Detects mshta.exe being launched from explorer.exe or cmd.exe with a command line argument pointing to a remote HTTP/HTTPS resource ending in .hta. This pattern is commonly used by adversaries to execute malicious remote HTML applications for initial access or code execution.

Detects patterns indicative of automated brute-force attacks against authentication interfaces by counting consecutive remote logon failures for single user accounts. This behavior was observed in the FortiBleed campaign targeting Fortinet devices.
This rule detects exploitation attempts targeting CVE-2026-0300 in Palo Alto Networks PAN-OS. It identifies suspicious network connections to User-ID Authentication Portal ports (6081, 6082) from external IP addresses, excluding RFC1918 and loopback ranges. Additionally, it looks for a specific anomalous User-Agent string associated with the CL-STA-1132 threat actor, which has been observed during exploitation of this vulnerability.

Detects the creation of specific AI assistant configuration files (e.g., Cursor, Claude, Gemini, VS Code) by alternative runtimes. The Miasma malware targets modern AI coding assistants to inject hidden backdoors that trigger automatically when projects are opened.
This rule detects suspicious activities related to AWS S3 buckets that could indicate a bucket hijacking attempt or unauthorized replication to an external account. Specifically, it looks for two scenarios: 1) an S3 bucket being deleted and then recreated by a different AWS account within a one-hour window, suggesting a namespace hijacking, or 2) an S3 bucket being deleted while a PutBucketReplication event references an external AWS account, indicating an attempt to exfiltrate data or maintain access through replication.
This rule detects the execution of PowerShell commands or script blocks that contain specific de-obfuscation patterns associated with the ErrTraffic/ClickFix malware. It looks for the presence of '-bxor' and '[convert]::ToInt32' within PowerShell command lines or script blocks, indicating an attempt to decode obfuscated content.
Detects explorer.exe making DNS requests to Discord or Telegram, which is anomalous and indicates potential process injection for data exfiltration. This behavior is associated with information stealer malware like Phantom Stealer.
This rule detects communication patterns indicative of the ErrTraffic webshell by searching for specific parameters ('wp_debug_session=' and 'mode=php') within web server URI/URL fields. The presence of these parameters suggests an active webshell connection, likely used for remote access and command execution on a compromised web server.
