We are one of the largest water and wastewater companies in the South East of England and thrive on the passion and hard work of more than 2,000 employees. Together we supply 532 million litres of drinking water every day to more than two million customers and treat and recycle 717 million litres of wastewater for more than four million customers in Kent, Sussex, Hampshire and the Isle of Wight. Water is essential to every aspect of our lives and we're proud to be at the heart of managing water and wastewater services. We drink it, cook with it and use it to clean. Our water supply faces big challenges - the population of the South East is growing fast, and climate change is bringing greater risk of droughts and more extreme weather. It’s a future of more people needing water and wastewater services, with less water to go around. So, together with our customers and communities, we aim to provide a sustainable, high-quality water and wastewater service that helps us create a resilient future for water in the South East.

Southern WaterCyber Attack85412/2025NA
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: Ransomware Tabletop Exercise Tests Water Utility’s Cyber Resilience at Infosecurity Europe At this year’s *Infosecurity Europe* conference, cybersecurity vendor Semperis hosted *Operation 999*, a high-stakes ransomware tabletop simulation targeting a fictional UK water utility, Springfieldshire Water Treatment. The exercise pitted a red team of attackers against a blue team of defenders comprising CISOs, security leaders, and incident response experts to test real-world response strategies in a critical infrastructure scenario. ### The Attack Unfolds The red team launched their assault on December 24, exploiting the utility’s outdated SCADA-based industrial control systems, which were integrated with its IT network. Timing the attack for maximum disruption when staff were on holiday and the head engineer was celebrating a birthday the attackers escalated privileges, encrypted sensitive data, and exfiltrated corporate emails. Their goal: a £20 million ransom, with no intent to sabotage operations (avoiding terrorist-like consequences). When the blue team detected suspicious encryption activity, they followed protocol, notifying the UK’s National Cyber Security Centre (NCSC) and regulators a move prompted by legal warnings about potential fines or liability. External incident response specialists were brought in, while the utility’s leadership faced public backlash, including a press conference by the local council demanding action. ### Extortion Tactics and Financial Exploitation After the blue team refused to pay the ransom backed by authorities and crisis experts the attackers pivoted, leaking customer records online to pressure the utility. Despite the denial, the red team still profited by shorting Springfieldshire Water Treatment’s stock ahead of the attack, exploiting a pending takeover bid by a rival utility. ### Key Takeaways from the Simulation 1. Critical Infrastructure Vulnerabilities – The exercise highlighted the risks of IT-OT convergence, where outdated SCADA systems create entry points for attackers. 2. Stakeholder Coordination – The blue team’s response involved rapid communication with regulators, legal teams, and external experts, though assumptions about reaching stakeholders during a holiday proved optimistic. 3. Financial Motives Over Disruption – Unlike nation-state actors, ransomware groups prioritize profit, using extortion and market manipulation (e.g., stock shorting) rather than physical sabotage. 4. Public and Media Fallout – The attack triggered social media panic and misinformation, underscoring the need for controlled crisis communications. ### Broader Industry Context The scenario mirrored real-world threats: a Semperis survey found that 62% of UK/US utilities were targeted in the past year, with 54% suffering permanent system damage. Meanwhile, Mikko Hypponen of WithSecure noted in a keynote that ransomware presents a more persistent risk than natural disasters, with attackers relentlessly probing defenses. Led by Steve Hill (former Credit Suisse CISO) and featuring security leaders from bp and Schillings Partners, the exercise demonstrated how tabletop simulations akin to military war games can sharpen incident response plans, even if they can’t replicate the chaos of a live attack. The blue team ultimately focused on containment, resilience, and long-term mitigation, reinforcing the need for updated playbooks and cross-team collaboration in critical sectors.

Attack with significant impact with customers data leaks

Description: British supplier of liquid of life, Southern Water botched its internal Sharepoint. They had set up Sharepoint to host customer information as a “your account” style section of their website which exposed URLs that tweaked to view other people’s account information. A vulnerability in this management area allowed any logged-in customer to view bills and documents from other customers, as well as retrieve authentication tokens which allowed for direct API access to their internal billing SharePoint site. Compromised data included customer’s full name, address, customer account number, payment reference number, bill, and payment dates, account balance, payment amount, bill amount, meter details, and meter readings.

Latest Global CVEs (Not Company-Specific)

Description

The WP Go Maps (formerly WP Google Maps) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the processBackgroundAction() function in all versions up to, and including, 10.0.04. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify global map engine settings.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Description

The Save as PDF Plugin by PDFCrowd plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘options’ parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. NOTE: Successful exploitation of this vulnerability requires that the PDFCrowd API key is blank (also known as "demo mode", which is the default configuration when the plugin is installed) or known.

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Description

The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to arbitrary file uploads due to incorrect file type validation in the action_import_module() function in all versions up to, and including, 7.8.9.2. This makes it possible for authenticated attackers, with a lower-privileged role (e.g., Subscriber-level access and above), to upload arbitrary files on the affected site's server which may make remote code execution possible. Successful exploitation requires an admin to grant Hustle module permissions (or module edit access) to the low-privileged user so they can access the Hustle admin page and obtain the required nonce.

The Meta-box GalleryMeta plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping.
