Hacking Attempts on Upbit Reach 160,000 in First Half of the YearThere have been approximately 160,000 hacking attempts on Upbit, Korea’s largest cryptocurrency exchange, in the first half of this year alone, according to a report submitted by Upbit’s operator Dunamu to lawmaker Park Sung-joong of the National Assembly’s Science, ICT, Broadcasting, and Communications Committee.“Cryptocurrency hacking incidents are increasing both domestically and internationally, and hacking attacks on exchanges such as Upbit, which have daily trading volumes exceeding KRW 2 trillion, are a serious issue,” Park said.Photo by Clint Patterson on UnsplashAn uptick in hacking attemptsThe data revealed that the number of cyber breach attempts in the first half of the year totaled 159,061–2.17 times higher than the number of attempts in the first half of last year, which stood at 73,249.Hacking attempts on Upbit have been steadily increasing in recent years, from 8,356 in the second half of 2020 to 34,687 and 63,912 in the first and second half of 2021, respectively. In the first half of last year, there were 73,249, and 87,242 in the second half. Notably, the exchange suffered losses of approximately KRW 58 billion (approximately $43 million) from a hacking attack in 2019.Ramping up securitySubsequently, Dunamu has taken action to enhance security by managing over 70% of its assets in cold wallets and operating hot wallets in a distributed structure instead of a singular one. Hot wallets refer to online crypto wallets, whereas cold wallets are crypto wallets that are offline and disconnected from the internet. Hot wallets offer the advantage of direct deposits and withdrawals, but they have weaker security levels — most known exchange hacks have thus occurred through this medium. On the other hand, cold wallets store private keys on offline sources like external hard drives and portable storage devices, making real-time trading difficult but providing better security and stability.“We have taken various preventive measures since the hacking incident in 2019, such as operating hot wallets in a distributed manner. There have not been any successful cyber breaches to date,” Upbit said.Regarding the role of the Ministry of Science and ICT in managing and overseeing crypto hacking incidents, Park pointed out that this still remains ambiguous. “The Ministry should conduct large-scale white-hat hacking tests and security assessments for crypto exchanges that are frequently faced with hacking attempts, as well as for hospitals and subway systems that manage large amounts of personal information,” he said.

CoinEx Reveals Insights Into Recent Platform HackHong Kong crypto exchange CoinEx has issued a further update relative to the security breach that occurred on the platform last week resulting in one of the exchange’s hot wallets being compromised.Photo by FLY:D on UnsplashImmediate responseIn the immediate aftermath of the $70 million hack, CoinEx took action to safeguard user assets and initiate an investigation into the incident. It suspended all deposit and withdrawal services and executed an emergency shutdown of the hot wallet server. Following this, the company securely moved the remaining assets to cold storage, commencing the process of reconstructing and deploying a new wallet architecture.The firm also engaged in an investigation, spearheaded by its wallet and security teams, to ascertain the extent of the breach. Moreover, CoinEx claims to have proactively reached out to fellow exchanges to freeze any assets related to the attack.Haipo Yang, the Founder and CEO of CoinEx, conveyed his apologies to affected users through his personal X (formerly Twitter) account. He emphasized the team’s commitment to restoring services promptly and reassured users that their funds will remain secure.Following up on that commitment, CoinEx published an update on the hot wallet hack on September 15 to address these concerns individually.New wallet deploymentThe exchange expects to finalize wallet upgrades within the upcoming week, after which withdrawals will gradually be phased in, subject to security evaluations. The CoinEx team is currently working on developing and deploying an entirely new and robust wallet system capable of managing activities across 211 chains and 737 assets.The firm has outlined that each of its product lines operates independently, featuring its own risk control system. Consequently, the security incident that occurred on CoinEx will not affect the integrity of its other product lines.In its most recent update on Tuesday, the Hong Kong crypto exchange confirmed that 80% of its wallet system has now been reconstructed. It added that it has initiated preparations to enable the withdrawal system on the platform. It stated:”Details about the resumption of withdrawals, including specific dates, times, and arrangements, will be announced on the CoinEx website. Please stay updated on our announcements for the latest information.”Ongoing investigationRegarding the identity of the attacker, CoinEx has confirmed that the matter is currently under investigation. While some security firms have made attribution claims, the company is focusing primarily on deploying the new wallet architecture, restoring affected users and functionalities, and enhancing overall security.At the same time, the company has initiated communications with the hackers in a bid to proactively seek a mutually agreeable resolution. While the incident implicates the loss of a substantial amount of funds, the firm maintains that in the context of the overall business, the sum represents only a small percentage of total assets under its management.Exchange security remains a major challenge in the crypto sector, with hacks happening on an ongoing basis. Last week, Seychelles-headquartered peer-to-peer crypto platform Remitano acknowledged a $2.7 million hack. At the beginning of September, crypto gambling platform Stake was reported to have suffered a $41 million hack.

