The post North Korean Hackers Target Mac Crypto Wallets with New NimDoor Malware appeared on BitcoinEthereumNews.com. A newly discovered malware strain named NimDoor is raising alarms across the crypto community — especially for users on macOS. Researchers have traced the malware to North Korean state-backed hacking groups, who are now targeting cryptocurrency holders with a surprisingly sophisticated campaign. The attackers use social engineering to send fake Zoom updates via platforms like Telegram and Google Meet, tricking users into installing what seems like a video conferencing update — but is actually a custom-built backdoor. Written in the obscure Nim programming language, NimDoor is difficult for antivirus tools to detect. Once installed, it quietly exfiltrates sensitive data like browser-stored passwords, Telegram session data, and most critically, crypto wallet credentials. It even monitors clipboard content, looking for seed phrases or wallet addresses. The malware reinstalls itself whenever it’s shut down, making it particularly hard to remove once embedded. Crypto Wallets Are the Prime Target The rise of malware like NimDoor reflects a growing trend: cybercriminals aren’t just chasing passwords anymore — they’re going straight for crypto wallets. NimDoor is engineered to target browser-based wallets, insecure key storage, and users who copy and paste sensitive information like private keys or seed phrases. If you’re relying on a browser extension or an exchange wallet, you’re especially at risk. These platforms store data in predictable places — which is exactly what this kind of malware is designed to exploit. While macOS has historically been seen as a more secure operating system, NimDoor proves that no system is immune when attackers are this determined. How to Protect Your Crypto in 2025 As these threats evolve, the best defense remains the same: self-custody combined with strong operational habits — also known as wallet hygiene. Wallet hygiene refers to the daily habits that protect your keys, like how you store seed phrases, copy addresses, and…
