The diffusion of technology in our society has an important consequence.
We’ve adopted the technology elements so rapidly in our daily lives – without even understanding the implications of how our own daily life routine can be used against us.
In the today’s business environment, enterprises are also turning into a fascinating target for attackers, thanks to the network security flaws in their networks. With the cyberattacks coming from nearly all sides, it is difficult to ensure that every vector and point of entry within a network is well protected.
We all know that we are encircled by millions of electronic devices and appliances that in many cases perform vital functions in areas such as telecommunications, healthcare and defense. But any one of these devices could easily be equipped with a software or hardware backdoor that can cause a serious outcome for us. To safeguard against such threats, we must focus on validating the software and electronic components present in these devices.
A Backdoor is basically a remote administration utility that permits a user to gain access and control of a system — remotely over a network or the Internet. A backdoor can easily get the access & control of a system — because it exploits the undocumented processes in the system’s code. And a backdoor can be enforced for two reasons – either for getting the legitimate access of a system by the system administrator himself or as an unauthorized access by attackers who wants to control user’s machine without their knowledge and authorization.
A typical backdoor consists of 2 components – the client and its server(s). An attacker can use a client application to communicate with the server components, which are installed on the victim’s system. Where, the server components can be delivered to the victim’s system in numerous ways – in the format of a malware, trojan payload or a malicious e-mail attachment, etc.
An infected or vulnerable server component opens a network port to communicate with the client. An attacker can use this backdoor to issue commands to the infected system. Depending on how sophisticated the client is, it can include such features as:
While the Backdoors aren’t limited to software, they can also affect hardware and embedded radio-frequency identification (RFID) chips and memory.
Common hardware backdoors attacks embrace such features as:
Recently, we have seen a rise in Backdoor attacks, here are the most significant ones:
It is very important to understand the causes and consequences of a present backdoor in your devices. Be proactive and minimize the likelihood of a backdoor situation so you can stay in business without interruption. At present, there many of these backdoors elude malware detection tools because there are no executables, Enterprises must now look for new ways to track the open-source projects that enter their enterprise from external untrusted sources, such as open-source code repositories and must be able to rapidly respond to any backdoors discovered in these projects. If not, these backdoors have the potential to inflict serious and prolonged harm to the enterprise.
