TechFlow’s Aug. 19 market roundup put artificial intelligence, crypto, semiconductors, U.S. equities and macro headlines into one tape. The standout AI update came from Anthropic, whose annualized revenue reportedly doubled to $11.6 billion, overtaking OpenAI for the first time, with Claude Code cited as the main growth driver. Another Claude-related thread drew attention at the same time: users shared a case in which Claude wrote a macOS driver for a HP printer that only officially supports Windows, while Reddit users were also discussing another apparent Claude outage. In crypto, spot Bitcoin ETFs added $189 million in a single day, bringing August net inflows close to $1 billion before the month has ended. Cointelegraph also reported that BlackRock believes Bitcoin has largely worked off the speculative excess that previously led to a 50% drawdown. Ripple raised $275 million to target U.S. prime brokerage demand, while Arthur Hayes became CEO of Flop Labs, a project expected to hold an airdrop in the fourth quarter. Outside crypto, semiconductor selling intensified, with SOXL down about 14% and South Korea’s KOSPI triggering a sidecar halt after early losses deepened. In China’s A-share market, Unitree closed up 460% after surging as much as 629% intraday.

The Dutch National Cyber Security Centre (NCSC) has warned that a recently patched authentication flaw in Apple’s macOS Screen Sharing component is already being exploited in the wild, according to The Hacker News. The bug, tracked as CVE-2026-65400 and rated 9.8 on the CVSS scale, allowed attackers to access internet-exposed Macs listening on port 5900 without valid credentials and deploy Monero mining malware. Apple issued emergency fixes on Aug. 6 through macOS Tahoe 26.6.1, Sequoia 15.7.9 and Sonoma 14.8.9, saying the patch strengthened credential validation by improving state management. The NCSC said it confirmed multiple attacks in which intruders gained root privileges and installed mining software. Security researcher @osxreverser also disclosed another pre-authentication flaw in the same component, likewise fixed in version 26.6, which could be exploited with only a target IP address and no username. Calif said researchers used AI to build working exploits for the two bugs in just four hours, highlighting how AI is shortening the time between vulnerability discovery and exploit development. Users were advised to update immediately or disable Screen Sharing if patching is not possible.

OpenAI has rolled out Computer History in the ChatGPT desktop app for Mac, introducing a system that logs keyboard activity, mouse clicks, app switches, and other interaction events to create searchable memory files for ChatGPT and Codex. The feature launched on August 13 and is turned off by default, requiring users to enable it manually. It is being made available to ChatGPT Pro, Business, and Enterprise subscribers, with the European Union, the UK, and Switzerland set to follow in the coming weeks. Unlike earlier approaches based on screenshots, Computer History relies on macOS accessibility APIs to capture interaction events and convert them into Markdown memory files stored locally on the user’s device. OpenAI says the raw event stream is processed on its servers and deleted within 48 hours. Still, the company also acknowledges that the resulting local memory files are not encrypted and may contain sensitive information accessible to other software running under the same macOS user account. OpenAI further says the feature increases exposure to prompt injection attacks because it can ingest a much broader range of content than a normal chat window. The report also notes that summarizing activity consumes tokens, adding to user costs. Critics have compared the system to Microsoft Recall, though OpenAI’s design differs in that some data is sent to company servers rather than being handled entirely on-device.

A dense 24-hour news cycle brought fresh filings, earnings, market calls and regulatory signals across crypto and adjacent tech markets. Fidelity filed an amended registration statement with the U.S. Securities and Exchange Commission on Aug. 11 to add ETH staking to its spot Ethereum ETF, the Fidelity Ethereum Fund (FETH). Under normal conditions, the fund said it could stake as much as 100% of the ETH it holds, with no minimum staking threshold, and its investment objective would change to include staking rewards if approved. Elsewhere, some existing Anthropic investors said the AI company could be valued at more than $2 trillion if it goes public as early as October, with one investor putting the upside case at $3 trillion based on a roughly 30x revenue multiple. The estimates remain investor forecasts, and several investors said Anthropic management has not set an IPO valuation target. The session also featured quarterly updates from Bullish, BitGo and Securitize, new SEC steps around tokenized fund operations and tokenized equities, ETF flow data for Bitcoin and Ethereum products, and a series of policy, infrastructure and security developments spanning Europe, the U.K., Brazil and the U.S.

