The Kimsuky group is a threat group that is known to have been behind the KHNP (Korea Hydro & Nuclear Power) cyber terrorism attacks in 2014 and is still active as of 2019.
Since 2018, we have been profiling and tracking spear-phishing emails and malicious code related to the Kimsuky group (like Sequel of Campaign DOKKAEBI).
The spear-phishing email used in the attack was designed with the purpose of stealing portal account information and attaching malicious code. The main targets of the attack are government and military officials or reporters.
While others might think of this as a simple account hijack, or stop at a single malware analysis, we have analysed the group's changing behaviour through ongoing tracing of the IoCs related to Kimsuky, including simple account hijacking.
In this talk, we present the results of an analysis not only of the malware used by the Kimsuky group but also of server-side samples (tools and templates that send out spear-phishing emails, like a phishing-rod) which we recently investigated.
We have confirmed that the C&C server used for the previous attack continues to be used for various purposes such as distribution of malicious code, logging of infection and sending of phishing mails. This talk will provide a background to the Kimsuky group's recent activity and give an insight for malware researchers.
