Industrial technology company Colt has confirmed that a recent ransomware attack on its business support systems resulted in the theft of customer data, marking the latest in a series of high-profile cybersecurity incidents affecting critical infrastructure providers.
The company disclosed that threat actors successfully accessed files containing customer-related information, prompting immediate containment measures and ongoing forensic investigations.
Incident Details and Initial Response
The cyberattack targeted Colt’s business support systems, which the company emphasized are completely separate from customer infrastructure environments.
Upon detecting the intrusion, Colt’s security team immediately implemented containment protocols and took affected systems offline to prevent further compromise.
The company has confirmed that authentication systems remain isolated between business and customer environments, limiting the potential scope of the breach.
Colt’s incident response strategy involved deploying both internal teams and external cybersecurity specialists to conduct comprehensive forensic analysis.
The company has maintained continuous 24/7 investigation efforts since the incident’s discovery, working closely with law enforcement agencies and regulatory authorities.
This collaborative approach demonstrates adherence to standard incident response protocols for critical infrastructure providers.
While Colt has confirmed that customer data was accessed by the attackers, the company is still conducting detailed analysis to determine the exact nature and scope of compromised information.
The ongoing investigation aims to identify which specific customer files were accessed and what types of data they contained. This assessment phase is critical for determining notification requirements under data protection regulations such as GDPR.
The company has proactively engaged specialist third-party investigation and forensic support teams to ensure thorough analysis of the incident.
These external experts are working alongside Colt’s internal security personnel to trace the attack vectors and assess the full extent of the compromise.
As part of its containment strategy, Colt proactively took several customer-facing systems offline, resulting in significant service disruptions.
Affected services include the Colt Online customer portal, Number Hosting APIs, and the Colt On Demand Network-as-a-Service portal.
New service ordering and delivery capabilities have also been suspended during the investigation period.
The company acknowledged that automated customer support processes have been disabled as a precautionary measure, leading to extended response times for customer inquiries and service requests.
These disruptions highlight the operational challenges organizations face when balancing security containment with business continuity requirements.
Moving forward, Colt has implemented additional containment and security hardening measures designed to prevent similar incidents.
The company continues working with regulators and law enforcement while conducting its comprehensive investigation to ensure full remediation of the security vulnerabilities that enabled this attack.
