Since June 4, a “frozen card tide” involving more than 4,000 bank cards and a lot of OTC retailers has caused worry and anxiety among over-the-counter investors. With the “frozen card tide” sweeping the foreign currency circle, all over-the-counter investors are in risk, and several OTC retailers actually withdraw their orders and turn off to safeguard themselves.
It is understood that this direct reason behind the “frozen card tide” is that relevant sections are strictly looking into telecommunications fraud and funds, as well as the OTC trading area of ??the digital forex is actually the toughest hit area for telecommunications fraud and account laundering.
In accordance with data from CoinHolmes, a digital currency asset monitoring platform beneath the blockchain protection team PeckShield, in the initial 1 / 2 of 2020 alone, a total of 13,927 cryptocurrency addresses including hacking, account disks, dark net, gambling, etc. have flowed into electronic resource exchanges High-risk possessions, a total of 147,000 BTC (presently equivalent to almost 1.4 billion US dollars, 9.8 billion yuan). CoinHolmes’ information also tracked that this stolen money mainly flowed into five electronic foreign currency exchanges, Huobi, Binance, OKEx, Tiongkok Coin and Gate.io.
In a complex and uncertain policy environment, the embrace of supervision and compliance operations of crypto asset exchanges is a necessary condition for decreasing legal hazards and the building blocks for the long-term development of exchanges. Along the way of exchange conformity, KYC (know your client) and AML (anti-money laundering) will be the most typical and basic requirements.
In June 2019, FATF (Entire world Anti-Money Laundering Financial Activity Task Force) reported that it would supervise the electronic asset marketplace and needed VASP (Virtual Asset Service Provider) to start implementing FATF’s regulatory requirements by June 2020. According to the requirements of the FATF’s recent plenary meeting, the FATF will continue to monitor the potential risks of cash laundering and counter-terrorism funding in the virtual asset market in the next yr, and will evaluation the reality and influence of its requirements at that time, and conduct inspection and acceptance of the implementation of guidance.
The inflow of stolen money also produced the exchange quite distressed. Most of the groups actively cooperated with the authorities investigation and introduced anti-money laundering measures one after another. Nevertheless, it is still impossible to protect against, as well as the compliance procedure for the exchange is also seriously suffering from these stolen money.
This article, together with PeckShield, will analyze how stolen money flows into digital currency exchanges and laundered from the info and technical dimensions, and the way the exchanges cope with these stolen money, and comprehensively examine the AML anti-money laundering issues facing the digital asset market.
In half per year, US$1.4 billion in high-risk funds flowed into crypto exchanges. In accordance with information from CoinHolmes, a digital asset tracking platform owned with the blockchain protection team PeckShield, by June 30, CoinHolmes has counted 101 client attacks and a total of US$2.591 billion in stolen money , Which 14.82 million US dollars possess flown into the exchange; furthermore, there are 32 economic wallets or resource fraud cases including TokenStore, PlusToken, etc., affecting more than one million people, regarding a total of 7.518 billion US dollars in assets , Which at the very least $210 million has flowed into the exchange.
Needless to say, customer attacks and subscriptions are just an integral part of the high-risk addresses. All together, CoinHolmes has completed targeted tabs on addresses marked as high-risk and discovered that a total of 6 electronic asset exchanges have already been flown before 6 years. 13,927 high-risk possessions, a total of 147,000 BTC (current price equivalent to more than 1.4 billion US dollars, 9.8 billion yuan).
CoinHolmes has conducted statistics on exchanges that involve plenty of stolen cash, as follows:
In the initial 1 / 2 of 2020, the flow of stolen money to exchanges (picture source: PeckShield)
In the initial 1 / 2 of 2020, the problem of illicit money flowing out of the exchange (picture source: PeckShield)
By comparing the aforementioned two numbers, we find that the size of stolen cash flowing into the trade is much greater than that of the stolen cash flowing out of the trade, indicating that the trade has played a particular function in intercepting the flow of stolen cash.
Here, we fixed the statistical information context of the article simply because: a total of almost 100 million tackle labels within the three main stores of BTC, ETH, and EOS. Among them, high-risk addresses consist of exchanges, service organizations, dark webs, as well as the addresses of mixed currency providers, cross-chain centralized reselling establishments, and addresses of hackers involved with illegal episodes, etc., and possessions regarding high-risk addresses (like the dark web) are collectively known as stolen money.
Just how do mixed foreign currency servers and centralized reselling establishments help cash laundering? According to the analysis of the PeckShield protection team, the possessions initiated over the chain can be “exported” through various channels such as for example account fragmentation, multi-account transfer, mixed foreign currency service agencies, decentralized exchanges, centralized reselling agencies, and DeFi. These intermediate hyperlinks It is just like a “black box” that makes the flow of capital challenging and tough to track.
