The anatomy of a phishing attack
Phishing sites targeting darknet markets follow a predictable formula. An attacker registers a .onion address — sometimes differing from the real one by a single character, sometimes completely unrelated but with a matching design. They clone the market's HTML and CSS exactly, replicating the login flow, the CAPTCHA page, and the user dashboard skin.
The attack is self-reinforcing. People search for "DrugHub link" on clearnet search engines, find results pointing to compromised mirror lists or forums with poisoned posts, copy the address, and authenticate against the fake site. A phishing page can capture your PGP-encrypted login response and replay it. It can capture the wallet address you deposit Monero to. One visit to the wrong address is enough.
DrugHub's passwordless PGP login model raises the bar — there's no static password to steal. But the attack surface isn't zero. A phishing site can serve a crafted challenge that, once you respond, lets the attacker authenticate against the real market while you see a "login failed" message. Then they drain your active escrow orders.
The only reliable defense is verifying the address before you open it — not after.
Verifying a DrugHub link step by step
The fastest verification path uses GPG directly against the DrugHub admin's public key. This takes under two minutes.
# Step 1: Import the DrugHub admin public key
# (download from their pinned Dread post)
gpg --import drughub-admin-pubkey.asc
# Step 2: Save the signed mirror announcement as a file
# (copy from the Dread post — includes the -----BEGIN PGP SIGNED MESSAGE----- block)
# Step 3: Verify the signature
gpg --verify drughub-mirrors-2026.txt.sig drughub-mirrors-2026.txt
A valid signature produces output like this:
gpg: Signature made Tue Apr 21 2026 09:47:13 UTC
gpg: using RSA key 4096R/E7B3A1C2
gpg: Good signature from "DrugHub Team [Dread]"
A phishing-sourced address produces:
gpg: BAD signature from "DrugHub Team"
"BAD signature" means stop. Close the terminal, close Tor Browser, do not interact with any address from that source. The Privacy Guides documentation on PGP verification is worth reading for deeper context on this process.
Most people skip this step. That is why phishing attacks keep working. Two minutes of GPG verification eliminates the risk entirely.
Red flags before you log in
Before submitting any input on a DrugHub-looking page, check these:
- The .onion address differs from the verified addresses on this page by even one character.
- The login form has a password field alongside the PGP challenge — real DrugHub is passwordless.
- The site offers Bitcoin as a payment option — real DrugHub is XMR-only, no exceptions.
- You're seeing the page in a standard browser — .onion addresses are only reachable through Tor Browser, never clearnet.
- The PGP verification key fingerprint shown doesn't match 0x7F3A…E91C.
- The CAPTCHA design looks different from what you remember — clones sometimes use their own CAPTCHA implementation.
- A popup or redirect offers "faster access" via a clearnet URL — no legitimate darknet market does this.
- The site loaded in under two seconds — .onion routing through Tor takes time; sub-second loads on first visit are suspicious.
If you've already entered credentials on a fake site
Four steps, in order. Don't wait.
Step 1: Do not send Monero to any wallet address received during that session. The address is controlled by the attacker. The funds are unrecoverable once confirmed on-chain — Monero's privacy features work both ways.
Step 2: Revoke or deprecate the PGP key pair you used in that session. Generate a new 4096-bit keypair with GnuPG. The attacker may have captured enough of your authentication exchange to replay a login on the real market.
Step 3: If you hold an active vendor account, post a warning to your buyers on Dread immediately. Vendor impersonation on dark markets moves fast.
Step 4: Access a verified DrugHub link from this page, log in with your new key, and review your open orders for any unauthorized changes. Cancel any escrow position you didn't initiate.

Tails OS is the gold standard for session isolation — each boot is clean, with no persistent state. Whonix runs Tor at the OS level, ensuring all traffic routes through Tor even if an application misbehaves. KeePassXC manages PGP passphrase storage without cloud exposure. VeraCrypt handles encrypted container storage for key files. None of these guarantee safety, but layering them makes casual phishing attacks irrelevant against your session.
