# Incident Report: Disputed Akira Ransomware Claim Against Apache OpenOffice
## Executive Summary
The Akira ransomware group publicly claimed to have breached Apache OpenOffice and stolen 23 GB of sensitive corporate data on October 30th. However, the Apache Software Foundation (ASF) strongly disputed this claim, stating they do not possess the types of employee or financial data described, as OpenOffice is an open-source project staffed by unpaid contributors. To date, investigations have found no evidence of compromise to ASF or OpenOffice infrastructure, and no ransom demand has been received.
## Incident Details
- **Discovery Date:** October 30, 2025 (When Akira publicized the claim)
- **Incident Date:** Claimed to have occurred shortly before October 30, 2025
- **Affected Organization:** Apache Software Foundation (ASF) / Apache OpenOffice project
- **Sector:** Software / Open Source Development
- **Geography:** Undisclosed (Global project infrastructure)
## Timeline of Events
### Initial Access
- **Date/Time:** Before October 30, 2025
- **Vector:** Claimed Ransomware Activity (Specific access vector unconfirmed/disputed)
- **Details:** Akira gang listed Apache OpenOffice on their leak site, claiming successful exfiltration of 23 GB of data.
### Lateral Movement
- **Date/Time:** N/A
- **Details:** Not applicable or not confirmed by ASF investigation. Attack details are based solely on threat actor claims.
### Data Exfiltration/Impact
- **Date/Time:** Claimed to have occurred before October 30, 2025
- **Details:** Akira claimed to have stolen 23 GB of documents, including internal confidential files, employee information (SSNs, driver licenses, credit cards), and financial records.
### Detection & Response
- **Date/Time:** On or after October 30, 2025
- **Details:** ASF became aware when the claim was published online. ASF initiated an internal investigation immediately.
## Attack Methodology
- **Initial Access:** Claimed to be ransomware activity.
- **Persistence:** Not detailed/not confirmed.
- **Privilege Escalation:** Not detailed/not confirmed.
- **Defense Evasion:** Not detailed/not confirmed.
- **Credential Access:** Claimed to involve employee PII and financial data access.
- **Discovery:** Claimed to identify internal confidential files.
- **Lateral Movement:** Not detailed/not confirmed.
- **Collection:** Claimed to gather 23 GB of documents.
- **Exfiltration:** Claimed data theft occurred prior to publication.
- **Impact:** Claimed data exposure; ASF investigation suggests impact is unsubstantiated.
## Impact Assessment
- **Financial:** No reported ransom demand made at the time of reporting.
- **Data Breach:** Alleged theft of 23 GB, including PII (SSNs, driver licenses, credit card info) and internal financial files. ASF disputes the existence of this data set within their infrastructure.
- **Operational:** No reported operational disruption to the OpenOffice project or ASF infrastructure.
- **Reputational:** Minor reputational impact due to the public nature of the threat actor's claim.
## Indicators of Compromise
- **Network indicators:** None provided/confirmed.
- **File indicators:** None provided/confirmed.
- **Behavioral indicators:** Public posting on the Akira data leak site on October 30, 2025.
## Response Actions
- **Containment measures:** ASF began an internal investigation immediately upon notification.
- **Eradication steps:** Not applicable; no evidence of compromise found during the initial investigation.
- **Recovery actions:** None required as no compromise was confirmed. ASF confirmed they have not contacted law enforcement or cybersecurity experts related to this claim yet.
## Lessons Learned
- **Key takeaways:** Public claims by ransomware groups targeting open-source projects require immediate, though skeptical, investigation due to potential reputational damage.
- **What could have been done better:** N/A, as the primary response was verification and dispute against an unsubstantiated claim. The transparent nature of OpenOffice development aids in quickly verifying data access claims.
## Recommendations
- **Prevention measures for similar incidents:** ASF should continue to maintain transparent development practices (mailing lists) which act as a natural defense against claims of stolen internal communications. Review standard procedures for responding to data extortion claims targeting components with geographically distributed, non-employee contributors.
