MITRE reference S0092
Agent.btz obtains the victim username and saves it to a file.3
Agent.btz creates a file named thumb.dd on all USB flash drives connected to the victim. This file contains information about the infected system and activity logs.4
Agent.btz drops itself onto removable media devices and creates an autorun.inf file with an instruction to run that file. When the device is inserted into another system, it opens autorun.inf and loads the malware.5
Agent.btz attempts to download an encrypted binary from a specified domain.6
Agent.btz saves system information into an XML file that is then XOR-encoded.7
Standing S0092
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.
Reach
Techniques629th pct
29th percentile · 71% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics653rd pct
53rd percentile · 53% of 825 ATT&CK software entries have this many tactics spanned 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.
Campaigns085% tie · 8 values
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
