Russia-linked hackers have been implicated in an ongoing cyber espionage campaign involving Kazakhstan, employing HATVIBE malware that shares characteristics with APT28-related Zebrocy campaigns. This marks a significant development in Russia's efforts to expand its influence through surveillance capabilities.
The HATVIBE malware strain is believed to be part of an intrusion set known as UAC-0063, also referred to as Blue Athena or Fancy Bear. The attack sequence exhibits characteristics reminiscent of APT28-related Zebrocy campaigns, raising concerns about attribution with medium confidence. UAC-0063 is thought to be linked to various nation-state groups affiliated with Russia's GRU and has been observed targeting organizations in Central Asia, East Asia, and Europe. The attack sequence begins with spear-phishing lures based on legitimate Microsoft Office documents and uses a multi-stage infection chain dubbed Double-Tap. The use of HTA files embedding VBS backdoors nicknamed 'HATVIBE' is a unique aspect of the attack, demonstrating technical overlaps with APT28-related campaigns. The employment of spear-phishing weaponized documents indicates a focus on collecting strategic intelligence on diplomatic relations between Central Asia states. Russia's efforts to expand its influence through surveillance capabilities using SORM technology have significant implications for global security.
The threat landscape has been witness to a rise in sophisticated cyber attacks, as malicious actors from around the world continue to advance their tactics, techniques, and procedures (TTPs). Recently, a new campaign involving Russia-linked hackers has been uncovered, which aims at Kazakhstan and other countries in Central Asia. The malware strain used by these attackers is dubbed HATVIBE, which is believed to be part of an intrusion set known as UAC-0063, also referred to as Blue Athena or Fancy Bear.
In a detailed analysis conducted by French cybersecurity firm Sekoia, it has been discovered that the HATVIBE attack sequence exhibits several characteristics reminiscent of APT28-related Zebrocy campaigns. This association raises concerns about the attribution of this particular cyber espionage campaign to the Russian hacking group with medium confidence.
According to Recorded Future's Insikt Group, UAC-0063 is thought to be linked to various other nation-state groups that are affiliated with Russia's General Staff Main Intelligence Directorate (GRU). The fact that it shares overlap with APT28 implies a high level of sophistication and planning on the part of these adversaries. Furthermore, this malware strain has been observed targeting organizations in Central Asia, East Asia, and Europe, underscoring its potential as a tool for espionage.
The attack sequence employed by UAC-0063 begins with the use of spear-phishing lures that are based on legitimate Microsoft Office documents originating from the Ministry of Foreign Affairs of the Republic of Kazakhstan. These documents have been embedded with malicious macros that can bypass security solutions and activate a multi-stage infection chain dubbed Double-Tap.
Upon running, these documents create a second blank document in the "C:\Users\[USER]\AppData\Local\Temp\" location, which is automatically opened by an initial macro to drop and execute a malicious HTA (HTML Application) file embedding a VBS [Visual Basic Script] backdoor nicknamed 'HATVIBE'. The HTA file designed for HATVIBE runs for four minutes by launching mshta.exe.
As the next stage of this attack, the Python-based bot named CHERRYSPY is executed. This attack sequence demonstrates technical overlaps with APT28-related Zebrocy campaigns and allows Sekoia researchers to attribute the UAC-0063 cluster to the Russian hacking group with medium confidence.
One thing that makes the Double-Tap infection chain quite unique is the multiple tricks employed by it to evade security solutions, including storing real malicious macro code in settings.xml and using an anti-emulation trick to determine if execution time has not been altered. The latter tactic ensures that the macro is stopped if its running time exceeds a predetermined limit.
The employment of spear-phishing weaponized documents by UAC-0063 indicates a focus on collecting strategic intelligence on diplomatic relations between Central Asia states, especially those involving Kazakhstan's foreign relations by Russian intelligence. This is part of the broader context in which cyber espionage campaigns are often designed to gather sensitive information about specific countries' economic and political systems.
The recent revelation that several countries in Central Asia and Latin America have purchased the System for Operative Investigative Activities (SORM) wiretapping technology from at least eight Russian providers underscores Russia's efforts to expand its influence through surveillance capabilities. This development has significant implications for global security, as it enables Moscow to intercept communications without being detected by service providers.
It is worth noting that the former Soviet territories of Belarus, Kazakhstan, Kyrgyzstan, and Uzbekistan, along with Latin American nations such as Cuba and Nicaragua, have been assessed as having very likely acquired this technology. The misuse of surveillance capabilities, including repression of political opposition, journalists, and activists without effective or independent oversight, is a well-documented practice among these governments.
In conclusion, the HATVIBE malware campaign represents an escalation in Russia's cyber warfare expansion efforts, marking a significant development in its use of sophisticated tools for espionage. The implications of this campaign are multifaceted, as it raises concerns about the misuse of surveillance technology by nation-states and underscores the need for robust cybersecurity measures to counter these threats.
