Bithumb Hacked Again: Over 3 Million EOS Transferred Out From Exchange’s Hot Wallet

According to early reports from security researchers, South Korean cryptocurrency exchange Bithumb has suffered a major attack that started on Friday (March 29) around 01:40 UTC. (This is the second major attack on Bithumb, with the first one occurring in June 2018, when the exchange lost $30 million in crypto.)

One of the first people to report the news of the attack on Bithumb was Dovey Wan, a founding partner at Primitive Ventures:

According to Dovey's Twitter thread and information we have gathered from other sources, here is what seems to have happened so far (all time information is in UTC):

  • The attack started on March 29 at 01:40 with the hacker creating EOS wallet "ifguz3chmamg”.
  • Between 13:16 and 15:35 on March 29, 3,132,672 EOS were transferred from wallet address “g4ydomrxhege” (which belongs to Bithumb) to wallet address “ifguz3chmamg” (which belongs to the hacker) in 16 transfers.
  • Around 15:21 on March 29, the hacker started transferring the stolen EOS to various other crypto exchanges (including Huobi, HitBTC, and Changelly). 
  • Around 16:08 on March 29, Bithumb started transferring the remaining balance at wallet address “g4ydomrxhege” to its cold wallet (“bithumbshiny"), a process that is still ongoing at the time of writing (08:42 on March 30).

Here are some more updates from Dovey regarding the stolen EOS:

And here is Binance CEO Changpeng Zhao ("CZ") providing some further information on the whereabouts of the stolen EOS:

CZ also confirmed that so far none of the stolen EOS has made its way to Binance:

Also, it seems that over 20 million XRP tokens were stolen as well:

This is the latest tweet (sent out at 04:28 UTC on March 30) from Bithumb's account:

According to the latest notice posted on Bithumb's website, it seems that the exchange thinks that this was an inside job, it has allerted the authorities, and is working on recovering the stolen funds.

Crypto Market Update: Ethereum (ETH), XRP, Bitcoin Cash (BCH), and Chainlink (LINK)

Siamak Masnavi

This article provides: an overview of how Ethereum (ETH), XRP, Bitcoin Cash (BCH), and Chainlink (LINK) has been doing over the past 24-hour period; a recap of interesting recent news that might have affected their prices (or might do so in the future); and recent useful observations from Crypto Twitter regarding these cryptocurrencies.

To give you a rough idea of how well the crypto markets are doing today, 13 out of the top 20 cryptoassets (by market cap) are currently in the green (against the dollar). 

All market data used for the price charts in this article was taken between 15:30 UTC and 16:00 UTC on 22 October 2019 from CryptoCompare, which also generated the price charts shown in this article.

Ethereum (ETH)

Since October 16, ETH has been trading between $170 and $180. 

Earlier today, Hudson Jameson, Community Manager at Ethereum Foundation, said on Twitter that he is not happy with Ethereum's current governance structure and asked the crypto community for suggestions on how it could be improved:

Ethereum Foundation researcher Vlad Zamfir had this say in his reply to Jameson's tweet:

XRP

Although XRP is up only slightly down, in the past 30-day period, the XRP price has risen 6.96%. 

Earlier today, Ripple announced that it had expanded its global regulatory team and opened an office in the heart of Washington, DC. Furthermore, Craig Phillips, former Counselor to the Secretary at the U.S. Treasury Department, is now part of Ripple's Board of Directors. Lastly, Ripple has become a member of the Blockchain Association, and Michelle Bond, Ripple’s Global Head of Government Relations, will be sitting on its board.

Bitcoin Cash (BCH)

On October 17, CryptoGlobe reported that Changpeng Zhao (aka "CZ"), Co-Founder and CEO of Binance, the world's largest crypto exchange by trading volume, had proposed (on the Binance community forum) the idea of listing BCH on Binance DEX, Binance's decentralized exchange platform.

In his post on the Binance community forum, CZ said that Binance was proposing to list (on Binance DEX) BCH-1FD, "a pegged token that tracks the value of the native asset of the Bitcoin Cash" to allow "Binance DEX users to trade BCH on the DEX." CZ went on to say:

BCH-1FD is backed by real BCH assets, and Binance, the largest cryptocurrency exchange, will provide conversion between BCH and BCH-1FD through deposit/withdraw. As such, there isn’t much development work in this token or any potential of conflict of interest.

Yesterday, Binance announced that Binance DEX had listed this new token (i.e. BCH-1FD) and that trading in the pair BCH/BNB had gone live. Since then, there have been 2116 transactions.

Chainlink (LINK)

Chainlink continues having a great October, going up almost 10% today (highest gainer among the top 20 cryptoassets).

Chainlink continues to impress the crypto markets with a non-stop flow of partnership announcements; the latest one came yesterday when blockchain startup Ultrain announced via a blog post that it "will officially integrate with the Chainlink oracle network."

Chainlink's highly impressive return on investment (ROI) figures for the past seven days, 30 days, three months, and one year are +16.04%, +52.82%, +15.71%, and +607.18% respectively.
