docs--app-trezr.gitbook.io is an impersonation phishing page hosted on GitBook. The misspelled name "app-trezr" and the "docs" prefix make it look like official Trezor help or setup documentation. It targets Trezor hardware wallet owners who search for setup guides, firmware help or the Trezor app. PhishDestroy first flagged it on 2026-09-15. When checked on 2026-10-19 it was still online and redirecting visitors elsewhere.
How the scam works
Fake documentation pages like this trade on the trust people give a familiar knowledge-base layout and a legitimate publishing platform. A visitor who expects official instructions is pushed toward a "connect", "verify" or "restore" step. That step usually leads to a form asking for the wallet's recovery seed or to a download posing as wallet software. The page currently redirects, so the first click sends visitors to a destination the operator controls. Anyone who types a recovery phrase into such a flow hands over full control of the wallet, and the funds can be swept without the physical device.
Evidence
On 2026-09-23, 11 of 89 VirusTotal engines flagged the address. The vendors included alphaMountain.ai, BitDefender, CyRadar, Emsisoft, G-Data, Kaspersky, Lionic and Netcraft. These are independent engines reaching the same verdict. Spamhaus lists it in its DBL as DBL_ABUSED_PHISH, a category for phishing hosted on an otherwise legitimate domain, which matches a malicious GitBook space. PhishDestroy also carries it on its own blocklist.
Infrastructure
The 2014-03-30 registration date and the Cloudflare, Inc. registrar belong to the parent gitbook.io platform, not to this operator. The scammer only had to create a free subdomain. Traffic resolves through Cloudflare's network, geolocated to Canada. The TLS certificate from Google Trust Services is the platform's own, so the padlock says nothing about who runs the page. This low-cost setup lets the operator borrow a reputable domain's standing while spending almost nothing.
What to do
Never type a Trezor recovery seed into any website, form or app prompt. Genuine Trezor devices only ask for it on the device itself during recovery. If you entered your seed here, set up a new wallet with a fresh seed on your device and move all funds immediately, because the old seed must be treated as compromised. If you downloaded anything from the redirect, uninstall it and scan the machine before using it for crypto again. Defenders should block the subdomain and its redirect targets, and report the space to GitBook for removal.

After a phishing incident
Recommendations & Advice for Victims
Choose the steps that match what you shared. Keep a copy of this report alongside your own records.
What should I do immediately?
Urgent
Stop using the suspicious site. Open the real service through its official app or an address you already trust.
Change all passwords — email, exchange accounts, anything that shares the same password
Enable 2FA using an authenticator app (not SMS). Disable SMS-based recovery
Freeze cards if you entered banking details on the phishing site
What information should I collect for my report?
FBI guidelines
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Exact dates & times — of each transaction and first contact with scammer
Screenshots — scam website, chat messages, emails, wallet transactions, social media
All URLs & domains used by the scammer (including docs--app-trezr.gitbook.io)
Communications — emails, texts, phone numbers, usernames the scammer used
Even if you don't have all details — file a report anyway. Partial information still helps investigations.
Where should I report the scam?
FBI IC3 — Internet Crime Complaint Center (US federal reporting)
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
Local police — creates an official record, even if they can't act immediately
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
Recovery scams — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect
How can I protect myself in the future?
Bookmark official sites — never click links from emails, DMs, or ads
Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
"Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines
