Grayscale launches Zcash ETF, trading on NYSE Arca following key privacy vulnerability fix
Odaily News - Digital asset manager Grayscale's Zcash ETF began trading on NYSE Arca on Tuesday under the ticker ZCSH. The product is the world's first exchange-traded product offering spot exposure to Zcash, allowing investors to track ZEC prices through securities accounts without needing to directly purchase or store the token.ZCSH was formerly known as the Grayscale Zcash Trust, established in October 2017 through a private placement. Grayscale filed an application with the U.S. Securities and Exchange Commission in November 2025 to convert the trust into an ETF, with shareholders holding shares that track the fund's ZEC holdings rather than holding ZEC directly.In May of this year, security researcher Taylor Hornby, using Anthropic's Claude Opus 4.8, discovered a vulnerability in Zcash's Orchard shielded pool that had existed for four years, which could potentially allow attackers to mint counterfeit ZEC. Developers deployed an emergency patch on June 1, but due to privacy mechanisms, it was not possible to cryptographically confirm whether the vulnerability had been exploited.Zcash activated the Ironwood upgrade in July, replacing Orchard with a new shielded pool and introducing accounting rules that limit the amount of ZEC exiting the old shielded pool to no more than the amount entering. Grayscale stated it will monitor the adoption of the Ironwood upgrade, network security, exchange support, and regulatory conditions for privacy assets. (Decrypt)
Anthropic discloses three cybersecurity incidents involving Claude, where the model accessed real systems and obtained unauthorized permissions
Odaily News, July 30 – Anthropic released a report stating that during a review of cybersecurity assessment records, three incidents were discovered in which the Claude model accessed the internet in a third-party evaluation environment and further obtained unauthorized access to three real organizations' systems.Anthropic stated that the review covered 141,000 evaluation runs that could have potentially gained network access, and a total of three related incidents were found. All incidents occurred during Capture The Flag (CTF) cybersecurity tests, where the model was told the environment was a simulation with no internet access; however, due to configuration errors by the evaluation partner, the actual environment had internet connectivity.Among these, Claude Opus 4.7 accessed real company infrastructure during one test and obtained database permissions containing hundreds of production data records; Claude Mythos 5 built a malicious Python package and uploaded it to PyPI, resulting in the package being downloaded and run on 15 real systems; another internal research test model scanned approximately 9,000 targets and accessed a company's internet application through a public vulnerability.Anthropic stated that these incidents were not cases of the model actively seeking to escape or pursue its own goals, but rather the model mistakenly believed the real systems were within the test scope and continued executing the assigned cyberattack tasks. Notably, the newer internal research model stopped attacking after identifying that the targets might be real systems.Anthropic stated that these incidents primarily reflect issues with evaluation environment isolation and operational processes, rather than model alignment failures. The company has suspended related cybersecurity assessments, strengthened security controls in evaluation environments, continuously monitored test records, and will collaborate with third-party organizations to conduct further reviews.
Anthropic Discloses Claude Model Unauthorized Intrusion into Three Organizations' Systems
According to CNBC reports, Anthropic disclosed on July 30 that its Claude AI models accidentally breached the isolation environment and accessed the real internet during a cybersecurity assessment, gaining unauthorized access to the real systems of three different organizations through basic means such as accessing unauthenticated endpoints and exploiting weak passwords. The models involved include Opus 4.7, Mythos 5, and an internal research test model. The cause of the incident was a communication misunderstanding between Anthropic and third-party assessment partner Irregular, resulting in the models being told they were in a simulated environment without network access when they could actually still access the internet. Anthropic stated that this review was triggered by a similar Hugging Face intrusion incident disclosed by OpenAI last week; it has currently suspended all cybersecurity assessments and joined forces with independent AI assessment agency METR to launch further investigations, while calling on other AI labs to conduct similar reviews.
