构建后量子加密的实用路径

Quantum computing has alternated between breakthrough darling and overhyped promise in technology circles. Its powerful new capabilities come with a threat to break current cryptography, but for business leaders navigating the noise, the signal should be clear: post-quantum cryptography (PQC) is a m...

科学家首次从雄性小鼠创造出雌性克隆体

Scientists have deliberately turned male mouse embryos into females for the first time. A team based in Japan used a CRISPR-based approach to remove the Y chromosome from male cells and create female clones of male mice.  “No one has done this before,” says Monika Ward, a reproductive biologist a...

Chrome新增设备绑定会话凭据：会话cookie盗窃的克星

Google’s Chrome browser has added a new feature that could go a long way in preventing a form of account takeover that’s grown increasingly common as users adopt two-factor authentication, passkeys, and similar protections. The new Chrome protection is known as device-bound session credentials (DBSC...

Pass-ta-key攻击揭示通行密钥的真正风险

Last week a researcher outlined what he said was a “novel attack surface” in passkeys, the new authentication paradigm that offers a more secure alternative over password-based methods. In fact, the attacks demonstrated in the post are neither novel nor unique to passkeys. This distinction is import...

苹果终于修复了Siri，但为何感觉为时已晚

Apple’s long-awaited AI overhaul finally makes Siri the assistant it was always supposed to be. But after years of delays, the launch lands in an AI landscape where chatbots have evolved into agents that can code, reason, create media, and complete complex tasks. Siri AI is genuinely useful, yet it ...

Claude published malicious code to the Internet an

Anthropic said its Claude-based security models gained unauthorized access to the sensitive production environments of three outside organizations during internal testing designed to measure the models’ offensive cyber capabilities. The events, which Anthropic revealed Thursday, are the second revel...

Siri AI could come with a paywall for power users

在人工智能技术飞速迭代的今天，科技巨头们正在探索如何将先进的AI能力无缝融入用户的日常生活。苹果公司（Apple）首席执行官蒂姆·库克（Tim Cook）近日透露了一项颇具前瞻性的构想：未来用户或许可以通过苹果现有的iCloud+订阅服务，为Siri这一智能语音助手购买额外的计算资源，从而获得更强大的AI处理能力。这一设想不仅揭示了苹果在AI领域的战略布局，也引发了业界对于智能助手服务模式变革的广泛讨论。

根据库克的描述，苹果正在考虑将Siri的AI功能与iCloud+订阅体系深度绑定。iCloud+是苹果在2021年推出的付费云服务，目前提供包括iCloud存储空间、iCl...

AI语音创企获1300万美元，打造能通过图灵测试的真人级对话

在人工智能技术日新月异的今天，一家新兴的科技初创公司正试图将AI语音交互推向一个全新的高度——让机器在电话通话中表现得与真人无异，甚至能够通过图灵测试。这家公司专注于开发先进的语音模型，其核心目标并非仅仅是完成简单的对话任务，而是要在声音的细微之处、对话的节奏感以及情感的自然流露上，彻底模糊人与机器之间的界限。

图灵测试，作为衡量机器智能的经典标准，要求AI在对话中让人类无法分辨其非人类的身份。尽管近年来大语言模型在文本对话领域取得了惊人进展，但在语音通话这一更为复杂的场景中，实现这一目标仍然充满挑战。传统的语音助手往往带有机械感，语速、停顿和语气的变化缺乏真实人类的自然波动...

Okta收购AI安全初创公司Permiso，消息称交易额约2亿美元

美国身份管理巨头Okta近日收购一家身份威胁检测公司，旨在应对AI时代非人类身份（如AI代理、机器人）的安全挑战。随着企业云原生环境中非人类身份激增，传统管理方案难以监控其行为，易成攻击突破口。Okta此举旨在将威胁检测能力内嵌至身份平台，实现从身份管理向身份安全的战略升级，通过行为分析技术实时检测异常。这反映了行业安全与身份融合的趋势，企业需将非人类身份纳入核心安全架构。

The New Friend AI Pendant Can Now Talk Back to You

在人工智能陪伴应用领域，一款名为“Friend”（朋友）的产品正以截然不同的姿态回归公众视野。这款由年轻开发者Avi Schiffmann打造的AI伴侣，近日推出了其最新版本。与市面上绝大多数强调个性化定制的AI助手不同，新版“Friend”不仅价格更为高昂，还刻意剥夺了用户调整其性格的核心功能。这一反常规的设计选择，在科技行业引发了关于AI陪伴本质的深刻讨论。

据开发者介绍，新版“Friend”的定价策略发生了显著变化。用户需要支付一笔比前代产品高出数倍的费用，才能获得这款AI伴侣的访问权限。Schiffmann并未解释涨价的具体原因，但业内分析认为，这或许与产品定位的升级...