In less than a year since Hong Kong regulators gave the green light to crypto exchanges, there's been a noticeable surge of interest among traditional financial institutions and brokerages eager to secure their digital asset licenses for trading.Photo by Florian Wehde on UnsplashTiger BrokersTiger Brokers, a Beijing-headquartered one-stop trading brokerage with nine million international customers, offers one such example. The firm upgraded its Type 1 Hong Kong Securities & Futures Commission (SFC) license in January to include crypto trading for professional investors and financial institutions based in Hong Kong. The move followed an uptick in interest from mainland China-based firms in Q4, 2023.In a recent interview with Cointelegraph, John Fei Zeng, the CFO and director of Tiger Brokers, revealed that the firm currently boasts 865,500 funded accounts in Hong Kong, managing $18.9 billion in assets. Zeng stated: "Residents of Hong Kong will be able to trade virtual assets such as Bitcoin and Ethereum alongside stocks, options, futures, funds, and ETFs [Through Tiger Trade]." He explained that as part of the firm's expansion plans, additional digital assets will be evaluated. HKMA guidance on crypto custodyAs a testament to the regulatory clarity that has attracted firms like Tiger Brokers, on Tuesday Hong Kong's central bank issued guidance for authorized institutions interested in offering custody services for digital assets. The Hong Kong Monetary Authority (HKMA) outlined comprehensive risk assessment procedures and emphasized the importance of robust policies, oversight, and resource allocation to manage custodial activities effectively. Notably, the HKMA's guidance seeks to address concerns stemming from recent industry mishaps, including the collapse of FTX, Terra and Three Arrows Capital (3AC), by mandating stringent safeguards to protect clients' digital assets from theft, fraud or misappropriation. Key requirements include independent systems audits, secure storage practices and transparent record-keeping, underscoring the regulator's commitment to fostering trust and stability in the digital asset ecosystem. Victory SecuritiesIn a similar move to that of Tiger Brokers, Victory Securities, another Hong Kong brokerage, secured a license from the SFC last November to offer crypto trading services for retail investors. The company reported a significant surge in virtual asset transactions and new customer acquisitions, prompting plans to introduce trading discounts to incentivize compliant and safe virtual asset trading services. Moreover, OSL, a licensed Hong Kong crypto exchange, joined forces with Interactive Brokers in November 2023, enabling the latter to offer bitcoin and ether trading to retail investors through its platform. Further underscoring the evolving regulatory landscape, crypto exchange Bybit submitted a retail trading license application in Hong Kong, indicative of the sector's continued growth and maturity. Nevertheless, navigating the regulatory framework isn't without its challenges. Web3 firms eyeing Hong Kong may need to invest up to $25 million in corporate infrastructure and compliance to secure licensing approval, reflecting the stringent requirements imposed by regulators. As Hong Kong continues to refine its regulatory framework and enhance investor protections, the stage is set for further collaboration between traditional financial institutions and emerging crypto players within the Chinese autonomous territory.
