What you need to know about Spam & Malware

Cybercriminals use spam messages in forms on websites, online forums, and e-mail to spread malware undetected. Depending on the kind of malware, it injects itself into the affected user systems or directly onto the web server of the online service to steal sensitive data, destroy files, and infect other systems.

The most common types of Spam & Malware attacks are:

Form spam refers to the sending of unsolicited messages via the contact forms of online portals. These annoying messages often contain links to malicious websites or contain infected file attachments. The latter are often uploaded by cybercriminals in job application forms, with scammers hiding the malware in job application documents. Once injected into the systems of victims, malware can inflict considerable damage.
