Night Dragon attacks

Summary

McAfee uncovered a major string of attacks designed to steal sensitive data from targeted organizations. McAfee has named these attacks Night Dragon.

McAfee has added Night Dragon protection (and protection to similar threats) to its security solutions. For the best defense against Night Dragon and other attacks, McAfee recommends you use its latest endpoint and network solutions, with updated signatures and Global Threat Intelligence (GTI) enabled. Although Night Dragon attacks are not linked to Operation Aurora (http://www.mcafee.com/us/threat-center/operation-aurora.aspx), both are Advanced Persistent Threats (APTs). APTs combine social engineering with well-coordinated, targeted, cyber-attacks using Trojans, remote control software, and other malware. 

Attack Details
Night Dragon attacks use coordinated, covert, and targeted cyber-attacks involving: social engineering, spear phishing, vulnerability exploits in the Windows operating system, Active Directory compromises, and Remote Administration Tools (RATs).

The Night Dragon attack sequence is as follows:
  1. Compromise public-facing web servers via SQL injection; install malware and RATs.
  2. Use the compromised web servers to stage attacks on internal targets.
  3. Launch spear-phishing attacks on mobile worker laptops to compromise VPN-connected accounts and gain additional internal access.
  4. Use password stealing tools to access other systems and install RATs and malware in the process.
  5. Target computers that belong to executives to capture their email and files.
How can you find out if you are infected?
Update your DAT files to the latest version, ensure On-Demand Scans are working properly, and perform a full file system virus scan. Review ePolicy Orchestrator (ePO) anti-virus alerts and network logs to identify compromised systems. The first DAT version to detect Night Dragon is 6232.

McAfee tools to assist you:

Is network / intrusion detection available?
Yes. Monitor network communications for the following string, which indicates an infected computer is sending a "beacon" to a Command and Control (C&C) Server:

\x01\x50\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x68\x57\x24\x13

Can you find Night Dragon without computer forensics?
Yes. The DLL is a Hidden or System file attribute and can be found by size (19-23 KB). It is usually located in the C:\Windows\System32 or C:\Windows\SysWow64 directory.
Additional artifacts exist on the file system that can identify when the dropper installed the backdoor DLL and what types of activities the attacker conducted (for example, Remote Desktop and the Command Shell).


If you find Night Dragon, do you need to worry about it infecting other computers?
No. Night Dragon is a Trojan backdoor. It has no Worm infection capability and does not self-propagate. Attackers typically install Night Dragon on different computers using a Trojan dropper file (.exe) on a Windows share.


How do McAfee products combat Night Dragon?
APTs are sophisticated, multi-faceted attacks that require a coordinated and well-architected defense. McAfee has added Night Dragon protection to all products using DAT files, and specifically to the following point products:
