Lessons From The Recent Kucoin $150 Million Crypto Hack Incident

Cyber security threats have been in existence since the beginning of the internet and occur on a daily basis using sophisticated means. Criminals and organised hackers are targeting exchanges to extract lucrative amounts of wealth. From 2012, at least 46 cryptocurrency exchanges have suffered major hacks. A record number of 19 crypto exchanges were compromised by hackers in 2019 alone, with the number decreasing in recent years. Liquid said the incident took place after hackers took control over its “warm” wallets, which are cryptocurrency accounts where exchange platforms keep funds for daily transactions. The intrusion was traced back to Quoine, Liquid’s Singapore subsidiary, the company said on its Japanese blog. Cryptoexchanges store users’ cryptocurrencies and ordinary money in conventional bank accounts. For cybercriminals, getting involved with ordinary money is risky; to get away with stolen loot, they would need to cash it quickly before the bank had a chance to freeze the accounts. Again, just like the Mt. Gox hack, a hot wallet was responsible for the theft.
Following its shut-down, in 2018 a class action lawsuit for $771,000 was filed against the cryptocurrency platform known as BitConnect, including the platform promoting YouTube channels.

The final blow came in February 2014, when the exchange suspended Bitcoin withdrawals and announced they’d lost over 850,000 BTC (around 6% of Bitcoin’s circulating supply at the time). According to Mt. Gox, hackers stole 744,408 BTC from customer wallets and 100,000 BTC along with $27 million cash from Mt. Gox between 2011 and 2014. We expect this term to be negatively correlated with μ since a higher threshold implies less frequent hot wallet refills. Note that we have suppressed the implicit dependence of c1 and c2 on T for the sake of clarity.
The loss amounted to $72 million at the time of the breach and would be worth more than $6 billion today. Worth of bitcoin was stolen after a cyber attack hit the cryptocurrency-mining platform NiceHash.

The fruitful field for them is hot wallets that are connected to the internet and usually run on a centralized system. The main benefit of cryptocurrency is that it does not use banks for verifying transactions but relies on blockchain technology that uses a peer-to-peer system when money goes directly from the sender to a recipient. Johnny Lyu, the CEO of crypto exchange KuCoin, confirmed it was aware of the hack and KuCoin had frozen the addresses of the hacker. Bitcoin-fueled illegal activity does not account for most use of blockchains, but it does remain significant and continues to grow, according to Chainalysis. Ransomware, for example, is a billion-dollar business made possible by cryptocurrency, while anonymous darknet markets moved over $600 million in Bitcoin in 2019.
Elliptic, a blockchain analytics company, said its analysis showed that about $97 million in cryptocurrencies have been obtained by the hackers. Elliptic, a blockchain analytics company, said about $97 million in cryptocurrencies have been received by the hackers. On June 17, 2016, the DAO was hit by an attack exploiting numerous vulnerabilities, particularly the recursive call bug. In this case, the attacker could “split” from The DAO smart contract recursively, thereby withdrawing their funds multiple times before the smart contract balance was updated. By the next day, the attacker had transferred 3.6 million ether — one-third of the total investment — into the newly created child DAO, valued at around $70 million at the time. The DAO was funded via a 28-day token sale in May 2016 which attracted over 18,000 investors.

According to Lon Wong, president of NEM Foundation, the hack was “the biggest theft in the history of the world.” Due to Coincheck’s weak security, the hackers had no difficulty in accessing the funds and transferring them.

The first attack happened in 2011 when hackers used stolen wallet credentials to transfer about 80,000 BTC to another wallet. McCaleb later sold the exchange to Mark Karpelès, who became the CEO and largest shareholder. The former owner retained admin rights to audit transactions and was entitled to Mt. Gox’s profits for six months. We begin by noting that the time between hot wallet thefts is given by the exponential distribution. Previous work on mitigating losses due to Bitcoin theft has focused on designing protocols that make it more difficult for private keys to be divulged and misused.

In theory, transactions of value as small as 1 × 10−8 BTC, or 1 Satoshi, are possible, so our unit could just as well have been satoshis. Tuples, but includes all of an organization’s data, is also clearly feasible, and would yield results that reflect both macroscopic trends and recent history. These transfer times, however, are determined by continuous probabilistic processes constrained by the discrete boundaries 0 and μ. As a result, the probability function describing the time of the kth transfer is dependent on the probability functions of the previous transfer times. Clearly the survival function (the probability that no theft occurs before time s+t) has Introduction in Crypto Trading no dependence on s. Unlike multisig transactions, threshold signatures constitute client-side technology, as they are not built-in to the Bitcoin protocol. It doesn’t matter how professional a trading interface looks, the back office is what really matters when it comes to attracting the big money.

In practice, they are the most tempting target for hackers in the entire ecosystem.

It was ERC-20 tokens mainly, but some amounts of BTC and ETH were lost too. Hot wallets refer to places where cryptocurrencies are stored but unlike cold wallets, they are connected to the internet. While this does make it easier to facilitate transactions, hot wallets come with added security risks compared to cold wallets – a fact that gains added significance in light of incidents like the one befalling EXMO. Bitfinex is another cryptocurrency exchange that has lost a large sum of its customer funds in a hack but ultimately made a spectacular recovery.

Balancer CTO Mike McDonald explains that the attacker had borrowed $23 million in WETH tokens in a flash loan from dYdX.

Launched in 2013, the Hong Kong based crypto exchange was one of the first regulated platforms in the world.

Note that it is possible for an empty hot wallet to encounter withdrawal requests, which, without a supporting cold wallet, it would not be able to fulfill. For now, however, we will allow the abstraction of a negative hot wallet balance. This mass function describes the probability that in any given hour, k Bitcoins arrive in net, after withdrawals are subtracted from deposits. Using it, we will now construct a series of models, incrementally introducing elements of the original problem to a preliminary setup consisting of only the hot wallet and excluding all thefts. 14], determining the legitimacy of transactions is outside the scope, and antithetical to the motivations, of the Bitcoin system.

In the case that a single device is compromised, Alice can move her bitcoins to another safe address, by constructing a transaction with her two remaining keys. And if the above isn’t enough to scare you, my one last word of advice would be to make sure that you don’t store your bitcoins on any exchange. See our post on cryptocurrency wallets for more details on how to store your bitcoins.
