivered via a DriverInstaller executable or zip file, and specifically tracks downloads from Backblaze B2 storage buckets using PowerShell.
Detects the establishment of persistence by the RUSTYMOVE malware through the creation of a scheduled task via PowerShell. The rule specifically looks for a command line containing both 'Register-ScheduledTask' and the specific masqueraded name 'StandAloneOneDriveUpdater-2626', which mimics a legitimate OneDrive update process.
Detects the execution of PowerShell commands by the RUSTYMOVE tool intended to enumerate external removable storage devices (USB, SD, MMC, IEEE1394). The rule monitors for the concurrent use of Get-Volume, Get-Partition, and Get-Disk cmdlets with specific BusType filtering patterns.
Detects malicious scheduled task creation using names intended to mimic Microsoft Edge update tasks. The rule identifies suspicious process activity including the spawning of conhost.exe with headless flags, PowerShell commands with encoded arguments, and attempts to fetch external scripts from the known malicious typosquatted domain indiatodays.org, all of which are characteristic of APT36 (Transparent Tribe) activity.
Detects the execution of a process named 'UBP.Exe' located within a 'UBP-Asset' directory at the root of a drive. This behavior is associated with the KRSID ransomware distribution campaign, which impersonates Union Bancaire Privée to lure victims into executing the fraudulent binary.
Detects the historical HPlus HTS fraud infrastructure chain. The rule monitors for the reading of a configuration file named 'config.Ini', followed by an outbound FTP connection (port 21), and the subsequent launch of an executable, which is indicative of a Quasar RAT deployment sequence.
