Cybercrime, web shell attacks on servers continue to grow

Cybercrime web shell attacks continue to rise. Microsoft cybersecurity experts: It may be attributed to how simple and effective they can be. Attackers exploit vulnerabilities in web applications

Cybercrime web shell attacks continue to rise. It has been denounced by Microsoft cybersecurity experts. The latest data shows that every month from August 2020 to January 2021, researchers registered an average of 140,000 encounters of these threats on servers, almost double the 77,000 monthly average last year. It may be attributed to how simple and effective they can be for attackers, who take advantage of vulnerabilities in web applications. A web shell is a small piece of malicious code written in typical web development programming languages, that attackers implant on web servers to provide remote access and code execution to server functions. It allows to run commands on servers to steal data or use the server as launch pad for other activities like credential theft, lateral movement, deployment of additional payloads, or hands-on-keyboard activity, while allowing to persist in an affected organization.
