What do we know about the Southern Water data breach claim?

Sensitive customer information including full names, dates of birth, National Insurance numbers, bank account details, sort codes, and reference numbers have likely been accessed by cybercriminals in the attack.

Current and former employees of Southern Water may have had their HR documents and identity verification materials compromised, including passports, driving licences, and utility bills stored on company systems.

The cyberattack was executed by the notorious hacker collective Black Basta, a sophisticated criminal organisation that is reported to have successfully extorted over $100 million (circa £75m) in ransom payments since 2022.

Those impacted by the breach are strongly advised to stay vigilant for potential phishing attempts, identity fraud, and suspicious activity, and to report any suspected scams to the relevant authorities immediately.

If you've been impacted by this data breach, you may be entitled to compensation for the violation of your privacy rights.

The Data Breach Advisors has partnered with KP Law Limited who will handle your claim on a no-win, no-fee basis, meaning there's no financial risk to you in pursuing the compensation you deserve.
