Taiwan-based network-attached storage (NAS) maker QNAP urges customers to enable firmware auto-updating on their devices to defend against active attacks. The attackers target a vulnerability patched in December, allowing them to run arbitrary code on vulnerable systems. The warning comes after a wave of attacks targeting Internet-exposed NAS devices with DeadBolt ransomware and asking victims to pay 0.03 bitcoins (approximately $1,100) for a decryption key. The company did not name the threat actors behind these ongoing attacks.”]
