Hot Wallet Exploit Results in $23M Bitrue LossBitrue, a Singapore-based crypto exchange, has fallen prey to a $23 million hack due to a hot wallet exploit. The exchange has been forced to suspend all withdrawals until April 18, to provide an opportunity to conduct a thorough security review.©Pexels/Karolina GrabowskaHot wallet vulnerabilityHot wallets are used by exchanges to store small amounts of cryptocurrencies for easy access. These wallets are connected to the internet and are therefore more vulnerable to attacks compared to cold wallets, which are stored offline. In the case of Bitrue, hackers were able to exploit the hot wallet and steal cryptocurrencies worth $23 million.In a series of Twitter posts, the exchange outlined that the exploit occurred at 07:18 (UTC) on Friday. “We were able to address the matter quickly and prevented the further exploit of funds”, it went on to state.The stolen digital assets include ETH, QNT, GALA, SHIB, HOT and MATIC. Bitrue outlined that the hot wallet funds account for only 5% of overall funds and that the rest of its wallets remain secure and have not been compromised.Blockchain security firm PeckShield outlined how the funds were swapped and drained. A wallet it has labeled as “Bitrue drainer” swapped 173,000 QNT, 22.55 billion SHIB tokens, 46.4 million GALA and 310,000 MATIC for 8,540 ETH. The ether is now being held within the following address:0x1819EDe3B8411EbC613F3603813Bf42aE09bA5A5Reimbursing usersIn response to the hack, Bitrue has promised to reimburse all affected users. However, the process could take some time.The incident underscores the importance of taking precautions when storing cryptocurrencies on exchanges. Users should only keep a minimal amount of cryptocurrencies on an exchange and should not store more than they can afford to lose. Ongoing exploits, hacks and frauds exemplify the need for users to only use reputable platforms with a proven track record of security.Doubling down on securityBitrue has promised to improve its security measures to prevent similar incidents from occurring in the future. The exchange’s response to the hack has been lauded by many in the cryptocurrency community, who have praised the company’s transparency and commitment to reimbursing affected users.The cryptocurrency community has been vocal in its criticism of exchanges that fail to prioritize security. The Bitrue hack is just the latest in a series of incidents that have highlighted the importance of maintaining security in the world of cryptocurrency.It’s not the first security breach that the exchange has encountered. In 2019 Bitrue suffered a $4.7 million loss, with quantities of both XRP and Cardano (ADA) having been stolen. On that occasion, the exchange released tracking details relative to the stolen funds. Thanks to collaboration with Huobi, Bittrex and ChangeNOW, the funds and associated accounts were frozen.According to data from CoinGecko, Bitrue trades an average of $1 billion in digital assets daily, with bitcoin and ether trading pairs accounting for a large proportion of that trading volume. The Bitrue hack has been a wake-up call for the cryptocurrency community and serves as a reminder of the ongoing risks associated with storing cryptocurrencies on exchanges.

Coti plans transition to Ethereum layer-2 network in 2024Israeli blockchain developer Coti plans to introduce a scalable, privacy-focused Ethereum layer-2 protocol in 2024. This strategic move aims to extend Coti’s privacy-centric features to a wider audience within the Ethereum ecosystem.Photo by Zoltan Tasi on UnsplashIncorporating ‘garbled circuits’Taking to the X social media platform on Wednesday, Coti unveiled its plan to transition from a standalone protocol to an Ethereum layer-2. The centerpiece of the project, which Coti has termed “Coti v2: a privacy-centric Ethereum L2,” is a cryptographic method known as “garbled circuits.”Garbled circuits are a cryptographic primitive that enables two or more parties to evaluate an arbitrary Boolean circuit securely, without revealing any information beyond the output, all while using a constant number of communication rounds. This innovative approach enables the processing of transactions without exposing sensitive information and data, aligning with the platform’s commitment to privacy.Having originated in the 1980s, garbling protocols have evolved into a crucial element of privacy-preserving technologies, excelling in scenarios where confidential data needs to be part of a computation without revealing the information itself.Focusing on privacyCoti CEO Shahaf Bar-Geffen emphasized the significance of this privacy-oriented protocol, stating:“Sensitive data transmitted as public information on a blockchain is a bug, not a feature.”Bar-Geffen highlighted the protocol’s ability to prevent sensitive data from being exposed to competitors, partners and clients engaged in transactions on Coti’s chain. The CEO elaborated on how garbling