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.
DigiCert Security Incident Linked to GoldenEyeDog Subgroup CylindricalCanine
DigiCert's security incident in April 2026 has been attributed to CylindricalCanine, a subgroup of the China-linked cybercrime group GoldenEyeDog (also known as APT-Q-27, Dragon Breath, and Miuuti Group). The attackers compromised a support employee's device using malware delivered via a phishing lure disguised as a screenshot or document sent through DigiCert's support-ticket workflow. This intrusion granted the threat actors access to initialization codes for customers renewing code-signing certificates. By intercepting these codes, the attackers were able to obtain 27 fraudulent code-signing certificates, which were then used to sign malware, including the "Zong Stealer" campaign. DigiCert identified the incident through third-party reports of certificates being used in malware and subsequently revoked 60 certificates by April 17, with 27 explicitly linked to the attackers. The company emphasized that its root certificates were never compromised, and the breach was limited to a finite set of certificates. DigiCert has since blocked high-risk file types at ingestion, removed malicious files from Salesforce cases and chat records, and is working on sandboxing controls for inbound support attachments.

Axios npm package compromised in supply chain attack on July 23, 2026
On July 23, 2026, the Axios npm package, a widely used JavaScript HTTP client, was compromised in a sophisticated supply chain attack. The attackers hijacked a maintainer account and injected a malicious dependency, `plain-crypto-js`, into versions `axios@1.14.1` and `axios@0.30.4`. This malicious dependency was designed to download multi-stage payloads, including a remote access trojan, onto developer machines and CI/CD pipelines globally. The compromise was detected and the malicious packages were removed from npm within approximately three hours. The attack was characterized by its operational sophistication, bypassing standard security controls like MFA through a targeted social engineering campaign against the maintainer. The malicious code was capable of breaching major operating systems including Windows, macOS, and Linux. CISA issued an alert providing guidance for detection and remediation, urging organizations to monitor code repositories, CI/CD pipelines, and developer machines, and to rotate credentials that may have been exposed. Google Threat Intelligence Group publicly attributed the compromise to UNC1069, a North Korea-nexus, financially motivated threat actor. The incident highlights the significant risks associated with software supply chain attacks and the importance of robust security measures for open-source dependencies.

Accenture Confirms Security Incident After 35GB Data Theft Claim
Accenture, a global professional services company, confirmed a security incident in July 2026 after a threat actor, identified as "888," claimed to have stolen approximately 35 GB of data from the company. The stolen data reportedly includes source code, RSA keys, SSH keys, Azure personal access tokens (PATs), Azure Storage access keys, and configuration files. The threat actor advertised the data for sale on a cybercrime forum and provided a screenshot as proof of exfiltration from a private Azure DevOps repository associated with accenture.com. Accenture stated that it is aware of the "isolated matter" and has remediated its source, asserting that there was no impact on Accenture's operations and service delivery. This incident follows previous security challenges for Accenture, including a 2017 exposure of sensitive data on unsecured AWS S3 buckets and a LockBit ransomware attack in 2021.

Tata Electronics Data Leak Exposes Apple iPhone 18 Pro Details
India probes Tata Electronics breach exposing iPhone secrets India is investigating a data breach at Tata Electronics that reportedly exposed confidential information linked to Apple’s unreleased iPhone 18 Pro, the country’s IT secretary said on Thursday (July 3), marking the government’s first public response to the incident. Sensitive documents, including component lists, supplier details and images of the iPhone 18 Pro, were allegedly posted on the dark web by a ransomware group that targeted Tata Electronics, an Apple supplier in India, Reuters reported. “We are investigating,” said S. Krishnan, secretary at the Ministry of Electronics and Information Technology, adding that the case has been referred to India’s Computer Emergency Response Team, the national cybersecurity agency. The breach raises concerns over Apple’s tightly controlled global supply chain, where production of iPhones relies on multiple international suppliers. Apple is expected to launch the iPhone 18 Pro and Pro Max in September. The leaked files are said to include at least six documents revealing supplier assignments for specific components—information Apple does not publicly disclose. Tata Electronics has reportedly hired a global consultancy firm to carry out a forensic audit following the leak, which also allegedly involved documents related to Tesla, Qualcomm and TSMC being published on the dark web, according to Reuters.

