Questions about this signal
What happened in this signal?
HARICA, a Greek Certificate Authority, announced further necessary revocations of SSL server certificates scheduled for July 25, 2026. This action affects SSL server certificates issued between March 27, 2026, and July 20, 2026. The primary reason for this renewed revocation is that HARICA removed the AIA OCSP URI access method certificate extension from issued SSL server certificates at the end of March 2026, but the Certificate Policy/Certificate Practice Statement (CP/CPS) document was not updated accordingly. Consequently, certificates were issued without this extension, contrary to the CP/CPS, making their revocation unavoidable to preserve the integrity and trustworthiness of the global certificate ecosystem. This follows an earlier revocation of certificates issued between June 15 and July 15, 2026, which included the Extended Key Usage (EKU) "clientAuth" against HARICA's policy. Affected network contact persons were to be notified by email, and while HARICA announced automatic renewal, proactive renewal via the RA Portal was recommended to avoid potential issues. User certificates are not affected by these revocations.

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.

Municipality of IJsselstein Takes Files Offline Due to Data Leak
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.

Jamf Affected by Klue Customer Data Incident
Jamf, a company specializing in Apple device management, was among roughly two dozen Klue customers impacted by a data incident. The incident, which became active on July 26, 2026, involved the Icarus threat group claiming responsibility for an attack. Further reports indicated that another hacking group might have obtained samples of the stolen Klue customer data and attempted to extort affected companies directly. While the full extent of Jamf's specific exposure through this third-party incident is not detailed, the broader event highlights the risks associated with supply chain compromises. Jamf's security efforts include initiatives like its Beacon threat-hunting service, which focuses on proactive detection and analysis of Mac threats, and its annual Security 360 report, which addresses key threats to Apple endpoints.
Iowa State University's Canvas Learning Platform Breached, Student Data Exposed
Iowa State University's Canvas learning management system was breached on July 26, 2026, displaying a hacker message that blocked access to the website and all its pages. The message advised users to "consult with a cyber advisory firm" and to "contact us privately at TOX to negotiate a settlement." This incident is part of a larger series of over 9,000 attacks affecting various educational institutions. The hackers, identified as the criminal extortion group ShinyHunters, had previously caused an outage on Canvas and are also linked to data thefts from Ticketmaster and Google. The compromised data includes names, email addresses, student ID numbers, and internal messages. Iowa State IT Security issued an email addressing the outage and advised students to seek alternative submission methods for coursework. The university's news service director, Angie Hunt, confirmed that Iowa State is one of many institutions affected by a nationwide Canvas platform outage. Instructure, the parent company of Canvas, has not provided a timeframe for resolving the issue. The group ShinyHunters claimed to have stolen over 3.65 terabytes of data, encompassing approximately 275 million records belonging to students, teachers, and staff, and threatened to release this data if their demands were not met. While the affected data may include full names, email addresses, student ID numbers, and messages, there is no evidence that passwords, dates of birth, government identifiers, or financial information were exposed. The sensitivity of some Canvas messages, which can contain medical and mental health information, adds to the concern. Officials are advising students, parents, and staff to be cautious of unsolicited messages claiming to be from Canvas or the university that request personal information or prompt immediate action. They also recommend monitoring accounts for unusual activity.

South Korean Domain Registrar Gabia Hacked, Exposing 350,000 User Records
South Korean domain registrar Gabia experienced a cyberattack on Saturday, July 26, 2026, which impacted the online connectivity of approximately 100,000 registered domains. The incident led to the exposure of data belonging to 350,000 users. The compromised information included names, user IDs, passwords, and registration numbers. This breach highlights the significant risks associated with compromised credential reuse, as a large portion of the exposure originated from "Combolist sources." Additionally, active infostealer activity, linked to malware families such as LummaC2, Redline, and Rhadamanthys, was identified, further indicating a focus on credential theft impacting both clients and employees. The incident also revealed 245 compromised employee accounts, posing an infrastructure risk, and 30,782 leaked client credentials, creating regulatory liability. The timeline of related events showed an increase in client-related incidents from August 2025 through April 2026, with a peak in March 2026, and spikes in employee-related events in January, April, and May 2026. Remediation efforts should prioritize credential hygiene, multi-factor authentication enforcement, and enhanced monitoring for suspicious login activity, particularly targeting login forms and account management services. The incident was reported by the Korea Herald on Monday, July 28, 2026.
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.
