SOCRadar Training Series – Mastering AI in Cybersecurity From Theory to Practice
Resources
In the ever-evolving landscape of cybersecurity threats, new groups like Hunt3r Kill3rs emerge with claims of disruptive capabilities. This analysis aims to provide an initial understanding of their activities, considering the limited timeframe and absence of concrete evidence substantiating their claims.

Hunt3r Kill3rs’ logo
Hunt3r Kill3rs, a recently surfaced threat group, assert their prowess in cyber operations, including Industrial Control Systems (ICS) breaches, communication network intrusions, and web application vulnerabilities exploitation. Despite their claims, the verifiable impact and sophistication of their operations remain unclear.
The group frequently claims to attack Operational Technology (OT) systems, including recent assertions of compromising companies using Unitronics PLCs. Unitronics PLC devices have been a common target for Iranian threat actors, particularly during the Israel-Hamas conflict. In response even CISA has issued advisories to enhance the security of these devices.
In a notable announcement, Hunt3r Kill3rs claimed to be launching a joint attack with Народная Кибер Армия (Cyber Army of Russia). Their stated targets include the US nuclear and electric power industries, specifically mentioning the Nuclear Energy Institute and the Electric Power Research Institute. They allege these resources have been disabled, though independent verification is lacking.

Collaboration announcement
It is observed that Iranian groups often collaborate with Russian threat actors or at least target similar objectives. In this context, it is plausible that information exchange occurs within this pro-Russian hacktivist sphere.
This hypothesis is supported by the group’s claimed association with Cyber Army of Russia. Cyber Army of Russia’s extensive network, encompassing pro-Russian or in some context anti-Israel hacktivist collectives like High Society from various countries including Yemen to India, likely facilitates the sharing of information and tactics.
Some of the techniques and claims that we consider important are as follows:
Industrial Control Systems (ICS) Allegations
Hunt3r Kill3rs boast about infiltrating ICS, targeting prominent brands like Siemens and Unitronics. However, without corroborated evidence, the extent of their success in disrupting critical infrastructure remains speculative. Thus, they share screenshots.

Latest Telegram post, an alleged claim of Unitronics PLC infiltration
Communication Network Intrusions:
The group alleges breaches in communication networks, particularly targeting IP phone systems from vendors such as Cisco. Verification of these intrusions and their implications on communication services is pending.

Claims about Cisco IP Phone systems
Web Application Vulnerabilities Exploitation
Hunt3r Kill3rs claim to exploit vulnerabilities in web applications, citing instances like SQL injection attacks on platforms such as WordPress-based e-commerce sites. The actual impact on targeted websites and data integrity requires thorough investigation. If the claim is true, attacks made by such groups often only result in the website being defaced.
Industries Supposedly Impacted
Considering the claims they shared on their Telegram channels, we arrive at the following data.
Claims of disruptions in manufacturing, suggested breaches in transportation systems. Lastly, joint attacks with Народная Кибер Армия have allegedly targeted the US nuclear and electric power sectors, specifically the Nuclear Energy Institute and the Electric Power Research Institute.
Israel: The group’s claims of targeting Israeli cybersecurity centers and critical infrastructure, the first post on their Telegram channel is also about Israel.

One of the first posts in their Telegram channel
Germany: Alleged surveillance network breaches and infrastructure disruptions. Their latest alleged attack on Germany targeted a company called Mobotix. The claim suggested that the threat actors have fully penetrated the infrastructure and gained live access to cameras around the world.
Ukraine: Claims of strategic cyber actions in Ukraine highlight geopolitical motivations, yet evidence is inconclusive.
United States: The claimed joint attack with Народная Кибер Армия on US nuclear and electric power sectors and targeting companies with Unitronics products were a few examples of their targeting of the US.
Hunt3r Kill3rs’ emergence underscores the ongoing challenges in discerning genuine threats from exaggerated claims in the cybersecurity domain. As a relatively new group with unverified assertions, their activities warrant cautious monitoring and thorough investigation by cybersecurity experts and relevant authorities.
Given the speculative nature of Hunt3r Kill3rs’ claims, organizations should:
Finally, it should not be forgotten that operations operating under the name of “hacktivism” can be a screen for more dangerous cyber operations, or individual small actions of these groups can cause devastating consequences when they act together.
Therefore, this analysis serves as an initial assessment and encourages a balanced approach in evaluating emerging cybersecurity threats like Hunt3r Kill3rs.
