AndUs to implement ZK rollups on Its public permissionless blockchainAndUs, the South Korean developer of public permissionless blockchain Anduschain, announced on Wednesday (local time) that it is preparing to implement zero-knowledge (ZK) rollup technology into its blockchain to enhance scalability and security. ZK rollups are layer-2 scaling solutions that move transactions off-chain to increase throughput on the Ethereum mainnet.Photo by Shubham Dhage on UnsplashPerspective on ZK rollupsMany Korean projects are focused on developing various layer-2 solutions. Against this backdrop, Park Sung-jun, CEO of AndUs and a Ph.D. in cryptography, believes ZK rollups will eventually surpass the currently popular optimistic rollups as the mainstream technology. Although both ZK and optimistic rollups improve scalability by processing transactions off-chain, they differ in their approaches: ZK rollups rely on validity proofs, while optimistic rollups utilize fraud proofs.Introduction next yearHolding this belief, AndUs has formulated a ZK rollup implementation plan and has begun its development, aiming to introduce it by next year. Park commented that this upgrade will significantly improve the blockchain’s speed and expressed plans to offer the world’s lowest gas fees.AndUs claims that their DEB consensus algorithm focuses on fairness, enabling nodes to engage in mining without preconditions. Furthermore, Anduschain’s ZK rollups will be fully compatible with Ethereum virtual machines (EVMs), facilitating a seamless transition of decentralized applications (dApps). The cryptocurrency used on Anduschain is named DEB, and it is currently listed on cryptocurrency exchanges ProBit Global and MEXC, according to CoinMarketCap.AndUs has been participating in the Tech Incubator Program for Startups (TIPS) program, which is led by private investments under the guidance of the Korean Ministry of SMEs and Startups.

Akira ransomware, responsible for stealing $42 million from over 250 organizations across North America, Europe and Australia in just a year, is now targeting businesses in Singapore. In response, Singaporean authorities have issued a joint advisory warning local businesses about the increasing threat posed by a variant of this ransomware.Photo by Mike Enerio on UnsplashAlert follows complaintsThe alert follows multiple complaints from victims, prompting agencies like the Cyber Security Agency of Singapore (CSA), the Singapore Police Force (SPF) and the Personal Data Protection Commission (PDPC) to take action. These agencies emphasize the urgency of recognizing and combating this threat. How Akira operatesAkira affiliates employ various techniques to infiltrate a victim's network. These include exploiting known vulernabilities. For example, that could mean the targeting of services like Cisco virtual private networks (VPNs) that have been configured without multi-factor authentication (MFA). Another approach that the ransomware incorporates is attacking external-facing services such as the Remote Desktop Protocol (RDP) via brute force. Social engineering is another tool within its repertoire. This involves tricking victims into downloading malicious software or entering credentials on phishing websites. There is a marketplace for compromised credentials in the dark web. Akira also relies on such data, acquiring it from access brokers who sell network access.  Once inside a network, Akira affiliates often create new domain accounts to maintain persistent access, even after reboots. They use numerous tools to steal user credentials, escalate privileges and spread throughout the network. Detection and prevention measuresThe Singaporean advisory outlines several strategies for detecting, deterring and neutralizing Akira attacks. Authorities strongly advise against paying ransoms, on the basis that doing so does not guarantee data recovery or prevent future attacks. Authorities also warn that paying ransoms can encourage further attacks. The FBI has noted that Akira operators do not contact victims. Instead, they expect victims to initiate contact. Payment in BitcoinThe advisory outlines how Bitcoin is implicated in the ransomware scam. It states:”Ransom payments are requested in Bitcoin, which are directed to cryptocurrency wallet addresses specified by the affiliates. The TOR site (.onion) where victims contact the affiliates, contains stolen information and a list of the affected organisations.” It’s not the first time that Singaporean authorities have issued warnings that have implicated Bitcoin and crypto. In January, the CSA and SPF, in a joint advisory, suggested that people should use hardware wallets in an effort to guard against crypto-related malware and phishing attacks. A number of weeks prior to that, Singapore’s former Prime Minister, Lee Hsien Loong, took to Facebook to issue a warning with regard to a crypto scam that involved the use of deceptive content generated using artificial intelligence (AI). Mitigation techniquesBusinesses are being urged by the authorities to adopt best practices to mitigate the Akira ransomware threat. They suggest the implementation of a recovery plan alongside the use of multi-factor authentication (MFA) in order to secure data and the access to that data.  They also suggest filtering network traffic as it helps in identifying and blocking malicious activities. Meanwhile, disabling unused ports and hyperlinks curbs the risk further as it reduces the attack surface. Lastly, the authorities suggested the use of system-wide encryption to protect data even if it is accessed by unauthorized entities.

Busan Introduces Blockchain-Powered Cards for Multi-Children Families to Offer Social BenefitsBusan Metropolitan City, home to South Korea’s largest port, announced on October 20 (local time) a revision in its criteria for “multi-children families” who enjoy social welfare benefits and the launch of new blockchain-powered cards for these families. The city will reduce the requisite number of children in these families from three to two to extend benefits and encourage a higher fertility rate. To qualify for these benefits, at least one child in the family must be under the age of 19.Photo by Minku Kang on UnsplashBlockchain integrationStarting October 31, eligible families can access these benefits through “family love cards,” which will be available on BPASS, a mobile identification card app developed with blockchain technology. Some of these family love cards will be issued in collaboration with credit card company Shinhan Card.Diverse benefitsThe benefits include discounts at public facilities, restaurants, cram schools (commonly referred to as hagwons), and daycare centers. Specifically, public parking lots and sports facilities will offer services at half the usual rate. Meanwhile, other establishments targeting adolescents and women will either waive their fees entirely or provide reductions.On November 1, Busan will host the 16th annual Multi-Children Family Day ceremony at the City Hall’s international conference center. Having started this event in 2008, Busan stands out as the only metropolitan municipality to celebrate this occasion each year.Efforts to boost fertility rateThis year’s ceremony will highlight Busan’s initiatives to enhance support for multi-child families. The event will honor outstanding families and a childbirth-friendly organization, as well as districts and counties that have been exceptional in implementing childbirth promotion policies. Additionally, the occasion will be marked by special commemorative performances.Busan Mayor Park Heong-joon affirmed the city’s dedication to nurturing children alongside their families. He added that Busan will persistently refine and improve its childbirth policies to offer full support.
