SparrowDoor

Description

(ESET) The connections could be either through a proxy or not, and they connect to the C&C server over port 443 (HTTPS). So, the communication should be encrypted using TLS. During the first attempt to contact the C&C server, SparrowDoor checks whether a connection can be established without using a proxy, and if it can’t, then the data is sent through a proxy. All outgoing data is encrypted using the XOR key hH7@83#mi and all incoming data is decrypted using the XOR key h*^4hFa. The data has a structure that starts with a Command ID, followed by the length of the ensuing encrypted data, followed by the encrypted data.