Take the mixed currency service as an example. The high-risk tackle supervised by PeckShield just has at the very least US$1.59 billion in funds flowing into the mixed currency service provider. The mixed foreign currency institution utilizes the Bitcoin UTXO function (a transaction can have several inputs and Output), and insight a lot of money laundering addresses at exactly the same time, and then mix other normal transactions in the switch connect to disrupt the flow of funds.
This makes it more difficult for the funds entering the coin mixer to be traced by technology, and also makes coin blending service providers a typical money laundering path.
The capital absorption of the mixed currency service provider continues to be counted (picture source: PeckShield)
Typical coin mixers are designed in line with the CoinJoin protocol. Having the CoinJoin protocol as an example, it constructs a deal conduct of “several deal sender addresses are transferred to several deal receiver addresses”, so that the tracker cannot establish an output tackle Strong organization with tracking events, so as to achieve the purpose of erasing traces.
However, mixed foreign currency does not imply that these digital possessions will no longer be tracked, but only makes the real flow more complicated. Having PlusToken as an example, the money involved in the case are continuously being “mixed”, and large money are put into a lot of small money, which decentralizes monitoring targets and escalates the resources and labor expenses required for monitoring.
Along with flowing into currency mixing program tools, quite a few stolen assets will flow to centralized reselling institutions such as for example ChangeNow and CoinSwitch. Since these establishments do not need user KYC and may manually help out with reselling various electronic assets, they have also become a more mainstream cash laundering channel.
Take the theft of the Korean trade Upbit as an example. At the end of 2019, the Upbit trade suffered a black attack and dropped 34,000 ETH. In the past six months, ?customers have continuing to handle operations such as for example asset transfer, trimming, decentralized transfer, foreign currency mixing, and cash laundering, and they have finally washed almost all their assets in recent days.
As shown within the amount below, after attacking Upbit’s deal proceeds, black customers were transferred in four layers, and finally their money flowed to exchanges such as for example Binance, BitMax, Gate.io, Huobi, BYEX, KuCoin, and OKEx.

On June 10, 2019, the wealth management pocket TokenStore was exposed as a suspected runaway. Within the scope of statistics, at the very least thousands of users’ possessions of hundreds of millions of yuan had been taken away, including BTC, ETH, ETC, XRP, EOS, LTC, USDT, etc. A number of mainstream cryptocurrencies.

On March 24, 2019, the DragonEX trade was hacked, leading to the theft of a lot of users and platform electronic assets. The stolen digital currency possessions incorporated: BTC, ETH, EOS, XRP, ETC, USDT, etc.

So how exactly does the trade handle the inflow of stolen cash? After reading the aforementioned data analysis and principle description, I believe you curently have a particular knowledge of the complexness of cash laundering.
Here, we have to clarify one thing. The final inflow of stolen money into the trade is not an issue of the trade. It is problematic for the trade to fully and effectively recognize the legitimacy of money, which is also one of the victims of the inflow of stolen money. For this reason, how to set up a mature blowing wind control system to prevent the free flow of stolen money is particularly critical for the top exchanges.
Contacted the representatives of the five exchanges that appeared above, Huobi, Binance, OKEx, Tiongkok Foreign currency and Gate.io, and asked them how to approach the stolen cash flowing into the exchange. As of press period, Huobi, OKEx, Zhongbi and Gate.io have introduced people to their danger control techniques, and Binance has not yet responded.
Let’s have a look at the specific commonalities and variations between these four top exchanges in working with the inflow of stolen money.
The relevant person in charge of OKEx introduced to OKEx that OKEx has established a blockchain-based big data risk control system focused on risk monitoring, analysis and removal. With regards to strategy, OKEx has refined nearly one thousand danger control guidelines and deployed them in all-scenario company lines, within the entire life routine of the account. With regards to models, OKEx has established a number of machine learning versions, which can efficiently identify fraudulent strategies such as database accidents, Trojan horses, phishing, cracking, and social executive fraud, and realize hourly danger control model modifications.
For handling the inflow of stolen cash, OKEx’s general process would be to identify the stolen cash, then cooperate using the regulatory specialists to freeze the relevant balances, and finally perform strict KYC and present proof of the legal way to obtain money before OKEx will unfreeze the relevant balances. In accordance with OKEx’s background information, OKEx has frozen hundreds of suspicious balances in June this season alone.
The person in charge of the relevant department of Huobi said: Concerning the problem of the inflow of “black coins” into Huobi, actually, the inflow of “black coins” is a common phenomenon. Huobi is among the world’s largest electronic asset exchanges because of its large market share. , The quantity of down payment and withdrawal can be high, as well as the inflow of “black coins” is also unavoidable.
