Similarity hashes should be used for research and clustering only. They do not prove that two files are identical or from the same campaign.
A valid digital signature identifies a publisher and file integrity state, but it does not by itself guarantee that a file is safe.

Frequently Asked Questions
Is Kimsuky dangerous?
It can be dangerous depending on the variant, payload, and system exposure. Treat it as a serious threat if detected.
Can Kimsuky steal passwords?
Some malware families in this category may attempt to access browser data, saved credentials, cookies, tokens, and sensitive files.
Does every sample behave the same way?
No. Malware families often contain multiple variants, so capabilities and impact can differ between individual samples.
Can this page confirm that my device is infected?
No. This page is educational research. A trusted security scan and qualified technical assessment are needed to evaluate a specific device.
