# Incident Report: Lee Enterprises Ransomware Attack by Qilin
## Executive Summary
The Qilin ransomware group claimed responsibility for a cyber incident against US newspaper publisher Lee Enterprises, which occurred on February 3rd. The attack involved encryption of critical applications and exfiltration of approximately 350 GB of sensitive data. The threat actor is demanding a ransom, threatening publication of the data by March 5th, and the incident caused disruptions across at least 75 of the company's publications.
## Incident Details
- Discovery Date: February 3rd (Date of "cyber incident")
- Incident Date: February 3rd
- Affected Organization: Lee Enterprises
- Sector: Media/Publishing
- Geography: USA (Iowa-based publisher with operations across 25 states)
## Timeline of Events
### Initial Access
- Date/Time: Implicitly on or before February 3rd.
- Vector: Not explicitly detailed, but implies a successful intrusion leading to ransomware deployment.
- Details: Attackers gained access to the network environment.
### Lateral Movement
- Details: Not explicitly detailed, but necessary for the attackers to encrypt critical applications across the network.
### Data Exfiltration/Impact
- Date/Time: Occurred between initial access and detection, culminating in the disruption.
- Details: Approximately 350 GB of data was stolen, including investor records, financial arrangements, payments to journalists, and funding for tailored news stories. Critical applications were encrypted, disrupting operations.
### Detection & Response
- Date/Time: February 3rd (when the "cyber incident" was sustained).
- Details: The company acknowledged a "cyber incident" and subsequent encryption/exfiltration, subsequently filing with the SEC. The public claim by Qilin was made after this date.
## Attack Methodology
- Initial Access: Not explicitly detailed.
- Persistence: Not explicitly detailed.
- Privilege Escalation: Not explicitly detailed, but implied to gain access to critical systems.
- Defense Evasion: Not explicitly detailed.
- Credential Access: Not explicitly detailed.
- Discovery: Not explicitly detailed, but necessary to identify high-value data (financial, investor records) and critical systems.
- Lateral Movement: Implied through the encryption of critical applications across many publications.
- Collection: Gathering 350 GB of sensitive data including financial and internal documents.
- Exfiltration: Attempted or successful exfiltration of the 350 GB dataset.
- Impact: Encryption of critical applications shutting down services, and data theft with extortion threat.
## Impact Assessment
- Financial: Implied significant financial impact due to ransom demand and operational disruption.
- Data Breach: Approximately 350 GB of sensitive data, including investor records, financial arrangements, and internal communications related to journalism and funding.
- Operational: Disruption to at least 75 of the publisher's 350+ newspapers.
- Reputational: High potential for reputational damage due to the exposure of sensitive internal dealings and customer/investor data, amplified by the public ransom threat.
## Indicators of Compromise
- Network indicators: [None provided, IPs and domains should be analyzed externally]
- File indicators: [None provided]
- Behavioral indicators: Deployment of ransomware leading to application encryption and mass data staging/exfiltration.
## Response Actions
- Containment measures: Not detailed, but addressing the "cyber incident" implies network segmentation or isolation.
- Eradication steps: In progress, likely involving rebuilding encrypted systems.
- Recovery actions: Working to restore encrypted critical applications.
## Lessons Learned
- Lessons Learned: Reliance on security controls was insufficient to prevent initial access and subsequent ransomware execution on critical systems.
- What could have been done better: Stronger preventative controls against initial access vectors and more robust data backup/disaster recovery architecture to mitigate encryption impact.
## Recommendations
- Prevention measures for similar incidents: Implement rigorous access control (Zero Trust/JIT access), enhance network segmentation to limit lateral movement impact, and test offline backups suitable for rapid recovery from ransomware events.
