MITRE reference S0438
Attor has opened the registry and performed query searches.3
Attor has a file uploader plugin that automatically exfiltrates the collected data and log files to the C2 server.4
Strings in Attor's components are encrypted with a XOR cipher, using a hardcoded key and the configuration data, log files and plugins are encrypted using a hybrid encryption scheme of Blowfish-OFB combined with RSA.5
Attor's dispatcher disguises itself as a legitimate task (i.e., the task name and description appear legitimate).6
Attor's dispatcher can establish persistence via adding a Registry key with a logon script HKEY_CURRENT_USER\Environment "UserInitMprLogonScript" .7
Standing S0438
Reach is how much of ATT&CK this tool 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.

96th percentile · 96% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.

Threat groups061% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
