A Man-in-the-Middle (MITM) attack occurs when a malicious actor intercepts communication between two parties without their knowledge. In a business context, this can have severe implications: Data Interception MITM attackers can intercept sensitive information such as login credentials, financial data, or proprietary company information being transmitted between employees, clients, or partners. Information Tampering They can alter the information being exchanged. For instance, modifying payment details in a financial transaction or changing the content of emails or documents, leading to incorrect decisions or financial loss. Business Email Compromise MITM attacks can be a part of larger schemes like Business Email Compromise (BEC), where attackers intercept emails between employees or executives to manipulate transactions or redirect funds. Reputational Damage Breaches resulting from MITM attacks can damage a company's reputation, erode customer trust, and lead to legal consequences, especially if customer data is compromised. Intellectual Property Theft If sensitive business plans, product designs, or proprietary information is intercepted and stolen, it can significantly harm the competitive advantage of the business. Network Vulnerabilities MITM attacks might lead to the installation of malware, providing attackers with persistent access to a company's network or systems for further exploitation. To mitigate MITM threats, businesses should implement robust cybersecurity measures: Encryption Use encrypted communication channels (e.g., HTTPS, VPNs) to protect data from interception and tampering. Network Security Regularly update network security protocols, utilise firewalls, and employ intrusion detection systems to detect and prevent unauthorised access. Employee Training Educate employees about cybersecurity best practices, including recognising suspicious emails, avoiding insecure Wi-Fi for sensitive transactions, and using strong passwords.
