Attackers used previously leaked username and password pairs to gain unauthorized access to user accounts. Once inside, they scraped sensitive genetic data from user profiles. The breach primarily affected users in the UK and Germany, exposing 20 million genetic data profiles. This attack highlighted the dangers of password reuse and emphasized the need for robust authentication mechanisms like multi-factor authentication (MFA).
Impact
The breach of genetic data raises severe privacy concerns and potential misuse, impacting user trust and the company’s reputation.
4. Indian Council of Medical Research (ICMR) Breach
Overview
One of India’s largest breaches in 2023 involved the ICMR’s COVID-testing database, significantly impacting the country’s healthcare sector.
Technical Details
Threat actors exfiltrated personal data of 815 million residents from the ICMR’s COVID-testing database. The compromised data included names, addresses, passport numbers, and Aadhaar numbers. This breach likely resulted from vulnerabilities in the database’s security controls, emphasizing the need for stringent data protection measures in healthcare systems.
Impact
The breach posed significant risks for identity theft and fraud, with sensitive personal information being sold on the dark web.
5. UK Electoral Commission Breach
Overview
The UK Electoral Commission revealed a cyberattack that compromised the personal information of 40 million voters, raising concerns about electoral integrity and data security.
Technical Details
The breach involved an unpatched Microsoft Exchange server, which attackers exploited to infiltrate the network and steal data. The attack compromised personal information of 40 million voters, including names, addresses, and voting histories. The incident highlighted the importance of maintaining up-to-date security patches and conducting regular security audits.
Impact
The breach raised concerns about the security of electoral systems and the potential for misuse of voter information, leading to increased scrutiny and calls for stronger security measures.
6. Police Service of Northern Ireland (PSNI) Breach
Overview
An insider breach at PSNI exposed sensitive data, highlighting the risks of insider threats and the need for strict data handling protocols.
Technical Details
An employee accidentally posted sensitive data on a public website, including names and ranks of 10,000 officers and staff. Despite being removed quickly, the information was accessed and disseminated by Irish republican dissidents. This breach emphasized the importance of strict data handling protocols and monitoring to prevent insider threats.
Impact
The breach posed significant risks to the safety and security of the affected officers and staff, leading to heightened concerns and increased security measures within the organization.
7. MGM Resorts Cyberattack
Overview
MGM Resorts International was targeted by the BlackCat ransomware group, resulting in significant disruptions and financial losses.
Technical Details
Attackers used social engineering techniques to gain initial access, then exploited vulnerabilities in the IT infrastructure to deploy ransomware. They encrypted over 100 ESXi hypervisors, disrupting the main website, online reservations, and in-casino services. The attack highlighted the persistent threat of ransomware and the need for comprehensive incident response plans.
Impact
The attack caused major operational disruptions, financial losses, and reputational damage, prompting a reevaluation of the company’s cybersecurity measures.
8. DISH Network Ransomware Attack
Overview
DISH Network experienced a substantial outage due to a ransomware attack from the Black Basta gang, demonstrating the critical impact of ransomware on business operations.

How Pen Testing Can Protect Businesses
Penetration Testing (Pen Testing) is a proactive approach to identifying and addressing security vulnerabilities before they can be exploited by malicious actors. Here’s how pen testing can help protect businesses from such breaches:
- Identifying Vulnerabilities: Pen testers simulate real-world attacks to uncover vulnerabilities in systems, applications, and networks. This helps organizations identify and remediate weaknesses before they can be exploited.
- Improving Security Posture: Regular pen testing ensures that security measures are effective and up-to-date. It helps organizations maintain a robust security posture by continuously evaluating and enhancing their defenses.
- Enhancing Incident Response: Pen testing helps organizations develop and refine their incident response plans by identifying potential attack vectors and response scenarios. This ensures a swift and effective response in the event of a breach.
- Compliance and Assurance: Many regulatory frameworks and industry standards require regular pen testing to ensure compliance. Conducting pen tests demonstrates an organization’s commitment to security and helps meet regulatory requirements.
- Raising Awareness: Pen testing provides valuable insights into the latest attack techniques and trends. This information helps organizations educate their staff about potential threats and promote a culture of security awareness.
