LemonDuck is an actively updated and robust malware primarily known for its botnet and cryptocurrency mining objectives. First discovered in 2019, LemonDuck has since adopted more sophisticated behavior and escalated its operations in 2021.

This query calculates device uptime based on periodic DeviceInfo which is recorded every 15 minutes regardless of device's network connectivity and uploaded once device gets online. If its interval is over 16 minutes, we can consider device is turned off.Calculated uptime may include up to 30 minutes gap. Devices may be turned on up to 15 minutes earlier than the "timestamp", and may be turned off up to 15 minutes later than the "LastTimestamp". When the single independent DeviceInfo without any sequential DeviceInfo within 16 minutes before or after is recorded, "DurationAtLeast" will be displayed as "00.00:00:00".
This query looks for file download events identified by Microsoft Defender for Cloud Apps. It will require an corresponding app connector in Microsoft Defender for Cloud Apps.
