Red Balloon has discovered critical architectural vulnerabilities in the Siemens SIMATIC and SIPLUS S7-1500 series that allow for bypass of all protected boot features.
Red Balloon discovered a vulnerability which allows an attacker to persistently bypass Cisco's proprietary secure boot mechanism and lock out future updates.
Red Balloon provided embedded defense to protection relays, RTUs and network equipment to increase device protection, detect attacks and bring device level forensics.
