Typically, the domain appears to be legitimate at first glance, and the differences may be very subtle and hard to spot (a W that is actually two Vs, a lowercase R and N mimicking an M, or a lowercase L that is actually a capital I).

Phishing attacks have long been a cybersecurity challenge for organizations; today, they are responsible for more than 80% of reported security incidents. According to CISCO's 2021 Cybersecurity Threat Trends report, about 90% of data breaches occur due to phishing. Spear phishing, which is the practice of sending emails that appear to be from a trusted sender in order to induce targets to reveal confidential information, is the most common type of phishing attack, comprising 65% of all phishing attacks.
