A professional hacking team affiliated with the North Korean government infiltrated the German company Diehl Defence, known for producing air defense systems and missiles, using phishing tactics to target employees. The group, attributed to the Kimsuky APT, employed booby-trapped files and mock job offers to carry out the attack. Kimsuky is known for intelligence gathering in support of North Korea’s nuclear and strategic efforts.
From the meeting notes, it is evident that a professional hacking team linked to the North Korean government, known as Kimsuky APT, has successfully broken into the German company Diehl Defence. This breach employed a phishing campaign and social engineering tactics, using booby-trapped PDF files and spear-phishing lures offering fake job opportunities to the company’s employees. This is a significant breach, considering Diehl Defence’s specialization in missile and ammunition production and its recent deal with South Korea.
Mandiant researchers investigated the compromise and observed that the attackers conducted detailed reconnaissance on Diehl Defence before launching the spear-phishing attacks. The attackers cleverly hid their attack server behind an address referencing Diehl Defence’s location in Southern Germany and hosted authentic-looking, German-language login pages resembling those of telecommunications provider Telekom and email service GMX to harvest login credentials.
Kimsuky, also known as APT43, Velvet Chollima, Emerald Sleet, TA406, and Black Banshee, is focused on intelligence gathering to support Pyongyang’s nuclear and strategic efforts. This threat group has targeted various entities, including governments, think tanks, research centers, universities, and news organizations in the United States, Europe, and Asia. The US government has imposed sanctions on individuals associated with Kimsuky and issued advisories regarding the group’s hacking activities.
It is crucial to note that this breach has significant implications, and swift action should be taken to mitigate the compromised security. The severity of the attack underscores the importance of cybersecurity measures for all organizations, particularly those involved in defense-related activities. It is recommended to stay updated on any further developments in this matter and take proactive steps to strengthen cybersecurity defenses.
