    1. We experienced a sudden and extreme spike in Gemini API usage. The traffic was not correlated with our actual users and appeared to be automated.

      描述了高达54,000欧元的账单激增现象,表明AI API使用监控和防护存在严重漏洞,这种自动化滥用突显了当前API安全机制的脆弱性,对AI服务提供商和开发者都是警钟。

    1. select known-vulnerable dependency versions 50% more often than humans.

      这一统计洞察颠覆了“AI写代码更安全”的迷思。AI代理在优化代码功能性时,往往以牺牲安全性为代价,倾向于选择存在已知漏洞的旧版本依赖。这反映出当前AI模型在训练时对安全维度的忽视,也警示我们在AI辅助开发流程中必须强制引入自动化的安全卡点。

    1. That means if an attacker can inject some JavaScript code that runs on the web app’s domain, they can steal all the data in localStorage. The same is true for any third-party JavaScript libraries used by the web app. Indeed, any sensitive data stored in localStorage can be compromised by JavaScript. In particular, if an attacker is able to snag an API token, then they can access the API masquerading as an authenticated user.

    1. Could you please explain why it is a vulnerability for an attacker to know the user names on a system? Currently External Identity Providers are wildly popular, meaning that user names are personal emails.My amazon account is my email address, my Azure account is my email address and both sites manage highly valuable information that could take a whole company out of business... and yet, they show no concern on hiding user names...

      Good question: Why do the big players like Azure not seem to worry? Microsoft, Amazon, Google, etc. too probably. In fact, any email provider. So once someone knows your email address, you are (more) vulnerable to someone trying to hack your account. Makes me wonder if the severity of this problem is overrated.

      Irony: He (using his full real name) posts:

      1. Information about which account ("my Azure account is my email address"), and
      2. How high-value of a target he would be ("both sites manage highly valuable information that could take a whole company out of business...")

      thus making himself more of a target. (I hope he does not get targetted though.)

    2. That is certainly a good use-case. One thing you can do is to require something other than a user-chosen string as a username, something like an email address, which should be unique. Another thing you could do, and I admit this is not user-friendly at all, to let them sign up with that user name, but send the user an email letting them know that the username is already used. It still indicates a valid username, but adds a lot of overhead to the process of enumeration.

    1. "We demonstrate that well-known compression-based attacks such as CRIME or BREACH (but also lesser-known ones) can be executed by merely running JavaScript code in the victim’s browser. This is possible because HEIST allows us to determine the length of a response, without having to observe traffic at the network level."

      HEIST attacks can be blocked by disabling 3rd-party cookies.

    1. Businesses need to be more careful to avoid revealing customers' personal information. And they should record calls, and watch them collectively over time for signs of suspicious activity.

      The harasser in this article tricked customer service representatives into giving him private details about his victims. Starting with whatever information he could find online (a birthdate, the name of a pet) he would call repeatedly until he succeeded in getting other details -- which would make him still more convincing, so he could get more details.

      In one case, he pretended to be a company technician for ISP Cox Communications. They didn't have a procedure to verify the ID of their own technicians?

    1. All new Dell laptops and desktops shipped since August 2015 contain a serious security vulnerability that exposes users to online eavesdropping and malware attacks.

      "At issue is a root certificate installed on newer Dell computers that also includes the private cryptographic key for that certificate. Clever attackers can use this key from Dell to sign phony browser security certificates for any HTTPS-protected site."
