What happened
On June 20, 2025, Japanese cryptocurrency influencer Mai Fujimoto fell victim to a deepfake video scam after being tricked into a Zoom call with a video impersonation of an acquaintance whose Telegram account had been compromised.
During the call, the deepfake appeared convincing for about 10 minutes, but the attacker claimed audio issues and sent a link supposedly to fix the problem. After Fujimoto clicked the link, malware was installed that compromised her Telegram, MetaMask, and X accounts.
Reported impact
Fujimoto's main X account was hijacked, forcing her to warn followers not to click links from the account. Her Telegram and MetaMask accounts were also compromised.
Index analysis
Binance founder Changpeng Zhao warned that AI-powered deepfakes represent a growing threat to security, noting that even video call verification will soon become unreliable. A Bitget report indicated deepfake technology was involved in nearly 40% of high-value crypto frauds in 2024.
Governance controls
Zhao urged users not to install software from unofficial links, even if they appear to come from trusted contacts.
