MITRE reference S1194
Akira _v2 will fail to execute if the targeted /vmfs/volumes/ path does not exist or is not defined.7
The Akira _v2 encryptor targets the /vmfs/volumes/ path by default and can use the rust-crypto 0.2.36 library crate for the encryption processes.89
Akira _v2 can enumerate the trace, debug, error, info, and warning logs on targeted systems.1415
Standing S1194
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.
Tactics541st pct
41st percentile · 59% of 825 ATT&CK software entries have more tactics spanned.
Threat group161% 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.
