The Ultimate Security Anti-Pattern: A Website for 'Checking' Private Keys
Description
A screenshot of a website with the URL 'isanybodyusingthisprivatekey.com'. The site's header boldly asks, 'Is anybody using this private key?'. Below, instructive text reads, 'Your private key is not safe anymore if someone else has already taken it. Paste your private key below to check if it is already taken.' A large text area displays a full RSA private key, including the '-----BEGIN PRIVATE KEY-----' and '-----END PRIVATE KEY-----' markers. Beneath this, a dropdown menu is set to 'SSH Login'. The most humorous part is the result section, which shows a green checkmark and the word 'Success!' next to a Cloudflare logo, all above a blue 'Check' button. This image is a piece of expert-level satire aimed at anyone familiar with cybersecurity fundamentals. The entire premise is a parody of a phishing attack or honeypot, as the absolute first rule of cryptography is to never, ever share your private key. The joke is in the audacity of the request, and the ironic 'Success!' message creates a brilliant piece of dark humor, implying that the 'success' is the theft of the key. It's a perfect in-joke for senior developers and security professionals who would instantly recognize the catastrophic security flaw being presented as a 'service'

I'm not saying I pasted my key, but my entire home directory just pushed itself to a public GitHub repo titled 'free-server-access-keys-for-educational-purposes'
Finally, a SaaS that turns RCE into Remote Credential Extraction - just paste your key and *boom*, problem transferred to someone else’s server
This is the cybersecurity equivalent of a 'Free Candy' van asking kids to hop in and check if their candy is poisoned - except the van has a Cloudflare sticker, so at least your private key will be compromised with enterprise-grade DDoS protection
This is the cryptographic equivalent of 'haveibeenpwned.com' but for people who fundamentally misunderstand asymmetric encryption. It's like asking 'Is anyone else using my house key?' by mailing your only copy to a stranger. The real genius is that anyone who actually uses this service has already failed the security awareness test so catastrophically that the 'Success!' message is technically accurate - they've successfully compromised their own infrastructure. At least when junior devs commit AWS keys to GitHub, it's usually an accident; this requires deliberate, step-by-step incompetence
If your PEM ever touches a web form, the answer is already yes - execute the incident runbook, rotate every authorized_keys, and accept that “Check” was the attacker
Finally, a self‑serve exfiltration endpoint: paste your SSH private key, clear Cloudflare’s Turnstile, and get a green “Success!” - for the attacker’s secrets-management pipeline
When your infra key's 'private' status is verified by a public pastebin - rotate yesterday, or it's already prod-owned

The deep state blocked the website claiming it's "for fraudulent purposes". So much for freedom of speech Comment deleted
