Which ransomware targets Linux devices with AES encryption on QNAP NAS?

• A. Worms
• B. Dharma
• C. eCh0raix
• D. SamSam

Answer: (C)

Ransomware families sometimes specialize in the platforms they attack. The one known for encrypting files on QNAP NAS devices runs on the Linux-based firmware of those devices and uses AES to lock the data. eCh0raix emerged specifically as a threat to QNAP NAS, gaining access to the device and encrypting its files, then demanding payment for decryption. The other options align with different targets or behaviors: Dharma is primarily a Windows-focused ransomware, SamSam targeted Windows servers in enterprises, and “worms” describe a broad class of self-replicating malware rather than a NAS-specific ransomware family. So the ransomware associated with Linux-based QNAP NAS devices using AES encryption is eCh0raix.
