| Analytics | A user connected a new USB storage device to multiple hosts A user connected a new USB storage device to multiple endpoints. | Low | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection, Exfiltration |
| Analytics BIOC | A user connected a USB storage device for the first time A user connected a USB storage device for the first time in the past 30 days. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection, Exfiltration |
| Analytics BIOC | A user created an abnormal password-protected archive A user created an abnormal password-protected archive using an archive program. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | A user performed suspiciously massive file activity A user generated massive file activity by size or distinct file count. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | A user took numerous screenshots A user took numerous screenshots. A valuable organization's information may have been collected in this way. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics BIOC | An unusual archive file creation by a user An archive file was created by a user who doesn't usually create such files. This might indicate an attempt to stage data before exfiltration. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics BIOC | Gmail routing settings changed Gmail routing settings were modified. | Informational | Identity Threat Detection (ITDR), SaaS Threat Detection | Google Workspace Audit Logs | Collection |
| Analytics BIOC | Mailbox Client Access Setting (CAS) changed An attacker may use PowerShell to change the Client Access Settings (CAS) for a mailbox, hence gaining access to the data. | Medium | Platform Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | Massive file activity abnormal to process A user generated massive file activity by size or distinct file count. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | Massive file compression by user Multiple archive files were created by a user. This might indicate an attempt to stage data before exfiltration. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | Massive upload to SaaS service A user uploaded a large amount of data to an organizational cloud storage. This behavior may indicate that the data is being exfiltrated or staged. | Informational | Identity Threat Detection (ITDR), SaaS Threat Detection | Box Audit Log, DropBox, Google Workspace Audit Logs, Office 365 Audit | Exfiltration, Collection |
| Analytics BIOC | OneDrive folder creation A folder was created in OneDrive using Microsoft Graph API. | Informational | Cortex Cloud | Azure Audit Log, Microsoft Graph Logs | Collection |
| Analytics | Outlook files accessed by an unsigned process An attacker may use an uncommon and unsigned process to access Outlook data files. | Low | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| Analytics | Possible data exfiltration over a USB storage device A process generated massive file creation, renaming and write activity to a USB storage device. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection, Exfiltration |
| Analytics | Possible internal data exfiltration over a USB storage device A user generated abnormal massive file activity to a connected USB storage device. | Informational | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection, Exfiltration |
| BIOC | PowerShell script executed from a temporary directory An attacker may try to avoid detection by executing a PowerShell script from a temporary directory. | Informational | Platform Analytics | Process execution | Collection |
| Analytics BIOC | PowerShell used to export mailbox contents An attacker may use PowerShell to export the contents of a mailbox as part of the data staging before exfiltration. | Medium | Platform Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| BIOC | Scripting engine creates a compressed file under a suspicious folder Attackers may compress data before exfiltrating it to reduce network bandwidth consumption; if a compressed file is placed in a suspicious folder, it may be due to malicious activity. | Informational | Platform Analytics | File | Collection |
| Analytics | User collected remote shared files in an archive Multiple files from remote shares were archived in a local file. This may indicate collection of data and staging before exfiltration. | Low | Identity Threat Detection (ITDR) | XDR Agent with eXtended Threat Hunting (XTH) | Collection |
| BIOC | Wscript / Cscript executed from a temporary directory An attacker may try to avoid detection by executing wscript/cscript scripts from a temporary directory. | Informational | Platform Analytics | Process execution | Collection |
