Cyber warfare is increasingly being conducted outside of centralized military or government efforts. In Ukraine, without direct government supervision, thousands of private individuals and organizations are involving themselves in the cyber-war against Russia. Yurii Shchyhol is head of Ukraine’s State Service of Special Communications and Information Protection. Speaking to Politico, he commends a group of “more than 270,000 volunteers who are self-coordinating their efforts and who can decide, plan, and execute any strikes on the Russian cyber infrastructure without Ukraine getting involved in any shape or form.”

‘Hacktivists’ have existed since the 1990s, but the term seems ill-suited to the scale and approach Shchyhol is describing. They might instead be labelled an auxiliary cyber force, playing a supportive role in a larger military effort. Shchyhol himself calls them “an army”. 

Open-source warfare

In the modern cyber landscape, anyone with a computer and a basic skill set can contribute to a war. Depending on who and perhaps where you are, this fact is inspiring, concerning, or a little of both. The challenge of distinguishing between official nation-state attacks and hacktivists raises certain issues, making it possible, for instance, for nation-states to conduct devastating attacks against critical national infrastructure from behind a mask of proxy criminal organizations. The ties between nation states and these organizations may be suspected, but any accusations are rarely confirmed. 

The converse problem is seen when idealistic individual actors launch provocative attacks with the potential to stoke tensions between nation states. Recent DDoS and defacement attacks against Taiwanese government sites and businesses are largely being attributed to Chinese hacktivists, but with the perpetrators unidentified, these attacks remain a concerning question mark and do little to ameliorate sharply rising tensions. A spokesperson for Taiwan’s ruling party has already said in a statement that these attacks are “unilaterally raising the situation in the Taiwan Strait.” Official Taiwanese websites, like that of the Presidential Office, the Ministry of National Defense, and a municipal Environment Protection Bureau have all been targeted, the latter defaced with five Chinese national flags. 

A spate of similar defacements preceded Russia’s February invasion of Ukraine, with more than a dozen Ukrainian national websites made to display threats like, “be afraid and expect the worst”. Once again, the perpetrators of this attack remained unconfirmed, with Ukrainian government institutions accusing the Russian Federation, and Russia denying all involvement. The degree to which modern war efforts can be influenced by – or concealed behind – individual threat actors is a new and disconcerting symptom of the modern cyber landscape. There are, however, more official ways in which cyber warfare has moved beyond government and military organizations as well.

Calling in a private cavalry

Just 15 months after it was opened by President Volodymyr Zelensky, the UA30 Cyber Center in Ukraine lies largely empty. It is located in an unsafe part of the war-torn country, and its operations have had to be moved elsewhere. In the time between its opening and Russia’s invasion in February, however, the center was able to host more than 100 cyber security training sessions. These sessions, which involved realistic cyber-attack simulations, hackathons, and other competitions, were attended by some military operators, but also by large numbers of civilian contractors and private sector representatives. Their attendance was part of an intentional and significant effort to involve the private sector in Ukraine’s cyber defense efforts. 

Shchyhol explains, “a lot of private sector IT cyber security experts are either directly serving in the Armed Forces of Ukraine or my State Service or otherwise are indirectly involved in fighting against cyber-attacks.” This is the realization of the UA30 Cyber Center’s aim: using crucial assistance and expertise from the private sector in national cyber-defense efforts, and bolstering the security of those organizations on which Ukraine’s critical national infrastructure depends. As we have seen with attacks against Ukrainian telecom and internet providers, organizations operating the infrastructure which underpins a population’s daily life are often the first – and most appealing – targets for attackers looking to create disorder within a nation. 

It is not only Ukraine’s own private sector which is lending a hand. International organizations like SpaceX and Amazon have contributed to Ukraine’s efforts by providing technology and infrastructure, as well as their own expertise and services. In its report on Early Lessons from the Cyber War, Microsoft suggests that “defense against a military invasion now requires for most countries the ability to disperse and distribute digital operations and data assets across borders and into other countries”. With cloud services provided by Amazon, Microsoft and others, and data now hosted across Europe, Ukraine is managing to do just that. Like its army of guerilla cyber-fighters, the involvement of private organizations is dispersing and bolstering Ukraine’s war effort.

