The hack occurred on Sunday when some of the exchange’s hot wallets were breached, and the stolen assets were transferred to an unidentified wallet. GDAC reported the incident on Monday and disclosed that the exchange lost over $13.1 million in Bitcoin, Ether, Wemix, and USDT, with more than $10 million in Wemix.

According to blockchain analytics firm Arkham Intelligence, the hacker has since swapped the USDT for ETH, sending 461 ETH to cryptocurrency tumbler, Tornado Cash. The hacker used three separate wallets to take funds from two of the exchange’s hot wallets. Arkham has labeled the wallets as follows:

GDAC deposits/withdrawals suspended

GDAC has suspended its withdrawal and deposit services and reported the incident to the Korea Internet and Security Agency and the Financial Intelligence Unit. The exchange has also requested other cryptocurrency exchanges to block incoming transactions from suspicious addresses.

In a notice posted on its website, GDAC CEO Seunghwan Han apologized for the suspension of deposits/withdrawals and concern relative to the hack, adding that the firm will be working towards investor protection and safe withdrawal of funds in due course. GDAC also posted the breakdown of the digital asset quantities lost in the hack, with the hacker stealing 60.80 BTC, 350.5 ETH, 10,000 WEMIX and 220,000 USDT.

 

Crypto hacks increasing

This hacking incident comes at a time when cryptocurrency hacks have been on the rise. According to blockchain analytics firm Chainalysis, illicit actors stole $3.8 billion worth of assets last year, the largest one-year loss in crypto’s history. In addition, other crypto platforms have also suffered notable hacks and exploits in the past 15 to 18 months. Axie Infinity’s Ronin bridge, for example, suffered a $625 million hack last year, and decentralized-finance protocol Sushi was exploited for $3.3 million on Sunday.

GDAC is not the only South Korean cryptocurrency exchange to suffer a significant hacking incident. In 2018, Coinrail was hacked, resulting in the loss of approximately $40 million worth of assets, and in 2021, Upbit suffered a $50 million hack.

In response to these incidents, South Korea has taken steps to tighten regulations around cryptocurrency exchanges. In March 2021, the country’s Financial Services Commission issued a revised regulation that requires cryptocurrency exchanges to maintain stricter anti-money laundering measures and report suspicious transactions.

The GDAC hack is a stark reminder of the risks associated with cryptocurrency investing and the importance of implementing robust security measures. Investors and cryptocurrency exchanges should take note of this incident and ensure that they have adequate security measures in place to protect against potential hacks and exploits.

Upbit Launches Campaign for Recovery of Mistakenly Transferred Assets

Upbit Launches Campaign for Recovery of Mistakenly Transferred AssetsUpbit, the cryptocurrency exchange operated by Dunamu, announced on Tuesday (local time) that it is launching a campaign where users can get back the digital assets that they have transferred mistakenly as part of heightened efforts to protect investors and minimize their losses due to such errors.Photo by Luis Villasmil on UnsplashRole of secondary identifiersAmong the virtual assets that Upbit allows users to deposit, some require users to accurately input their unique identifiers — like a Destination Tag (D.tag) or Memo — in order to properly process a deposit. A D.tag or Memo is an additional address used to identify a transaction recipient beyond a wallet address, which is often required when trading altcoins like Ripple (XRP) and Monero (XMR). In the case of XRP, both the exchange address and the D.tag must be entered accurately for deposits to be processed properly.Enhancing investor convenienceHowever, misdirected transfers caused by incorrect or missing secondary deposit addresses occur quite frequently. Many users also remain unaware when their virtual assets have been mistakenly transferred.In response to this issue, Dunamu has organized its latest campaign to make it easier for Upbit users to recover the virtual assets that they mistakenly sent. A user can access the campaign page on the official Upbit website and search for the transaction ID (TXID) of the deposit where the secondary address was either not entered or entered incorrectly. If a matching deposit is found, they can click “Apply for Recovery” to submit a one-on-one inquiry.Previously, users were required to manually enter information such as the name and quantity of the cryptocurrency, as well as the TXID in the one-on-one inquiry. Now, this information is automatically filled in through the TXID search, boosting user convenience.In an effort to encourage campaign participation, Dunamu also said that it will waive all fees for the recovery of mistakenly transferred assets until the end of the year.As of July, the exchange has successfully processed over 99.5% of the total 45,474 recovery requests that it has received over the past five years by leveraging its industry-leading technical expertise.“Upbit will continue its efforts to protect user assets and provide convenient services,” Dunamu said.Global recognitionMeanwhile, Upbit has secured 9th place in the Kaiko Exchange Ranking for the third quarter of 2023, ranking first among Korean exchanges. Kaiko is a crypto market data company with offices in Paris, London, New York, and Singapore.The ranking evaluates exchanges based on the following criteria: governance (30%), security (20%), liquidity (15%), business (15%), technology (10%), and data quality (10%). Upbit earned a score of 76 points.Coming in first overall on the list was Coinbase with 90 points, directly followed by Bitstamp and Kraken with 86 and 82 points, respectively. Among Korean exchanges, Korbit ranked 15th worldwide with 72 points, followed by Bithumb in 17th with 72 points, then Coinone in 27th with 59 points.

Research Center Highlights Overvaluation in Overseas Crypto Holdings Reported to Korean Tax Agency

Research Center Highlights Overvaluation in Overseas Crypto Holdings Reported to Korean Tax AgencyThe Korbit Research Center, affiliated with one of South Korea’s leading cryptocurrency exchanges, Korbit, has raised questions about the size of overseas cryptocurrency holdings reported by Korean individuals and businesses to the National Tax Service.Photo by REDioACTIVE on PixabayThe issue of market-making activitiesThe center noted that following the 2017 initial coin offering (ICO) boom, many enterprises that issued cryptocurrencies through offshore entities might still be holding onto their native tokens. This would have resulted from their inability to distribute these tokens to the market after the speculative bubble burst. The center believes these reported values could have been influenced by the issuers’ market-making activities, possibly inflating their worth.According to the National Tax Service, Korean individuals and corporations hold a total of KRW 130.8 trillion (around $98 billion) in overseas crypto accounts. Notably, 73% (KRW 120 trillion) of this sum is held by 73 corporate entities.Highlighting a critical aspect of cryptocurrency valuation, the Korbit Research Center pointed out that when tokens are priced based on market-making activities, they may be overvalued. They further underscored that even if the true value of overseas holdings by these entities is only a tenth of the reported sum, a figure like KRW 12 trillion is still substantial.Retail investors seeking overseas optionsFurthermore, the center touched on retail investors, noting that the KRW 10 trillion in their offshore accounts indicates a gap in services offered by Korean crypto enterprises. It suggests that individual investors might be exploring foreign markets due to domestic limitations like the absence of derivatives and lending options.Given the borderless nature of the crypto industry, Korean individuals readily turn to overseas services that cater to their needs. The Korbit Research Center estimates a KRW 10 trillion unmet demand in the domestic crypto sector, suggesting that stringent local regulations might be driving capital outflows.
