first_img The U.S. Department of Justice and CrowdStrike teamed up to dismantle the Sality botnet, which had been operating for over 20 years

According to Decrypt, CrowdStrike and the U.S. Department of Justice announced on Tuesday that they have dismantled the Sality peer-to-peer botnet, which has been active since 2003.This botnet primarily hijacked cryptocurrency payments through the EggJagger malware over the past eight years, which monitored the cryptocurrency wallet addresses in victims' clipboards and replaced them with the operator's own address, causing victims to send funds to strangers.CrowdStrike estimates that the operator has stolen at least 12.1 million rubles (approximately $150,000) solely through the EggJagger payload. Most of the stolen cryptocurrency has not been spent, and CrowdStrike assesses that these unspent assets were worth about 147 million rubles (nominally around $1.35 million) at their peak in January 2025. The reason Sality has survived to this day is that it does not have a central server that can be seized; infected machines communicate directly with each other.This multinational operation involved the United States, Bulgaria, Hungary, and Romania. The U.S. Department of Justice, FBI, and Defense Criminal Investigative Service seized Sality-related domains within the United States, and police from multiple European countries also seized other domains.CrowdStrike isolated more than 15,000 infected machines to its controlled honeypot by exploiting its architectural vulnerabilities. The operator has been tracked as SALTY SPIDER, which launched a denial-of-service attack against the Russian cryptocurrency exchange AvanChange in September 2023.

first_img XRP ETF saw a net inflow of 170 million USD for 11 consecutive days, with Goldman Sachs ranking first among institutional holders

The US spot XRP ETF has recorded net inflows for 11 consecutive trading days, attracting approximately $170 million in funds during this period. Since its launch in November last year, the cumulative net inflow of these funds has reached about $1.68 billion. As of Wednesday morning, the trading price of XRP was around $1.33, down from about $1.45 on August 27, but still higher than the $1 level in mid-August.According to the disclosures in the 13F filings, Goldman Sachs is the largest institutional holder of the XRP ETF, holding approximately $87.4 million, while Jane Street and Millennium Management hold $16.6 million and $16.2 million, respectively. Investment advisors are the largest category of holders, accounting for about $120 million of the disclosed $183 million, while hedge funds hold about $25 million, and brokers and banks hold approximately $17 million and $14 million, respectively.However, institutional holdings and fund inflows measure different dimensions: the 13F filings reflect the holdings as of June 30, while the continuous inflows record new funds from the end of August to early September. These data only reflect the total holdings of the ETF and not the complete exposure of investors to XRP; institutions like Goldman Sachs may hedge part of the price risk through futures or other instruments. The next round of 13F filings will be released in November.

first_img TSMC temporarily uses micro-bump packaging for HBM and requires the development of a 5μm solution

According to sources in the materials industry, on September 2, TSMC is expected to continue using traditional micro-bump technology rather than hybrid bonding in the short term for connecting high-bandwidth memory (HBM) with AI accelerators in advanced packaging. Considering the development cycle of related materials, finer pitch micro-bumps are expected to be used until the later stages of HBM4 and the early stages of HBM5. TSMC has requested its materials and equipment partners to develop bonding and underfill solutions for approximately 5-micron bumps, with suppliers from South Korea and Japan beginning development, and mass production of 5μm bumps expected to start in the second half of 2028.Currently, the bump height of the third-generation extended HBM, namely HBM3E, is about 15-25μm, while HBM4 is close to about 10μm. Japanese material suppliers have previously stated that it is difficult to guarantee quality below 15μm. The reduction and refinement of bumps are due to the height limitations of HBM cubes and the demand for higher interconnection density. JEDEC specifies that the maximum height for HBM stacks is 775μm. In TSMC's advanced CoWoS packaging, the HBM stacks assembled by GPU and memory suppliers are mounted onto the silicon interposer via micro-bumps, with the 16-layer DRAM chip stacks completed within HBM packaging by SK hynix and Samsung Electronics.The first and second generations of HBM used larger solder bumps, while micro-bumps became mainstream around the HBM3 generation. SK hynix uses the MR-MUF process, while Samsung Electronics uses TC-NCF. Hybrid bonding allows for thinner and denser interconnections through direct bonding of copper pads; TSMC has utilized this on its SoIC platform for logic chip stacking, but HBM still connects to the interposer using micro-bumps.

