Analysis Summary
KONNI is a remote access tool that North Korean cyber attackers have been using since at least 2014. The North Korean hacker group distributes Konni RAT via phishing messages or emails. The infection chain begins when the victim accesses a weaponized file. Adversaries employ Konni RAT to gather information from victims, capture screenshots, steal files, and build a remote interactive shell. KONNI has been linked to various alleged North Korean attacks targeting political groups in Russia, East Asia, Europe, and the Middle East. KONNI shares a significant code overlap with the NOKKI malware family. Konni’s APT Group continues to attack malicious documents written in Russian. This threat actor group conducts attacks with Russian-North Korean trade and economic investment documents.
This APT group was detected targeting the Russian diplomatic sector in January 2022, employing a spear phishing theme for New Year’s Eve festivities as a bait. When the malicious email attachment is opened and processed, a series of events occur, allowing the actor to install an implant from the Konni RAT family as the final payload.
