A Swiss bank that specialises in secrecy has taken on the Internet and lost.

The decidedly unintended result is a free look at some jealously guarded client secrets, including the details of one Cayman Islands trust controlled by a prominent Greek shipowner and of a $15.5m loan she made to herself.

Shipowner Anna Kanellakis, sister of John Angelicoussis, is named as beneficiary of Frantmar Trust and related company Frantmar Ventures in documents released to the worldwide web, allegedly by a disgruntled former employee of Bank Julius Baer Zurich (BJBZ).
