Bad actors can take advantage of these by using port scanners to explore the web for systems with exposed ports. RDP typically initiates requests via port 3389, which if exposed, can become the gateway for ransomware attacks. Pro tip: If you’re an executive looking to boost phishing awareness among your employees, consider a security awareness training program, which includes various simulations and exercises to boost comprehension.Ī cybercriminal can also deploy ransomware via RDP, a communications protocol that enables IT admins to gain access to systems.

The vast majority of ransomware is delivered via phishing email campaigns. So how is ransomware distributed? Below are the top five ransomware attack vectors. Although the ransomware attack technique seems straightforward, an adversary can engineer it in various and ever-changing ways to bypass security implementations. We’ll also highlight the steps needed to reduce the risk of infiltration. In this piece, we’ll look at five main strategies cybercriminals use to deliver and deploy ransomware.
