Fancy Bear Source Code

This repo contains actual source code found during IR. The code provides a communication channel for the attacker and infected client. It uses Google's gmail servers to send and receive encoded messages.

Some artifacts are summorized below

• Comments are in english, with a lot of grammar mistakes
• Subject of an email is: 'piradi nomeri'. This means Personal Number in Georgian
• It saves files with **detaluri_**timetsamp.dat. 'Detaluri' is also Georgian for "details".
• In the email body it uses the word: "gamarjoba". Meaning 'Hello' in Georgian.

These are the Gmail account details used, I've verified they once worked (but not anymore!)

• POP3_MAIL_IP = 'pop.gmail.com'
• POP3_PORT = 995
• POP3_ADDR = '[email protected]'
• POP3_PASS = '30Jass11'
• SMTP_MAIL_IP = 'smtp.gmail.com'
• SMTP_PORT = 587
• SMTP_TO_ADDR = '[email protected]'
• SMTP_FROM_ADDR = '[email protected]'
• SMTP_PASS = '75Gina75'

Command and Control server

• XAS_IP = '104.152.187.66'
• XAS_GATE = '/updates/'

The code is completely left as found on the original server, including the log files.

ESET has the complete source code of XAgent, read their report here: http://www.welivesecurity.com/wp-content/uploads/2016/10/eset-sednit-part-2.pdf
