Bitget Wallet expands AI screening as phishing detections surge

The company said AI identified 90.2% of newly blocked risky domains in the first four weeks of Q4, up from 70.2% in Q3 and 36.3% in Q2. In early Q4, 69.8% of those domains had no matching risk alerts in two external threat-intelligence databases used for comparison; the share was 56.3% in Q3. Bitget Wallet rounded the October figures to 90% and nearly 70% in its announcement.

In Q3, phishing-related signing requests made up 57% of detections across four monitored categories. Malicious addresses accounted for 17%, risky contracts for 14% and malicious approvals for 12%. These figures describe detections within the company’s systems; the 7.4-fold rise refers to weekly averages between the quarters.

The expanded checks are part of GetShield, Bitget Wallet’s security engine. The company said it examines website code for fraud or impersonation and checks domain registration details and links to known malicious domains. For transactions, it simulates outcomes to detect hidden permissions or differences between what a request displays and what it would authorize. Its checks also cover decentralized applications, smart contracts and unexpected changes to signing requests.

“AI is making cyberattacks cheaper and easier to scale, which means security can no longer rely on known threat lists or a single line of defense,” said Alvin Kan, the wallet’s chief operating officer. He said protection should cover the broader system as self-custodial wallets expand into payments and everyday finance, while preserving users’ control.

Recent cases cited in the report show how wallet approvals can be targeted. On Oct. 5, crypto.news reported that malicious USDG permit signatures linked to Revenue were used to obtain unlimited spending permission, according to security firm Salus. On Nov. 5, Binance co-founder Changpeng Zhao warned about a fake Trust Wallet website. Researcher Anurag said its code could scan balances and prepare transfers to preset addresses for Trust Wallet, Phantom and OKX Wallet; signing was disabled when he examined the site.

Bitget Wallet also lists encrypted private-key storage, multi-party computation, trusted execution environments, biometric authentication, infrastructure isolation, third-party risk assessments and continuous vulnerability monitoring among its safeguards. The company said it plans to expand AI-driven detection and explore AI-assisted incident response under human oversight.
