Southern Water, a leading water utility company in the South East of England, has announced<\/a> a significant data breach, potentially impacting between 235,000 and 470,000 of its customers. The breach, which occurred<\/a> in January, saw hackers accessing sensitive customer information during a cyberattack.<\/p>\n

The company, serving millions across the region, disclosed that \u201c5 to 10 percent\u201d of its customer base might have had their personal data compromised. This estimate, based on ongoing forensic investigations, leaves room for the possibility that the number of affected individuals could rise.<\/p>\n

Details of the stolen data, as reported<\/a> by BBC News, include customers\u2019 dates of birth, national insurance numbers, bank account details, and reference numbers. Southern Water has yet to confirm the specifics of the compromised information.<\/p>\n

In addition to customer data, Southern Water revealed plans to inform all current and some former employees about the breach. The utility firm, employing around 6,000 individuals, is still investigating the full extent of the incident.<\/p>\n

The cyberattack was claimed by the Black Basta ransomware<\/a> group, known for its links to Russia and previous attacks on major organizations like the U.K. outsourcing giant Capita. Shortly after the attack, Black Basta listed Southern Water on its dark web leak site, threatening to release 750 gigabytes of sensitive corporate and customer data unless a ransom was paid. The leak site\u2019s listing included screenshots of stolen documents, such as employee passports and identity cards.<\/p>\n

As of now, Southern Water\u2019s name has been removed from Black Basta\u2019s website, a move often seen after victim companies comply with ransom demands. However, Southern Water has not disclosed whether it paid any ransom.<\/p>\n

According to TechCrunch<\/a>, in response to the breach, Southern Water stated it is collaborating with cybersecurity experts to monitor the dark web for any signs of the stolen data being published. So far, the company reports no evidence of the compromised data appearing online.<\/p>\n

The incident has been reported to the U.K.\u2019s Information Commissioner\u2019s Office, as Southern Water continues to assess the breach\u2019s impact and work on bolstering its cybersecurity measures to prevent future attacks.<\/p>\n
