Hacker exploits EOS smart contract to steal $200K from gambling app-Computerfanfield

A million-dollar EOS gambling dApp suffered a major blow, just days after declaring itself to be the safest of its kind. Hackers have taken 40,000 EOS ($200,000) from the operating wallet of EOSBet by exploiting vulnerabilities in its smart contracts.

“[…] A few hours ago, we were attacked, and about 40,000 EOS was taken from our bankroll,” an EOSBet spokesperson informed users. “This bug was not minor as was stated previously, and we are still doing forensics and piecing together what happened.”

EOSBet devs have since taken the dApp offline while they figure out exactly what happened. A spokesperson does admit that hackers were only successful due to a fault in its code.

“[EOSBet] should be back online relatively quickly. We have narrowed down the bug to a faulty assertion statement in our code.” the EOSBet spokesperson added. “After talking with other developers and BPs, it seems like other games were also attacked using this same exact code (abi forwarder.)”

It appears hackers were able to call EOSBet’s ‘transfer’ function externally, using a fake hash. This tricked EOSBet’s system into illegitimately sending a huge amount of EOS. A keen-eyed Redditor was the first to share the discovery. Hard Fork has since corroborated the hack is indeed authentic.

Taking a look at the EOS blockchain, though, we can see some curious events. It seems scammers, inspired by Twitter’s cryptocurrency scambots , have invaded the EOS blockchain in order to take advantage of the current chaos.

Small amounts of EOS have been sent to the attacker’s account with some threatening messages attached. Using an account name very similar to the official EOSBet wallet, someone is sending seemingly official communication in a bid to appear legit:

The message roughly translates to:

Then, the fake account proceeds to offer a reimbursement service in order to capitalize on the developing situation. Scammers are attempting to trick users into believing that EOSBet is reimbursing customers for any funds stolen. At time of writing, EOSBet has made no such declarations.

Note, the official EOSBet account is ‘eosbetdice11’, not ‘eosbetdicell’. Pretty sneaky.

Another reads:

It remains unclear if today’s breach is somehow connected to other unusual activity taking place on EOSBet in the past few days. Earlier this week, a lucky gambler claimed over $600,000 from EOSBet by doubling their money repeatedly over a 36 hour period.

For what it’s worth, at the time, an EOSBet spokesperson was absolutely adamant that the platform had not been hacked and that all bets on the platform were legitimate, including that $600,000.

What a difference just one day makes.

Satoshi Nakaboto: ‘Akon favors Bitcoin over ‘military-backed’ dollar’

Our robot colleague Satoshi Nakaboto writes about Bitcoin every fucking day.

Welcome to another edition of Bitcoin Today, where I, Satoshi Nakaboto, tell you what’s been going on with Bitcoin in the past 24 hours. As Faraday used to say: Shleppppppp it!

Bitcoin Price

We closed the day, September 10 2019, at a price of $10,115. That’s a notable 2.13 percent decline in 24 hours, or -$220.43. It was the lowest closing price in eight days.

We’re still 49 percent below Bitcoin‘s all-time high of $20,089 (December 17 2017).

Bitcoin market cap

Bitcoin’s market cap ended the day at $181,360,731,383. It now commands 70 percent of the total crypto market.

Bitcoin volume

Yesterday’s volume of $14,906,809,639 was the lowest in one day, 3 percent below the year’s average, and 66 percent below the year’s high.

Bitcoin transactions

A total of 339,676 transactions were conducted yesterday, which is 1 percent above the year’s average and 24 percent below the year’s high.

Bitcoin transaction fee

Yesterday’s average transaction fee concerned $0.48. That’s $3.23 below the year’s high of $3.71.

Bitcoin distribution by address

As of now, there are 16,897 Bitcoin millionaires, or addresses containing more than $1 million worth of Bitcoin.

Furthermore, the top 10 Bitcoin addresses house 5.6 percent of the total supply, the top 100 14.6 percent, and the top 1000 34.4 percent.

Company with a market cap closest to Bitcoin

With a market capitalization of $181 Billion, Oracle has a market capitalization most similar to that of Bitcoin at the moment.

Bitcoin’s path towards $1 million

On November 29 2017 notorious Bitcoin evangelist John McAfee predicted that Bitcoin would reach a price of $1 million by the end of 2020.

He even promised to eat his own dick if it doesn’t. Unfortunately for him it’s 89.8 percent behind being on track. Bitcoin‘s price should have been $99,420 by now, according to dickline.info.

Bitcoin Energy Consumption

Bitcoin used an estimated 200 million kilowatt hour of electricity yesterday. On a yearly basis that would amount to 73 terawatt hour. That’s the equivalent of Austria’s energy consumption or 6,8 million US households. Bitcoin’s energy consumption now represents 0.33% of the whole world’s electricity use.

Bitcoin on Twitter

Yesterday 18,300 fresh tweets about Bitcoin were sent out into the world. That’s 3.8 percent below the year’s average. The maximum amount of tweets per day this year about Bitcoin was 41,687.
