Bitget Wallet said it will expand AI-assisted threat detection, according to a ChainCatcher report published on November 11, 2026.
In the third quarter of 2026, the weekly average number of signature requests flagged as potential phishing rose 7.4-fold, from about 5,000 in the second quarter to about 37,000. Alvin Kan, chief operating officer of Bitget Wallet, said the increase may reflect both more threat activity and improved detection, but the available data cannot quantify how much each contributed. He said the figures count flagged signature interactions, not separate attack events or confirmed losses of funds.
The report says Bitget Wallet introduced AI-assisted risk detection in the second quarter. The expanded AI checks analyze website code and domain-registration information for signs of fraud, and simulate a transaction before a user signs in order to find hidden permissions. Of high-risk domains newly blocked in October, 90% were identified by AI, compared with 36% in the second quarter. Nearly 70% of the domains AI flagged that month had no matching alert in the external threat-intelligence sources the company checked.
ChainCatcher also described earlier phishing aimed at crypto users. In July 2026, a trader lost nearly $1 million after signing a malicious Ethereum token approval. In August 2026, a Rapid7 investigation found a phishing campaign that targeted 885,000 phone numbers and directed recipients to sites impersonating crypto wallet providers.
The report leaves unresolved how much of the third-quarter rise came from additional phishing activity and how much from the detection changes. The published totals are not a measure of confirmed attacks or of money lost.