protocols differentiate Coti v2 by facilitating transactions and smart contract executions where details remain private between involved parties.The Coti CEO emphasized the critical role of such privacy features in decentralized finance applications, where transaction confidentiality is as essential as transaction integrity. Coti claims that other platforms focusing solely on anonymity for privacy may face regulatory challenges and might not provide a compliant foundation for the broader ecosystem.Targeting specific use casesCoti envisions its protocol catering specifically to use cases demanding advanced privacy provisions in finance and healthcare. Currently designed for enterprises, Coti’s existing protocol enables the management of blockchain-based products such as custom-branded tokens, wallets, website integrations and fiat on-and-off ramps.In a blog post on Medium, the blockchain startup outlined that in addition to privacy, v2 will enable smart contracts, EVM compatibility and Solidity programming, alongside the features currently offered by v1. Notwithstanding these new features on the v2 product, the company confirmed to The Block that in respect of Coti’s original Cardano-based product, “Coti’s work with Cardano continues. We have a project built there called Djed, and that will continue to remain on Cardano.” Djed is an ADA-backed stablecoin pegged to the U.S. dollar.The anticipated release of Coti v2’s developer net in the second quarter of 2024 signals a move towards realizing the potential in advancing Ethereum’s privacy standards. As a layer-1 protocol, Coti presently contributes to Web3 applications by providing digital infrastructure, including tools for wallets, tokens and payment modules, with a total value locked of $31 million.The upcoming integration as a privacy-centric layer-2 positions Coti as a key player in enhancing Ethereum’s capabilities and fostering a more secure and confidential blockchain experience.

Seoul prosecutors charge eight suspects linked to crypto price manipulationEight individuals involved in a cryptocurrency fraud, which is separate from a murder case associated with the same token, have been formally charged and referred to court by public prosecutors in South Korea.The Joint Virtual Asset Crime Investigation Unit of the Seoul Southern Prosecutors’ Office has recently disclosed the arrest of two key figures in the scandal related to a cryptocurrency called Puriever (PURE). The unit apprehended the chief executive of the PURE issuer, referred to as “A” for anonymity, and a market manipulator. Both have been charged with fraud. In addition to these arrests, the prosecution has charged six other individuals–including an executive from a cryptocurrency consulting firm, anonymously named “C,” and a broker. These additional suspects have been charged but not arrested.Photo by Adam Śmigielski on Unsplash$16 million from over 6,000 victimsThe prosecution has accused the suspects involved in the PURE case of illicitly inflating the token’s price through deceptive disclosures and market manipulation during April and May 2021. This scheme reportedly enabled them to amass illegal profits totaling KRW 21 billion (close to $16 million) from approximately 6,100 victims. In March of this year, it came to light that the PURE was at the center of a series of criminal activities, including kidnapping and theft, which ultimately led to a murder in Gangnam, Seoul.The prosecution has uncovered that “A” and “C,” key figures in the PURE scandal, transferred 55.2 million PURE to a partner company under the guise of an initiative to reduce air pollution, as falsely stated in their disclosure. The suspects reportedly employed a skilled manipulator to inflate the token’s price artificially. Once the price peaked, they sold off the tokens, capitalizing on the artificially inflated value.Circulation supply manipulationThe case reveals a collective scheme orchestrated by a token issuer, a consulting entity, a broker, and an experienced market manipulator. A key tactic in their scheme involved locking their cryptocurrency wallet to artificially limit the token’s circulation supply. Furthermore, these fraudsters employed a bot to perform wash trading, which boosted the daily trading volume of the token. This strategy created a false impression of high demand and activity in the market.A representative from the prosecution emphasized that the cryptocurrency market is more susceptible to manipulation than the stock market. This vulnerability is attributed to the lack of a monitoring and supervision system in the crypto sector, despite its speculative nature. In response to these challenges, the prosecution has expressed a firm commitment to enhancing its crypto investigation capabilities with the goal of effectively combating criminal activities. These efforts are aimed at fostering a fair and transparent trading environment, safeguarding the integrity of the cryptocurrency market.
