Ultrahuman says hackers accessed customers' wellness data
Ultrahuman, an India-based wearable health-tech startup, disclosed that attackers gained unauthorized access to a system used for internal analytics after stealing an employee’s credentials via malware. The company said the intrusion occurred on March 27, was detected within hours, and the affected system was taken offline with access revoked. Ultrahuman reported the attackers obtained "read-only" access and said wellness data for about 0.1% of users was accessed — roughly 700 customers based on a previously reported ~700,000 monthly active users — though it declined to confirm the exact number or whether data was exfiltrated. Ultrahuman said no passwords, payment information, production systems, or physical Ring devices were compromised. CEO Mohit Kumar said the company is notifying regulators and delayed user notifications while auditing scope. Ultrahuman counts Nexus Venture Partners, Steadview Capital and Blume Ventures among its investors and has raised about $103 million to date.
A consumer health-data breach highlights privacy and security risks around storing sensitive first-party user data; however the incident appears limited in scope (~0.1% of users) and does not involve payment credentials or production systems, so the immediate industry impact is modest.

Klue hack exposes customer data across cybersecurity firms
Market intelligence provider Klue disclosed a cyberattack that allowed hackers to exfiltrate customer data from connected cloud systems. Klue said intruders gained access on June 12 using a “compromised legacy credential” tied to an integration tool that links customers’ cloud data (such as Salesforce) to Klue. The cybercrime group Icarus claimed responsibility and threatened to publish the stolen data if a ransom is not paid. Multiple Klue customers — including Gong, Jamf, HackerOne, OneTrust, Recorded Future, Snyk, Sprout Social, Tanium, Insurity and Huntress — have confirmed data theft of business contact and some account information. Klue engaged CrowdStrike for incident response and disconnected integrations to block further access. The company has not disclosed how many customers were affected or how the credentials were obtained.
Apollo Global Management confirms cloud data breach
Apollo Global Management confirmed a cyberattack on parts of its cloud infrastructure in which attackers used social-engineering techniques to gain access between July 6 and July 10, 2026, and exfiltrated large amounts of personal information. A notification filed with the California Attorney General says stolen data reportedly included names, birth dates, contact details (including home addresses) and Social Security numbers; it does not specify whether affected records relate to Apollo employees or staff at portfolio companies. Security researchers say the incident is part of a broader extortion campaign targeting large financial and private-equity firms—Google-linked teams have associated the activity with groups labeled Falcon, Helix, Pink and Redact—and that attackers harvest credentials and demand ransoms. Apollo has not disclosed whether ransom demands were met or the full scope of the breach.
Hugging Face confirms breach of datasets and credentials
Hugging Face disclosed a security breach on July 20, 2026, saying attackers exploited a malicious dataset to run code on its servers, escalate privileges, and access internal datasets and service credentials. The company revoked and rotated compromised credentials, fixed the exploited vulnerability, and urged users to rotate any keys stored on the platform. Hugging Face attributed the attack to an external AI agent that operated across many short-lived sandboxes with self-migrating command-and-control, and said its anomaly detection and a locally hosted LLM helped analyze server logs after a commercial provider’s guardrails blocked analysis. The company has engaged forensic specialists and law enforcement and continues investigating whether customer or partner data was stolen.
