Rewterz Threat Alert – Kimsuky – Active IOCs

Severity

High

Analysis Summary

Kimsuky is a North Korean threat actor that has been active since 2012, primarily focuses on government entities in South Korea, and conducts espionage campaigns against targets in the U.S. and Japan. The Kimsuky group can set up phishing infrastructure to effectively mimic well-known websites and trick victims to enter their credentials. “This is one of the main methods used by this actor to collect email addresses that later will be used to send spear-phishing emails.” Earleir this year, a mobile malware researcher has shared information about a fake KISA vaccine or a security android app disguised as the KISA security program deployed by Kimsuky group. When the target downloads the APK implanted file from the email and installs the application on his device, the malicious code does its job. It executes in the background without the target’s knowledge and collects sensitive information from his device.I
