Bankr Halts Transactions After Hack Hits 14 Wallets, $150K Lost
AI-powered crypto trading assistant Bankr has temporarily shut down all transaction functions after a hacker reportedly gained access to 14 wallets. Users claim losses of up to $150,000 in cryptocurrency per wallet, prompting the platform to initiate an investigation and promise full reimbursement for affected funds.
In a statement posted on X (formerly Twitter) on May 19, Bankr said it had identified the unauthorized access and disabled all transaction capabilities, including swaps, transfers, and token deployments, "out of caution" while the breach is examined. The platform also advised users to refrain from signing any transactions and to migrate assets to new wallets if their existing ones were compromised.
AI-Agent Vulnerabilities Resurface
Bankr operates as an AI agent that allows users to trade, transfer, and deploy tokens using natural language commands. It automatically creates a crypto wallet for any X handle interacting with its bot, a feature that has previously been exploited. Earlier this month, a similar attack on Bankr resulted in the loss of $174,000 worth of tokens on the Base network. That exploit leveraged a prompt injection attack, where hackers embedded malicious Morse code instructions within social media content to trick the AI into executing unauthorized transfers.
Security researchers have raised concerns over the systemic risks posed by AI-agent-based crypto tools, particularly when natural language inputs directly trigger irreversible blockchain transactions. Analysts recommend stricter transaction approval mechanisms, such as human-in-the-loop confirmations, transaction thresholds, and enhanced filtering for obfuscated prompts.
Escalating Crypto Hacks in 2026
The Bankr breach is the latest in a string of high-profile crypto hacks in 2026. In April alone, hackers exploited Drift Protocol for $280 million and Kelp Protocol for $292 million, ranking as the two largest crypto thefts of the year. Overall, more than $168.6 million in crypto was stolen in the first quarter of 2026, according to industry reports.
Bankr's hack also follows a broader trend of targeting AI-driven platforms, which are increasingly integrated into financial services but often lack the security maturity of traditional systems. Crypto trading AI tools like Bankr, which simplify user interactions through automation, are particularly attractive targets due to the direct access they provide to on-chain assets.
Bankr’s Response and User Guidance
Bankr has pledged to reimburse all affected users and is actively investigating the breach. In the meantime, the platform issued specific guidance for those impacted: create a new wallet on a clean device, transfer any remaining tokens or NFTs, and revoke wallet approvals if assets cannot be moved. Additionally, Bankr recommended scanning devices for malware or suspicious browser extensions, particularly for those using software wallets.
Austen Allred, a tech entrepreneur, reported that a Bankr wallet linked to his Kelly Claude AI assistant project was among those compromised. While Ether (ETH) was stolen, the associated memecoin stash remained untouched. Allred noted that there was "no evidence anyone other than myself ever logged into the Bankr account," suggesting the attacker accessed keys through other means.
Key Takeaways
Bankr's ongoing investigation highlights the evolving risks in integrating AI with blockchain systems, particularly in the absence of robust security protocols. For traders, the incident serves as a warning to exercise caution with automated tools and to frequently audit wallet permissions. As AI continues to reshape crypto trading, security frameworks must keep pace to prevent further high-value exploits.
The market will be closely watching Bankr’s response and whether its promised reimbursements restore user confidence. Meanwhile, the broader industry faces increasing pressure to address the vulnerabilities exposed by these AI-agent breaches.
