Type Name Severity Module Data source / event ATT&CK
Analytics BIOC Unusual ADFS Remote Synchronization network connections from non-ADFS server Detected an unauthorized configuration sync request to the ADFS Policy Store from a non-ADFS server, step for forging SAML tokens in a Golden SAML attack. Low Platform Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Credential Access, Lateral Movement
Analytics BIOC Unusual AWS credentials creation AWS utility was used to create an access key and a secret key. Low Platform Analytics XDR Agent Persistence
Analytics BIOC Unusual AWS user added to group AWS user added to AWS group, possibly to elevate privileges and gain more access to resources. Low Platform Analytics XDR Agent Persistence
Analytics BIOC Unusual Azure AD sync module load A process that does not usually load the Azure AD Sync mcrypt.dll loaded the module. Low Identity Threat Detection (ITDR) XDR Agent Credential Access
Analytics BIOC Unusual cloud Instance Metadata Service (IMDS) access A request to cloud Instance Metadata Service (IMDS) was made by an unusual process. This process does not usually access the Instance Metadata Service. An attacker may extract cloud compute tokens to gain access to a cloud environment. Informational Cortex Cloud XDR Agent Credential Access
Analytics BIOC Unusual compressed file password protection An adversary might compress sensitive files with password protection to bypass security mitigations when attempting to exfiltrate them. Low Platform Analytics XDR Agent Collection
Analytics BIOC Unusual DB process spawning a shell A DB related process abnormally spawned a shell. This might indicate an exploitation attempt. Informational Platform Analytics XDR Agent Initial Access, Lateral Movement
Analytics BIOC Unusual internal access to network device management interface Unusual internal access to Palo Alto Networks device on management port. Informational Platform Analytics XDR Agent Lateral Movement, Discovery
Analytics BIOC Unusual Kubernetes dashboard communication from a pod The Kubernetes dashboard was accessed by an unusual pod within the environment. Low Platform Analytics XDR Agent Discovery
Analytics BIOC Unusual Lolbins Process Spawned by InstallUtil.exe An unusual process was spawned by InstallUtil.exe, possibly indicating malicious local or remote code execution. Low Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Unusual process accessed the PowerShell history file An abnormal process accessed the PowerShell console history file. This may be a sign of malicious PowerShell execution without directly invoking the powershell.exe binary. Informational Platform Analytics XDR Agent Execution
Analytics BIOC Unusual process executed by AWS Systems Manager An unusual process was executed by the AWS Systems Manager agent. Adversaries may use the Systems Manager agent to execute malicious commands on an endpoint. Medium Cortex Cloud XDR Agent Execution
Analytics BIOC Unusual Process Spawned by Nginx in Ingress-Nginx pod Unusual Process Spawned by Nginx in Ingress-Nginx pod. Low Platform Analytics XDR Agent Execution, Initial Access
Analytics Unusual SSH Activity Unusual SSH activity was detected that involved a higher than usual volume of data transfer and an abnormally long session. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Command and Control
Analytics BIOC Unusual SSH activity that resembles SSH proxy A host initiated and received an unusual SSH connection, which is consistent with being an SSH proxy. This behavior may indicate an attempt to establish covert command and control communication or to exfiltrate data. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Command and Control
Analytics BIOC Unusual weak authentication by user A user account authenticated to a host via NTLMv1 or LM authentication for the first time in the past 30 days. This may be indicative of an NTLM downgrade attack A downgrade attack may force the client to authenticate with a weaker hash/protocol (such as NTLMv1 or even LM) instead of NTLMv2. Informational Identity Analytics XDR Agent Lateral Movement
Analytics Upload pattern that resembles Peer to Peer traffic A possible P2P protocol was spotted from an internal host. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Command and Control, Initial Access
Analytics BIOC VM Detection attempt on Linux A Process executed a command and/or accessed a file that can be used to detect VM environments. Informational Platform Analytics XDR Agent Defense Evasion, Discovery
Analytics BIOC Wbadmin deleted files in quiet mode Wbadmin was used to delete files in quiet mode. High Platform Analytics XDR Agent Impact
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
Analytics BIOC Weakly-Encrypted Kerberos Ticket Requested A user specifically requested weak and deprecated encryption in a Kerberos TGS request. This provides easy-to-crack hashes and is typically a sign of a Kerberoasting attack. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Credential Access
Analytics BIOC Web server CGO executed an uncommon process An uncommon process was executed by a web server CGO, which might indicate a Webshell activity or a web server exploit. Informational Platform Analytics XDR Agent Initial Access, Persistence
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
Analytics BIOC Windows CGO, actor and action processes with anomalous characteristics Windows CGO, actor and action processes with anomalous characteristics. Informational Platform Analytics XDR Agent Execution
Analytics BIOC Windows CGO, actor process and action module with anomalous characteristics Windows CGO, actor process and action module with anomalous characteristics. Informational Platform Analytics XDR Agent Execution
Analytics BIOC Windows Event Log was cleared using wevtutil.exe A command-line utility was used to clear the Windows Event Log. It may be used to delete logs to cover the tracks of the malicious activity, making it harder to perform analysis. Low Platform Analytics XDR Agent Impact
Analytics BIOC Windows Installer exploitation for local privilege escalation The Windows installer (msiexec.exe) was likely exploited to run a malicious rollback script (.rbs file) instead of the original. Users should not be able to modify config.msi during the installation process, only SYSTEM should have access to it. Medium Platform Analytics XDR Agent Privilege Escalation
Analytics BIOC Windows LOLBIN executable connected to a rare external host Scripts connecting to external IP addresses may be sanctioned IT scripts. However, when those external IP addresses are only receiving connections from a few specific endpoints in the organization, these scripts may be an indicator of more suspicious activity. Security testers and adversaries use offensive frameworks that employ forms of scripting which result in this type of network activity. Medium Platform Analytics XDR Agent Command and Control
Analytics BIOC WmiPrvSe.exe Rare Child Command Line A remote WMI command executed a binary proxy, the Windows Management Instrumentation (WMI) Provider Host wmiprvse.exe, which executed a rare child command line. Executing a rare child process can be an indication of remote code execution abuse by an attacker. Low Platform Analytics XDR Agent Lateral Movement, Execution
Analytics BIOC Wscript/Cscript loads .NET DLLs An unusual script loads .NET DLLs, possibly indicating JScriptToDotnet execution. Low Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Wsmprovhost.exe Rare Child Process The PowerShell host wsmprovhost.exe is a proxy process executed remotely through PowerShell when using Windows Remote Management (WinRM). It has executed a rare child process, which may indicate remote code execution abuse by an attacker. Low Platform Analytics XDR Agent Lateral Movement, Execution
