April 22 – PeckShield monitoring has detected that MacSync Stealer (v1.1.2), a highly destructive malware, is currently active. The malware targets macOS users and steals sensitive data including encrypted wallets, browser credentials, the system keychain, and infrastructure keys (SSH, AWS, K8s). It uses a forged AppleScript system dialog for phishing, displaying a fake “unsupported” error message after exfiltrating data. PeckShield has already shared this Indicator of Compromise (IOC) with its customers promptly. PeckShield urges users to **avoid running unverified macOS scripts** and remain highly vigilant for unexpected system password prompts. If an attack is suspected, take immediate remedial steps: change all infrastructure credentials (SSH, AWS, K8s), invalidate exposed keychains, and migrate encrypted assets to a secure wallet without delay.

On April 22, QCP released a market outlook noting that Bitcoin (BTC) rebounded from an overnight low near $75,000 to around $78,000—but the move reflects **position unwinding rather than a return of confidence**. Risk appetite stabilized after Iran extended its ceasefire, easing concerns over recent escalation, while Federal Reserve Chair Powell’s testimony reaffirmed the central bank’s data-dependent approach without signaling a dovish shift. Macro headwinds, however, remain significant. For crypto, BTC’s rebound is driven by **diminished tail risks, not fundamental improvements**. Open interest has recovered, but funding rates remain negative—indicating new short positions are being added, not long positions capitulating. This keeps the squeeze dynamic intact, though market conviction remains weak. The options market echoes this: front-end volatility sits around 40 vol (low relative to realized volatility), skew still leans toward downside protection, and the term structure

On April 22, GMGN co-founder Haze posted on X (formerly Twitter) that, in response to the recent meme trend on the Ethereum mainnet, the GMGN platform is actively enhancing user experience for Ethereum’s mainnet.

April 22: In a chat with Xiao Feng, Vitalik noted that Ethereum is built on a layered structure—including protocol and application layers. A single layer isn’t sufficient, so Ethereum also prioritizes the hardware layer and security. Vitalik also stressed the importance of system simplicity for Ethereum: excessive complexity can cut down on user and developer participation, and it can lead to a subpar user experience.
