None of that makes the malware exceptional, however. Instead, it's the nature of the payloads that it downloads. You see, while other malware downloads viruses and other horrible exploits, Wifatch installs security patches, terminates insecure services, such as telnet, and eliminates any other malware infections it might find. It also alerts users to update their firmware and change their passwords. In other words, Wifatch seems to be working to make infected systems more secure.
