Bithumb launched an anti‑phishing campaign after seeing a surge in AI‑powered voice‑phishing and deepfake video scams targeting crypto investors in South Korea.

The exchange released a guide called the “Voice Phishing Complete Guide,” warning users that criminals are now using artificial intelligence to impersonate trusted people during phone calls and video meetings.

According to the campaign, scammers may:

• Clone the voice of a family member, colleague, or exchange employee
• Use AI‑generated video calls that appear to show legitimate support staff
• Pressure victims into revealing login credentials or approving transactions

Because crypto transactions are irreversible, these tactics can lead to immediate losses once funds are transferred or wallet permissions are granted.

Ripple CTO David Schwartz: Deepfakes and Fake Airdrops Are Escalating

Ripple CTO (and XRP Ledger architect) David Schwartz issued his own alert to the XRP community in May 2026, warning that scams targeting XRPL users have “hugely escalated.”

Schwartz said attackers are increasingly using:

• Fake XRP giveaways or airdrops
• Impersonation accounts posing as Ripple staff
• Fraudulent websites that request wallet connections
• Wallet‑drainer transactions triggered by malicious smart contracts

Ripple has repeatedly emphasized that the company does not ask users to send XRP in order to receive more in return, a classic tactic used in crypto giveaway scams.

In some cases, scammers have also circulated AI‑generated videos impersonating Ripple executives to promote fraudulent reward programs or token distributions.

How AI Is Changing Crypto Scam Tactics

Security researchers and exchanges say the biggest shift is how realistic scams have become. Instead of simple phishing emails, criminals now use generative AI to automate social engineering.

Common tactics include:

• Deepfake videos: Fake clips of well‑known crypto leaders or influencers promoting “official” investment opportunities.
• AI voice cloning: Calls impersonating exchange staff, government officials, or even relatives asking for urgent transfers.
• Fake airdrops and giveaways: Websites that ask users to connect wallets or send crypto to “verify” eligibility.
• Wallet‑drainer sites: Malicious dApps that request token approvals and silently drain funds.
• Impersonation accounts: Social profiles that mimic exchanges, project teams, or executives.

Because these attacks combine technical tricks with psychological pressure, even experienced users can be fooled.

The Data Shows Crypto Fraud Is Growing

Official statistics reinforce the warnings from industry leaders.

• The FBI’s Internet Crime Complaint Center reported $16.6 billion in total internet‑crime losses in 2024, the highest on record at the time.
• In 2025, Americans reported more than $11.3 billion in cryptocurrency‑related fraud losses, making crypto the largest category of financial losses in cybercrime complaints.
• Some industry reports suggest AI‑enabled crypto scams have grown rapidly, with activity rising sharply as generative AI tools become easier for criminals to use.

While estimates vary depending on methodology, the overall trend is clear: digital‑asset investors remain a prime target for increasingly sophisticated scams.

How Crypto Investors Can Protect Themselves

Security experts and exchanges recommend a few consistent practices to reduce risk:

• Never share seed phrases or private keys. Legitimate companies will never ask for them.
• Assume giveaways that require sending crypto first are scams.
• Verify airdrops and promotions through official websites and channels only.
• Avoid wallet connections from links in DMs, ads, livestream chats, or unsolicited messages.
• Use two‑factor authentication with an authenticator app or hardware key.
• Double‑check transaction details before signing, including addresses and token approvals.
• Use a separate wallet for experiments or airdrops, while keeping long‑term funds in cold storage.

If something feels urgent, unusual, or too good to be true, pause and verify through a trusted channel.

The Bottom Line

The warnings from Bithumb and Ripple’s David Schwartz reflect a larger shift in cybercrime: AI is making scams faster, cheaper, and more convincing.

Deepfake videos, cloned voices, and automated phishing campaigns allow attackers to impersonate trusted figures and organizations at scale. As adoption of digital assets grows, security awareness and careful wallet practices are becoming just as important as investment strategy.
