Their key difference is the target Mac OS architecture. The activity of this malicious program has been recorded in various countries, but mainly in the United States, Canada, United Kingdom, Germany, and France. Security researchers have classified Silver Sparrow as backdoor. Backdoor is a type of malware that gives cybercriminals unauthorized access to a computer. Using this malware, attackers are able to control Mac computers, download and install other malicious software, and steal user’s personal data.

The second variant of this virus infects the latest Mac computers based on M1 processors. The latter is newer and therefore less common. As mentioned above, this malware is a backdoor, but at the time of research, Silver Sparrow was not downloading any malware to the infected computer. It is not known exactly when the malware will activate, but it can happen at any time. Silver Sparrow has made in such a way that its code can be changed at any time. And more importantly, it uses Amazon AWS for malicious purposes. This malware is able to use this service to spread malware.
 

Silver Sparrow malware (variant 2)

Malware that has backdoor capabilities can spread different types of malicious programs. For example, ransomware, Trojans, adware, browser hijacker, potentially unwanted applications and spyware. The most dangerous is ransomware. Ransomware is a malicious program designed to encrypt a user’s files and demand ransom for decrypting them. Trojans are similar to backdoors and allow attackers to take control of infected computers. Adware is a form of malware that displays endless advertisements on an infected computer. Adware can also change browser settings and redirect the browser to misleading and malicious websites. To summarize, Silver Sparrow can potentially infect the computer with a variety of malicious programs, which can lead to theft of personal information, financial losses, device damage.
