Policy & Regulation·May 15, 2023, 6:52 AM

In a move aimed at advancing central bank digital currency (CBDC) technology, the Bank of Korea (BOK) signed a memorandum of understanding (MoU) with Samsung Electronics on Monday, according to a press release. The agreement was sealed during a signing ceremony attended by Lee Seung-heon, BOK’s Senior Deputy Governor, and Choi Won-joon, Executive Vice President and Head of Development in the Mobile Experience (MX) Division at Samsung Electronics.

Under the terms of the MoU, both parties have committed to ongoing research on CBDC issued by the Bank of Korea, with a specific focus on collaboration in the offline payment sector. Samsung Electronics had previously participated in the second phase of the CBDC simulation study conducted by the BOK last year.

CBDC without Internet

The company’s efforts have led to the development of an offline CBDC technology that facilitates transfers and payments via near-field communication (NFC) between devices without requiring an internet connection. These transactions are conducted within the embedded secure element (eSE) chip of Samsung Electronics’ mobile devices, which holds one of the highest levels of security certification, CC EAL 6+.

The Evaluation Assurance Level (EAL) is a numeric grading system that measures the security level of tech products and systems according to the Common Criteria (CC) security standard. It ranges from EAL0 to EAL7, with EAL7 representing the highest level of security.

Leveraging this technology, the BOK and Samsung will continue their joint research to enhance security in offline payments using Samsung Galaxy smartphones and watches. Additionally, they aim to provide support for stable payments in situations where network connectivity is disrupted, such as during disasters.

 

Growing interest in CBDCs

Given the global interest in CBDCs, with central banks worldwide exploring their potential, the research collaboration between the BOK and Samsung assumes great significance. The results of this partnership will guide further cooperative efforts to develop the international CBDC ecosystem.

BOK Senior Deputy Governor Lee Seung-heon emphasized the significance of the joint achievement, expressing optimism that the partnership would keep Korea at the forefront of offline CBDC technology.

Samsung’s Executive Vice President Choi Won-joon underscored that the company’s collaboration with the Korean central bank allowed Samsung to utilize its advanced security technology in digital currency. He expected their combined efforts would considerably contribute to the global development of CBDC technology.

Atomic Wallet Hacker Uses Lazarus Crypto Mixer

Atomic Wallet Hacker Uses Lazarus Crypto MixerThe stolen cryptocurrency from the recent $35 million hack of Atomic Wallet is already being moved to a crypto mixer favored by North Korea’s notorious cyber-hacking group.Photo by Micha Brändli on UnsplashSinbad.ioAccording to UK-based crypto compliance analysis firm Elliptic, the funds have made their way to a crypto mixer used by Lazarus Group, a notorious hacker group that focuses on crypto heists which is believed to have direct ties with the North Korean government.On June 5, Elliptic’s Investigations Team revealed that it had traced the funds from the Atomic Wallet hack to the crypto mixer Sinbad.io. Lazarus had previously used the mixer to launder over $100 million in stolen crypto assets.While the exact amount sent to the mixer was not specified, Elliptic noted that the stolen funds were being exchanged for Bitcoin before undergoing obfuscation through the mixer. Additionally, Elliptic reported that Sinbad.io is likely a rebranded version of Blender.io, another mixer extensively used to launder funds by the Lazarus Group. Blender.io has been sanctioned by the US Treasury.Atomic Wallet hackThe hack of several user accounts on Atomic Wallet occurred on June 3, resulting in losses of up to $35 million. News of the issue broke with the following tweet from the project team (which has subsequently been deleted): “We have received reports of wallets being compromised. We are doing all we can to investigate and analyze the situation. As we have more information, we will share it accordingly.”In a follow-up tweet the next day, the team confirmed that it was investigating the matter with the assistance of a number of “leading security companies.”However, Atomic Wallet later downplayed the incident, stating that less than 1% of its monthly active users were affected. The project team was castigated by users for trying to present the hack as a minor incident. One user took to Twitter to call out the Atomic Wallet team for “having the nerve to come to the networks and say that only 1% of wallets were affected.”The Atomic Wallet project is based out of Tallinn, Estonia, having been founded in 2017. It claims to provide a non-custodial decentralized multi-currency crypto wallet. The product supports over fifty coins and two hundred tokens. It also offers atomic swaps between digital assets, while also supporting integrations with instant exchanges such as Changelly, ShapeShift, and others.Roland Säde, the Chief Marketing Officer of Atomic Wallet, assured users that the team is working tirelessly to recover the stolen funds. He emphasized the need to complete the investigation to develop a concrete plan.Despite the ongoing efforts, Säde urged victims to track the illicit transfers and report them to popular crypto exchanges. By doing so, it was thought that may hinder the scammers from exchanging the funds.Crypto hacking menaceLazarus Group hackers have been the bane of the crypto space in recent years. Elliptic released a report last month that identified Japan as having been the country most adversely affected by the North Korean hackers. It’s understood that the estimated $721 million in stolen crypto from Japan-based entities amounts to nearly nine times the value of North Korea’s exports based on 2021 data.While Atomic Wallet is directly reporting the incidents, Säde believes that having more individuals monitoring the hackers’ activities will make it more challenging for them to move the funds undetected. Unfortunately, Elliptic’s recent findings suggest that for many victims, it may already be too late to prevent further misuse of their stolen cryptocurrency.

Korea Insurance Institute eyes Bitcoin treasury move

The Korea Insurance Institute (KII), an incorporated association that trains insurance professionals, has initiated a phased process to become South Korea's first institution to hold Bitcoin (BTC), while the national tax agency is moving to enlist private crypto custodians following a recent security breach, local media reported.Photo by Kanchanara on UnsplashThe non-profit KII has established a digital asset review committee to establish internal regulations for managing cryptocurrencies as institutional holdings, Yonhap Infomax reported. The move is designed to prepare for an upcoming legal framework governing Korean won-backed stablecoins. While retail crypto investment is legal in South Korea, corporate and institutional participation remains tightly restricted. However, the institute noted that KII could still acquire digital assets through an existing regulatory channel, as non-profit organizations are permitted to hold crypto wallets. The newly established committee will draft guidelines covering crypto operations, risk management, accounting and tax standards, and internal controls. Once the regulatory framework is in place, KII plans to spend its stablecoins to acquire BTC and Ethereum (ETH). Ha Tae-keung, president of KII, said the launch of the digital asset review committee could mark a new milestone for innovation in asset management within the finance and insurance industry. He added that the institute would seek to serve as a working model for a new financial system shaped by artificial intelligence and digital assets. Tax agency seeks custodians to manage cryptoIn parallel government developments, the National Tax Service (NTS) is pushing to select custody providers to manage confiscated digital assets as early as the first half of this year, according to a ZDNet Korea report.  The policy shift follows a security breach late last month, when confiscated cryptocurrency was stolen on two occasions after a mnemonic seed phrase was inadvertently disclosed in an NTS press release detailing on-site asset seizures from tax evaders. To prevent future breaches, an NTS task force launched earlier this month is developing comprehensive manuals for the confiscation, storage, and sale of digital assets. The group is also developing criteria for selecting custodians, including security standards, company size, and required insurance coverage under the Virtual Asset User Protection Act. A source familiar with the matter told ZDNet Korea that the NTS is assessing security standards and other key criteria ahead of selecting a custodian, adding that not all providers meet the strict requirements for government appointment. The NTS task force is also preparing to set up a dedicated digital assets division to oversee crypto issues, with final details to be determined in consultation with the Ministry of the Interior and Safety.
