Open network ports. An open port on a network accepts traffic from remote locations, and as a result, it can create a weak point that can be exploited by hackers. Hackers usually target ports that aren’t in use — this allows them to install backdoors that access your device without any of your software alerting you about the intrusion. This shouldn’t be a problem for most home users because our routers’ ports are closed by default. However, tech savvy-users and small business owners need to be very careful about what ports they keep open and what vulnerabilities those open ports create. Many IT professionals use Shodan to keep their networks as secure as possible.

How does a backdoor virus work?
Backdoor virus integrates into the victim’s system on a very deep level. In contrast to the majority of other viruses, backdoors infiltrate into the computer as a driver. According to the ring hierarchical system, drivers are located on Ring 2 and executed with a bigger priority than the operating system. Anything which runs on Ring 2 can control all processes that are located on Ring 3 and Ring 4, where OS and installed software run. Hence, integrating a virus on such a deep level means getting control of the whole system. Backdoors are just one example among a dozen of other viruses that exploit that ability. A perfect example of a riskware that integrates itself on a driver level is a Mimikatz hack tool.
How to detect backdoor viruses?
The best way to detect such an unpredictable virus is to use anti-malware software. Examples like Microsoft Defender do not suit because of the mentioned reasons. However, the effective detection of backdoor viruses is a hard task, and not every antivirus solution is ready. To get the best protection, you will likely need to have a heuristic detection mechanism in your security tool, and also get updates of detection databases as often as possible. GridinSoft Anti-Malware can offer you both of these privileges: its databases are updated every hour, and it has an On-Run protection feature, which uses the heuristic mechanism to detect malware.
