The SciSec team has also made some progress in updating our older detections to match our current schema and documentation. You can see this in the the Updated Legacy Alert section which is below the new alerts.

These alerts have the same power as before but now integrate better with our other Devo products. If you use the MITRE Attack Advisor App, or like to edit your alerts in Loxcope, these detections can now seamlessly integrate with those products. They have also been updated to work better with our SecOps enrichments like the SecOpsAlertDescription lookup, and can now accurately show the MITRE tactics and techniques associated with the alerts.

Try them out, and let us know what you think! . As always, all feedback is welcome and helps us to improve our content. For our next release, we will continue to update these alerts with the goal to complete the migration and use Q1 to assess the validity of all our alerts. Stay tuned!
