Akira ransomware, written in C++, is most prominently (but not exclusively) associated with the ransomware-as-a-service entity Akira. Akira ransomware has been used in attacks across North America, Europe, and Australia, with a focus on critical infrastructure sectors including manufacturing, education, and IT services. Akira ransomware employs hybrid encryption and threading to increase the speed and efficiency of encryption and runtime arguments for tailored attacks. Notable variants include Rust-based Megazord for targeting Windows and Akira _v2 for targeting VMware ESXi servers.[1][2][3]

MITRE reference S1129
Akira verifies the deletion of volume shadow copies by checking for the existence of the process ID related to the process created to delete these items.5
Akira will execute PowerShell commands to delete system volume shadow copies.67
Akira executes from the Windows command line and can take various arguments for execution.8
Akira uses the GetSystemInfo Windows function to determine the number of processors on a victim machine.9
Akira examines files prior to encryption to determine if they meet requirements for encryption and can be encrypted by the ransomware. These checks are performed through native Windows functions such as GetFileAttributesW.1011
Standing S1129
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
Techniques1047th pct
47th percentile · 53% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics3Bottom 21%
21st percentile · 79% 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.

85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
