Trojans can be used for data deletion, copying or formatting disks. In many cases, hackers just want a backdoor, which can be created easily with a trojan file, to keep an eye on activities. Trojans also work by downloading and installing other kinds of malware, such as ransomware. Also, hacker may use the infected device as a botnet and carry on illegal work. Remote access to systems & devices, and keystroke logging, are other reasons why trojans are popular with cybercriminals.
