There are a number of reasons why the email addresses of Twitter users may be leaked. Some possible reasons include:
Data breaches:One of the most common ways that email addresses are leaked is through data breachesin which hackers gain unauthorized access to a website or database and obtain personal information, including email addresses.
Malware infections:Another way that email addresses may be leaked is through malware infections. If a device becomes infected with malware, the malware may be able to access and exfiltrate personal information, including email addresses.
Phishing attacks:Phishing attacks, which are a type of cybercrime in which attackers attempt to trick users into revealing sensitive information, can also potentially result in the leak of email addresses.
If a user falls victim to a phishing attack and provides their email address as part of the attack, their email address may be made publicly available or sold to third parties.
Social engineering:Social engineering attacks, which are a type of cybercrime in which attackers use psychological manipulation to trick users into revealing sensitive information, can also potentially result in the leak of email addresses.
For example, an attacker may use social engineering techniques to convince a user to reveal their email address.
