What happened
According to a headline attributed to SEC EDGAR, RadNet, Inc. discloses a cyber incident in an SEC Form 8-K filing, dated 2026-11-09 (SEC EDGAR: RadNet, Inc. discloses a cyber incident in an SEC Form 8-K filing). That is the only statement about an incident in the material we have, and it comes from a headline, not from the filing text.
The document at that URL is Exhibit 99.1, a press release dated November 8, 2026. According to SEC EDGAR, it reports RadNet’s third quarter financial results and revised guidance. The text we reviewed does not mention a cyber incident, an attacker, a cause, affected systems or data. We have not seen the body of the 8-K itself.
Not confirmed: what happened, when it was detected, whether any data was accessed or stolen, whether operations were disrupted, who is responsible, and how the intruder got in. No independent outlet carries this story.
Am I affected?
Not confirmed. The sources name no affected systems, data types, patients, partners or software versions, and they give no indicators of compromise or CVE identifiers. We cannot say who, if anyone, is affected.
What to do now
- Read the full Form 8-K on SEC EDGAR for RadNet, Inc. (NASDAQ: RDNT). It is the primary document, and the exhibit we reviewed does not contain the incident details.
- Watch RadNet’s own communications for any notice about the incident. None is cited in the sources.
- Do not act on rumors about scope, attacker or data loss. None are stated in the sources, and we will update this advisory if the filing or the company provides them.
