2. Backdoor and DoS attacks
A backdoor attack bypasses security controls and login mechanisms to gain access to a computer system or encrypted data. The attack bypasses the secure login authentication process, allowing access to applications, networks, or devices containing sensitive information. It also allows attackers to remotely execute commands and perform malware updates.
Backdoor attacks can lead to denial-of-service (DoS) attacks and other malicious activities. In a DoS attack, the attacker floods the target system or network with unusual traffic, causing the service to be temporarily or permanently unavailable to users. When this technique is used to hack multiple devices (such as laptops or smartphones) on a corporate network, it is called a DDoS attack.
Other types of backdoor attacks include:
Built-in Backdoor: A backdoor is used in software development to allow development teams to directly access the code for debugging. Cybercriminals can exploit these backdoors to hack systems and access sensitive data or install viruses on devices running the software.
Trojan Backdoor: A malicious software program that, once downloaded, allows attackers to gain unauthorized access to the system. It is specifically designed for hacking high-security systems and resources.
Tips for preventing backdoor attacks:
Have your devices checked regularly, especially if sensitive data is stored or processed on them
Use a firewall and antivirus software for all devices and systems and always keep them up to date
Use an anti-malware tool
3. DNS attacks
The Domain Name System (DNS) is like a phone book that turns machine-readable IP addresses into human-readable URLs, making DNS both a critical component for businesses and a prime target for cyberattacks.
In a DNS attack, the attacker compromises the Domain Name System (DNS) to gain access uae telegram data to the network and steal or destroy information. The following types of cyberattacks include DNS security threats:
DNS tunneling: Attackers use a DNS resolver to create a tunnel between themselves and the victim, allowing the malware to bypass security controls.
Domain generation algorithms: Attackers generate new domains and IP addresses once security software blocks the previous ones. This allows them to continue to carry out attacks and bypass security mechanisms.
Fast Flux: Attackers use multiple fake domains and IP addresses to confuse and bypass IP controls and penetrate a secure network.
Newly registered domains: Attackers create variations of existing domains to mislead users. These domains only exist for a short period of time and are therefore difficult to detect.
Tips for preventing DNS attacks:
Perform checks on your DNS zones
Update your DNS servers
Restrict DNS servers for zone transfers, i.e. the transfer of zones to another server.
