As more businesses suffer cyberattacks, it is critical to be both proactive and reactive with cybersecurity. Some cyber threats are easier to detect, and a few preventive measures can go a long way in keeping hackers at bay. Others can be more dangerous – such as backdoor attack, also called backdoor exploit. So, what exactly is a backdoor? Is your company aware of backdoor attacks? In this post, we are sharing the basics for small businesses.
What is a backdoor?
A backdoor is basically a means that hackers use to gain unauthorized access into systems and networked devices. It is just like how a burglar would use a backdoor to steal something from a house. If the burglar is smart enough, he will not ransack the entire house, and there could be a chance that he can use the same backdoor again, bypassing standard security measures on the front, to steal something again. Computer backdoors work in a similar way. Backdoors are typically malicious software, but there are exceptions. For instance, many companies have to create backdoors for certain accounts, devices and networks, in case employees and customers lose their regular access.
How are backdoor attacks launched?
In most cases, backdoor attacks are caused by malware like trojans. The user is tricked into downloading a trojan, which looks like a genuine software. If the user grants admin access, trojan will create a backdoor for the hacker. Backdoors are used for varied reasons, such as to steal data, for hijacking servers, for launching malware attacks, to cause DDoS attacks, and sometimes, even to infect users visiting a website.
Why worry about backdoor attacks?
The biggest problem with backdoor attacks is detection. Businesses often remain unaware that the hacker has launched a backdoor, or is exploiting a security flaw. Even when a backdoor attack is detected, just aligning the device may not be the only solution. However, that’s often the first step. Also, for a long time, a backdoor may go unnoticed, and trojans often have the ability to replicate, just like worms, which means that more devices may continue to get infected.
If your company hasn’t spent on measures to prevent cyberattacks, backdoors may remain a concern. One of the best proactive steps is to scan and test networks and devices on a regular basis. Also, let your employees know of how hackers launch backdoor attacks and ways in which they can be tricked into installing malware.
