A Man-in-the-Middle (MITM) cyber attack is where a hacker intercepts communication between two parties and alters or steals the information being transmitted, without either party knowing. This potentially allows the attacker to steal information being exchanged, such as login credentials, payment details, or confidential business data.
This attack works by intercepting communication between two parties and impersonating one of them, which can be done by creating a fake access point or by compromising an existing one.
The attacker essentially positions themselves as a “middleman,” controlling the communication flow. For SMEs, this could mean serious data breaches, financial losses, and reputational damage.
SMEs often lack robust cybersecurity infrastructure compared to large enterprises. This makes them low-hanging fruit for attackers who exploit poor network security, outdated software, or inadequate employee training. Additionally, SMEs handle sensitive customer information, financial data, and proprietary business information, making them valuable targets.
To stay safe from these attacks, prioritise strong passwords and multi-factor authentication, make sure websites that you visit use HTTPS which encrypts data sent between you and the website, and avoid using public Wi-Fi as these networks are often unsecured.
