Examples of Man-in-the-Middle Attacks
MiTM attacks can cause serious harm to organizations and the public.
A 2017 MiTM attack on Equifax resulted when threat actors exploited an HTTP error to intercept traffic to the Equifax servers. The attack compromised the sensitive information of 143 million American consumers.
In 2019, a Chinese venture capital firm and an Israeli startup faced a MiTM attack in which the cybercriminals stole about $1 million of startup funds. The perpetrators intercepted email communications between the two firms and rerouted the seed money for the startup to their accounts.
How to Detect and Prevent Man-in-the-Middle Attacks
Symptoms of MiTM attacks include repeated and unexpected disruption of any particular service in an organization’s network and abnormal website links being accessed. Organizations can monitor and protect their networks by implementing proper cybersecurity solutions.
ZTNA ensures that all users and devices are constantly authenticated and authorized before entering a network and acquiring any resources. By reducing the possibility of cyber attackers accessing a network, ZTNA strengthens an organization’s security.
Endpoint security protects devices—desktops, laptops, and smartphones—from various cyber threats. As MiTM attacks target IoT devices, employing detection and response systems, threat hunting, data safeguarding, and other endpoint security features is a vital and comprehensive security measure.
Security Awareness and Training
Creating robust security policies is a proactive way to prevent MiTM attacks from harming an organization. Organizations can reduce the likelihood of security risks by enhancing employees’ knowledge and understanding of cyber threats, phishing attacks, online safety, and other social engineering techniques.
MDR solutions provide continuous monitoring, threat detection, and rapid response capabilities. This security measure reduces the impact and possibility of cyber attacks and strengthens an organization’s cyber defenses.