Polymarket probability of "Claude Fable 5 restored for US customers before July 1" rises to 73%, up 33% in 24H
Monitoring by Odaily Seer Prophet Channel shows that the probability of "Claude Fable 5 restored for US customers before July 1" on Polymarket has risen to 73%, up 33% in 24H.If Anthropic reopens Claude Fable 5 (or Claude Mythos, or a version confirmed to be the same model) to the US public before the specified date, this event will settle as "Yes"; otherwise, it will settle as "No". Qualifying methods of restoration include public beta or public waitlist; closed testing and private access do not count. Other models such as Haiku, Sonnet, and Opus are not included by default unless they are confirmed to be the same model as Claude Fable 5. Settlement will primarily be based on official announcements from Anthropic, supplemented by consensus reports from mainstream media.Due to export controls imposed by the US government on national security grounds, Anthropic urgently suspended global access to the Claude Fable 5 model just days after its release on June 9. Although the restrictions were primarily aimed at foreign users, due to the difficulty of real-time user identity screening, Anthropic ultimately closed access for all users, including those in the US, and switched requests to less capable models such as Opus 4.8. Anthropic is currently engaged in high-level discussions with the White House on issues including model capabilities and potential jailbreak risks. The company has publicly stated that the ban may have stemmed from a misunderstanding and is actively pushing to restore access.Odaily Seer Prophet Channel continues to monitor the prediction market, seeing changes before they are priced in.
Claude Announces Suspension of Fable 5 Access Due to U.S. Government Ban; Developers Urged to Switch Models Promptly
Claude announced that, due to U.S. government-related restrictions, access to the Fable 5 model will be suspended for all users. New sessions will default to the user’s configured default model or Opus 4.8; existing Fable 5 sessions will terminate immediately with an error. Additionally, API requests to Fable 5 on the Claude Platform will also return errors. Developers must promptly migrate their applications and integrations to other Claude models.
Bitgo CEO deposits ~$6.3M in BTC, challenges Claude to move the funds
: Bitgo CEO Mike Belshe deposited 100 BTC into a public Bitcoin address on August 1, worth approximately $6.3 million at the time, and invited Anthropic's Claude model to attempt to move the funds out of the address. On-chain records show the wallet received the funds on July 31, and the balance had not been transferred out as of August 2. Anthropic previously disclosed that during 141,006 cybersecurity assessment runs, 3 incidents were found, with 6 evaluation sessions involving 3 models inadvertently interacting with real organizational systems. The models involved include Claude Opus 4.7, Claude Mythos 5, and an unreleased internal research model. The cause was a configuration error by third-party testing partner Irregular, which led to the test environment being connected to the internet. Anthropic stated that Claude Opus 4.7, during one evaluation, located a real website with the same name as a simulated company, exploited weak passwords and exposed services to recover infrastructure credentials, and accessed a production database containing hundreds of records. The company said the model was attempting to complete assigned tasks, not actively breaking constraints or pursuing independent goals. Belshe's challenge involves Bitgo's institutional custody platform, which uses multi-signature or multi-party computation technology to distribute signing authority across multiple independent keys. As of August 2, Anthropic had not publicly responded to the challenge.
Immunefi CEO claims AI models lead to surge in crypto security vulnerabilities
Odaily, Mitchell Amador, CEO of bug bounty platform Immunefi, stated at the WAIB Summit that new AI models such as Claude Opus 4.8 and ChatGPT 5.5 are shifting the balance of cybersecurity offense and defense in favor of attackers, leading to a resurgence in crypto hacks in 2026. Data from DefiLlama shows that in April 2026, illicit actors stole over $634 million from crypto platforms, the highest monthly total since the Bybit hack in February 2025 drove losses of approximately $1.4 billion.Amador stated that the crypto industry is in a critical survival period for the next three to four years until security teams leverage similar AI models to build codebases that attackers cannot breach; if the industry adopts more crowd-sourced security solutions, this timeline could be shortened to within two years. The latest Claude Mythos model, Fable 5, from AI company Anthropic, previously raised concerns about accelerating the ability to exploit crypto vulnerabilities.Anthropic stated that Fable 5 has safeguards in place that will redirect topics related to cybersecurity and similar fields to Claude Opus 4.8. On April 19, an attacker transferred approximately 116,500 restaked Ethereum (rsETH) from Kelp DAO's LayerZero-based rsETH bridge, valued at around $290 million to $293 million at the time. Cross-chain protocol LayerZero stated that the 1/1 decentralized verification network configuration of Kelp DAO relied on a single verification path for processing cross-chain messages, creating a single point of failure.
