Officials said they were forced to conduct fuel sales manually in light of the attack, which took down all of the digital systems used to facilitate payments.
Analysis Summary
# Incident Report: Ransomware Attack on Costa Rican Energy Provider
## Executive Summary
The state-owned energy provider for Costa Rica, RECOPE, suffered a ransomware attack that forced the company to revert to manual operations for fuel distribution and payment processing. The incident, discovered mid-week, led to extended operating hours and required assistance from cybersecurity experts deployed by the U.S. to gradually restore systems. While operations were heavily impacted, RECOPE maintained that fuel supply inventories remained sufficient.
## Incident Details
- Discovery Date: Wednesday morning (specific date not provided, but occurred "last week")
- Incident Date: On or just before Wednesday morning
- Affected Organization: Refinadora Costarricense de Petróleo (RECOPE)
- Sector: Energy/Fossil Fuel Importing, Refining, and Distribution
- Geography: Costa Rica
## Timeline of Events
### Initial Access
- Date/Time: Unknown, breach occurred prior to Wednesday morning discovery.
- Vector: Ransomware (Specific initial access vector not detailed in the summary).
- Details: Discovered ransomware incident on Wednesday morning, immediately disrupting digital systems.
### Lateral Movement
- *Not explicitly detailed in the provided text.*
### Data Exfiltration/Impact
- Details: All digital systems used to facilitate payments were taken down, forcing manual operations for fuel sales at terminals.
### Detection & Response
- Date/Time: Wednesday morning (Discovery).
- Details: Investigation began immediately. Officials moved to conduct fuel sales manually. Operations at tanker terminals were extended late Wednesday and expanded on Thursday.
- Response Actions: RECOPE collaborated with the Ministry of Science, Innovation, Technology and Telecommunications (MICITT). U.S. cybersecurity experts arrived on Thanksgiving to assist with system restoration.
## Attack Methodology
- Initial Access: Ransomware deployment (Specific initial vector unknown).
- Persistence: *Not detailed.*
- Privilege Escalation: *Not detailed.*
- Defense Evasion: *Not detailed.*
- Credential Access: *Not detailed.*
- Discovery: *Not detailed (Attacker reconnaissance).*
- Lateral Movement: *Not detailed.*
- Collection: *Not detailed.*
- Exfiltration: *Not detailed (If data was exfiltrated prior to ransomware deployment).*
- Impact: Disruption of digital payment systems leading to forced manual operations across fuel distribution infrastructure.
## Impact Assessment
- Financial: *Not explicitly detailed (Costs related to restoration and manual operations unknown).*
- Data Breach: *Not specified if data was exfiltrated; digital systems for payments were disabled.*
- Operational: Significant operational disruption requiring the shift to manual processing for fuel sales and extended hours at terminals throughout the week.
- Reputational: Required public communications to assure the population of sufficient fuel inventories amidst growing concerns and increased sales volume due to public worry.
## Indicators of Compromise
- *No specific technical indicators (IPs, domains, hashes) were provided in the text.*
Behavioral: Disruption of core digital systems related to payment and distribution.
## Response Actions
- Containment: Systems were shut down to limit damage (implied by the need for manual operations).
- Eradication: Working with MICITT and U.S. cybersecurity experts to address the threat.
- Recovery: Gradual system restoration began after U.S. experts arrived on Thanksgiving. RECOPE committed to operating manually until safety is fully guaranteed.
## Lessons Learned
- Critical reliance on digital systems for critical national infrastructure (fuel distribution and payments) creates a significant single point of failure during cyber incidents.
- Importance of established international partnerships (e.g., with the U.S.) for rapid deployment of specialized cybersecurity support following major attacks.
- Need for robust contingency and manual operational procedures to maintain essential services during severe IT outages.
## Recommendations
- Implement multi-factor authentication across all enterprise and operational technology (OT) systems.
- Develop and regularly test comprehensive, isolated backups that are segmented from the primary network.
- Enhance network segmentation between IT and OT environments to limit the spread of ransomware from business systems to critical control systems.
- Increase investment in proactive threat hunting and monitoring capabilities, especially following national-level attacks on peer organizations.
