Southern
Water takes its data protection and information security
responsibilities to you seriously, and so we are bringing this to your
attention as soon as we can. We are working closely with the regulatory
authorities. We have notified the Information Commissioner’s Office and
are in regular contact with the National Cyber Security Centre. In
addition, we have taken further steps, with support from independent
cybersecurity experts, to enhance the security monitoring of our IT
infrastructure.
We
have also engaged a reputable third party to monitor the dark web on
our behalf. They report that, since we were named on the cyber
criminals’ site on 22 January 2024, they have found no new evidence of
data potentially compromised by this cyber incident being published
online. They will continue to carry out these checks for as long as
necessary.
To
ensure that we’re doing everything we can to look after you, we are
offering you a 12-month, free-of-charge, enhanced Experian credit
monitoring membership. This service provides identity monitoring and
helps detect possible misuse of your personal information. It also
supports identification and resolution of identity theft incidents....
What is the background?
On
22 January 2024 we became aware that a cyber criminal organisation was
claiming on its website to have stolen data from some of our IT systems.
We
had previously detected suspicious activity and launched an
investigation, as well as enhanced monitoring and other precautionary
measures. Our independent cyber security specialists continue to
investigate.
What happens next?
The
information we have provided is based on what we know at this time. Our
investigation remains active, and should we receive any additional
material information, we will contact you.
Once
again, I am very sorry that this has happened and for any inconvenience
this illegal breach of data may cause you. We are working closely with
the authorities and industry experts, to do everything possible to
manage the situation and support you at this time.

FURTHER INFORMATION
The
National Cyber Security Centre, the Financial Conduct Authority and the
Information Commissioners Office all provide helpful information to
help protect your data and prevent fraud. This is summarised below with
some useful links.
-
Stay alert against any suspicious calls, texts or emails which could be
a scam. If you receive any suspicious messages or calls, do not hand over any information such as your bank account details.
Instead, hang up, or delete any worrying texts or emails and then
contact your bank to report the suspicious activity. The FCA has some
useful information on how to spot the warning signs of financial scams
at www.fca.org.uk/consumers/protect-yourself-scams.
- Cyber criminals commonly use a scam technique called “phishing”,
which is mostly email-based but can also be via telephone calls, to
lure victims under false pretences to websites which appear legitimate
to get them to provide information including bank account and credit
card details. These emails/phone calls appear to be from recognisable
sources such as banks but actually link to fraudulent websites. To help
prevent phishing:
- More helpful information on how to protect your data can be found on the National Cyber Security Centre’s website - www.ncsc.gov.uk/guidance/data-breaches and the Information Commissioner’s Office website – www.ico.org.uk/for-the-public/identity-theft and www.ico.org.uk/for-the-public/online."
