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.

UAE researchers introduce carbon trading platform on blockchain

UAE researchers introduce carbon trading platform on blockchainAmid escalating climate concerns, the Technology Innovation Institute (TII) in Abu Dhabi has unveiled a blockchain designed to monitor carbon emissions and facilitate trading.Announcement during COP28The institute’s Cryptography Research Center (CRC) recently announced the launch of its proprietary blockchain-powered carbon trading platform, showcasing the United Arab Emirates’ (UAE) commitment to spearheading global climate initiatives. TII CEO Ray Johnson stated:“We are proud to announce this digitized tracking and trading platform at COP28, representing the UAE’s drive to become a technology and innovation powerhouse and its commitment to leading the world’s climate action agenda.”The revelation coincides with the United Nations Climate Change Conference (COP 28), which runs until Dec. 12 and is taking place in Dubai. The conference involves nations making commitments to reduce emissions and transition various sectors toward sustainable energy sources.Photo by Matthias Heyde on UnsplashEnabling carbon trading internationallyThe newly introduced blockchain platform is poised to enable the international trade of carbon tokens, monitor greenhouse projects and incentivize participation in emission reduction initiatives. By leveraging the principles of carbon trading and tracking, organizations will gain valuable insights into their environmental impact. The platform’s deployment on the blockchain ensures transparency and encourages broader participation, compelling major players to fulfill their environmental promises.The lightweight blockchain has been developed with minimal environmental impact in mind, aligning with the broader goals of the government’s climate action initiatives. This blockchain network allows organizations to record their emissions openly, prompting users to generate tokens that quantify carbon removed from company operations through capture or trading.Moreover, the network incorporates auditors to ensure the entire process is secure, transparent, accurate and safe. This approach aims to provide the industry with accurate data on their activities without relying on cumbersome third-party expert monitoring.Harnessing blockchain’s transparencyThe move to utilize blockchain technology for addressing climate change aligns with the long-standing belief of the United Nations and various international organizations. Blockchain’s transparency and openness empower industries to have accurate data on their activities, eliminating the need for complex third-party monitoring that often comes at a higher cost.In response to growing criticism of the energy consumption associated with blockchain technology, certain firms have taken steps to adopt greener practices. Notably, in 2021, the Ethereum blockchain transitioned to a Proof-of-Stake model, reducing its carbon footprint by over 99% by eliminating miners and introducing validators. Ethereum also launched the Ethereum Climate Platform (ECP), attracting participation from industry giants like Microsoft.Furthermore, cryptocurrency companies have allocated funds for solar-powered digital asset projects, encouraging developers to embrace eco-friendly practices. This shift towards sustainable initiatives underscores the industry’s commitment to addressing environmental concerns.In a related development, in August, it was reported that the UAE Ministry of Climate Change and Environment (MOCCAE) had entered into a collaboration with the Industrial Innovation Group and the Venom Foundation to work towards a blockchain-based carbon credit system.The introduction of the UAE’s blockchain-powered carbon trading platform marks a significant step towards fostering global climate initiatives. The innovative technology not only enhances transparency and accountability in carbon trading but also aligns with the broader global shift towards sustainable and eco-friendly practices within the blockchain industry.

BIS Collaborates with Singapore’s MAS, Bringing CBDC Pilot to a Close

BIS Collaborates with Singapore’s MAS, Bringing CBDC Pilot to a CloseThe Bank for International Settlements (BIS) has recently signified the culmination of Project Mariana, a pilot initiative centered on exploring the cross-border trading and settlement of wholesale central bank digital currencies (CBDCs).Photo by Pixabay on PexelsUpdating financial market infrastructureThe bank of central banks published the findings of the project on Thursday. Conceived in partnership with the Monetary Authority of Singapore (MAS) alongside the central banks of France and Switzerland, the endeavor could have profound implications for the future landscape of financial market infrastructure.Project Mariana, conducted under the patronage of the BIS, harnessed principles gathered from the emerging world of DeFi to probe the viability of employing automated market makers (AMMs) for CBDC trading and settlement.The project involved three key facets:DeFi Ingenuity: Project Mariana took inspiration and cues from the DeFi universe, particularly AAMs, to streamline foreign exchange trading and settlement. This approach was designed to bolster market efficiency while curtailing settlement risks.Cross-Border CBDC Transactions: Hypothetical wholesale versions of the Swiss franc, euro, and Singapore dollar in CBDC form were tested for cross-border trading and settlement. The central banks of France, Singapore, and Switzerland orchestrated simulated transactions via AAMs to gauge feasibility.Interoperability and Token Standards: The project showcased the practical application of a standardized technical token format offered by a public blockchain, enabling seamless interoperability across various currencies. This interoperability element played a pivotal role in facilitating cross-border CBDC transactions.While the project represents a significant move forward for the BIS in its consideration of decentralized technology, the organization is still mindful that these decentralized tools are in their infancy and in need of further scrutiny and experimentation.With that, the BIS Innovation Hub has outlined its intent to further explore the prospective advantages and obstacles associated with DeFi-infused solutions within pertinent use cases going forward.Proof of conceptWhile the BIS and participating central banks were happy with the outcome of the project, the exercise was still a proof of concept and doesn’t mean there will be any immediate adoption of CBDCs by the participating nations.Rather, it spotlights the potentials of CBDCs and DeFi in streamlining financial transactions and enhancing efficiency. Central banks can oversee wholesale CBDCs without necessarily exerting control over the underlying infrastructure, thereby furnishing commercial banks with a potent tool for instantaneous FX trading and settlement while simultaneously mitigating credit and settlement risks.The project also shone a spotlight on certain challenges, including the logistical intricacies arising from the 24/7 availability of wholesale CBDCs. Nevertheless, the manifold advantages of instant foreign exchange trading and settlement appear to outweigh these hurdles.Central bankers are likely to want a different outcome from the use of this technology by comparison with those who are currently knee-deep in building out DeFi. One commentator on X had a cynical take on the project, stating: “Intermediaries attempting to justify their existence in an age with bitcoin.”Notwithstanding that, FX is the largest financial market in the world, where $7.5 trillion in value is traded every day. To utilize DeFi technology in that context would likely be profound, regardless of the nature of the application of the technology.