Singapore Land Authority Data Breach Exposes 70,000 Records via IBM Testing Environment
Singapore Land Authority data breach exposes 70,000 records after IBM testing environment compromised SINGAPORE, July 3 — Personal data belonging to about 70,000 individuals has been compromised in a cybersecurity incident involving the Singapore Land Authority (SLA) and a cloud environment managed by IBM. SLA said the breach stemmed from unauthorised access to a dataset created for vendor development and systems integration testing, CNA reported. IBM oversees the testing environment for the Singapore Titles Automated Registration System (STARS) and eLodgment System (ELS), which are used to submit property transfer and caveat documents. Preliminary checks showed the dataset, first created in 1998 and updated periodically, was intended to contain only mock and anonymised records. It was later discovered to include real information such as names, NRIC numbers and past property addresses of around 70,000 people. SLA stressed that the affected environment is separate from its live operational systems, adding that property ownership and lodgment records in STARS and ELS remain secure. IBM has revoked access to the compromised system to prevent further unauthorised entry. As a precaution, SLA has begun notifying affected individuals and advising them on assistance measures. The authority said it is working with IBM, the Government Technology Agency of Singapore and the Cyber Security Agency of Singapore to investigate the incident and implement remedial steps. According to CNA, a police report has been lodged and the Personal Data Protection Commission has been notified. SLA has not yet disclosed when the breach occurred or how many affected individuals have been contacted.

IBM was appointed to support and maintain SLA’s Singapore Titles Automated Registration System (Stars) and eLodgment System (ELS), which underpin property title registration and the lodgement of property documents in the city-state. As part of that work, the supplier managed the development and systems integration testing environment for the two systems. In a statement on 3 July 2026, SLA said it had been informed by IBM of the incident, with preliminary investigations indicating that a dataset created solely for development and testing purposes had been accessed without authorisation. The dataset, created in 1998 and updated periodically over the years, was meant to contain only mock and anonymised testing data based on property ownership and lodgement records. However, SLA said it has since uncovered that the dataset also contained the names, National Registration Identity Card (NRIC) numbers and property addresses of the affected individuals at the time. “This information should have been anonymised but was not,” the agency said, adding that investigations are ongoing to determine how this occurred. SLA noted that the affected environment is “distinct and separate” from its operational systems, with no connection to, or compromise of, the live systems that run Stars, ELS or any other SLA systems. Property ownership and lodgement records remain secure and unaffected, it added. IBM has revoked access associated with the affected environment to prevent further unauthorised access, while SLA has identified the individuals whose information was contained in the dataset, and has begun notifying them and advising them on how to seek further information and assistance. Singapore mobilised over 100 cyber defenders to neutralise a sophisticated APT actor which infiltrated Singtel, StarHub, M1 and Simba networks in the country’s largest coordinated cyber incident response to date . Japan’s Nikkei has confirmed a major data breach that potentially exposed the personal information of more than 17,000 employees and business partners after hackers infiltrated its internal Slack messaging platform. Australian privacy commissioner warns that the human factor is a growing threat as notifications caused by staff mistakes rose significantly even as total breaches declined 10% from a record high. Philippine bank BDO is shoring up its cyber security capabilities to protect its data and systems as it moves more services to the cloud and expands its physical presence into remote areas of the archipelago. The agency is working with IBM, the Government Technology Agency and the Cyber Security Agency of Singapore (CSA) to establish the full facts and ensure remedial measures are taken. It has also lodged a police report and notified the Personal Data Protection Commission, and urged the public to remain vigilant against phishing emails, websites, text messages and phone calls from parties claiming to represent government agencies or other organisations. “We apologise for the concern and inconvenience this incident may cause,” the SLA said. The incident underscores the long-standing risk of real personal data finding its way into development and test environments , which are typically less closely guarded than production systems – a risk that is compounded when those environments are operated by third parties. It is also the latest in a series of supply chain security incidents in Singapore in recent years. In April 2025, Toppan Next Tech, a printing supplier for DBS Bank and the Singapore branch of Bank of China, was hit by a ransomware attack that saw customer data stolen by the threat actor . Some 8,200 DBS customers – mostly holders of DBS Vickers trading accounts and Cashline loans – and around 3,000 Bank of China customers were potentially affected. A year earlier, in August 2024, a hacker who gained unauthorised access to Mobile Guardian , a mobile device management platform then deployed across Singapore’s schools, remotely wiped the iPads and Chromebooks of about 13,000 students from 26 secondary schools. The Ministry of Education subsequently removed the software from all student devices and terminated its contract with the supplier.
