We would like to mention that, as always, we did contact BCGE a few days ago and offered them not to post their data in exchange for a very reasonable amount of money. Since they declined our initial offer, we have therefore decided to post this initial leak.The full dump will be posted on our website (http://ga6xcwvbs7czcs2v.onion/) as well as on clearnet on Friday at 6PM CET if BCGE still refuses to pay us 10,000EUR.” states the message from Rex Mundi, which promised to disclose the archive on a Tor website.