A dense stream of updates hit crypto and AI markets between Aug. 12 and Aug. 13, spanning venture funding, protocol incidents, regulatory moves, exchange actions and large on-chain transfers. PANews’ roundup included Lovable’s $400 million Series C at a $13.3 billion valuation, Wintermute’s plan to spend about $1 billion over five years on high-frequency trading and AI data center infrastructure, and Tencent’s second-quarter results showing higher capital expenditure tied to AI spending. In digital assets, Harmony said it had traced fraudulently minted tokens across 409 wallets and was considering a rollback, while Solana briefly came close to a network-freeze threshold after a data center routing issue knocked nearly 29% of staked SOL offline. Anchorpoint also began the first phase of distributing its Hong Kong dollar stablecoin HKDAP, and Coinbase said it will suspend 10 perpetual contracts on Aug. 26. Whale activity remained active as well, including an Ethereum ICO participant moving 2,000 ETH to Coinbase, a wallet sending 2,300 BTC to Wintermute-linked deposit addresses since June 25, and a leveraged ETH trader closing out positions for a reported $4.3 million profit. The period also brought new product releases from Grok and DeepSeek, a major SEC no-action letter tied to Franklin Templeton’s BENJI fund, and fresh scrutiny of prediction markets from U.S. regulators and New York City lawmakers.

Israeli cybersecurity firm ASecurity said a researcher used publicly available AI models to identify multiple flaws in Zoom’s annotation tool and build an exploitable attack chain in less than 24 hours, using fewer than 20 prompts, according to Decrypt. The vulnerabilities are tracked as CVE-2026-53413, CVE-2026-53414, and CVE-2026-53415. ASecurity said the bugs could let an attacker remotely execute code during a meeting without any action from the victim. In the scenario described by the firm, an attacker could take control of the target device, steal data, or turn on the microphone or camera. The report said the attack was tested successfully across Zoom on Windows, macOS, Linux, Android, and iOS. ASecurity described the exploit chain as reaching a “nation-state” level and said building tools of this kind previously would have required a specialized team, months of work, and a large budget. The firm said it reported the first flaw to Zoom on June 10, and Zoom released patches between June 22 and July 20. A Zoom spokesperson said the issue has been resolved and advised users to stay on the latest version.

Israeli cybersecurity firm A Security has disclosed that researchers used publicly available AI models to uncover vulnerabilities in Zoom's annotation tool and build a working exploit in under 24 hours, using fewer than 20 prompts. The three flaws—tracked as CVE-2026-53413, CVE-2026-53414, and CVE-2026-53415—allow an attacker to join or host a meeting without any victim interaction or visible warning, then target any participant and take over their device. Tests covered Zoom's Windows, macOS, Linux, Android, and iOS apps. Once a device is compromised, an attacker can steal personal data, turn on the microphone or camera, or install additional malware. A Security first reported a vulnerability to Zoom on June 10; Zoom shipped fixes between June 22 and July 20. Because server-side protections can't filter malicious messages in end-to-end encrypted meetings, users are still advised to update to the latest version. Decrypt reported the research.

A Security, an Israeli cybersecurity firm, said a researcher used publicly available AI models to identify flaws in Zoom’s annotation feature and assemble a working exploit in less than 24 hours. In a report published Tuesday and titled "Zoomsday," the firm said the researcher needed fewer than 20 prompts to uncover the issues. According to the report, the exploit could let someone in a Zoom meeting take control of another participant’s device without any action from the victim and without a visible sign that the system had been compromised. A Security said it tested the attack against Zoom apps on Windows, macOS, Linux, Android, and iOS. The vulnerabilities are tracked as CVE-2026-53413, CVE-2026-53414, and CVE-2026-53415. The firm said a compromised presenter could target every participant, while any participant could also target the presenter. Zoom told Decrypt that the issue has already been resolved, though A Security said users still need to update because a server-side safeguard could not block malicious messages in end-to-end encrypted meetings. The report arrives as AI tools are being used more often to find software bugs across the tech industry.
