(TS//SI//REL) SOUFFLETROUGH is a BIOS persistence implant for Juniper SSG 500 and SSG 300 series firewalls (320M, 350M, 520, 550, 520M, 550M). It persists DNT’s BANANAGLEE software implant and modifies the Juniper firewall’s operating system (ScreenOS) at boot time. If BANANAGLEE support is not available for the booting operating system, it can install a Persistent Backdoor (PBD) designed to work with BANANAGLEE’s communications structure, so that full access can be reacquired at a later time. It takes advantage of Intel’s System Management Mode for enhanced reliability and covertness. The PDB is also able to beacon home, and is fully configurable.
(TS//SI//REL) A typical SOUFFLETROUGH deployment on a target firewall with an exfiltration path to the Remote Operations Center (ROC) is shown above. SOUFFLETROUGH is remotely upgradeable and is also remotely installable provided BANANAGLEE is already on the firewall of interest.


Status: (C//REL) Released. Has been deployed. There are no availability restrictions preventing ongoing deployments.
Unit Cost: $0
