Detailed summary

RansomLook listed Known on 2026-07-31 as a post attributed to the Gentlemen group. The scraped source identifies the victim as Known, a New York-based marketing, creative, and media agency, but it does not include any company statement, regulator filing, or notice confirming a breach.

The available source does not disclose what data, if any, was accessed, how many individuals were affected, or whether Social Security numbers, medical information, or financial records were involved. No official notification date, regulator filing, or consumer notice appears in the provided material.

At this stage, the incident remains reported only by the ransomware tracking source. More details may emerge later through company notices, regulator records, or court filings.
