Lazarus Group Targeting Defense Experts with Fake Interviews via Trojanized VNC Apps

The Lazarus Group, a notorious North Korea-linked hacking group AKA Hidden Cobra or TEMP.Hermit, has embarked on a cunning campaign known as “Operation Dream Job.” This nefarious operation utilizes trojanized versions of Virtual Network Computing (VNC) applications to lure unsuspecting victims from the defense industry and nuclear engineering sectors. This article explores the recent findings and tactics employed by the Lazarus Group as detailed in Kaspersky’s APT trends report for Q3 2023.

Operation Dream Job: Deceptive Techniques

In their latest campaign, the Lazarus Group is making use of deceptive methods to compromise high-value targets. Job seekers active on social media platforms are tricked into downloading malicious applications, lured by the promise of a job interview. To evade detection by behavior-based security solutions, the trojanized VNC applications operate discreetly, remaining dormant until the user selects a server from the drop-down menu within the client. Once activated by the victim, the counterfeit application is designed to fetch additional payloads, including a well-known Lazarus Group malware known as LPEClient, which comes equipped with the ability to profile compromised hosts.

Targeting the Defense Sector

The Lazarus Group’s latest campaign has its sights set on businesses directly involved in defense manufacturing, ranging from radar systems and unmanned aerial vehicles (UAVs) to military vehicles, ships, weaponry, and maritime companies. The modus operandi of Operation Dream Job revolves around reaching out to potential targets via suspicious accounts on platforms like LinkedIn, Telegram, and WhatsApp. The group poses as recruiters offering attractive job opportunities, luring individuals into unknowingly installing malware.

In a Recent Case: The Lazarus Group Strikes Again. ESET recently disclosed details of a Lazarus Group attack directed at an aerospace company based in Spain. The attackers masqueraded as recruiters for Meta on LinkedIn, ultimately delivering an implant known as LightlessCan. This incident serves as a glaring example of the Lazarus Group’s audacity and sophistication in executing their cyber-espionage activities.

The Lazarus Group and Its History

Now, let’s understand the history of the Lazarus Group. The Lazarus Group is just one among several offensive programs originating from North Korea They have been associated with cyber-espionage activities and financially motivated thefts over the years. Another significant hacking group, APT37 (also known as ScarCruft), operates under the Ministry of State Security. In contrast to other threat activity clusters, which include APT43, Lazarus Group, and its sub-groups Andariel and BlueNoroff, are affiliated with the Reconnaissance General Bureau, showcasing the diversity of North Korean threat activity.

According to Google-owned Mandiant, North Korean threat actors are continuously evolving, adapting their tactics and tools. They are now tailoring malware for different platforms, including Linux and macOS, which reflects their adaptability and increasing complexity. Additionally, they have demonstrated a growing interest in developing macOS malware for backdooring high-value targets within the cryptocurrency and blockchain industries.

One noticeable shift in recent times is the increasing infrastructure, tooling, and targeting overlaps between various North Korean hacking outfits. Groups like Andariel, APT38, Lazarus Group, and APT43 are causing challenges in attribution efforts. This points to a streamlining of adversarial activities and signifies the North Korean regime’s growing interest in the cryptocurrency and blockchain industries.
