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.

Latvijas Valsts Mezi (LVM) Suffers Cybersecurity Breach
Cybersecurity breach reveals vulnerability of Latvia's strategic infrastructure: minister RIGA, June 26 (Xinhua) -- A recent incident in which hackers managed to access IT systems of Latvia's state-owned company Latvijas Valsts Mezi (LVM) revealed the relative vulnerability of the country's strategic infrastructure, Smart Administration and Regional Development Minister Edgars Tavars said Friday. The cybersecurity breach in LVM has caused particular concerns because the company has been entrusted with developing an electoral IT platform for Latvia's parliamentary elections, which are scheduled to take place this fall. In an interview with the TV3 channel on Friday, Tavars called on all state institutions to identify cybersecurity flaws in their own systems and learn a lession from the LVM incident. The minister believes, though, that in general, Latvian IT specialists are good enough to prevent similar incidents from repeating in the future. Tavars said that the electronic voter register, on which LVM has been working, was completed before the incident and was not at risk. In general, "we are definitely not ringing alarm bells about the elections," the minister said. LVM discovered the cybersecurity breach of its IT systems last weekend. In response, the company took all its external IT systems offline and also shut down some internal communication systems. A foreign ransomware group, which has carried out similar attacks against companies and government agencies in other countries, has claimed responsibility on the cyberattack on LVM. Cyberattack on Latvian State Forests detected LVM is one of three companies developing this year’s Saeima election system . However, the company noted that the development of the election system was kept separate and was not affected. Security measures will be reviewed as a precaution. The cyberattack occurred on Monday, June 22. According to the company, since the incident began, the external information technology (IT) systems maintained by LVM, including “LVM GEO,” the mapping service system, and the hunting app “Mednis”, have been shut down and are unavailable for security reasons. Several of LVM’s internal systems, which facilitate the company’s exchange of information with service providers and clients, have also been taken offline. LVM spokesperson Tomass Kotovičs stated that the threat has been eliminated, but it will take time to restore the systems to operation. Baiba Kaškina, head of “Cert.lv,” explained that the attack was thwarted immediately. According to her, there is no reason to believe that it was specifically targeted at Latvia. “Cert.lv” is inclined to believe that this was a commercially motivated attack aimed at demanding a ransom and demonstrating the attackers’ capabilities. The State Police Cybercrime Combating Directorate, based on publicly available information, has launched an internal investigation on its own initiative to clarify the circumstances of the incident and identify the possible perpetrator, according to the LETA news agency.

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.

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.

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.

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.
