Hypertext Markup Language – HTML for short – is used to create and structure content presented online. This often happens in e-mail communication as well. But one can assume that practical, well thought-out technologies are usually also very popular with criminals. And in fact, HTML is an overly welcome attack tool in phishing, for example to disguise the theft of login data. Even more:…
