S1129: Akira
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]

Executive priority
S1129: Akira is an official MITRE ATT&CK software. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate S1129: Akira by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Windows), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
- Network, endpoint, and security-tool telemetry
Detection direction
- Validate whether S1129: Akira appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.
Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.

Groups, software, and campaigns
G1024: Akira
Akira is a ransomware variant and ransomware deployment entity active since at least March 2023.[1] Akira uses compromised credentials to access single-factor external access mechanisms such as VPNs for initial access, then various publicly-available tools and techniques for lateral movement.[1][2] Akira operations are associated with "double extortion" ransomware activity, where data is exfiltrated from victim environments prior to encryption, with threats to publish files if a ransom is not paid. Technical analysis of Akira ransomware indicates variants capable of targeting Windows or VMWare ESXi hypervisors and multiple overlaps with Conti ransomware.[3][4][5]

| 19.1 | 2.0 | Older bundle | 3fe511ae2e0e… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
