What is Back Orifice?

Back Orifice – remote administration software created by a member of Cult of the Dead Cow hacking organization

Back Orifice is a remote administration tool that could be used for malicious purposes

Back Orifice, later known as BackOrifice2K, is a remote administration application that was first introduced in 1998 by a hacking organization “Cult of the Dead Cow” member known as Sir Dystic. The developer named the software after Microsoft BlackOffice Server, which is meant to mock the tech giant and point out the flaws in then active MS Windows 9x operating systems. A year later, its next version was presented at the DEF CON 7 hacking convention in Las Vegas.

Written in C++ programming language,^[1] its first versions emerged for Windows 95 and Windows 98, while the 2K version has expanded functionality and was also compatible with then-current versions of the OS – NT, Vista, and XP. Several different versions were released by the developers over the years, although each possesses a wide array of features we describe below.

While initially Back Orifice can be used for remote administration legitimately, there has been plenty of abuse by cybercriminals. If installed without permission, it can serve as a Remote Access Trojan with backdoor and rootkit^[2] capabilities. Malware would allow the attacker to take over the operating system with ease or monitor every action of the computer user.

Since the app would allow remote control, attackers could also use the infected computer as a bot^[3] to spread spam or infect it with numerous other viruses, such as the treacherous ransomware. As a result, users could suffer from severe consequences, including monetary losses, credential leak, or even identity theft.

In other words, you should remove Back Orifice from your system as soon as possible if it arrived without permission, and security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, is preferred for it. Since malware has rootkit capabilities, it might be difficult to delete its remnants. Therefore, we recommend performing an additional scan with FortectIntego that could bring Windows back to a normal state after the elimination.

Back Orifice removal should not be delayed, although it is best not to get infected in the first place. Remember to stay away from high-risk websites, never open suspicious email attachments, patch all the software on the system on time, and ensure that a reputable anti-malware with real-time protection feature is running on the system at all times.

According to security experts,^[2] it's not possible to know when Back Orifice virus attack is taking place, so it's very important to ensure a full system protection. Typically, cyber criminals who monitor this infection is spread via spam e-mails. Once a computer user clicks on the attachment, the virus is executed and roots deep into the system. Consequently, the machine can start working abnormally because hacked may start viewing and modifying the files and registries on your computer.

The Trojan can log your keystrokes, log files, take screen shots and send them to hackers or can simply crash the computer, so Back Orifice removal should not be delayed.
