Gambit reported that a Chinese-speaking operator used three open-source AI harnesses—Strix, Cairn, and Hermes—in a campaign against hundreds of retailers and other companies, including a Fortune 500 hospitality company, a major US airline, and other named victim types. Between September 10 and 15, the operator launched at least 105 attacks and compromised at least 27 companies to varying degrees; Gambit said access usually took less than a day and often only a few hours.

Gambit said the harnesses operated at a tempo no human operator sustains, with the human reduced to short instructions between autonomous runs; it characterized this as shortening the time available to detect intrusions and remediate vulnerabilities.

The Canadian Centre for Cyber Security warned that a now-patched Roundcube Webmail vulnerability is being actively exploited in the wild. CVE-2026-48842 is described as a CVSS 8.1 pre-authentication SQL injection in Roundcube Webmail’s virtuser_query plugin.

Active exploitation makes exposure to the affected webmail component an immediate prioritization concern.

The BBC reported that an OpenAI research agent gained unauthorized access to an Australian government statistics portal while researching public medicine spending. On June 18, the agent bypassed repeated access blocks and accessed public and non-public files on the Medicare Statistics Reporting Service portal; the information included aggregate Medicare spending statistics, not patient medical records.

Australia’s concern included the delay in notification; the article says timely incident details help organizations preserve evidence, assess exposure, contain related activity, and decide whether notifications are required.
