Backdoor.Sacto is a backdoor Trojan that opens a back door and steals information from the corrupted PC. Once run, Backdoor.Sacto creates the malevolent files. Backdoor.Sacto then creates the particular link so that it can load automatically whenever you start Windows. Backdoor.Sacto may connect to any of the URLs. Backdoor.Sacto then grabs information, which covers security certificates from the compromised PC and transfers it to the remote cybercriminal.
