Cybersecurity: Gmail delegation and digital fraud risks

Users are advised to review their Gmail settings to ensure unauthorized individuals do not have access to their personal information. A legitimate feature known as ‘email delegation’ allows others to read, send, and delete emails without needing the account owner's password. While intended for assistants or colleagues, access granted years ago may have been forgotten, meaning changing a password alone will not revoke the delegated access.

In broader cybersecurity contexts, businesses face various digital threats including spoofing, where attackers falsify sender information to appear as known contacts, and phishing, which uses deceptive links to steal credentials. Additionally, ransomware can encrypt critical company files, and social engineering tactics are used to manipulate employees into granting system access. Security experts recommend using two-factor authentication, maintaining regular backups, and carefully verifying sender addresses to mitigate these risks.
