Questions about this signal
What happened in this signal?
Written by UNMC strategic communications In February 2026, the University of Nebraska Medical Center (“UNMC”) learned that REDCap, a software application UNMC uses to support research studies, quality improvement projects, and public health activities, had a vulnerability that could allow an unauthorized person to gain remote access to the application. Upon learning of the vulnerability, UNMC immediately took REDCap offline and initiated an investigation with the support of third-party cybersecurity consultants. On February 18, 2026, UNMC’s investigation determined that its instance of REDCap was subject to unauthorized access between September 20, 2023 and February 3, 2026. The investigation was unable to determine whether any personal information housed in REDCap was actually accessed, though the vulnerability made such access possible. The information housed in REDCap varied by project and by individual, but could include name; identifiers such as date of birth, address, phone number, email address, and/or medical record number; and information created or collected in connection with a research study, such as clinical information, visit dates, diagnoses, medications, laboratory results, imaging or procedure information, questionnaire responses, or other health-related information. For a limited number of projects, Social Security numbers may have been collected and maintained in REDCap. In an abundance of caution, UNMC is notifying individuals whose personal information is identified in REDCap. Please note that UNMC’s review of the REDCap projects is ongoing, and UNMC will provide notice to additionally-identified individuals upon completion of the review. While UNMC does not have evidence that information was actually accessed, it is always a good idea to review statements received from healthcare providers and report any unfamiliar services or charges to the issuing entity. In addition, complimentary credit monitoring is being offered to individuals whose Social Security numbers are identified in REDCap. To help prevent an incident like this from happening again, UNMC migrated to an updated version of REDCap that was released to address the vulnerability. This new version has enhanced logging and security controls enabled. Please note, we have no indication that any other UNMC application or system was impacted; Nebraska Medicine’s clinical systems operate independently from the REDCap application and were also unaffected by this incident. For questions about this incident, UNMC encourages individuals to contact the dedicated call center at (844) 403-4589 between 8:00 a.m. and 5:30 p.m. Central Time, Monday through Friday, excluding US holidays.

Origin Energy Discloses Data Breach Affecting 900,000 Customers
On July 28, 2026, Origin Energy, a major Australian energy company, publicly confirmed a significant data breach impacting approximately 900,000 current and former customers. The breach led to unauthorized access and exfiltration of personally identifiable information (PII), including names, addresses, dates of birth, phone numbers, account details, and partial payment information such as the last four digits of credit cards or the BSB and last three digits of bank accounts. Origin Energy first identified a potential security threat in early July 2026, which was initially not deemed credible. However, new information on July 22, 2026, confirmed a security incident had occurred, prompting immediate action and notification of authorities. An alleged hacker provided a media outlet with a sample of 50 customer records and screenshots of internal Origin Energy systems, corroborating the data exfiltration. The incident is currently under investigation by Australian authorities, including the Australian Cyber Security Centre, the National Office of Cyber Security, the Australian Federal Police, and the Office of the Australian Information Commissioner. The specific technical vector used for initial access remains undisclosed.

DoorDash Confirms Data Breach After Social Engineering Attack
DoorDash, the popular food delivery platform, publicly acknowledged a cybersecurity incident that compromised the personal information of an undisclosed number of users. The breach, which occurred on October 25, was a result of a social engineering attack targeting a company employee. This allowed an unauthorized third party to gain access to DoorDash's internal systems. The compromised data varied by individual but potentially included first and last names, phone numbers, email addresses, and physical addresses of customers, Dashers (delivery drivers), and merchants across the United States, Canada, Australia, and New Zealand. DoorDash emphasized that no sensitive financial information, such as Social Security numbers, government-issued IDs, driver's license details, bank information, or payment card data, was accessed. The company's security team identified and shut down the unauthorized access shortly after its detection, launched an internal investigation, and notified law enforcement. DoorDash has also implemented multiple security enhancements, including upgraded security systems and additional employee training programs focused on social engineering awareness. While the company has stated there is no indication the data has been misused for fraud or identity theft, affected users are advised to be cautious of unsolicited communications requesting personal information. This incident marks DoorDash's third known cybersecurity incident in six years, highlighting the persistent threat of social engineering attacks.

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.

CTIVD: AIVD en MIVD verwerken persoonsgegevens in bulkdata onrechtmatig
The Dutch intelligence services, AIVD and MIVD, have unlawfully processed personal data in bulk datasets, according to a ruling by the Committee for the Supervision of the Intelligence and Security Services (CTIVD). The report, published on July 1, 2026, states that groups of employees had unauthorized access to personal data, and large quantities of data were stored for too long. The bulk datasets, sometimes containing millions of records, include names, phone numbers, location data, social media data, and communication content, sourced from government agencies, commercially available datasets, or stolen datasets offered by criminals. The CTIVD has issued thirteen recommendations to improve the situation.
