Immediate response

In 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 deployment

The 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 investigation

Regarding 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.

Hackers spirit away over $300M in Bitcoin from DMM Bitcoin

Japanese crypto exchange DMM Bitcoin announced on Friday that over $300 million worth of Bitcoin was stolen from its primary wallet, marking one of the digital asset industry's largest hacks in recent years.Photo by Kanchanara on UnsplashHack confirmed without further detail"At approximately 1:26 p.m. on Friday, May 31, 2024, we detected an unauthorized leak of bitcoin from our wallet," the company stated, based on an English translation of its original statement in Japanese, which had been posted on the firm’s website. DMM Bitcoin is a subsidiary of DMM Group, which incorporates businesses covering a broad spectrum of activities including solar energy, gaming, 3D printers, FX, e-books and software. The company has, as yet, not provided any further detail relative to the manner in which the hack occurred. Notwithstanding that, DMM Bitcoin did confirm that measures have been taken to prevent any repeat of the hack. Furthermore, the company outlined that a full investigation into the hack is ongoing right now. Buy orders and leverage trades suspendedThe company has moved to reassure platform users that their digital assets are fully guaranteed. It stated: "Please rest assured that all of your bitcoin deposits will be fully guaranteed, as we will procure the equivalent amount of BTC that was leaked with support from our group companies."  The exchange has taken the decision to temporarily suspend a number of activities, including spot trading buy orders and the opening of leveraged trading positions. A temporary halt has been imposed on crypto withdrawals while Japanese yen withdrawals are permitted, albeit that the exchange suggests that service users may experience delays. Blockchain security sector responseIn light of the hack, a number of well-known blockchain security firms have been giving the matter their attention. Beosin, a blockchain security specialist, outlined that it is continuing to monitor the wallet addresses implicated in the hack, with a view towards tracing any further movement of the funds. Meanwhile, blockchain analysis firm Arkham Intelligence has offered a 1,000 ARKM token bounty to anyone who may provide information leading to the identification of the perpetrators of the hack. Blockchain analysis firm Chainalysis described the hack as “the 7th largest crypto hack ever.” The company has labeled the stolen funds within its products. Broader industry implications and historical contextThis hack is a significant blow to the industry, given that a hack on this scale has not occurred thus far in 2024 or at any point during 2023. The crypto industry has faced numerous significant breaches in the past. In 2022, a series of large-scale exploits targeted layer-1 blockchains, crypto exchanges and DeFi protocols. The largest hack amongst them implicated the BNB Chain (formerly Binance Smart Chain), which resulted in the loss of $566 million worth of BNB. The latest hack is second only (within Japan) in size relative to the 2018 hack of Coincheck, one of the country’s largest exchanges, when over $550 million worth of XEM was stolen. Japan was also host to the most infamous Bitcoin hack, that of the Mt. Gox exchange, whose bankruptcy administrators moved $9 billion worth of its remaining Bitcoin holdings on the blockchain in recent days for the first time in many years.

Bitdeer announces new mining chip and Q4 results

Bitdeer Technologies, led by Jihan Wu and based in Singapore, has unveiled the very latest development in the world of Bitcoin mining technology with the announcement of the successful testing of its proprietary Bitcoin mining chip, slated for integration into its forthcoming mining rig. In addition, the firm has followed up on March 4 with the publication of financial results for Q4 2023.Photo by Thought Catalog on UnsplashSealminer A1The company revealed on X that its inaugural crypto mining chip, known as the SEAL01, destined to drive the Sealminer A1 mining rig, was engineered utilizing four-nanometer process technology, a feat achieved in collaboration with a semiconductor fabricator. Bitdeer boasts that this chip exhibits a power efficiency ratio of 18.1 J/TH. At the heart of Bitdeer's latest achievement lies the SEAL01 chip, the culmination of years of dedicated research and development. By harnessing state-of-the-art technology and meticulous planning, Bitdeer aims to tackle the pressing challenges confronting Bitcoin miners, including skyrocketing operational costs and environmental implications. The company claims that the efficiency of the SEAL01 chip not only promises a shift towards more sustainable mining practices but also holds the potential to significantly reduce energy consumption, thereby bolstering profitability and return on investment for miners. "This powerful chip offers enhanced Bitcoin mining performance with minimized power consumption, leading to lower operating costs and a reduced environmental footprint for miners," Bitdeer affirmed in the X post. The firm stopped short of disclosing the launch timeline for its upcoming mining rig. On the financial front, Bitdeer disclosed its financial results for Q4 2023, on March 4. The company reported a total of 111,966,634 outstanding ordinary shares as of Dec. 31, 2023, including class A and class V ordinary shares. Additionally, Bitdeer revealed key operational metrics for Q4 2023, including total Bitcoin mined, power usage across its mining data centers, average cost of electricity and miner efficiency. Bitdeer's shares closed up 2.11% at $6.76 on Nasdaq on Friday, indicating a positive market response to its recent newly developed Bitcoin mining chip. However, trading outside regular hours, going into March 4, have seen the share price peak at $7.52, yet having retraced to $6.9 at the time of writing. That may indicate that investors are not particularly enthralled by the firm’s Q4 2023 results. Bitdeer emphasizes that the SEAL01 chip is engineered to meet the evolving demands of the cryptocurrency mining industry. As mining activities continue to gain traction and market dynamics evolve, the adaptability of hardware solutions becomes paramount. Bitdeer's strategic emphasis on innovation with the SEAL01 chip aims to pave the way for future advancements in cryptocurrency mining technology, ultimately fostering the growth and sustainability of the industry. Moreover, Bitdeer asserts that the newly developed chip enables it to optimize efficiency, stability and performance in anticipation of the upcoming Bitcoin halving event slated for April. Last month, the company’s founder Jihan Wu was installed as CEO, in a move that is understood to better position the company as it transitions to a growth phase.
