Detectors
Every Cortex detection rule the toolbox knows about — analytics alerts, BIOCs and correlation rules — in one filterable set.
17 detectors match the current filters.
Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| Analytics BIOC | A user accessed an uncommon AppID A user accessed an uncommon AppID that is rarely accessed by them or anyone else in the organization. | Informational | Identity Threat Detection (ITDR) | Palo Alto Networks Firewall EAL Logs, Palo Alto Networks Firewall threat Logs, Palo Alto Networks Firewall traffic Logs, XDR Agent | Exfiltration |
| Analytics | A user accessed multiple time-consuming websites A user was observed visiting multiple domains for personal reasons. Time theft happens when an employee is paid to work but did not actually work during that time. It might affect your business as it reduces the employee's efficiency. | Informational | Identity Threat Detection (ITDR), SaaS Threat Detection | Palo Alto Networks Firewall EAL Logs, Palo Alto Networks Firewall threat Logs, Palo Alto Networks Firewall EAL Logs, XDR Agent | Reconnaissance |
| Analytics BIOC | Abnormal network communication with a rare combination of HTTP User Agent and HTTP Server Abnormal network communication with a rare combination of HTTP User Agent and HTTP Server to an external address. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control, Exfiltration |
| Analytics BIOC | Failed Login For a Long Username With Special Characters A long username containing special characters failed to log in to the domain. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Initial Access |
| Analytics | Increase in Job-Related Site Visits A user has visited multiple job-related sites in the past day. | Informational | Identity Threat Detection (ITDR), SaaS Threat Detection | Palo Alto Networks Firewall EAL Logs, Palo Alto Networks Firewall threat Logs, Palo Alto Networks Firewall EAL Logs, XDR Agent | Reconnaissance |
| Analytics | Massive upload to a rare storage or mail domain A large amount of data was transferred to an external site that is used for mail or storage. This behavior may indicate data exfiltration. | Informational | Identity Threat Detection (ITDR), SaaS Threat Detection | Palo Alto Networks Firewall EAL Logs, Palo Alto Networks Firewall threat Logs, XDR Agent | Exfiltration |
| Analytics | Rare access to known advertising domains The endpoint performed many connections to unpopular advertising domains. This could indicate the presence of adware on the endpoint. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control, Persistence |
| Analytics BIOC | Rare DCOM RPC activity The endpoint performed abnormal DCOM RPC activity to a remote host. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Lateral Movement |
| Analytics BIOC | Rare MS-Update Server was detected The endpoint requested an MS-Update operation from a rare update server. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs | Initial Access |
| Analytics BIOC | Rare MS-Update traffic over HTTP The endpoint requested an MS-Update operation with abnormal HTTP traffic characteristics. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Lateral Movement |
| Analytics BIOC | Rare NTLM Usage by User Rare authentication by user account to host via NTLM. The user has not authenticated with NTLM in the past 30 days. This may be indicative of downgrade attacks from Kerberos to NTLM. | Informational | Identity Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Lateral Movement |
| Analytics BIOC | Rare Remote Service (SVCCTL) RPC activity The endpoint performed abnormal RPC activity via Service Control Manager interface to a remote host. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Lateral Movement |
| Analytics BIOC | Rare Scheduled Task RPC activity The endpoint performed abnormal Scheduled Task RPC activity to a remote host. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Lateral Movement, Persistence |
| Analytics BIOC | Suspicious NTLM authentication with machine account A suspicious NTLM authentication attempt was made by a machine account. | Informational | Identity Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Credential Access |
| Analytics | Uncommon WPAD queries There were multiple attempts to access WPAD resources by a single host in your network. This may indicate a malicious activity. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Credential Access |
| Analytics BIOC | Unique client computer model was detected via MS-Update protocol A unique client computer model was detected via MS-Update protocol. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs | Initial Access |
| Analytics BIOC | Weakly-Encrypted Kerberos TGT Response A weakly encrypted Kerberos TGT was issued by a domain controller. The encryption type is abnormal for this DC and results in a TGT that is easier to crack. This behavior may indicate a Skeleton Key attack. | Informational | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Credential Access, Defense Evasion, Persistence |
