The digital world we live in allows us to go online using various devices. However, this has created a chance for unauthorized remote access from people with malicious intent. This is what is referred to as a backdoor in cyber security. Just like a burglar who breaks into your home, hackers break into your device and access sensitive information. These backdoor attacks are motivated by surveillance, data theft, sabotage, cryptojacking, and malware attacks, among others.
Understanding a Backdoor Attack
You might be wondering what a backdoor in cyber security is, especially after acquiring a device. Usually, devices don’t come equipped with backdoors, but hackers can install a backdoor into a device. This can be done using malware, accessing the device’s firmware, or exploiting software vulnerabilities. Depending on the target, backdoor attackers may try to steal data and gain access to the network for more malicious reasons.
Types of Backdoors
Different backdoors can be used to access various devices, as each backdoor follows a specific attack. Let’s look at the types of backdoors to help you differentiate them.
A Cryptographic Backdoor
A cryptographic backdoor uses a tool that’s similar to a master key, providing access to all encrypted data on a device. Data is usually protected by various algorithms, such as AES 256-bit encryption. The key decrypts the security encryption, providing access to the data within. This type of backdoor attack breaches the security, allowing hackers to bypass the security’s encryption.
Hardware Backdoors
Another backdoor in computer security is hardware. This entails altering a component of the device, whether hard drives, CPUs, computer chips, or other elements. This attack provides hackers with access to the device and other vital systems. Non-computer hardware, such as home security systems, phones, and thermostats, can also be altered, providing access to data. The primary goal of a hardware backdoor is surveillance through remote access.
Trojan Backdoor
The most popular backdoor attack in cyber security is a Trojan backdoor. As the name suggests, it comes from the Greek wooden Trojan horse that was used to attack the City of Troy. Like the legend, a Trojan backdoor infiltrates the system disguised as trusted files to spread malware. Once these malicious files are introduced to the system, pop-up messages that usually read “insert program here” will appear and make changes to the device. This is one of the most dangerous attacks, as it provides hackers access without restriction.
Now that you know the definition of a backdoor in cyber security and the various types of attacks, you can take measures to prevent such issues. Contact us at Jett Business Technology and schedule a consultation to ensure optimum cyber security in Marietta.
