(Adds bank statement confirming posting)
ZURICH/GENEVA, Jan 9 (Reuters) - A hacker claiming to be
behind a cyber attack on Banque Cantonale de Geneve BCGE.S on
Friday divulged confidential client information after the Swiss
bank failed to meet demands for payment.
In the latest case of a breach of customer information at a
financial firm, an anonymous person or group using the Twitter
moniker Rex Mundi said it had hacked the Genevan cantonal
(state) bank's servers and downloaded more than 30,000 emails by
Swiss and foreign clients.
Hours after the hacker's 1700 GMT ultimatum expired, the
bank issued a statement saying that the intercepted material had
been published, but added that it represented "no particular
financial risk for clients or the bank".
"At first analysis, this information is hardly critical, is
obsolete or corresponds to foreseen contents about which it has
already informed a significant number of clients concerned."
BCGE spokeswoman Hélène De Vos Vuadens said that at this
stage it appeared that all of the 30,000 mails which the hackers
claimed to have intercepted had been published, including some
affecting foreign clients.
She said that all the information was from clients'
inquiries over the Internet and did not involve their accounts,
which require several passwords or codes to access.
The hacker had earlier posted names, addresses and messages
to the bank from two people it said were BCGE clients, and said
the remainder of the data it had stolen would be make public
later on Friday if it was not paid 10,000 euros ($11,779).
"We chose not to give in to blackmail and chose instead the
path of transparency," the bank's spokeswoman said.
The hacker played on Swiss banks' reputation for helping
clients conceal information from tax authorities.
"We would like to wish a merry tax audit to all the
non-Swiss account holders listed in the BCGE files," the Rex
Mundi account tweeted on Friday, one of 61 messages that range
from detailing demands, to criticizing the bank for lax
technology security, and taunting clients who may be at risk.

"As for fiscal risks, we asked all of our clients to
regularise their (tax) situation. It is up to each of our
clients to fulfill legal requirements in conformity with the
legislation in force," the BCGE spokeswoman said on Friday.
