“Fishing mail” likely refers to “phishing mail,” which is a type of cyber attack where attackers try to trick individuals into divulging sensitive information such as usernames, passwords, credit card numbers, or other personal data. Phishing emails often appear to be from legitimate sources such as banks, government agencies, or reputable companies, but they contain links to fake websites or malicious attachments designed to steal information. It’s important to be cautious and skeptical of unexpected emails asking for personal information and to verify the authenticity of any requests before providing sensitive data.
