Development of the Ukrainian Cyber Counter-Offensive


Russia’s military incursion against Ukraine began on February 24, 2022, with a massive ground attack supported by several cyber incidents. This activity set the stage for what would become an active hybrid war fought in two domains: cyber and ground warfare.

On Ukraine’s side, a loose cyber collective developed into the IT Army of Ukraine, launching DDoS attacks targeting Russian infrastructure, including airports, public transportation, government facilities, financial institutions, and private organizations. Cyber operations also targeted Moscow’s Stock Exchange website and the Russian Federal Tax Service. Even as recently as this week, the IT Army claimed to have breached the Central Bank of Russia, stealing thousands of internal documents and dumping 2.6 GB of data publicly.

In this post, we will cover the IT Army of Ukraine from its start at the very beginning of the war as a loose collective of cybersecurity experts and hackers, to a well-organized nation-state group of defensive and offensive actors with specific roles and purposes.

From Cyber Collective to IT Army

On February 24, 2022, Yegor Aushev, co-founder of a cybersecurity company located in Kyiv, posted a call to cyber arms on several hacker forums, enlisting the aid of those with a cybersecurity background and hacking skills. Volunteers and various hacktivists joined together to form Ukraine’s cyber counter offense collective which developed into a more formalized group referred to as the ‘IT Army of Ukraine.’

The term ‘IT army’ was first introduced by Mykhailo Fedorov, a Minister of Digital Transformation of Ukraine, in a social media post on February 26, 2022 consequently beginning the IT Army’s operations.

In another call to arms, Yegor Aushev, co-founder of a cybersecurity company in Kyiv, posted "Ukrainian cybercommunity! It's time to get involved in the cyber defense of our country." In an interview with Reuters Aushev stated that he “wrote the post at the request of a senior defense ministry official who contacted him" that day.

Targeting Russia

Based on Aushev’s statements, the collective is believed to be composed of two groups: an open collective of hacktivists whose task is to target and launch DDoS attacks against Russian infrastructure, and an in-house team of cyber operatives who are tasked with launching more complex operations, such as those highlighted in Stefan Soesanto’s CSS Cyberdefense Report.

IT Army of Ukraine Cyber Operations

After being formed, Ukraine’s IT Army almost immediately launched its first attack against Russian corporate and state entities. Information about this cyber operation, along with a call to use DDoS and other attack types against 31 Russian targets, was shared on a Telegram channel titled ‘itarmyofukraine2022.’

On February 28, 2022, the IT Army breached Moscow’s Stock Exchange website rendering it inaccessible just five minutes after the attack was launched, according to a Telegram post. The IT Army claims to have taken down Sberbank’s website. Sberbank is the largest bank in Russia. The attack resulted in an interruption of the payment system services, a small loss of funds, but had no major impact.  

Also on February 28, the Russian media agency Interfax published a quote from Roskomnadzor stating, "A hybrid war is currently being waged against Russia that includes elements of disinformation, as well as traditional cyberwarfare." Roskomnadzor is the Russian Federal Service for Supervision of Communications, Information Technology and Mass Media, a federal executive body responsible for overseeing the media, including electronic media, mass communications, information technology, and telecommunications.

As the IT Army grew in number, it attracted members with diverse skillsets, adding to the group’s targeting capabilities.

The growth in size and mission scope created a need to support the IT Army’s members by furnishing them with scripts to run, and highlighted an opportunity to develop and introduce educational materials and hacking guidelines, which could be accessed and shared via an educational portal:

The IT Army of Ukraine also provides its members with English language learning resources to better aid them in learning and acquiring cybersecurity skills and knowledge.

As information about the IT Army’s mission was shared, support from organizations such as the Student Committee of Cybersecurity and the Defense of Ukraine joined the cause. The group stated that it was beginning to attack Russian resources with the target being Mosmetro, also known as the Moscow Metro. Mosmetro is a metro system serving Moscow and neighboring cities.

The group also shares news about the Russian Federation as reported in the media and government sources.

The IT Army’s operational methods have matured since the group’s inception, including using Telegram as the central communication point for the hundreds of thousands of hacktivists located around the world. In addition to tasking the IT Army with launching DDoS attacks against specified Russian targets, other attack types encouraged on Telegram’s ‘itarmyofukraine2022’ channel include reporting Russian YouTube propaganda channels, and signing petitions to block PayPal, GitHub, and similar services in Russia. New targets and operational methods continue to be posted in the ‘itarmyofukraine2022’ channel.

Not long after creating the Telegram channel, the first automated scripts and guides, which included instructions on constructing VPNs, started to appear.

The first scripts facilitated DDoS attacks, targeting the Mir payment system in Russia, following a suspension of services in Russia from Mastercard, Visa, and American Express.

Automated tools, such as Death by 1000 needles, Liberator, and mhddos_proxy were created by the IT Army specifically for its members, which allowed them to automatically retrieve target lists and perform DDoS attacks with minimal effort.

On April 1, 2022, the IT Army launched an automated chatbot on Telegram that responds to questions and provides an instruction guide detailing how to execute DDoS attacks. Not long after the chatbot became active, the IT Army of Ukraine created a website sharing its target list, and details on how to launch a DDoS attack.

In May, an attack automation function was introduced to the Telegram chatbot which allowed volunteers to grant bot access to their cloud resources. This action could allow a coordinated attack from all available servers, maximizing the scale of a DDoS attack. To prevent proactive fixes on the attacked resources, the IT Army closed sourced its mhddos_proxy tool to gain better operational security against abuse from hostile threat actors. The cyber collective also stopped publicly sharing their target list.

According to the information provided on the IT Army of Ukraine’s official website, the group has now become a well-organized operation with a coordinated team that includes experts from the following fields:

  • Cyber ​​security experts who identify a potential target’s vulnerabilities
  • Economists who identify targets that will significantly impact the enemy's economy
  • Attack solution developers who update the software, allowing for more effective strikes
  • Moderators who assist the IT Army by reading messages and passing important information to other members of the cyber collective for analysis and involvement in future campaigns

On October 7, 2022, the IT Army of Ukraine’s members defaced the ODKB’s (Collective Security Treaty Organization) official websites. The URL in the screenshot below leads to the Internet archive service Wayback Machine:

The defacement text can be translated to: “IT-army of Ukraine is in touch. We would like to congratulate Putin on his last birthday and wish him a <comfortable> trip to The Hague!”

Since October 7, 2022, the IT Army of Ukraine has focused on Russian financial institutions and businesses such as Sberbank, Gazprombank, Credit Bank of Moscow, Wildberries, and others.

On October 20, the IT Army of Ukraine launched a DDoS against Russia’s Federal Tax Service blocking Russian taxpayers from submitting tax forms, retrieving documents, and caused an interruption in communications with the Federal service.

On October 22, the IT Army of Ukraine launched another attack against the Russian Federal Tax Service.

In a surprising show of anti-war, anti-Russian sentiment, the NRA claims to have breached Technoserv – Russia’s largest systems integrator company. The NRA also claims to have uncovered a connection between Technoserv and Russia’s Federal Security Service.


While we've seen a great deal of coordinated nation-state and Russian-sympathetic attackers in this conflict from the Russian side, the "crowd-sourced" methodology of the IT Army of Ukraine is a somewhat unique technique. Its ability to coordinate resources on a massive scale is something that probably hasn't been seen since the early days of Anonymous vs. Scientology.
