Turn Sigma into a SIEM-ready query.
Paste your own rule or send one directly from the detection index.
Potential Arbitrary File Download Using Office Application
Detects potential arbitrary file download using a Microsoft Office application
Potential Netcat Reverse Shell Execution
Detects execution of netcat with the "-e" or "-c" flags followed by common shells, which are commonly used to spawn reverse shells.
Potential PowerShell Obfuscation Using Alias Cmdlets
Detects Set-Alias or New-Alias cmdlet usage. Which can be use as a mean to obfuscate PowerShell scripts
HackTool - Dumpert Process Dumper Execution
Detects the use of Dumpert process dumper, which dumps the lsass.exe process memory
Elevated System Shell Spawned
Detects when a shell program such as the Windows command prompt or PowerShell is launched with system privileges. Use this rule to hunt for potential suspicious processes.
LSASS Access From Program In Potentially Suspicious Folder
Detects process access to LSASS memory with suspicious access flags and from a potentially suspicious folder
Potential Shellcode Injection
Detects potential shellcode injection as seen used by tools such as Metasploit's migrate and Empire's psinject.
Suspicious Login Activity Classified By Google
Detects Google Workspace login activity that's classified as suspicious by Google.
ServiceDll Hijack
Detects changes to the "ServiceDLL" value related to a service in the registry. This is often used as a method of persistence.
DNS Query to External Service Interaction Domains
Detects DNS queries to well-known out-of-band application security testing (OAST) and callback domains. These services (e.g. Burp Collaborator, interactsh, canarytokens, dnslog.cn) are used by security researchers and attackers alike to confirm blind vulnerabilities such as SSRF, XXE, blind RCE, and Log4Shell-style injections, where the exploit payload triggers an external DNS lookup to a controlled domain. A detection indicates that a host on your network resolved one of these domains, which may mean: (1) an attacker is actively probing or exploiting a vulnerable service and using the callback to confirm code execution or data exfiltration, (2) a security scanner (e.g. Nuclei, Gobies) is running against internal targets. Investigate the source host, the full DNS query string (the unique subdomain prefix encodes the callback session), and any concurrent outbound connections or process activity to determine intent.
