Fake Collab Invites

“You’ve been selected for a collab.”
“Let’s build together.”

They’re not building.
They’re baiting.

Always verify partnerships from official channels.

Malicious Browser Pop-ups

A random pop-up says:
“Your wallet is disconnected — reconnect now.”

You click.
You’re compromised.

Never connect through pop-ups.
Always open your wallet manually.

Phishing PDFs

Email arrives.
“Claim NFT drop — details inside.”

The PDF looks normal.
The link inside? Malicious.

Never trust links hidden in files.

Malicious Wi-Fi

Free airport Wi-Fi.
Café hotspot.
NFT conference Wi-Fi.

Scammers run fake networks.
You connect.
They snoop.

Avoid public Wi-Fi for wallets.

Compromised QR Codes

Posters.
Flyers.
Conference booths.

“Scan to mint.”
Looks harmless.
One scan = wallet drainer.

Never scan random QR codes.

Bookmark Malware

Scam sites ask:
“Bookmark us for quick access.”

Later… that bookmark runs code.
Not a shortcut — a trap.

Only bookmark legit domains.
