Suno AI Music Generator Data Leak
A data leak at the AI music generator Suno, which occurred in November 2025, became public in July 2026. The breach exposed data from over 55 million unique email addresses and, for users who registered with their phone numbers, those numbers as well. A small portion of the dataset also included payment processor Stripe data, leading to the leak of names, physical addresses, purchase amounts, and certain credit card details (card type, expiration date, and last four digits) for tens of thousands of users. Suno confirmed it does not have access to full credit card numbers via Stripe.

The municipality of IJsselstein removed several documents from its website on July 27, 2026, after a resident discovered that they contained personal data. These documents were found within the municipal council's information system, which violates privacy legislation. The municipality has reported the incident to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) and is reviewing all published meeting documents dating back to January 1, 2014. While affected individuals will be informed, the specific types of data exposed have not been disclosed. Locoburgemeester Peter Bekker emphasized the need to restore trust in the handling of personal data and prevent future occurrences. An investigation into the error is expected to take several months, during which parts of the system may be temporarily inaccessible.

Coupang Data Breach: Authentication Failures Expose Customer Data in South Korea
South Korean e-commerce giant Coupang experienced a significant data breach between April and November 2026, with an additional access attempt in January. South Korea's Deputy Minister for Cybersecurity and Network Policy publicly attributed the incident to management failures and authentication vulnerabilities during a press conference on July 24, 2026. The attacker exploited user authentication vulnerabilities to gain unauthorized access to accounts without proper login credentials, leading to a large-scale unauthorized information leak. South Korean authorities emphasized that the breach was not the result of highly sophisticated intrusion techniques, but rather stemmed from fundamental security weaknesses in authentication mechanisms and inadequate security management practices. The breach resulted in large-scale unauthorized access to customer information. The unauthorized access has since been terminated. This incident has also led to a record fine of $422 million by South Korea's Personal Information Protection Commission (PIPC) and ongoing diplomatic discussions between South Korea and the U.S. due to Coupang being an American-owned company operating in South Korea.

South Korean Diplomatic Academy Suffers Significant Data Leak Affecting 10,000 Diplomats
On July 21, 2026, the Korea National Diplomatic Academy, an institution affiliated with South Korea's Ministry of Foreign Affairs, confirmed a significant data leak impacting approximately 10,000 records of current and retired diplomats. The breach, which occurred in the academy's online education system, was discovered in early February 2026 after suspicious access was reported by a government agency. An unidentified attacker exploited a zero-day vulnerability in the server software and weaknesses in system security settings, maintaining unauthorized access from April to May 2025 until February 2026. The compromised data reportedly included names, user IDs, email addresses, encrypted passwords, job titles, and affiliated departments. While sensitive personal information such as resident registration numbers, mobile phone numbers, and home addresses were not present on the affected server, the leak of diplomat information raises concerns, especially given that the full list of diplomats and personnel at overseas missions is not publicly disclosed. The Foreign Ministry is investigating the incident and has urgently shut down the compromised system. They are operating under the assumption that a substantial volume of data was compromised, though the exact scale of the damage is still being assessed. The incident highlights the challenges in detecting sophisticated attacks that leverage previously unknown vulnerabilities.

SR Bancorp's Internal Audit Provider, Mercadien, Experiences Data Security Incident
Mercadien, P.C. CPAs, an internal audit service provider for SR Bancorp and Somerset Regal Bank, reported a data security incident on July 10, 2026. An unauthorized actor accessed and acquired files from Mercadien's servers containing sensitive customer data belonging to Somerset Regal Bank. The compromised data included customer names, Social Security numbers, account numbers, identification documents, and dates of birth. Importantly, SR Bancorp confirmed that its own business systems, payment systems, customer access to accounts, and core information technology infrastructure were not affected by the incident. The bank is coordinating with Mercadien to provide notifications to affected customers as required by federal and state laws and regulatory guidance. While the incident exposes customers to potential identity theft and fraud, SR Bancorp currently assesses the financial impact as immaterial to its consolidated financial condition or results of operations. This incident highlights the significant risks associated with third-party vendors handling sensitive customer information.
