Fake Claude Max giveaway hides a Google account phishing trap
Phishing follows whatever people want at the moment, and right now that includes AI subscriptions they don’t have to pay for. We recently uncovered a new variation on this theme: A fake Claude Max giveaway that uses a convincing Google sign-in window to steal login information.Claude’s paid plans start at $20 a month and cost considerably more for higher usage limits, while free accounts have stricter limits. That makes the promise of a free upgrade an attractive lure.Microsoft reported in June…

Macfinger ClickFix campaign, (Tue, Sep 22nd)
Introduction I've found several legitimate websites with injected script for a campaign using the ClickFix social engineering technique. This particular ClickFix campaign was documented earlier this month on the Ransom-ISAC Blog, but it doesn't appear to have a nickname yet. Since this campaign is targeting macOS environments through a fingerprinting process, I'm calling it the "Macfinger ClickFix" campaign. No, this is not related to the MacFinger utility from decades ago. Instead, think of…

Apart from the privacy concerns around smart glasses, researchers have found that some cheap brands come with barely any security at all. ABC Australia reports that researchers from NSB Cyber and Abstract Shield tested two inexpensive pairs, costing A$60 and A$110 (around US$42 and US$78), and found more than a dozen flaws across the smart glasses themselves, their app, and an associated website.

The Truth about GET and HTTP Standards, (Tue, Sep 22nd)
On Friday, Xavier talked about the newly introduced HTTP Query method. This new method was introduced to allow "GET" requests that include a body. The main reason for this was that GET requests typically do not contain a body. But what if they do? I did a quick check of a couple of common web servers I had handy, to see what would happen: Apache For this test, I ran Apache 2.4.68 on a Mac. It happily accepted a body with a GET request: % nc -c localhost 8080 GET /cgi-bin/test-cgi HTTP/1.1 Host:…

Meta’s Muse AI assistant has a zero-day that can turn it into a Mac backdoor
Mac security researcher Patrick Wardle says it’s trivial to turn Muse into “the ultimate backdoor.” Increasingly, AI assistants are changing from tools that simply answer questions into agents that can plan tasks, use connected services, and take actions for us. These actions might include booking appointments, filling out forms, creating documents, making purchases, or interacting with email and calendars. To do that, they need more permissions, account connections, and sensitive data. So,…

While we do not have confirmation of in-the-wild deployment, artifacts from the binary were used to connect the developer to postings on criminal forums related to carding, dating back to 2025. This malware is a useful reference example of how attackers can collapse the decision space of a particular attack phase into a constrained set of choices, allowing AI models…

Introducing CAIRN: Frontier tracking for AI-integrated malware
A cairn is a marker left behind on a trail, a deliberately placed stack of stones that helps hikers find their way when the path is unclear. Attackers building AI-integrated malware unintentionally (and inevitably) leave behind markers of their own: prompt templates, provider endpoints, API keys, jailbreak terms, and other artifacts embedded throughout their tooling. When we consider these strings as cognitive artifacts, or vestiges left behind from AI integration, we can enable a new, metadata…

In June 2026 the IETF published RFC 10008[1], defining a new HTTP method: "QUERY". The HTTP protocol faced already by changes (HTTP/2, HTTP/2) but it’s the first new standard HTTP verb since "PATCH" in 2010! This new method sits between “GET” and “POST” and can be resumed like this: “QUERY is a GET with a body”. It's safe and idempotent: the request is processed without state change and can be automatically repeated or restarted without concern for partial state changes. The query itself lives…
