Healthcare AI Company Xsolis Suffers Data Breach Impacting 1.4 Million Individuals
Healthcare technology company Xsolis, Inc. has disclosed a data breach affecting nearly 1.4 million individuals. Tennessee-based Xsolis provides utilization management and revenue cycle solutions for hospitals, health systems, and payers. The company published a data security notice in early June, revealing that unauthorized activity was detected on its systems on January 22. The intrusion resulted from a targeted phishing attack carried out two days earlier. According to Xsolis, the hackers gained access to files storing personal and protected health information received by the company from its clients, including names, dates of birth, addresses, SSNs, health insurance information, and medical treatment information. While the data breach was disclosed two weeks ago, the US Department of Health and Human Services (HHS) has now disclosed the number of affected individuals. The Xsolis cybersecurity incident was added to the HHS data breach tracker on Monday, with the number of affected individuals listed as 1,396,519. Advertisement. Scroll to continue reading. No known ransomware group appears to have taken credit for the attack on the healthcare tech company. SecurityWeek has asked Xsolis whether it was targeted in an extortion attempt and, if so, whether a ransom has been paid. The company’s disclosure indicates that it’s “not aware of any actual or attempted misuse of information because of this incident”. It’s not uncommon for healthcare-related data breaches to affect millions of people. One recent example is the incident involving the dental benefits administrator DentaQuest , in which hackers stole information from 2.6 million accounts.

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.

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.

Dropbox Suffers Data Breach in Phishing Attack Targeting GitHub Account
Dropbox, a cloud storage company, experienced a data breach when its GitHub account was compromised on October 13. The attackers gained access to 130 code repositories containing sensitive data, including API keys used by Dropbox developers. The incident was a result of a successful email phishing campaign that targeted Dropbox employees, impersonating CircleCI, a continuous integration and delivery platform. The phishing emails directed victims to a fake login page where they were prompted to enter their GitHub credentials and a One-Time Password (OTP) from their hardware authentication key. Dropbox was notified of the potential breach by GitHub on October 14. While the attackers accessed some credentials and API keys, Dropbox stated that customer accounts, passwords, or payment information were not compromised, nor were its core apps or infrastructure. The data accessed also included the names and email addresses of a few thousand Dropbox employees, current and past customers, sales leads, and vendors. In response, Dropbox is enhancing its security by implementing WebAuthn and hardware tokens or biometrics.

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.