first_img G20 finance ministers commit to establishing a clear path for digital asset innovation

After a two-day meeting in Asheville, North Carolina, G20 finance ministers and central bank governors issued a statement committing to developing clearer rules for digital assets to promote financial innovation. The statement acknowledges that digital financial innovations, including digital assets, can support "broad economic growth" and play a key role in driving private sector innovation.The statement reads: "We are committed to advancing a responsible and effective regulatory and supervisory framework to maintain financial stability, support economic growth, and establish a clear path for sound digital finance and digital asset innovation, while taking into account cross-border opportunities and challenges." G20 officials expressed anticipation for the upcoming findings from the Financial Stability Board regarding the cross-border impacts of global stablecoin arrangements, as well as related reports on stablecoin data sources, availability, and potential challenges.They also reiterated their commitment to strengthening the G20 roadmap for cross-border payments and called on member countries to extend the operating hours of large payment systems. Several G20 member countries, including the United States, the European Union, and Japan, have reviewed the potential of digital assets or stablecoins to enhance the efficiency and accessibility of existing financial and payment systems and have established relevant frameworks.

Analysis: Bitcoin is experiencing its first hash rate bear market, highlighting the opportunities for large mining companies to scale up mining

Rapha Zagury, CEO of Twenty One Capital and founder of Elektron Energy, stated during his speech at Bitcoin Asia 2026 that the Bitcoin network is experiencing its first-ever bear market in hashrate. The hashrate of the Bitcoin network was close to 1.3 ZH/s at the end of last year, but has since been slowly declining, with the duration of this decline from the historical peak now setting a record. Zagury believes that Bitcoin mining is not simply a "good business" or "bad business"; it largely depends on where the mining company stands on the cost curve. Mining companies with lower energy costs and higher machine efficiency can maintain higher profit margins, while those with high energy costs and low equipment efficiency may be forced to shut down.Currently, while the Bitcoin hashrate price has improved compared to before, it is still at a relatively low level when measured against historical standards. When the price of Bitcoin rises faster than the growth of the network's hashrate, mining is more likely to outperform BTC. For companies, he believes that the best risk-adjusted allocation is not simply choosing to "buy BTC" or "mine," but rather a combination of both; however, if only $1 can be allocated, he suggests prioritizing the purchase of BTC. Regarding energy issues, Zagury stated that energy consumption itself does not imply waste; energy is the foundation of economic development and human progress. He believes that one of the greatest characteristics of Bitcoin mining is its highly flexible load, as mining machines can quickly turn on and off based on energy supply, thus helping the grid absorb idle or surplus electricity and enhancing grid stability to some extent. Additionally, he believes that Bitcoin mining is generating "option value" that was not previously apparent, including aspects such as energy utilization, market share, proximity to the Bitcoin protocol, and infrastructure. With the growing demand for AI and high-performance computing (HPC), the existing energy and data center infrastructure of mining companies may also gain additional application scenarios such as AI computing power. Currently, among large publicly listed mining companies, there are fewer and fewer that can continue large-scale Bitcoin mining, and the industry is at a critical stage where the energy revolution intersects with the Bitcoin revolution.

first_img Core DAO Emergency Hard Fork Due to Validators Over-Claiming Rewards Plan

Core DAO is coordinating an emergency hard fork due to some validators receiving CORE rewards that exceeded the protocol's expected issuance. Core stated in an update that the situation has been brought under control, and "malicious validators" can no longer claim excess rewards. This fork is a forward upgrade and will not roll back the network or revoke any confirmed transactions.Previously, Core indicated in a status update on Monday that the rewards accumulated by a small number of validators were significantly higher than the protocol's expected issuance. The incident was limited to the reward distribution phase, user assets remain secure, and they promised to release a technical review report. Following the incident, several exchanges restricted CORE transfers: Coinbase suspended deposits and withdrawals on the Core network, Bithumb and Coinone suspended deposits and withdrawals, Bitget suspended deposits and withdrawals citing wallet maintenance, and LBank suspended deposits at the request of the project party.Core has not disclosed the amount of excess issued CORE, the duration of the activity, or whether additional tokens have entered circulation, nor have they provided details on the vulnerability that allowed validators to receive rewards. Cointelegraph reached out to Core for further information but had not received a response by the time of publication.
