Parent class: TrojWare
Trojans are malicious programs that perform actions which are not authorized by the user: they delete, block, modify or copy data, and they disrupt the performance of computers or computer networks. Unlike viruses and worms, the threats that fall into this category are unable to make copies of themselves or self-replicate. Trojans are classified according to the type of action they perform on an infected computer.Class: Backdoor
Backdoors are designed to give malicious users remote control over an infected computer. In terms of functionality, Backdoors are similar to many administration systems designed and distributed by software developers. These types of malicious programs make it possible to do anything the author wants on the infected computer: send and receive files, launch files or delete them, display messages, delete data, reboot the computer, etc. The programs in this category are often used in order to unite a group of victim computers and form a botnet or zombie network. This gives malicious users centralized control over an army of infected computers which can then be used for criminal purposes. There is also a group of Backdoors which are capable of spreading via networks and infecting other computers as Net-Worms do. The difference is that such Backdoors do not spread automatically (as Net-Worms do), but only upon a special “command” from the malicious user that controls them.Read more
Platform: Win32
Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.Description
Backdoor.Rbot is a family of Trojan programs for Windows, which offer the user remote access to victim machines. The Trojans are controlled via IRC, and have the following functions:
monitor networks for interesting data packets (i.e. those containing passwords to FTP servers, and e-payment systems such as PayPal etc.)
scan networks for machines which have unpatched common vulnerabilties (RPC DCOM, UPnP, WebDAV and others); for machines infected by Trojan programs (Backdoor.Optix, Backdoor.NetDevil, Backdoor.SubSeven and others) and by the Trojan components of worms (I-Worm.Mydoom, I-Worm.Bagle); for machines with weak system passwords
conduct DoS attacks
launch SOCKS and HTTP servers on infected machines
- send the user of the program detailed information about the victim machine, including passwords to a range of computer games
Every 50 milliseconds the backdoor creates a thread in which it will connect to the following server (if there is a network accessible):
www.starman.ee www.if.ee
If in the course of 256 connection either of the servers returns an error saying that the resource is temporarily not available, the connection will be suspended for half a second.
The backdoor spreads via the Microsoft Windows DCOM RPC vulnerability. A full description of the vulnerability can be found in Microsoft Security Bulletin MS03-026 Microsoft Security Bulletin MS03-026 (
The backdoor chooses IP addresses to attack, and if a machine under attack contains the DCOM RPC vulnerability, the backdoor will launch its code on the vulnerable machine.
If none of the computers under attack contain this vulnerability, the backdoor will try to connect using the following user names:
Administrator Admin
and the following passwords:
Admin root asdfgh password 00 000 0000 00000 000000 0000000 00000000 1 12 123 1234 12345 123456 1234567 12345678 123456789 secret secure security setup shadow shit sql super sys system abc123 access adm alpha anon anonymous backdoor backup beta bin coffee computer crew database debug default demo X go guest hello install internet login mail manager money monitor network new newpass nick nobody nopass oracle pass passwd server poiuytre private public qwerty random real remote ruler telnet temp test test1 test2 visitor windows
If the backdoor manages to establish a connection, it will copy its executable file to the Windows system directory on the victim machine.
