According to South Korean news reports, the number of crypto-related voice phishing cases skyrocketed in the first half of 2025. Reportedly, there were 420 incidents from January to July, an astonishing 6.6-fold increase compared to just 64 cases in the same period of 2024. Like-for-like, the total for the first seven months already exceeded the 130 cases for the entire 2024 year.

How These Voice Scams Work

These are not mere nuisance calls, they are sophisticated scams where fraudsters impersonate government officials, law enforcement, or financial institutions to pressure victims into transferring their crypto assets. Common tactics include:

  • Urgent security alerts: Victims receive calls claiming their accounts are compromised or involved in illegal activity.
  • Fake investment opportunities: Calling with lucrative, short-lived offers to lure investors into fake platforms.
  • Impersonated support: Self-identified help desk agents request access to wallet details or private keys under the guise of “resolutions.”

These methods prey on panic, trust, and urgency, strong psychological triggers that make it hard to resist, especially under pressure.

How to Protect Yourself: Best Practices

The best defense against voice scams is vigilance and a healthy sense of skepticism. Whenever you receive an unexpected call claiming to be from a government agency, law enforcement, or a financial institution, always verify the caller independently: Hang up (immediately close the phone call) and use official contact information rather than the number provided by the caller. Remember that no legitimate organization will ever ask for your private keys, seed phrases, or direct access to your wallet. Treat any request for such details as an immediate red flag.

Scammers often rely on urgency and fear to pressure victims into acting quickly, so if a caller insists you must resolve a situation “right now,” take a step back and think before responding. Enabling two-factor authentication (2FA) on all your exchange and wallet accounts is another critical layer of protection, making it much harder for fraudsters to gain unauthorized access even if some information is compromised. Finally, staying informed is one of the most powerful tools you have, by regularly educating yourself about the latest scam tactics, you can recognize patterns and avoid becoming another victim of social engineering.
