Remote SCADA Vulnerabilities Hit Schneider Electric

On Monday, a security researcher published new vulnerabilities affecting remote access to the “NOE 771” devices manufactured by Schneider Electrics, one of the world's largest manufacturer of SCADA system devices. The vulnerabilities prompted the ICS-CERT to issue an alert.

Rubén Santamarta (a.k.a. "Reverse Mode"), a 29-year old European-based independent security researcher who previously showed how to hack into the Large Hadron Collider at CERN, said that he was able to attack these devices remotely after first locating vulnerable NOE 771 devices through the SHODAN search engine and then downloading the firmware from Schneider Electric. After reverse engineering the firmware update, Santamarta found he could load a trojanized firmware update, use non-documented hidden accounts, and use other non-documented functionalities. The trouble is in how the devices access remote access commands.
