Analysis Summary
# Incident Report: Baker University Data Breach (December 2024)
## Executive Summary
Baker University experienced a significant data security event in December 2024, characterized by suspicious activity that led to a network outage starting around December 2nd. Investigations confirmed unauthorized access and acquisition of files between December 2nd and December 19th, 2024, potentially compromising sensitive personal data of affiliated individuals. The university responded by securing its environment, launching an investigation, notifying affected parties, and implementing additional security measures.
## Incident Details
- Discovery Date: December 2024 (Date specific detection not provided, only the start of suspicious activity)
- Incident Date: December 2, 2024 (Start of unauthorized access/acquisition) through December 19, 2024 (End of confirmed unauthorized activity).
- Affected Organization: Baker University
- Sector: Education
- Geography: Kansas, USA
## Timeline of Events
### Initial Access
- Date/Time: On or before December 2, 2024
- Vector: Undisclosed (Suspicious activity discovered)
- Details: Unauthorized access initiated, leading to discovery of suspicious activity.
### Lateral Movement
- Date/Time: Between December 2, 2024, and December 19, 2024
- Vector: Internal network traversing (Implied by unauthorized access/acquisition of "certain files and folders within Baker’s network")
- Details: Attackers maintained access long enough to conduct unauthorized acquisition of data.
### Data Exfiltration/Impact
- Date/Time: Between December 2, 2024, and December 19, 2024
- Impact: Unauthorized *acquisition* of certain files and folders occurred. Personally Identifiable Information (PII) potentially compromised includes Name, Date of Birth, Driver’s License Number, Financial Account Information, Health Insurance Information, Medical Information, Passport Information, Social Security Number (SSN), Student ID Number, and Tax Identification Number.
- **Note:** Baker University reported having no evidence of actual or attempted identity theft or fraud resulting from the breach, as of the press release date.
### Detection & Response
- Date/Time: In December 2024 (Discovery)
- Detection Method: Discovery of "suspicious activity related to certain systems."
- Response Actions: Immediate steps taken to secure the environment, launch of an investigation, review of compromised files, notification to affected individuals, and notification to state and federal regulators.
## Attack Methodology
*Note: Specific TTPs are not detailed in the source material; the following is inferred based on the impact description.*
- Initial Access: Undisclosed.
- Persistence: Implied through the 17-day window of unauthorized access (Dec 2 - Dec 19).
- Privilege Escalation: Not specified, but required to access a breadth of sensitive data categories.
- Defense Evasion: Not specified.
- Credential Access: Likely utilized stolen credentials to facilitate data acquisition.
- Discovery: Required to locate and categorize "certain files and folders."
- Lateral Movement: Required to reach systems containing the sensitive PII.
- Collection: Gathering of diverse PII categories (SSN, financial, health, passport details).
- Exfiltration: Implied by the term "acquisition," though the method is unknown.
- Impact: Data theft/unauthorized access leading to system instability (network outage).
## Impact Assessment
- Financial: Undisclosed (No mention of ransom payment, but potential litigation costs inferred from pending lawsuits).
- Data Breach: High potential for PII exposure, including financial data, SSNs, medical information, and passport details for individuals affiliated with the university.
- Operational: Experienced a temporary **network outage** due to the suspicious activity requiring immediate securing steps.
- Reputational: Public disclosure required; potential for class-action lawsuits filed by law firms.
## Indicators of Compromise
- **Insufficient Data in Source:** Specific IOCs (IP addresses, file hashes, domains) were not available in the provided text.
## Response Actions
- **Containment:** Took "immediate steps to secure its environment."
- **Eradication:** Implied through securing the environment and launching an investigation, though explicit eradication steps are not detailed.
- **Recovery:** Not detailed, other than the general effort to review security policies and implement additional protective measures moving forward.
- **Notification:** Direct notification to affected individuals and notification to state and federal regulators. Complimentary credit monitoring services offered to impacted individuals.
## Lessons Learned
- **Dwell Time:** The unauthorized access spanned 17 days (Dec 2 to Dec 19), indicating potential gaps in real-time monitoring or insufficient detection capabilities for initial intrusion activities.
- **Data Sensitivity:** The diverse and highly sensitive nature of the compromised data highlights a key risk associated with storing large volumes of regulated PII (SSN, medical, financial data).
- **Communication Timing:** The incident occurred in December 2024, but the press release was issued 'this week' (around December 23, 2025), suggesting a delayed public notification relative to the initial event discovery or confirmation of scope.
## Recommendations
- Enhance network monitoring and logging specifically targeting unusual data access patterns or credential usage to reduce attacker dwell time.
- Review and segment sensitive data repositories; ensure the principle of least privilege is rigorously applied to minimize the breadth of data accessible by internal systems or compromised accounts.
- Conduct a comprehensive review of incident response communication procedures to ensure timely and transparent disclosure when incidents are confirmed.
