# Incident Report: MathWorks Ransomware Attack Leading to Service Outage
## Executive Summary
MathWorks, the developer of MATLAB and Simulink software, experienced a significant ransomware attack that began on Sunday, May 18th. This incident severely disrupted their IT systems, leading to the outage of essential customer-facing services such as the cloud center, file exchange, and license center. Response efforts included notifying federal law enforcement and gradually restoring critical functionalities, such as Multi-Factor Authentication (MFA) and Single Sign-On (SSO) by May 21st.
## Incident Details
- **Discovery Date:** Sunday, May 18 (when services began becoming unavailable)
- **Incident Date:** Commenced Sunday, May 18
- **Affected Organization:** MathWorks
- **Sector:** Software Development/Mathematical Computing
- **Geography:** Headquartered in Natick, Massachusetts, with global operations.
## Timeline of Events
### Initial Access
- **Date/Time:** Sunday, May 18
- **Vector:** Ransomware attack (specific initial vector not disclosed)
- **Details:** Attack affected IT systems, causing online applications and internal systems to become unavailable.
### Lateral Movement
- Details regarding specific lateral movement techniques are not provided in the source material. The focus is on the impact to services.
### Data Exfiltration/Impact
- **Impact:** Outage of mandatory online services including cloud center, file exchange, license center, and MathWorks store. Internal staff systems were also affected. Some users continue to experience login issues as of the report timeframe.
### Detection & Response
- **Detection:** Manifested publicly as service unavailability starting May 18th.
- **Response Actions:** Notified federal law enforcement. Began restoration of services; MFA and SSO were restored by May 21st.
## Attack Methodology
- **Initial Access:** Ransomware (Mechanism unspecified)
- **Persistence:** Not disclosed.
- **Privilege Escalation:** Not disclosed.
- **Defense Evasion:** Not disclosed.
- **Credential Access:** Not disclosed.
- **Discovery:** Not disclosed.
- **Lateral Movement:** Not disclosed.
- **Collection:** Not disclosed.
- **Exfiltration:** The article notes that the attacker's intent included data theft, but whether exfiltration occurred or what data was targeted is unknown.
- **Impact:** Denial of Service via encryption/disruption, leading to operational outages.
## Impact Assessment
- **Financial:** Not disclosed.
- **Data Breach:** Unknown if customer data was exfiltrated. The primary immediate impact was on service availability.
- **Operational:** Significant disruption to online applications (cloud, licensing, sales) used by over 100,000 organizations and 5 million customers. Issues persisted for some users regarding account creation and login past May 21st.
- **Reputational:** Public acknowledgment of a ransomware attack impacting core services.
## Indicators of Compromise
- **Network indicators:** None explicitly listed in the summary.
- **File indicators:** None explicitly listed in the summary.
- **Behavioral indicators:** Service unavailability, failure of authentication systems (MFA/SSO affected).
## Response Actions
- **Containment:** Implied actions taken to stop the spread of ransomware and isolate affected systems.
- **Eradication:** Not detailed, but efforts were underway to clean and restore impacted infrastructure.
- **Recovery:** Gradual restoration of services; MFA and SSO restored May 21st.
## Lessons Learned
- **Key Takeaways:** A single ransomware event can severely disrupt critical software vendors whose services integrate deeply into customer operations (licensing, cloud access).
- **What could have been done better:** The source material does not provide an internal review, but the extended ongoing login issues suggest recovery/failover processes for core authentication services may need hardening.
## Recommendations
- Implement robust, segmented backups for all critical IT and authentication infrastructure, ensuring offline copies are tested regularly.
- Enhance network segmentation to limit the scope of potential ransomware infection spread once initial access is achieved.
- Accelerate the deployment and hardening of multi-factor authentication and Single Sign-On (SSO) across all services, particularly those critical to customer access.
- Prepare detailed, pre-approved communication templates for law enforcement notification and customer updates in the event of a confirmed ransomware incident.
