Type Name Severity Module Data source / event ATT&CK
Analytics BIOC A compressed file was exfiltrated over SSH Exfiltration of a compressed file over SSH. Informational Platform Analytics XDR Agent Exfiltration
Analytics BIOC A process connected to a rare cloud resource A process connected to a rare cloud resource. Informational Platform Analytics XDR Agent Command and Control, Exfiltration
Analytics BIOC A Torrent client was detected on a host The host produced traffic consistent with the BitTorrent protocol. Torrent usage may expose the organization to malware or enable attackers or malicious insiders to exfiltrate data. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Exfiltration, Initial Access
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 BIOC Abnormal communication with a rare combination of TLS and HTTP User Agent Abnormal communication with a rare combination of TLS and HTTP User Agent to an external address. Low Platform Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Command and Control, Exfiltration
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 Commonly abused AutoIT script connects to an external domain AutoIT scripts have legitimate uses, but are often abused by malware to execute in a signed process context. Medium Platform Analytics XDR Agent Exfiltration, Execution
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 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 Large Upload (FTP) The endpoint transferred an excessively large amounts of data to a single destination over FTP. Cortex XDR Analytics assumes endpoint traffic towards a specific destination should be about the same over long periods of time. For that reason, Cortex XDR detected this abnormal behavior of a large data upload. An attacker may be exfiltrating data directly to the internet using this protocol. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Exfiltration
Analytics Large Upload (Generic) The endpoint transferred large amounts of data to an external site using a different protocol from HTTP/s, FTP, or SMTP. (A specific detector is used for each of those protocols.) Cortex XDR Analytics assumes that data transfers out of your network are ordinarily performed using one of those three services, so it expects that data transfers over all other ports to be low. For the same reason, Cortex XDR Analytics also assumes endpoint traffic towards a specific destination should be about the same over long periods of time. An attacker may be exfiltrating data directly to the internet. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Exfiltration
Analytics Large Upload (HTTPS) The endpoint transferred an excessive amount of data to an external site over HTTPS. The destination is not a popular upload site for endpoints on your network, and the endpoint performing the upload has not previously downloaded a large amount of data from the site. The upload is considered excessive based on comparison to baseline measurements of HTTPS data transfers on your network. An attacker may be exfiltrating data directly to the internet. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Exfiltration
Analytics Large Upload (SMTP) The endpoint, which is not an internal SMTP server, emailed an excessive amount of data from your network. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Exfiltration
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 BIOC Possible IPFS traffic was detected The host attempted to access other nodes in an IPFS manner. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Exfiltration, Initial Access
Analytics BIOC Possible use of IPFS was detected The host produced traffic consistent with IPFS. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Exfiltration, Initial Access
Analytics BIOC Python HTTP server started Python HTTP server started - possible exfiltration over HTTP. Informational Platform Analytics XDR Agent Exfiltration
Analytics BIOC Rare SMTP/S Session The Simple Mail Transfer Protocol (SMTP) and its SSL-secured variant SMTPS are used to send email. Attackers can use SMTP/S to exfiltrate data from your network. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Exfiltration
Analytics BIOC Rare Unix process divided files by size A file was divided into sub-files by size limit by a rare process. Informational Platform Analytics XDR Agent Exfiltration
Analytics Suspicious DNS traffic 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. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Command and Control, Exfiltration
Analytics BIOC Suspicious Network Connection Originating from AWS SSM Agent A process spawned by the AWS SSM agent connected to an anonymous tunnel or TOR IP outside AWS. This may indicate the SSM agent was abused for command and control or data exfiltration. Medium Cortex Cloud XDR Agent Command and Control, Exfiltration
Analytics BIOC Uncommon AppleScript was executed via the command line to contact an external server The AppleScript interpreter executed a script designed to contact an external server. Low Platform Analytics XDR Agent Execution, Exfiltration
Analytics BIOC Uncommon recurring rare external host access A process has established recurring connections to an uncommon external host. Informational Platform Analytics XDR Agent Command and Control, Exfiltration
Analytics BIOC WebDAV drive mounted from net.exe over HTTPS Attackers may mount a WebDAV drive over HTTPS to upload files to and download files from a compromised machine. Informational Platform Analytics XDR Agent Exfiltration
