Backdoor attacks are real and growing! According to a security report by CrowdStrike, more than 85% of the attacks involved the use of backdoor deployment in 2022 making it a topic of concern for organizations and security experts around the world.

In the last couple of years, cybercriminals have increasingly used backdoors to infiltrate systems and carry out attacks. In fact, backdoor attacks surpassed Ransomware as the top attack type in 2022. This shift in attack tactics has made it even more important for businesses to stay vigilant and take steps to protect their data and systems from the menace of backdoor deployment.

What is a backdoor?

A backdoor is a way to bypass normal authentication procedures and gain access to a computer system, network, or application. Backdoors are often created by attackers who have gained access to a system and want to maintain that access, or by developers who have built in a way to access the system in case of emergency. However, such backdoors can be easily exploited by attackers resulting into a serious security risk. This is why it counts to have a robust identity and access management solution. This will help deploy powerful access privileges and rights. Backdoors can be created by exploiting vulnerabilities in software or hardware, or by using social engineering tactics to trick users into installing malicious software.

How are backdoors used in attacks?

Backdoors can be used in a variety of ways in cyberattacks. For example, attackers can use backdoors to:

• Steal data: Backdoors can be used to steal sensitive data such as financial information, personal information, or intellectual property.
• Install malware: Backdoors can be used to install malware such as viruses, Trojans, or spyware, which can then be used to carry out further attacks.
• Take control: Backdoors can be used to take control of a system or network, allowing attackers to carry out actions such as launching DDoS attacks, sending spam emails, or stealing Cryptocurrency.

Why have backdoor attacks become the top attack type?

The rise of backdoor attacks as a top attack vector is a worrying trend for businesses. Backdoors are often difficult to detect, and once they are in place, they can remain undetected for long periods of time. This makes it easier for hackers to carry out their activities undetected, which can lead to significant damage. There are a few reasons why backdoors have become the top cyberattack types in 2022 surpassing Ransomware attacks:

• Backdoors are stealthy: Backdoors can be difficult to detect, making them an attractive option for cybercriminals who want to maintain access to a system without being noticed.
• Backdoors can be reused: Once a backdoor has been created, it can be used again and again in future attacks, making it a valuable entryway for attackers.
• Backdoors are versatile: Backdoors can be used in a variety of attacks, making them a flexible option for attackers.

How can you protect your business against backdoors?

To protect against backdoors, it is essential to have robust cybersecurity measures in place. This includes keeping software and hardware up-to-date with the latest security patches, implementing strong password policies, and training employees to recognize and avoid social engineering tactics.

In addition, it is important to use advanced cybersecurity tools such as insider threat detection and intrusion detection systems and network monitoring tools that can detect and alert administrators about suspicious/abnormal activities or behaviors. These tools can help to identify and remove backdoors before they can be used to cause damage.

There are several steps you can take to protect your business from backdoor attacks:

• Keep software/OS up to date: Backdoors often exploit vulnerabilities in software, so keeping software up to date with the latest security patches can help to prevent attacks. Vulnerability assessment and penetration testing or VAPT is the key here.
• Use strong passwords: Strong passwords can help to prevent attackers from gaining access to your systems through brute-force attacks.
• Use two-factor authentication: Two-factor authentication adds an extra layer of security by requiring a second form of authentication, such as a code sent to your phone.
• Deploy advanced threat intel: To gain an edge in today’s ever-evolving landscape, it is essential to utilize cutting-edge threat intelligence. This involves utilizing a SIEM solution for advanced threat protection powered by AI and security automation to intelligently and swiftly predict and respond to potential threats.
• Prioritize data privacy and security: It is important to prioritize data security by identifying which data matters most to your organization. Managing and securing databases can be a challenge, but implementing a Zero Trust Security Framework can help stay ahead of threats.
• Understand the mindset of attackers: It is advisable to think like threat actors and understand the tactics and procedures they may use. Attack tactics can differ greatly between industries, so it is important to tailor defenses accordingly. Keep an eye on the recent malware and Ransomware attack news to stay updated.
• Maintain endpoint visibility: Ensure optimum visibility of all mission-critical and connected endpoints, such as mobile devices, IoT devices, and computers. A powerful endpoint security solution can help achieve this.
• Conduct regular security audits and awareness programs: Regular security audits can help to identify any potential vulnerabilities in your systems and take steps to address them. Importantly, conduct regular cybersecurity awareness training and workshops for your employees. 

Takeaway

As the threat landscape continues to evolve, it is essential for businesses and cybersecurity experts to remain vigilant and stay up-to-date with the latest cybersecurity trends and best practices. By taking a proactive approach to cybersecurity, it is possible to mitigate the risk of backdoor attacks and other types of evolving cyber threats. 

As backdoor attacks have surpassed Ransomware attacks as the top breach types in 2022, businesses and security teams ought to take steps such as implementing robust cybersecurity measures, using advanced cybersecurity tools, and staying up-to-date with the latest cybersecurity trends and best practices. With the right approach and managed cyber security services provider at your disposal, it is possible to mitigate the risk of backdoor attacks.
