Detectors
Every Cortex detection rule the toolbox knows about — analytics alerts, BIOCs and correlation rules — in one filterable set.
15 detectors match the current filters.
Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| 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 | Abnormal RPC traffic to multiple hosts The endpoint performed unfamiliar RPC activity to multiple hosts. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Reconnaissance |
| Analytics | Abnormal sensitive RPC traffic to multiple hosts The endpoint performed unfamiliar RPC activity to multiple hosts using a known sensitive interface. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Lateral Movement |
| Analytics | Abnormal sensitive RPC traffic to multiple hosts from a rarely seen host The endpoint performed unfamiliar RPC activity to multiple hosts using a known sensitive interface. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent with eXtended Threat Hunting (XTH) | Lateral Movement |
| Analytics | DNS Tunneling 10 KB or more were sent encoded in subdomain names during a 10-minute window. All subdomains queried were under a single suspicious domain. DNS tunneling encodes data in DNS queries and responses, allowing an attacker to bypass firewalls and proxies to reach his or her command and control server, even when HTTP/S traffic is blocked. The endpoint may be remotely controlled by an attacker, and/or an attacker may have exfiltrated data from it. This detector is not supported when networking events arrive solely from Cortex XDR Linux agents. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control, Exfiltration |
| Analytics | Failed DNS The endpoint is performing DNS lookups that are failing at an excessively high rate when compared to its peer group. This alert might be symptomatic of malware that is trying to connect to its command and control (C2) servers. The attacker's C2 server runs on one or more domains that can eventually be identified and blacklisted. To avoid this, malware will sometimes use Domain Generation Algorithms (DGA) that produce many domain names every day. Because only a few of these domains are ever registered, the installed malware must blindly try to access each generated domain name in an effort to locate an active one. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control |
| Analytics | HTTP with suspicious characteristics Uncommon HTTP communication was performed by the host that might indicate its attempt to hide malicious activities. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control, Exfiltration |
| 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 | Multiple Suspicious FTP Login Attempts Multiple suspicious FTP sessions were detected, which may indicate a brute-force attempt. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs | Initial Access, Credential Access |
| Analytics | Random-Looking Domain Names The endpoint performed DNS lookups to an excessively large number of apparently random root domain names. This alert might be symptomatic of malware that is trying to connect to its command and control (C2) servers. The attacker's C2 server runs on one or more domains that can eventually be identified and blacklisted. To avoid this, malware will sometimes use Domain Generation Algorithms (DGA) that produce many unique, random-looking domain names every day. Because only a few of these domains are ever registered, the installed malware must blindly try to access each generated domain name in an effort to locate an active one, which may also trigger the Failed DNS alert. | Medium | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Command and Control |
| 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 | Rare LDAP enumeration Possible LDAP enumeration with a rare combination of queries. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs | Discovery |
| Analytics | Subdomain Fuzzing The root domain within the network is experiencing an unusually high number of access requests to its subdomains, significantly exceeding the typical activity levels for that domain. This anomaly could suggest that someone is attempting to enumerate subdomains or uncover additional virtual hosts associated with the domain, possibly as part of a reconnaissance effort to identify vulnerable or less-secured entry points into the network. | Low | Platform Analytics | Palo Alto Networks Firewall EAL Logs, XDR Agent | Reconnaissance |
| 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 |
