Verdict: Malicious activity
Threats:

BlackMoon also known as KrBanker is a trojan aimed at stealing payment credentials. It specializes in man-in-the-browser (MitB) attacks, web injection, and credential theft to compromise users' online banking accounts. It was first noticed in early 2014 attacking banks in South Korea and has impressively evolved since by adding a number of new infiltration techniques and information stealing methods.
