"Our Web-Based PLC malware resides in PLC memory, but ultimately gets executed client-side by various browser-equipped devices throughout the ICS environment. From there, the malware uses ambient browser-based credentials to interact with the PLC's legitimate web APIs to attack the underlying real-world machinery," the researchers explained. "While previous attacks on PLCs infect either the control logic or firmware portions of PLC computation, our proposed malware exclusively infects the web application hosted by the emerging embedded webservers within the PLCs," the researchers noted.
In this Help Net Security video, Michelle Alvarez, Strategic Threat Analysis Manager at IBM X-Force, discusses the 2024 X-Force Threat Intelligence Index, revealing top threats and trends the team observed last year across its global engagements and how these shifts are forming the threat landscape in 2024 and beyond.
