Missing - Indicates the canary file has been deleted or renamed. If a canary is in this state, an investigation has been triggered and incident reports will be generated if we find signs of ransomware activity. Modified - Indicates the canary file has been modified but retains the same file name as its original state. Monitored - Indicates the canary file has successfully been placed and the file is being monitored for ransomware activity. This is typical when a Huntress agent is initially deployed. Pending - Indicates the canary file has been queued to be placed on the Host and will be added the next time the Agent checks in. Individual canary files will be in one of 4 states: To view information on the ransomware canaries for a machine, log into the Huntress Dashboard, select the Agent, and click "Monitored Files" on the left side. Tripped - Indicates a canary file that is in either the "Modified" or "Missing" state (see below.) The Huntress Threat Ops team will investigate the canaries in this state, and incident reports will be generated if we find signs of ransomware activity. Pending - Indicates the canary file has been queued to be placed on the Host and will be added the next time the Agent checks in. When viewing the agent details (see below), these states match to a variety of individual canary file states.Īrmed - Indicates the number of canaries that have been successfully deployed in your environment and are being monitored. In this view, you can see three states of a canary file: Armed, Pending, and Tripped. To see the summary of all ransomware canary data for your account, click on the bird in the cage in the left-hand menu bar to see the dashboard view for your account's canaries. There are two places in the Huntress Portal, where you can find canary information, the Dashboard, and the "Monitored Files" view at the Agent level. Viewing Ransomware Canaries from the Huntress Portal Ransomware Canaries must be enabled by a user who is an Administrator on the account. Canaries must also be enabled from the Account level, if a user attempts to enable Canaries from the Organization home page they will receive a message to contact the Account Administrator. To enable Ransomware Canaries, click the "birdcage" icon from the left side of the home page and click "Enable" This is not the normal behavior of an actual ransomware event and may have delayed reporting (or no report at all). Note on testing Ransomware Canaries: Partners often try to change the contents of a single canary file or delete it entirely.

It also allows Host Isolation if enabled. It also allows for the easy identification of endpoints that were affected in a ransomware outbreak, assisting our partners in discovering the scope of an attack. This warning capability allows for early alerting, leading to a faster response, and ideally better containment of an incident. NOTE: The ransomware canaries feature is part of a detection and alert platform and does not prevent ransomware from detonating or spreading by itself, our Managed Host Isolation feature must be on for automatic action to take place to stop the spread). Our team will review the conditions causing the alert in order to confirm ransomware and sending an incident report with incident details. When the Huntress Agent detects that a canary file has been altered, renamed, or deleted (such as by ransomware encryption), it will alert our Threat Operations Team. Similar to how miners used canaries in coal mines to detect carbon monoxide, this feature deploys canary files in various directories and monitors them for changes. The Huntress "Ransomware Canaries" service is designed to detect ransomware activity on an endpoint. Please see Updates to Canaries (and below) for details! Updates include new file types PDF and XLSX, system profile canaries, EFS visibility, the ability to add your own logo/support URL, and the ability to disable canaries. We've recently released an updated version of Ransomware Canaries that we're calling Canaries V2.
