CoolWallet has introduced enhanced transaction confirmation functionality to prevent Bybit-style hacking attacks

Recently, Bybit fell victim to a hacker attack, resulting in a $1.5 billion Ethereum loss, exposing a security vulnerability in Multisig Wallets. Through an interface manipulation attack, the hacker deceived transaction signers, ultimately stealing 401,346 ETH (approximately $1.46 billion). This attack method allowed the hacker to modify transaction details, causing users to unknowingly sign malicious transactions, resulting in significant asset losses.
To enhance transaction security, CoolWallet has introduced a new "Transaction Confirmation Simulation" feature, available for CoolWallet Pro, CoolWallet S, and CoolWallet HOT users. This feature allows users to preview on-chain asset changes in full before signing transactions, ensuring the transaction aligns with expectations and effectively guarding against malicious attacks.

Key Advantages of CoolWallet's Transaction Confirmation Feature
· Full Asset Change Preview – Instantly preview all asset changes before signing a transaction, including the actual amount sent, receiving address, etc., to ensure the transaction content is correct and to avoid signing unclear transactions.
· Anomaly Detection – Compare expected and actual transactions, identify suspicious behavior, and alert users.
· Real-time Alerts – Notify users of abnormal transactions through push notifications or instant messages to ensure they can react before the transaction is completed.
This feature can effectively prevent transaction risks caused by blind signing. Hackers often exploit interface manipulation attacks or smart contract vulnerabilities to trick transaction signers into approving malicious transactions without their knowledge, resulting in asset losses. Through CoolWallet's enhanced transaction preview feature, users can clearly see the actual impact of a transaction before signing, ensuring the transaction content meets expectations, promptly detecting anomalies, and avoiding potential security threats.
CoolWallet Enhances Security: Boosted by Smart Scan Technology
In addition to strengthening the transaction confirmation feature, CoolWallet has partnered with Blockaid to introduce Smart Scan intelligent scanning technology, providing additional security protection:
· Instant transaction scans to prevent phishing attacks and malicious smart contracts
· Analyzing transaction risks, flagging suspicious behavior, and automatically alerting users to risk information
· Seamlessly integrate DeFi protocols and Web3 applications, without affecting user experience, providing real-time transaction security analysis
Enhance Blockchain Security Standards to Safeguard User Assets
While CoolWallet's transaction confirmation simulation and Smart Scan technology provide users with a more robust transaction security guarantee, the real key to preventing hacks still depends on users' own security habits. CoolWallet recommends all users:
· Use a hardware wallet to store high-value cryptocurrency assets.
· Enable Multi-Factor Authentication (MFA) to protect exchange account security.
· Regularly update security tools, increase awareness of hacking, and guard against new attack methods.
Increasing security awareness is the fundamental key to preventing hacker attacks. CoolWallet urges all users to immediately upgrade their software to enjoy the latest security features and ensure worry-free asset security.
