Activating a spam filter is the main way of preventing phishing emails that could fool individuals into passing account details straight into the hands of a hacker.
If left unblocked, phishing emails that look like a regular webpage could be sent directly to an inbox resulting in a user logging into their account normally.
This means hackers are not just limited to account information but can also opt to gain access to usernames, passwords, credit card numbers, bank information, and more.
FBI Special Agent in Charge, Robert Tripp, said: "Attackers are leveraging AI to craft highly convincing voice or video messages and emails to enable fraud schemes against individuals and businesses alike.
Previously it was thought that phishing tools could only be effective by sending suspicious links in emails but Astaroth offers an alternative method.
