Introduction
Cyber warfare has evolved into a powerful and devastating weapon in global conflicts, and Ukraine has increasingly become a primary target of these sophisticated attacks. Recently, a new malicious malware known as PathWiper was deployed against Ukrainian critical infrastructure, reportedly by a Russia-linked advanced persistent threat (APT) group. This wiper has raised alarm due to its destructive capabilities and its connection to previous Russian-backed cyberattacks. Cisco Talos researchers uncovered the use of legitimate administrative tools to deploy this wiper, revealing the level of sophistication and familiarity the attackers have with their targets. Let’s dive deeper into the PathWiper malware and its implications on Ukraineās cybersecurity landscape.

Cisco Talos, a prominent cybersecurity research group, uncovered a new Russia-linked wiper malware known as PathWiper. The threat actor targeted Ukraineās critical infrastructure using legitimate administrative tools, signaling that they had deep access to the targetās systems. PathWiper is a destructive malware designed to wipe out files and disrupt systems. It works by scanning and identifying all connected storage devices, including network drives, and then overwriting key disk structures with random data. The wiper specifically targets critical NTFS file structures, such as the Master Boot Record (MBR) and \$MFT.
The malware was deployed using commands executed from an administrative console. These commands were run as batch files, resembling Impacket syntax, though there was no definitive proof of Impacketās involvement. PathWiper is notable for its precision, employing programmatic methods to locate and corrupt storage devices with efficiency.
The attack appears to be part of a broader trend in Russia-linked APT activity, where similar wipers have been used in previous campaigns against Ukrainian entities. The researchers also highlight that such tools allow the attackers to remain undetected for extended periods, maintaining a strong foothold in the target systems.
What Undercode Say:
Undercode’s analysis focuses on the strategic implications of PathWiperās deployment, shedding light on how Russia-linked APT groups leverage advanced malware in cyber warfare. PathWiperās technique of using legitimate administrative tools to bypass traditional security mechanisms is particularly concerning. It indicates that the attackers have intimate knowledge of the targetās infrastructure, which can significantly enhance their ability to inflict long-term damage without raising immediate suspicion.
Unlike earlier wipers like HermeticWiper, which also targeted Ukrainian entities, PathWiper uses a more refined approach to destroying data. The malwareās ability to specifically target NTFS structures, which are essential for the operation of many systems, means it can leave a lasting impact on the functionality of compromised devices. This is a calculated move by the attackers, who appear to be focused on crippling Ukraineās vital infrastructure rather than simply causing short-term disruption.
By leveraging administrative tools that could otherwise be considered safe and legitimate, the threat actors can remain under the radar while deploying powerful malware. This makes detection and mitigation far more difficult for cybersecurity teams, who may not initially suspect the presence of malicious activity due to the familiar tools being used. The increasing sophistication of these cyberattacks signals a shift in the landscape of cyber warfare, where the lines between legitimate operations and malicious activities are increasingly blurred.
Moreover, the use of multiple wipers in past attacks shows a coordinated strategy aimed at undermining Ukraineās resilience. The attackersā understanding of the local environment, combined with their choice of tools and methods, reveals a high level of expertise and intent. This underscores the growing trend of nation-state-backed cyberattacks, where the objective is not only data destruction but also the creation of long-term operational disruption.
The inclusion of Indicators of Compromise (IOCs) by Cisco Talos is an essential resource for organizations to track and defend against similar threats. However, the evolving nature of these cyberattacks means that cybersecurity measures must also evolve constantly to stay one step ahead.
Fact Checker Results ā
- Russia-linked Attribution: The identification of the threat actor as a Russian-backed APT group is highly credible. Previous attacks against Ukraine, such as HermeticWiper and Industroyer2, also showed similar tactics and techniques.
PathWiper Mechanism: The described functionality of PathWiper, including its targeting of NTFS structures like MBR and \$MFT, is consistent with known wiper malware behaviors. This is a reliable indicator of its destructive capabilities.
Use of Legitimate Admin Tools: The use of administrative tools to deploy PathWiper aligns with typical tactics seen in advanced persistent threat operations, confirming that the attackers likely had high-level access.
Prediction š®
Looking ahead, the deployment of PathWiper may signal a continued escalation in cyber warfare tactics targeting Ukraineās critical infrastructure. Given the precision and sophistication of this wiper, similar cyberattacks are likely to evolve, potentially leading to new, more advanced wiper variants designed to evade detection further. These threats may also spread beyond Ukraine, with other countries potentially becoming targets of similar attacks in the geopolitical conflict.
As cyber warfare tactics become more refined, the distinction between cybercriminal activity and state-sponsored attacks will become increasingly difficult to identify. Future attacks could leverage even more sophisticated tools, such as AI-driven malware, that learn and adapt to their environment, making them harder to detect and mitigate. Governments and private organizations worldwide will need to enhance their cybersecurity posture to defend against this growing and evolving threat.
