2.2.4.8 Software Backdoors in Computer Systems
As described above, backdoor is a remote program used by intruders to gain unauthorized remote access to a computer system due to a vulnerability in its security
system. Backdoors operate in background mode and are hidden from the user. It is
very similar to known malicious viruses and therefore difficult to find; however, backdoor is one of the most dangerous types of cyberweapons, since it allows intruders
to carry out nearly any possible actions on the infected computer. The intruder can
use backdoor to watch users, control their files remotely, install any additional software, control the entire PC system, and attack other hosts. Software backdoor often
has additional destructive capabilities, such as screenshotting, file infestation, and
encryption. Such parasite is a combination of various secret and safe threats, which
operate autonomously and require no management at all.
Most backdoors are considered by computer security specialists as malware that
has to enter the computer in some way. Nevertheless, some of the parasites don’t
even require special installation actions, as their parts can be integrated into software
operating on a remote host. Programmers sometimes leave such backdoors in their
software products for diagnostics and troubleshooting in order to eliminate possible
issues identified in the future during operation of the designed device. However, this
is the reason hackers easily detect and use them only to penetrate into the system.
Backdoors are often referred to as specific Trojans, viruses, keyloggers, spies,
and remote administration means. They operate in the same manner as the above
virus applications. Nevertheless, their functions and loads are more complex and
dangerous; therefore, they are grouped into a specific category here.
Software backdoors cannot spread and infect the system without the user knowing
about them. Most of these parasites need to be installed manually in combination
with other software. There are four main ways for these hazards to enter the system.
– Unprepared PC users can accidentally install typical backdoors on their
computers. They can come attached to e-mails or from file exchangers. Malicious authors give them unsuspicious names and trick the user unto launching or
opening such file.
– Backdoors are often installed by other parasites, such as viruses, Trojan programs,
or even spy software. In this case, they enter the system without knowledge of or
permission from the user of the infected computer. Some hazards can be manually
installed by hackers who have enough privileges to install software. A small
portion of backdoors can distribute due to using remote systems with certain
vulnerabilities in the security system.
– Several backdoors are already integrated into specific applications. Even legal
programs can be faked by means of remote access functions. The attacking file
