| Description | (Arbor) Ismdoor has an encrypted configuration that contains a primary and secondary C2 domain, various identifiers, timeouts, and flags. These values can be updated by later C2 commands. A substitution cipher is used to decrypt the configuration when it is needed. The character mapping has been consistent across samples and we have made available a Python snippet of it on Github. | |
