Description(SecureWorks) CTU analysis indicates that Bronze Butler primarily targets organizations located in Japan. The threat group has sought unauthorized access to networks of organizations associated with critical infrastructure, heavy industry, manufacturing, and international relations. Secureworks analysts have observed Bronze Bulter exfiltrating the following categories of data:

• Intellectual property related to technology and development
• Product specification
• Sensitive business and sales-related information
• Network and system configuration files
• Email messages and meeting minutes

The focus on intellectual property, product details, and corporate information suggests that the group seeks information that they believe might be of value to competing organizations. The diverse targeting suggests that Bronze Bulter may be tasked by multiple teams or organizations with varying priorities.
ObservedSectors: Critical infrastructure, Defense, Engineering, Government, High-Tech, Industrial, Manufacturing, Media, Technology and International relations.

Operations performedJul 2015Symantec discovered the most recent wave of Tick attacks in July 2015, when the group compromised three different Japanese websites with a Flash (.swf) exploit to mount watering hole attacks. Visitors to these websites were infected with a downloader known as Gofarer (Downloader.Gofarer). Gofarer collects information about the compromised computer and then downloads and installs Daserf.
Apr 2017Wali is a backdoor used for targeted attacks. It gathers information about the compromised machines and their networks, in addition to stealing sensitive information and credentials. Wali’s operators use this information to move laterally in an organization and compromise more machines.
Nov 2017Daserf’s infection chain accordingly evolved, as shown below. It has several methods for infecting its targets of interest: spear phishing emails, watering hole attacks, and exploiting a remote code execution vulnerability (CVE-2016-7836, patched last March 2017) in SKYSEA Client View, an IT asset management software widely used in Japan.
