Backdoor:Win32/Bifrose is a backdoor trojan that connects to a remote IP address using either TCP port 81 or a random port. It allows an attacker to access the computer.
The Bifrose trojan family is highly configurable. Thus, the locations of their installed files on an infected computer and the TCP ports they use to connect may vary. They allow an attacker to perform any of the following actions on the affected machine:
- Manage running processes
- Manipulate files or registry data
- Obtain installed program details
- Log keystrokes
- Screen capturing
- System shutdown or reboot
- Command shell
