In a statement released Wednesday, the Secret Service announced its collaboration with the British Columbia Securities Commission (BCSC), Canadian law enforcement, blockchain analytics firms, and several crypto trading platforms.

Approval phishing is a form of crypto scam in which fraudsters trick users into approving malicious transactions, granting attackers the ability to drain assets from their wallets. These scams often use deceptive links, fake websites, or social engineering to lure victims into authorizing wallet access.

The wallets targeted in Operation Avalanche were found to have lost millions in digital assets due to such schemes.
