The article describes a significant data breach affecting South Staffordshire Water and its parent company, South Staffordshire PLC, which resulted in the compromise of personal information on over 633,000 individuals. The breach was traced back to a phishing attack in September 2020 that installed malware, which went undetected for nearly two years before being discovered in July 2022 due to IT performance issues. The threat actor stole 4.1TB of highly sensitive data including personal details, HR information, and customer account data. The Information Commissioner’s Office (ICO) fined the company £1m ($1.4m), which was 40% lower than the initial proposed fine of £1.6m to avoid contesting the penalty. The incident highlighted multiple security failings, including inadequate monitoring, the use of outdated software, and weak vulnerability management practices. The ICO emphasized the necessity for critical infrastructure companies to enforce proactive security measures and established protocols to protect sensitive data.
