Detects unauthorized access attempts to MinIO object storage using the default 'minioadmin' credentials. The rule specifically flags attempts to access sensitive files like 'terraform-state' or 'credentials.json' via HTTP GET requests.
Detects outbound network traffic originating from internal assets destined for IP addresses identified as Command and Control (C2) infrastructure associated with the UAT-7810 threat actor group.
This rule detects attempts to exploit an unauthenticated administration API vulnerability (CVE-2026-35616) in FortiClient EMS versions 7.4.5 and 7.4.6, commonly referred to as FortiBleed. This vulnerability could allow an unauthenticated attacker to gain unauthorized access to the administration interface.
Detects incoming HTTP POST requests to the /PSEMHUB/hub endpoint on Oracle PeopleSoft servers, which is indicative of exploitation attempts related to the Server-Side Request Forgery (SSRF) vulnerability identified as CVE-2026-35273.
This rule detects suspicious Google OAuth authorization requests directed at accounts.google.com that utilize a local redirect URI (http://localhost) and are missing mandatory security parameters such as code_challenge, state, and login_hint. These characteristics are often associated with OAuth-based phishing or credential theft campaigns where an adversary attempts to intercept authorization codes.
Detects HTTP GET requests to signindat.com for suspected malicious payloads, including executables (.exe) and scripts (.ps1), as well as a decoy PDF document. The rule identifies communication with an external host using generic User-Agent strings, characteristic of the CrySome RAT multi-stage download process.
This rule detects attempts to exploit a Server-Side Request Forgery (SSRF) vulnerability in Oracle PeopleSoft by targeting the '/PSIGW/HttpListeningConnector' endpoint. The detection looks for malicious URI patterns and request bodies containing internal-only network indicators such as loopback addresses (127.0.0.1, localhost), link-local addresses (169.254.169.254), or local file access attempts (file://), which are indicative of SSRF exploitation attempts.
Detects HTTP traffic containing a User-Agent string associated with the NetSupport Manager remote access tool. This activity is indicative of the tool being used for unauthorized remote access or as a C2 channel, often seen in the context of the ClickFix campaign.
Detects the use of the 'diagnose sniffer packet' command on a FortiGate network device, which is indicative of an administrator or attacker performing network traffic capture and analysis directly from the device's management interface.
Detects anomalous, oversized IKEv1 Phase 1 packets targeting Check Point VPN devices, indicative of an exploitation attempt for CVE-2026-50751.
Detects high-frequency DNS queries for long, random-looking subdomains that result in NXDomain responses, a behavioral indicator of malware using Domain Generation Algorithms (DGA) for command-and-control beaconing.
Detects a specific network handshake pattern indicative of the Cavern Manticore malware establishing a SOCKS5-over-WebSocket tunnel. The rule monitors for a WebSocket upgrade request followed by the initial SOCKS5 connection authentication byte sequence.
Detects outbound HTTP POST requests to a /gallery URI endpoint, which is associated with Cavern Manticore C2 beacons. The detection logic inspects the HTTP request body for a specific Base64-encoded pattern following XOR 0x48 encoding, indicating potential command-and-control communication.
Detects attempts to exploit Microsoft Exchange vulnerabilities (CVE-2021-34473, CVE-2021-34523, CVE-2021-31207), collectively known as ProxyShell. The rule monitors inbound HTTP requests targeting the /autodiscover/ endpoint with specific path traversal patterns and malicious components used to stage web shells or execute arbitrary commands.
Detects an unusually large data transfer (greater than 5MB) from an internal MySQL server to an external network, which may indicate unauthorized database record exfiltration or data dumping.
Detects outbound network communication to an IP address (64.20.53.230) identified as a staging server associated with the JadePuffer activity. This activity involves potential data exfiltration following self-narrated deletion payloads.
Detects incoming HTTP POST requests to the /PSEMHUB/hub endpoint on Oracle PeopleSoft servers, which is indicative of exploitation attempts related to the Server-Side Request Forgery (SSRF) vulnerability identified as CVE-2026-35273.
Detects anomalous, oversized IKEv1 Phase 1 packets targeting Check Point VPN devices, indicative of an exploitation attempt for CVE-2026-50751.
Detects attempts to exploit the Log4Shell vulnerability (CVE-2021-44228) by identifying JNDI lookup strings (e.g., ${jndi:ldap://, ${jndi:rmi://, ${jndi:dns://) within HTTP request headers, a technique used to trigger remote code execution in vulnerable Java applications using the Log4j library.
This rule detects outgoing TCP traffic that initiates a SOCKS5 handshake (indicated by the byte sequence |05 01 00|) on destination ports other than standard web ports (80, 443, 8080, 8443). This behavior is characteristic of TOR client traffic attempting to establish an anonymous connection to an external TOR relay or node via non-standard network ports.
This rule detects attempts to exploit a Server-Side Request Forgery (SSRF) vulnerability in Oracle PeopleSoft by targeting the '/PSIGW/HttpListeningConnector' endpoint. The detection looks for malicious URI patterns and request bodies containing internal-only network indicators such as loopback addresses (127.0.0.1, localhost), link-local addresses (169.254.169.254), or local file access attempts (file://), which are indicative of SSRF exploitation attempts.