According to the actual operation situation, the inflow of ¨black coins〃 seen by most monitoring agencies actually originates from the assets that users privately traded over the counter OTC. The form of private over-the-counter transactions makes the chain appear to be 100 % pure transfers. Become not really simple. Furthermore, the transfer romantic relationship over the chain isn’t as simple because the information presentation. Some account disks privately induce users to withdraw cash to the account disk deal after buying cash on Huobi. When participating in the cash out of the account disk, users may withdraw cash back again to Huobi. It will also cause the inflow of so-called “black coins”. Needless to say, there are also cases where attackers and hacking users come in right to launder money.
In reaction to like incidents, Huobi states it has a total risk control system and stringent procedures to deal with like incidents.
Huobi has KYC, KYT (Know Your Deal), AML, and a good on-chain monitoring system. Counting on Huobi’s very own security intelligence system, it monitors the full amount of possessions moving into Huobi instantly from the level of events, addresses, and resource tracking, and can initiate risk control measures for suspicious transactions based on various risk control strategies triggered according to the situation. When suspicious possessions are located, the withdrawal of coins moving into the focus on account will be immediately restricted, and there may also be basic safety reminders for functions that may cause the increased loss of user possessions.
Furthermore, Huobi stated that it has been actively cooperating with general public authorities in combating offences through scientific and technological assistance stations and judicial investigations, and has taken required actions relative to the requirements of general public authorities.
Gate.io said that Gate.io has established a special system for these stolen money to monitor the blacklisted addresses, including the EOS tackle of PlusToken, the addresses transferred after Upbit is hacked, etc., and that the incoming money will be frozen instantly. Gate.io has now cooperated using the judicial specialists to block multiple inflows of TokenPlus and Upbit money.
Furthermore, Gate.io also has its KYT platform stop.info, that may affiliate the relevant tackle and controller of any tackle, link suspicious routines with real-world entities, and monitor suspicious wallets instantly.
The relevant person in charge of China currency told that China currency platform built a summary of black currency addresses, that was updated by special personnel from time to time. The system supervised that the black currency address was transferred to China and taiwan currency platform and immediately frozen the account; the legal currency trading region Advertisers can flexibly fixed the multi-dimensional situations of the counterparty, such as for example trading T+1 times to withdraw cash, etc., to prevent black cash and black cash transfer. Furthermore, China Coin has set up a “National One-click Record” button on its website and app, permitting users to rapidly and conveniently report some other clients they consider suspicious.
The largest challenge faced by exchanges in anti-money laundering. In the response of varied exchanges to the handling of inflows of stolen money, it is found out that the leading exchanges have begun to determine a avoidance and control mechanism to deal with stolen money and are gradually improving.
In fact, before two years, the knowing of electronic currency exchanges to warn and prevent the inflow of stolen funds has increased significantly weighed against before 2018, but there’s still quite a distance to look in user education.
Take the freezing card tide that happened in June, an insider from the leading exchange stated: ¨Can you believe it? A Weibo huge V who has been in the currency circle for more than four years, after finding that his card was frozen, gave him crazy We known as and yelled at him and told us to defrost him. He didn’t actually distinguish between frozen cards and frozen coins, and believed we had frozen his bank cards.”
The exchange does not have the right to freeze any user’s bank card. This expert belongs to the lender. When an unusual transaction is discovered, the exchange is only permitted freeze cash and wait for the police to research.
At present, the legislation and supervision of electronic currency transactions generally in most countries and regions are not clear. Although the regional judicial or general public security system has received a lot of cases linked to blockchain fraud, there is absolutely no clear legal policy for reference. For that reason, the treatments for such cases are more challenging, and there will be a certain period window; furthermore, most exchanges will not privately process the user’s possessions if you find no situation in the authorities. It also results in time for thieves to launder cash.
In accordance with PeckShield, the monitoring of the cases they handle needs the following approach: on-chain blacklist tackle collection and supervising △ blacklist tackle asset change caution △ waiting for the victim to call the authorities offline △ police force intervention to acquire evidence from your exchange △ trade to target assets Frozen △ subsequent distribution of frozen assets or subsequent public sale.
At present, it requires at the very least 1-2 organic months for this group of processes to go down, also it may just take a short while for an illegal asset to be used in money laundering purchase. For that reason, the PeckShield protection team feels that the problem of the time home window for tracing stolen funds is the biggest challenge facing the exchange’s anti-money laundering.
Furthermore, the massive amount stolen money we mentioned above flows into mixed currency servers and centralized reselling institutions, that is also one of the main risks faced by exchanges in anti-money laundering. They greatly increase the problems and cost of stolen cash tracking.
In summary, the current anti-money laundering and other conformity issues facing electronic currency exchanges are still severe, and there’s still plenty of area for improvement in working with the inflow of stolen cash. I am hoping that prior to the FATF regulatory sledgehammer drops in 2021, exchanges can explore To build up a far more efficient and transparent anti-money laundering treatment for provide investors having a safer and more reliable trading atmosphere.
