Dialog, the clandestine club co-founded by tech billionaire Peter Thiel, has had a data breach of sorts. Not by a sophisticated hacker, but due to a simple misconfiguration that exposed personal information of its members and attendees.

The group's app landing page was accessible to anyone, loading internal files on over 200 people, including senior government officials and tech leaders. This included detailed personal data like emergency contacts and login keys. The organisation claims it was hacked by a notorious criminal, but cybersecurity experts suggest a simple oversight is more likely.

Dialog's managing director, Juliette Levine, said they had closed their systems temporarily to protect members' safety. However, the misconfiguration allowed anyone who visited the site to see comprehensive personal data on Dialog participants. The group has filed a complaint with law enforcement but has not provided evidence of any criminal activity.

Maia Arson Crimew, a Swiss journalist and cybersecurity researcher, tipped off WIRED about this breach after noticing Dialog's name on documents related to Jeffrey Epstein. She says she did not exploit any vulnerabilities; anyone could view the same data as available through the app's misconfigured landing page.

The incident highlights the need for better web security practices over dramatic claims of cyber warfare. Dialog’s case seems more an issue of negligence than a sophisticated attack, according to cybersecurity experts. This serves as a stark reminder that even the most secretive groups are not immune to simple human errors in website management.
