How does it infect the computer?

Computers can easily get infected with Trojan:BAT/QuasarRAT.RP!MTB if the user often visits sites that are engaging in the illicit distribution of movies, music, and program installer files. More so if they download software that is packed with malware. For instance, attackers can easily bundle legitimate freeware with malicious code and make it appear that it is unmodified, retaining the same name, icon, and description. The only thing they cannot hide is the difference in file size. Off course, the modified one reveals an increase in kilobytes.

Spam email messages are also a channel for the distribution of Trojan:BAT/QuasarRAT.RP!MTB. Attackers usually mislead the recipient by pretending to be from a legitimate organization. They also made the subject and content attractive, which may entice the user to open it and click on the attached file. The moment that file is run, Trojan:BAT/QuasarRAT.RP!MTB begins the attack by dropping malicious files on the Windows folder.

How does this malware operate?

Trojan:BAT/QuasarRAT.RP!MTB is a computer malware that was made solely to control the infected computer. Therefore, the moment that it infects the computer, it drops malicious files in the Windows system folder. It then scans the device for vulnerabilities and exploits them to further loosen the security configuration, including disabling antivirus and firewall. Trojan:BAT/QuasarRAT.RP!MTB is able to download and install a client version of a Quasar Remote Administration Tool and set it up so that the attackers may be able to remotely control the compromised computer.

If Trojan:BAT/QuasarRAT.RP!MTB is fully functional on the infected computer; the attackers may be able to perform the following malicious actions:
