Crypto Conferences Are Booming — So Are Scams, Experts Warn

Crypto events are growing fast — from Dubai’s skyline to Singapore’s smart halls — but cybersecurity experts are sounding the alarm. According to Nick Percoco, Chief Security Officer at Kraken, scammers are infiltrating these conferences with increasingly sophisticated and low-effort tactics.

“Crypto conferences have scaled massively, but personal security hasn’t kept up,” says Percoco. “And that’s a problem.”

Why Crypto Events Are Now Prime Targets

These conferences have become hotspots for networking — and for cybercriminals. From QR code phishing to fake Wi-Fi networks, scammers exploit the informal atmosphere to target unguarded wallets and devices.

Kraken staff have reported seeing unattended laptops with open wallets, phones buzzing with sensitive notifications, and even investors discussing trades in public places.

“If you’re in crypto, your laptop isn’t just a device — it’s a vault,” Percoco warns.

The Most Common Scams Happening at Crypto Events

• Fake QR codes (sticker swaps)
• Phishing links sent as calendar invites
• Hijacked public Wi-Fi
• Impersonation through lanyards and event badges

Attackers can easily blend in by pretending to be fellow attendees or company reps. Once inside, it takes just one click to compromise your device.

When Crypto Scams Turn Violent: The France Kidnapping Case

In one of the most terrifying incidents yet, David Balland, co-founder of Ledger, was kidnapped, mutilated, and held for ransom in France. This high-profile attack highlighted how real-world violence is becoming part of the crypto threat landscape.

Other physical attacks in Europe have also emerged, often targeting known holders or founders, sometimes even extending to their families.

Avoid These Common Security Mistakes

Percoco’s biggest concern isn’t advanced hacking — it’s carelessness. Too many attendees forget basic security practices in the excitement of networking.

Simple tips:

• Use burner wallets with limited funds
• Never leave laptops or phones unlocked
• Don’t scan unknown QR codes
• Use hardware MFA like YubiKey
• Beware of public charging stations (“juice jacking”)

Your Personal Info Is a Goldmine

According to a16z crypto security engineer Matt Gleason, even a small data breach — like leaking a phone number — can escalate into full-blown identity theft. From SIM swaps to phishing attacks, one slip-up can cost you everything.

He recommends freezing your credit, securing sensitive apps behind Face ID, and using password managers to create strong, unique logins for every account.

Conferences Must Take Responsibility Too

Percoco points out that event organizers collect names, emails, and phone numbers — which could be weaponized if leaked. He urges more stringent data practices, improved on-site security, and better attendee awareness campaigns.
