A phishing attack is a digital identity theft. Hackers send fraudulent emails which, for example, imitate the look of well-known online service providers such as Amazon or PayPal or of well-known banks. If the personal data requested is entered on the phishing website, it is sent directly to the cyber criminals.
With the help of link tracking and other techniques, the spam filter service effectively protects users from phishing emails. Among other things, reloadable malicious script commands are detected. This enables detection of dangerous drive-by downloads, for example.
