Rewterz Threat Alert – Kimsuky APT Group – Active IOCs

Severity

High

Analysis Summary

The North Korean advanced persistent threat (APT) group Kimsuky has been found to be distributing a fake Korean Internet and Security Agency (KISA) app via malicious emails. A mobile malware researcher has shared information about a fake KISA vaccine or security android app disguised as the KISA security program. 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.
