The backdoor attack is a type of malware that is used to get unauthorized access to a website by the cybercriminals. The cybercriminals spread the malware in the system through unsecured points of entry, such as outdated plug-ins or input fields. The malware is entered in the system through the backdoor and it makes it ways to the company’s sensitive data including customer personally identifiable information.

Smaller and middle-sized businesses are usually attacked by the backdoor attack as they have fewer resources to close off entry points and identify successful attacks. SMBs often lack resources like budget and security experts to prevent and mitigate attacks. In backdoor attacks, the business usually remains unaware of the attack as the name suggests the attack is made from the backdoor. 

The Consequences of Backdoor Attacks on Small Businesses

Small businesses are always at high risk of security breaches or attacks. They need to take proactive measures to secure their websites and prevent backdoor attacks to avoid the financial fallout of successful breaches. A data breach cost may exceed $100,000 for smaller businesses that do not include a high price tag with repairing reputation and rebuilding customer trust.

Backdoor attacks have been increased in the last two years as the problem is getting worse as detecting it is becoming more difficult. Cybercriminals are using different new techniques and strains of malware that can bypass malware scanners easily without detection. The more a malware remains undetected in a system the more damage it causes to the business. 

How to Prevent Backdoor Attacks

Business owners can use website scanners to defend themselves against backdoor attacks. The website scanners mitigate malware, patch vulnerabilities and alert the administrator against threats. 

Make sure your cybersecurity team performs adequate research to detect and review new types of malware daily. They are using updated tools to detect malware. Install a web application firewall to protect your website from malicious actors.
