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.

Korean health management app leverages blockchain for iris-based solutionsIRIS, a blockchain foundation focused on healthcare, announced on Wednesday (local time) the launch of a health management app developed in collaboration with Hongbog, a South Korean provider of iris-based biometric systems. This app offers services customized to each user’s health status and lifestyle.Photo by Kalea Jerielle on UnsplashIridology-based health analysisUnlike other healthcare platforms that primarily focus on exercises, IRIS’ app offers long-term and periodic health trend analysis reports through iris photography. This approach is based on “iridology,” a concept used in traditional Korean medicine, and the app also recommends visits to specialized healthcare providers based on its findings.The app instantly analyzes a user’s biometric information through artificial intelligence once a picture of their eyes is captured with a smartphone camera. Within 15 seconds, users can view their results, based on which the app recommends personalized exercises and nutrients.This platform serves both personal disease management and prevention, and can also be utilized by public health centers for monitoring the health of local residents. Presently, it provides five health ratings for cholesterol, stress levels, and four specific organs: the brain, lungs, liver and kidneys. Future updates will optionally include information on an additional 15 organs, such as the heart, bronchi, pancreas and stomach.Blockchain-powered privacy protectionA representative from IRIS conveyed that their goal in an aging society is to assist customers in preventing serious illnesses and promoting longer, healthier lives. They emphasized that the app enables regular measurement of health indicators, aiding in disease prevention and management. The representative also mentioned that by storing sensitive healthcare information on the blockchain, the service eliminates the risk of personal data leaks.

The Royal Government of Bhutan has moved $66 million in Bitcoin (BTC) to global crypto exchange Binance. That’s according to blockchain data analytics firm Arkham Intelligence, outlining that the assets were moved to Binance over two separate transactions. The firm took to the X social media platform on Oct. 29 to highlight the digital asset transfer. In its X post, the firm wrote:”Crypto wallets belonging to the Royal Government of Bhutan moved $66.55M BTC to Binance this morning. The last time they deposited to exchanges was 4 months ago, at the start of July.”Photo by Moose Photos on PexelsSell-off concernsSome crypto community commentators have expressed concern of a sell-off given that the nation nestled in the Himalayas still has a holding of 12,456 Bitcoin, worth in the region of $900 million. The transfer was made on a day in which Bitcoin reached a unit price in excess of $73,000.  Arkham outlined that geographical data suggests that Bhutan’s Bitcoin mines remain active. On Oct. 29, they had accumulated $600,000 worth of Bitcoin mining rewards on-chain.  In this latest market activity, the Bhutanese began selling when the Bitcoin unit price had exceeded $70,000. As Bitcoin reaches towards new all-time-high pricing, Bitcoin whales often take profits. Mining Bitcoin since $5KIt emerged in 2023 that Bhutan had been quietly mining Bitcoin over the course of a number of years, since the leading digital asset had a unit price of around $5,000. The commercial activity has been enabled via Druk Holding and Investments (DHI), the commercial arm of the Royal Government of Bhutan. The Asian nation has ample hydroelectricity resources, being the only carbon-negative country in the world. Consequently, all its Bitcoin mining is carried out using hydro. While mining activity had been ongoing for a number of years and had largely gone unnoticed by the industry, an entanglement between DHI and failed crypto lenders BlockFi and Celsius brought more attention onto the Bhutanese holding company’s activities relative to crypto.  LawsuitsDHI was sued by BlockFi with the action subsequently voluntarily dismissed. In the case of Celsius it withdrew around $65 million from the platform prior to Celsius declaring bankruptcy. As a consequence, Celsius is currently suing DHI to claw back the funds that were removed from the platform. In 2023 Singaporean Bitcoin mining firm Bitdeer entered into a partnership with DHI with a view towards jointly developing green digital asset mining operation within the Kingdom of Bhutan. At the time, DHI CEO Ujjwal Deep Dahal said that the partnership formed part of an overall strategy to ensure that Bhutan took its place at the forefront of global innovation. Arkham Intelligence outlined on X that in H2 2023, Bhutan’s Bitcoin mining operations were producing in the region of 26 Bitcoin per day, or 780 Bitcoin per month. However, over the past three months, that mining rate has decreased to 8.6 BTC per day or 260 BTC per month. Arkham suggests that the Bitcoin halving, together with the increase in the Bitcoin hashrate, explains the reduced output, although it speculated that some unknown issue with Bitcoin mining rigs may also be a contributing factor.
