“51% Attack” Hit Ethereum Classic: A Full Analysis Of The Process

As we have reported earlier, Ethereum Classic was hit by 51% attack, it means that hackers obtained more than 50% of network’s mining hashrate.

A Malicious “51% Attack” Hit Ethereum Classic, The Loss Allegedly Accounts For $460 000

Slowmist, Chinese-based blockchain journal, has released a full report on the attack. The earliest hit occured on January 5, the culprit hacked some exchanges, like Bitrue, Coinbase, Gate.io, however, this was noticed only two days later.

The first action was a transfer of more than 5000 ETC from Binance to the criminal’s address 0x24fdd25367e4a7ae25eef779652d5f1b336e31da. This amount of coins moved to a mining node, that created block 7254355. After that, the hacker deposited 4000 ETC to Bitrue exchange in block 7254430, yet, this transaction vanished from the Ethereum Classic chain. Another 9000 ETC was stolen in the same way. The Bitrue address 0x2c9a81a120d11a4c2db041d4ec377a4c6c401e69 no longer exists, and the official history is clear. Though, Bitrue managed to save some records:

The scheme of the hacker attack is simple:

  • make a deposit;
  • withdraw to a safe address;
  • to double coins – just move the coins to other addresses.

One of the biggests victims is Coinbase exchange. It was estimated that the loss from the attack accounts for $1 million. The above-mentioned report also provides the information about two attacker addresses which were blackmailed by Coinbase later. They are:

– 0x090a4a238db45d9348cb89a356ca5aba89c75256
0x07ebd5b21636f089311b1ae720e3c7df026dfd72

In Twitter, one of users (nickname: @OGBTC) claimed that he knew the culprit personally.

Another user (nickname: @sebseb7) indicated that it was he who knew the hacker.

The “51% Attack” is over for now. All we can do is to estimate the losses and to take measures so that it will not happen again.

The report also stated:

“[W]e recommend that all digital asset services platform block transfers from the above malicious wallet addresses. And strengthen the risk control, maintain a high degree of attention, and be alert to double spend attacks that may erupt at any time.”

Japan Released New Rules In Crypto Margin Trading

Japan is a progressive country in terms of economy, as well as cryptocurrency regulation. This time Japanese financial authorities have released a new set of rules regarding crypto margin trading.

Margin trading is a strategy that allows a trader to buy more stocks than you can afford on money borrowed from a broker (similar to loan).

The Cabinet of Japan approved draft amendments to Japanese financial instruments and payment services laws on Friday. In fact, they will limit leverage in virtual currency margin trading at two to four times initial deposits. Such restrictions are a common practice in foreign exchange trading.

All crypto exchanges throughout the country are bound to get governmental registration. This type of registration will differ from that adopted in 2017, which was mostly focus on preventing money laundering. However, these rules make exchange operators be monitored in a way similar to securities traders to protect investors.

These crypto exchange operators will be classified into categories to differentiate those who involved in margin trading from those who issued ICO tokens. This will help to distinguish unsavory offerings that are similar to frauds or Ponzi schemes and protect investors from losing their money. The new rules will come into force in April 2020. All margin cryptocurrency exchange operators have to be registered within 18 months of that date.

Such a time limit is set to take down unregistered “quasi-operators” which conduct operations without governmental approval. A senior FSA official said:

“We intend to motivate operators to do what they can to become registered.”
