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...
上周,一位研究人员 outlined 了他所说的通行密钥中的"新型攻击面"——通行密钥是一种新的认证范式,提供了比基于密码的方法更安全的替代方案。事实上,帖子中 demonstrated 的攻击既不新颖也非通行密钥独有。这种区别很重要,因为该研究在最终用户和安全专业人士评估这种新机制是否 truly 安全使用时引起了 confusion。
该攻击称为Pass-ta-key——是通行密钥与"传递密钥"短语的混合,也是对一盘 pasta 的致敬。安全公司Palo Alto Networks的研究员阿里·奥尔施泰因上周在一篇文章中 described 了Pass-ta-key如何在感染了恶意软件的机器上运行时,获取存储在Google密码管理器应用(GPM)中的所有通行密钥。
这让许多人感到 surprise,因为他们 believed 通行密钥 exclusively 存储在可信平台管理器(TPM)中——TPM是 hardened silicon chip 中的 locked-down enclave, reserved for 在Windows机器上存储加密密钥和其他高度敏感信息。如果通行密钥存储在TPM中,那么Pass-ta-key如何能够提取应用存储的整个通行密钥集,他们想知道?
The AI boom is becoming a materials challenge. As AI pushes computing into new territory, the materials behind that infrastructure are becoming just as crucial as the algorithms running on it. Semiconductors and data centers are approaching physical limits around performance, thermal management, ele...
Cloudflare said Tuesday it plans to issue quantum-proof TLS certificates, making it one of the first authorities to issue such certificates that use a form of cryptography that is widely believed to withstand attacks from quantum computers.
The Internet infrastructure provider said it will use an op...
Vaccines that turn the body’s immune system against tumors have shown promise in clinical trials, and a handful have been FDA approved for certain cancers. In many patients, however, these vaccines don’t stimulate enough of a response, and the approach some researchers have taken to strengthening it...
When customers talk about AI costs, the conversation usually starts with token prices and ends with access to the latest, most capable model in the cloud. Do they always need that level of capability? Not necessarily. But that is often where the conversation goes.
As AI moves from experimenta...
