Reach is how much of ATT&CK this malware touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.

The following analytic detects the execution of a batch command designed to recursively delete files or directories, a technique often used by ransomware like Reddot to delete files in the recycle bin and prevent recovery. (...)
The following analytic detects the execution of the sdelete.exe application, a Sysinternals tool often used by adversaries to securely delete files and remove forensic evidence from a targeted host. (...)
This detection identifies the deletion of files within the AutomaticDestinations folder, located under a user’s AppData\Roaming\Microsoft\Windows\Recent directory. (...)
This detection identifies the deletion of RDP bitmap cache files—specifically .bmc and .bin files—typically stored in the user profile under the Terminal Server Client\Cache directory. (...)
This detection identifies the deletion of registry keys under HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Servers\, which store records of previously connected remote systems via Remote Desktop Protocol (RDP). (...)
