Disclosure context

About Akira

Akira is a ransomware group that emerged in April 2023, operating with primarily financial motivations and has rapidly established itself as a significant threat actor with over 1,500 documented victims. The group's country of origin remains unclear, though they operate as a Ransomware-as-a-Service (RaaS) model, recruiting affiliates to conduct attacks while the core group maintains the ransomware infrastructure and negotiation processes. Akira employs multi-faceted attack methodologies including exploitation of VPN vulnerabilities, particularly targeting Cisco VPN appliances, and utilizes living-off-the-land techniques along with legitimate administrative tools to avoid detection, while implementing double extortion tactics by exfiltrating sensitive data before deploying their encryption payload. The group has demonstrated a preference for targeting organizations in the United States, Canada, Germany, United Kingdom, and Italy, with a particular focus on manufacturing, business services, technology, and construction sectors, though they have shown willingness to attack various industries. Despite being relatively new to the ransomware landscape, Akira has maintained consistent operations throughout 2023 and into 2024, with law enforcement agencies including CISA and FBI issuing advisories about their activities, though no major disruption operations have been publicly reported against the group as of late 2024. The group has been linked to 1,674 public disclosures across our corpus. First observed on a leak site on April 26, 2023; most recent post July 16, 2026. The operation is currently active.

If your organisation is affected

A listing by Akira means Plumley Engineering appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, NCSC (United Kingdom), as required for your jurisdiction.
  • Monitor for the data appearing on Akira's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
