Following the hack in August, Bitfinex, a Hong Kong-based digital currency exchange is now making efforts to communicate with the hacker.

Bitfinex hack was one of the major security breaches in the cryptocurrency ecosystem in which it reportedly lost 120,000 BTC. The site went offline for a number of days and full platform functionality going live in progressive steps.

In a latest blog post, the exchange has tried to communicate with the hacker saying that its intention is not to accuse, blame or make demands, but rather to discuss an “interesting” arrangement.

“It might be possible to reach a mutually agreeable arrangement in exchange for an enormous bug bounty (payable through a more privacy-centric and anonymous way)”, Bitfinex said.

Speaking with CoinDesk, Bitfinex chief strategy officer Philip Potter said that Bitfinex is willing to negotiate any final terms with the hacker.

"We are open to any arrangement that maximizes recovery for our customers," Potter explained. "We will consider any [and] all arrangements to that end."

For this purpose, Bitfinex has set up a dedicated email address and hopes to establish a secure line of communication with the hacker. It added:

“We understand that you will be reluctant to contact us through traditional channels. To protect your anonymity, we would like to suggest three potential communication methods:

• We believe that a combination of Tor and an anonymous email service should suffice to protect your identity and location. Encrypting your message with our PGP key further guarantees privacy from prying eyes, but to prove your authenticity to us, we ask that you provide the public key associated with 1QDBWKgfftwuraEasMGSUvj9PPrswZv19q and sign your message with the corresponding private key.
   
• Instead of using e-mail, you can send the authenticating information via Bitmessage and Tor. Our Bitmessage address is BM-2cW79647sMFe3fJKKGKAwXWwTSS293meq8.
   
• Alternatively, you can send us a message on the Blockchain using OP_RETURN. You can encrypt a message (containing your pub key) with our PGP key, split up the message into 80-byte chunks, and send transactions to 19eT7KGKo1gFjgBhEF4957wVNugkc2cakK from any one of the 2072 addresses currently holding the bitcoins in question.”

Bitfinex concluded saying, “Perhaps there is yet a different way that you’d like to communicate? If so, please initiate contact and provide instructions for your preferred method of communication. We are anxious to hear from you.”
