Detects execution of PowerShell or CMD initiated by the Kimsuky GitPower loader. The rule identifies suspicious command-line artifacts including excessive character padding (leading spaces), extremely long command lines, and the presence of a hardcoded, unique base64 decoding variable ('$VIUSBvejbawf') associated with this specific malware family.
Detects the use of the 'tar' utility with the '--use-compress-program' flag, where the compression program specified is not a standard system compression tool. This pattern is commonly used by attackers to execute arbitrary payloads when tar extracts malicious archives.
Detects the execution or file activity associated with the 'OrionQuests-Setup.exe' installer. This rule monitors both process creation and file system activity to track the presence and usage of this specific installer executable, which may indicate the installation of potentially unauthorized or untrusted software.
Detects the execution of AutoIt3 scripts using mshta.exe as the parent process from suspicious or non-standard directories such as Temp, Downloads, or AppData. This behavior is indicative of an attempt to bypass application execution policies or obfuscate malicious script execution.

This rule monitors endpoint telemetry for known indicators of compromise associated with the Casbaneiro/Ousaban banking trojan. It identifies activity across network connections (IPs and domain patterns), DNS queries for specific C2 domains, and the presence or execution of known malicious file hashes (e.g., PDF lures, HTA, AutoIt scripts, and payload binaries).
This rule detects potential malware delivery by correlating network visits to known malicious domains used for lure distribution with subsequent large file downloads (.zip files >= 100MB) in typical user download or temporary folders within a short time window. This pattern is characteristic of campaigns leveraging social engineering and file-based evasive techniques (such as padding to bypass static analysis) to distribute malicious payloads.
Detects explorer.exe spawning the genuine cmd.exe binary with an explicit /c flag to run either the doxc\doxc.bat script from the 'My Resume.iso' lure chain, or config.bat co-occurring with the Documents_Details/windowSysUpdates decoy artifacts from the Document_Detail.zip lure chain — both used by Transparent Tribe (APT-C-56) to launch CrimsonRAT or the Golang RAT.
Detects explorer.exe spawning the genuine cmd.exe binary with an explicit /c flag to run either the doxc\doxc.bat script from the 'My Resume.iso' lure chain, or config.bat co-occurring with the Documents_Details/windowSysUpdates decoy artifacts from the Document_Detail.zip lure chain — both used by Transparent Tribe (APT-C-56) to launch CrimsonRAT or the Golang RAT.
Detects the execution of a process named 'hzwzucr_widsisa.exe' located within the 'AppData' directory. The rule further specifies that this process must be spawned by a command line initiated from 'C:\ProgramData\doxc' or by 'cmd.exe', indicating potentially suspicious activity common in malware deployment patterns.
Detects the creation of .iso or .zip files on Windows user directories (Desktop/Downloads) or with suspicious filenames potentially associated with phishing delivery methods.
Detects execution of command-line tools (cmd.exe or .bat files) triggered by Windows Explorer, where the process command line or parent command line references a shortcut (.lnk) file or specific naming conventions like 'doxc.bat' or 'config.bat'. This pattern is frequently used in phishing attacks to execute malicious payloads disguised as legitimate files.
Detects known PowerShell dropper and embedded StealC payload binaries used in the ClickFix infection chain via exact SHA256 hash equality only

Detects instances where the Zoom installer process (zoominstaller.exe) initiates potentially suspicious child processes such as cmd.exe, powershell.exe, or scripting hosts (wscript.exe, cscript.exe) that are executing script files within a short timeframe. This behavior is indicative of a potential installer hijack or malicious payload execution attempting to leverage the context of a legitimate software installer.

This behavior is indicative of a potential installer hijack or malicious payload execution attempting to leverage the context of a legitimate software installer.
Detects the execution of 1C:Enterprise business automation software processes (1cv8.exe, 1cv8c.exe, rphost.exe) using specific suspicious external processing files (epf) such as 'Obrabotka_bez_svedeniy.epf' or 'ExternalProcessing1'. This includes detection of the file creation event to identify potential persistence or execution of malicious automation scripts within the 1C environment.
Detects phishing emails associated with the Mirage2FA campaign, which utilize HTML smuggling via .htm, .xhtml, or .svg attachments, often disguised as voicemail or contract-related documents. The rule also accounts for social engineering lures involving QR codes.
Detects MSBuild process execution originating from command shells loading obfuscated scripts or inline projects associated with PavinLoader.
Detects when common torrent client applications spawn a child process that is an executable. This behavior is often associated with the execution of malicious payloads delivered or masqueraded as files within torrent environments.
Detects the execution of suspicious executables spawned from common torrent client applications. This rule monitors for known malicious file hashes or processes launched by torrent clients with suspicious naming patterns typically associated with pirated software or malware masquerading as media files (e.g., tags like 1080p, x264, bluray in executable names).
