Bitcoin Tumbles After Major Crypto Exchanges Subpoenaed For Manipulation, Coinrail Hacked

Bitcoin and other cryptocurrencies flash-crashed Saturday night, one day after the US Commodity Future Trading Commission (CFTC) sent subpoenas four cryptocurrency exchanges in an ongoing probe into bitcoin manipulation that began in late July – following the launch of bitcoin futures on the CME, according to the Wall Street Journal. CME’s bitcoin futures derive their final value from prices at four bitcoin exchanges: Bitstamp, Coinbase, itBit and Kraken. Manipulative trading in those markets could skew the price of bitcoin futures that the government directly regulates.In delay reaction, Bitcoin fell as much as $433 or 5.6% in Saturday night trading, with some noting that the flash crash happened shortly after a 90th ranked crypto exchange, Coinrail, had suffered a “cyber intrusion”, and was likely the more relevant catalyst for the crypto price drop.


CoffeeMiner: Hacking WiFi to inject cryptocurrency miner to HTML requests – ArnauCode – Blog

Some weeks ago I read about this Starbucks case where hackers hijacked laptops on the WiFi network to use the devices computing power to mine cryptocurrency, and I thought it might be interesting perform the attack in a different way.

The goal of this article, is to explain how can be done the attack of MITM (Man(Person)-In-The-Middle) to inject some javascript in the html pages, to force all the devices connected to a WiFi network to be mining a cryptocurrency for the attacker.

The objective is to have a script that performs autonomous attack on the WiFi network. It’s what we have called CoffeeMiner, as it’s a kind of attack that can be performed in the cafes WiFi networks.
