MiniBus is a custom backdoor used for command execution, data discovery, gathering, and exfiltration. MiniBus has utilized Azure Cloud Infrastructure and unique adversary-controlled domains for command and control. MiniBus is an updated platform to its predecessor MiniBike and was first observed in August 2023. MiniBus has been affiliated with the cyber espionage threat group NIMBUS MANTICORE.[1]

Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
MiniBus has created persistence through the use of autostart registry keys to include HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\OneDriveCoUpdate.7
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 842 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
Techniques838th pct
38th percentile · 62% of 842 ATT&CK software entries have more Enterprise techniques.

54th percentile · 54% of 842 ATT&CK software entries have this many tactics spanned or fewer.
Threat group162% tie · 22 values
62% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
