Introduction
Cybersecurity threats continue to evolve, with nation-state actors increasingly targeting strategic regions around the world. While much of the focus has been on Russia’s cyberattacks against Ukraine, a lesser-known but equally significant threat group, TAG-110, has been actively pursuing espionage operations in Central Asia. This article delves into the recent phishing campaign launched by TAG-110 in Tajikistan, shedding light on its implications and broader geopolitical significance.

TAG-110, a Russian state-sponsored threat group, has been targeting institutions in Tajikistan as part of a broader strategy to influence the post-Soviet region. According to Recorded Future’s Insikt Group, TAG-110’s cyber espionage operations are aimed at government, academic, and research institutions. Their activities are suspected to overlap with the infamous Russian cyber group, APT28, also known as Fancy Bear.
In early 2023, TAG-110 launched a sophisticated phishing campaign involving government-themed documents as lures. These documents, which appeared to be legitimate, contained poisoned Word files designed to exploit macro vulnerabilities. These files were used to install malware such as CHERRYSPY, LOGPIE, and PyPlunderPlug. The attack path was notably different from previous campaigns, skipping the malware step in favor of a more subtle infiltration method.
Despite the focus on Ukraine, TAG-110’s operations demonstrate Russia’s ongoing cyber activity outside of its borders, particularly in countries like Tajikistan, where Russia seeks to maintain influence. The group’s espionage efforts are likely tied to Russia’s military strategy, potentially gaining insight into NATO and European plans while monitoring post-Soviet nations that Russia wants to keep within its sphere of influence.
What Undercode Says: Analyzing the TAG-110 Phishing Campaign
The latest phishing campaign by TAG-110 is a clear example of the evolving sophistication of Russian cyber operations. While previous attacks were centered on more disruptive strategies, this campaign shows a shift towards targeted, stealthier espionage efforts. The use of poisoned Word documents and malicious macros highlights Russia’s growing expertise in social engineering, leveraging local governmental themes to deceive targets into opening malicious files.
A key element of the campaign is the manipulation of trust. By embedding malicious code into documents that seem official and relevant to Tajikistan’s military and political interests, TAG-110 taps into the natural trust users place in government communications. This tactic not only boosts the chances of success but also makes it harder to detect.
Moreover, the overlap between TAG-110 and other Russian cyber groups like UAC-0063 and APT28 suggests a well-coordinated effort within Russia’s cyber units. These groups likely share tactics, techniques, and procedures (TTPs) to maximize their reach and efficiency, enabling Russia to monitor not only Ukraine but also the broader post-Soviet space.
Russia’s broader geopolitical goals are also clear. With Tajikistan strategically located, any intelligence gathered could be used to influence regional security dynamics, especially as Russia seeks to assert its dominance in the region. This is particularly significant considering Tajikistan’s proximity to Afghanistan and its role in Central Asian geopolitics.
The shift in tactics—from a reliance on HTA-based malware to the use of macros for persistence—also underscores a growing sophistication in Russian cyber operations. It shows that TAG-110 is evolving to avoid detection and refine its attack strategies. This highlights the increasing complexity of nation-state cyber warfare and the growing need for robust cybersecurity measures.
Fact Checker Results
Target Region: TAG-110’s focus on Tajikistan is consistent with Russia’s broader strategy to secure a post-Soviet sphere of influence, extending beyond Ukraine to include Central Asia.
Malware Used: The malware families CHERRYSPY, LOGPIE, and PyPlunderPlug have been consistently used by Russian cyber groups, confirming the attribution to Russian state-backed actors.
Phishing Tactics: The use of poisoned macro-enabled Word documents is a well-documented technique by Russian cyber operatives, enhancing the credibility of the campaign’s reported methodology.
Prediction
Looking ahead, it is likely that TAG-110 will continue to target Central Asian countries, particularly those with close ties to Russia. These nations, given their strategic importance, are prime targets for Russian cyber-espionage operations. The increasing sophistication of these attacks suggests that similar tactics will be refined and reused in future campaigns, possibly involving other methods of infiltration like zero-day exploits or supply chain attacks.
As geopolitical tensions rise, especially with NATO and European countries, the scope of Russian cyber operations may expand further, involving more aggressive and disruptive tactics. Additionally, the growing interconnection between various Russian cyber groups could result in more coordinated attacks, leading to a surge in cyber espionage activities aimed at influencing key political and military events in the region.
