Perception Point’s team of researchers recently investigated a malware attack aimed to bypass threat detection engines. The sophisticated attack was caught by our advanced threat prevention platform; the payload was detected by our next-gen sandboxing technology. Read on to learn more.

The user is prompted to click on the button “View & Download Invoice.” To add legitimacy to the message, a legitimate website is included in the message to serve as an alternative to clicking the button.

It is important to note that the attacker had to first breach the legitimate website in order to host the URL redirect.
Looking at the website code shows that there are m ..
