Detects HTTP connections between internal hosts and suspected C2 infrastructure associated with the Operation SilkParasite campaign. The rule specifically monitors for connections to known malicious IPs and identifies the retrieval of a cloned RTX Corporation homepage content, which acts as a decoy for the SpiceRAT malware.
Detects the execution of an ONVIF-related tool or process with flags indicating credential retrieval. This is often associated with the reconnaissance or credential access phase targeting IoT devices such as cameras that support the Open Network Video Interface Forum (ONVIF) protocol.
Detects the creation or use of known backdoor accounts ('p2pwn', 'p2password') on Dahua surveillance devices, which are often utilized by adversaries to maintain unauthorized access to compromised hardware.
Detects incoming emails containing specific file extensions (.r01, .js) or subject lines/attachments related to a known supply chain lure campaign, where authentication protocols (SPF/DMARC) have failed. This combination of indicators is indicative of LausivLoader malspam delivery.
Detects suspicious process creation patterns indicative of process hollowing. The rule identifies processes spawned by common script interpreters (powershell.exe, wscript.exe, cscript.exe, conhost.exe) in a suspended state, followed by memory operations involving ntdll.dll and APIs such as NtUnmapViewOfSection or ResumeThread, which are characteristic of hollowing injection techniques.
Detects execution of LausivLoader by identifying suspicious process creation patterns typically associated with process hollowing. This includes a parent process (powershell.exe or conhost.exe) launching a child process in a suspended state (CREATE_SUSPENDED), followed by behavioral indicators of memory manipulation and code replacement.
Detects execution of PowerShell scripts attempting to modify Windows Defender settings by adding directory exclusions (including the C:\ drive) via cmdlets like Add-MpPreference, Set-MpPreference, or WMI/CIM methods, often followed by a forced Group Policy refresh. This pattern is associated with malicious staging activity, including malware loaders like LausivLoader.
Detects network communication to identified SpiceRAT Command and Control (C2) infrastructure over TCP port 443. This includes monitoring for standard TCP connections and TLS sessions to known malicious IP addresses.
Detects network communication associated with the SilkParasite campaign, specifically identifying TLS traffic using fraudulent certificates impersonating the Uzbekistan railway authority (azure.uzrailwaystax.com) and connections to identified malicious infrastructure using specific JA4X TLS fingerprinting.
Detects HTTP POST requests to the Telegram Bot API (/sendPhoto) containing patterns indicative of data exfiltration. The rule identifies suspicious message content, such as URLs leading to VK.com or reconnaissance data like Shodan host links and IP location query templates, suggesting the use of Telegram as a Command and Control (C2) channel for exfiltrating sensitive information.
