They say money doesn’t talk—but with today’s scammers, it certainly sounds like it does. And if that voice sounds suspiciously like your CTO or a government official, you might be on the wrong end of a “vishing” call.
Cybercriminals are now running professional voice-impersonation schemes targeting U.S. crypto executives. According to new research by GK8 (a Galaxy company), fraud groups are recruiting skilled impersonators—some earning up to $20,000 a month—to con high-level leaders into handing over access to sensitive systems and private keys.
Here’s how it works:
Step one—hackers gather detailed personal and professional information on crypto executives from compromised databases.
Step two—they hire professional “callers” who can mimic voices, accents, and even mannerisms using AI-enhanced tools.
Step three—these callers place highly convincing phone or video calls, posing as banks, regulators, or even colleagues, pressuring executives to share credentials or approve transactions.
Who’s targeted?
High-value crypto professionals like CTOs, engineers, legal officers, and controllers—essentially, anyone with access to custody infrastructure or multi-million-dollar wallets.
Real-life example:
In June, researchers spotted recruitment ads on underground forums seeking English-speaking impersonators to call a shortlist of five U.S. crypto executives worth at least $500,000 each. Compensation ranged from $15 for a quick 20-minute call to $20,000 per month for experienced operators. As Tanya Bekker, GK8’s Head of Research, put it: “It is a business, and threat actors take their job very seriously.”
Why should you care?
Because these scams aren’t about everyday bank fraud—they’re aiming for large-scale crypto theft. A single compromised call could mean millions of dollars drained from wallets or irreversible loss of digital assets. Beyond money, reputational damage, regulatory fallout, and personal liability for executives are all very real risks.
Here’s how to protect yourself (or your organization):
- Assume your data is exposed—don’t rely on secrecy; rely on layered defenses.
- Never approve high-value transactions alone—require multi-person sign-off for private keys and transfers.
- Verify requests on a separate channel—if you get a call about an urgent transfer, confirm by secure messaging or in person.
- Train your team regularly—make sure staff can spot deepfake voices, suspicious calls, and pressure tactics.
- Limit information exposure—reduce how much personal and corporate data is publicly available online.
Quick Tips
- Did you know? Vishing gangs now select callers based on accent, gender, and time-zone availability to maximize success. It’s that personalized.
- Pro Tip: Slow the conversation down. Scammers rely on urgency. If you feel rushed, hang up and call back on an official line.
Stay safe, stay informed.
