A newly discovered malware strain called Nimdoor raises alarms through the cryptographic community – in particular for macOS users.
The researchers retraced malicious software to the north-Korean hacking groups supported by the state, which now target cryptocurrency holders with surprisingly sophisticated campaign.
Attackers use social engineering To send false zoom updates via platforms like Telegram and Google Meet, encouraging users to install what seems to be an update of videoconferencing – but is actually a custom -stolen door.
Written in the Obscur Nim Programming Language, Nimdoor is difficult for antivirus tools to detect.
Once installed, it quietly exfiltrates sensitive data such as passwords stored by the browser, telegram session data and Crypto portfolio identification.
He even monitors the contents of the clipboard, looking for seed sentences or wallet addresses.
Malware is resettled whenever it is arrested, which makes it particularly difficult to remove once integrated.
Crypto portfolios are the main target
The rise in malware like Nimdoor reflects an increasing trend: cybercriminals no longer hunt passwords – they go directly for cryptographic wallets.
