Anthropic has launched an authentication mechanism in some use cases of Claude to prevent abuse, enforce usage policies, and fulfill legal obligations. This process is supported by Persona, requiring users to submit a government-issued photo ID and possibly undergo real-time selfie verification.Anthropic states that the verification data is only used to confirm identity, not for model training, and will not be used for marketing or advertising. If verification fails, users can retry multiple times within the process or submit a form to request manual assistance. Accounts may be banned in cases of repeated violations of usage policies, terms of service, registration from unsupported regions, or use by individuals under 18 years of age.

Claude announced the launch of Managed Agents, a feature that helps developers quickly build and deploy large-scale AI agents on the Claude platform, now entering the public testing phase. By combining performance-optimized AI agent runtimes with infrastructure suitable for production environments, AI agents can go from prototype to launch in just a few days, increasing the speed of building and deploying agents by 10 times.It provides managed infrastructure that automatically handles complex tasks such as sandboxing, error recovery, memory, and checkpoints, allowing users to simply define tasks, tools, and guardrails.

Claude Code Product Manager Noah Zweben posted, "/autofix-pr can now be launched directly from the command line for automatic fixes. After completing a PR, just run this command. It will upload your session to the cloud, allowing the PR auto-fix tool to have the complete context to handle CI failures and comments."

AI company Anthropic announced that starting from April 4 at 15:00 Eastern Time, it will prohibit access to third-party tools through the Claude subscription service, including the open-source project OpenClaw. The new regulations require that related features can only be used through additional packages or billed on a pay-as-you-go basis via API.This adjustment means that many developers and teams relying on OpenClaw to build automated workflows will shift from a fixed subscription cost model to an unlimited pay-as-you-go system, significantly increasing overall usage costs. Some developers have indicated that the original usage cost of about $20/month could soar to hundreds or even thousands of dollars.The market generally believes that this move is related to OpenClaw founder Peter Steinberger's recent joining of OpenAI. Meanwhile, Anthropic is accelerating the promotion of its own tool ecosystem, including native integration solutions for Claude, to replace third-party toolchains.It is worth noting that Anthropic has previously tightened third-party access through technical restrictions, updates to service terms, and feature replacements. This policy is seen as a "final blockade" and will be extended to more tools.Industry analysis points out that this event reflects an intensifying trend of "ecosystem tightening" in AI platforms, with leading companies strengthening control through vertical integration. At the same time, the developer ecosystem faces rising cost uncertainties and platform dependency risks, which may further drive some users toward more open alternatives.

Microsoft announced on Monday the launch of two new features for Copilot Researcher—Critique and Council—combining OpenAI's GPT with Anthropic's Claude for the same research task.Critique adopts a sequential collaboration model: GPT is responsible for planning the research, retrieving information, and generating the first draft, while Claude serves as a strict reviewer, checking the accuracy of facts and the quality of citations; Council allows both models to independently generate reports in parallel, with a third referee model comparing differences and summarizing discrepancies.In the DRACO benchmark test covering 100 complex research tasks across 10 fields including healthcare, law, and technology, Copilot equipped with Critique scored 57.4 points, leading the second place by nearly 14%, far surpassing Claude Opus running alone with a score of 42.7 points.

According to a report by Fortune magazine, documents leaked from Anthropic show that its next-generation super robot "Claude Mythos" is currently being tested, and the company believes that this robot "poses an unprecedented cybersecurity risk." Musk stated, "This is deeply concerning."

According to GoPlus citing a Koi report, the Claude Chrome extension under Anthropic has a high-risk prompt injection vulnerability, affecting all versions of the extension below 1.41.Attackers can construct malicious web pages that silently load an iframe containing a cross-site scripting (XSS) vulnerability in the background, executing malicious payloads within the a-cdn.claude.ai subdomain. Since this subdomain is on the extension's trust whitelist, attackers can directly send malicious prompts to the Claude extension and execute them automatically, without requiring user authorization or any clicks, leaving the victim unaware.This vulnerability can allow attackers to manipulate the Claude extension to read users' Google Drive documents, steal business access tokens, or export chat logs, and can take over the current browser session to perform sensitive operations like sending emails as the victim. GoPlus recommends that users immediately update the Claude extension to version 1.41 or above and remain vigilant against phishing links.

Claude announced the launch of the new feature Claude Code Code Review. When a Pull Request (PR) is created, Claude sends a group of AI agents to simultaneously search for potential code vulnerabilities.The agents search for vulnerabilities in parallel, validate each vulnerability to reduce false positives, and prioritize the vulnerabilities by severity. Ultimately, users receive a summary comment along with inline annotations in the code.

According to Bloomberg Terminal, a hacker used Claude to infiltrate the Mexican government system, stealing 150 GB of sensitive data, including taxpayer and voter records.Researchers at Gambit Security stated that the attackers utilized artificial intelligence to find vulnerabilities, write attack scripts, and automate the theft process, ultimately bypassing security measures through repeated "jailbreaking" attempts. This security breach affected multiple agencies in Mexico, and artificial intelligence is accelerating cybercrime.

Anthropic announced the release of a new charter for its AI model Claude, which details Anthropic's vision for Claude's values and behaviors.In the new charter, Anthropic upgrades Claude's soul document from a rulebook to a textbook that combines values and reasoning, hoping that Claude can become wiser, safer, and capable of making moral judgments on its own, rather than strictly adhering to rules. This is currently the most detailed publicly available AI personality setting and ethical constitution document.

The Slow Fog team security researcher 23pds forwarded a report from researcher Adam Chester, revealing a privilege escalation and command execution vulnerability found in Anthropic's Claude Code. Attackers can execute commands without user authorization. The vulnerability ID is CVE-2025-64755, and a related PoC has been made public.This issue has been noted to be similar to a previously disclosed vulnerability in the Cursor tool. 23pds stated that phishing hackers have already exploited the related vulnerability to attack cryptocurrency users.