The new home front

Beyond these direct contributions, however, Shchyhol also notes those private sector organizations supporting the cyber-war “indirectly”. These indirect efforts have been a focus of US government statements on cyber security since the beginning of the conflict. A statement from President Biden in March read, “I urge our private sector partners to harden your cyber defenses immediately”, a message which has been repeated and reinforced by CISA.  

The great responsibility which private organizations have for critical national infrastructure has been highlighted in attacks like that on Colonial Pipeline last year, but organizations in every industry can offer opportunities for nation-state attackers. When more organizations are sufficiently prepared for cyber-attacks, the nation as a whole becomes stronger. 

In its report, Microsoft calls for “a common strategy” to thwart modern cyber-threats, which includes the need for greater public and private collaboration and advances in digital technology, Artificial Intelligence (AI), and data. By adopting stronger defenses, and employing well-suited emerging AI technologies, organizations can accelerate the detection and prevention of threats, and contribute to national security in the face of constantly developing international cyber-threats. 

When cyber-attackers are provided with funding, coordination, and thorough threat security intelligence, they can create scores of never-before-seen attacks, which circumvent pre-established security rules and avoid detection. As attackers develop their approach, so must defenders - not just by employing the latest technologies, but by embracing the changes in defensive strategy which those technologies enable. Defenders need to pivot away from focusing on patterns and predictions, and concentrate on understanding the landscapes and ‘normal’ operations of their digital environments. With this approach they can harden attack paths, visualize their internet-facing attack surface, detect the smallest deviations from ‘normal’, and disrupt attackers before damage is done.  

For private sector organizations, auxiliary cyber forces, and hacktivists alike, focusing on defensive rather than offensive action will be the surest way to win the battle and the war.

Patch and Persist: Darktrace’s Detection of Blind Eagle (APT-C-36)

login on laptop dual factor authenticationDefault blog imageDefault blog image

What is Blind Eagle?

Since 2018, APT-C-36, also known as Blind Eagle, has been observed performing cyber-attacks targeting various sectors across multiple countries in Latin America, with a particular focus on Colombian organizations.

Blind Eagle characteristically targets government institutions, financial organizations, and critical infrastructure [1][2].

Attacks carried out by Blind Eagle actors typically start with a phishing email and the group have been observed utilizing various Remote Access Trojans (RAT) variants, which often have in-built methods for hiding command-and-control (C2) traffic from detection [3].

What we know about Blind Eagle from a recent campaign

Since November 2024, Blind Eagle actors have been conducting an ongoing campaign targeting Colombian organizations [1].

In this campaign, threat actors have been observed using phishing emails to deliver malicious URL links to targeted recipients, similar to the way threat actors have previously been observed exploiting CVE-2024-43451, a vulnerability in Microsoft Windows that allows the disclosure of a user’s NTLMv2 password hash upon minimal interaction with a malicious file [4].

Despite Microsoft patching this vulnerability in November 2024 [1][4], Blind Eagle actors have continued to exploit the minimal interaction mechanism, though no longer with the intent of harvesting NTLMv2 password hashes. Instead, phishing emails are sent to targets containing a malicious URL which, when clicked, initiates the download of a malicious file. This file is then triggered by minimal user interaction.

Clicking on the file triggers a WebDAV request, with a connection being made over HTTP port 80 using the user agent ‘Microsoft-WebDAV-MiniRedir/10.0.19044’. WebDAV is a transmission protocol which allows files or complete directories to be made available through the internet, and to be transmitted to devices [5]. The next stage payload is then downloaded via another WebDAV request and malware is executed on the target device.

Attackers are notified when a recipient downloads the malicious files they send, providing an insight into potential targets [1].

Darktrace’s coverage of Blind Eagle

In late February 2025, Darktrace observed activity assessed with medium confidence to be  associated with Blind Eagle on the network of a customer in Colombia.

Within a period of just five hours, Darktrace / NETWORK detected a device being redirected through a rare external location, downloading multiple executable files, and ultimately exfiltrating data from the customer’s environment.

Since the customer did not have Darktrace’s Autonomous Response capability enabled on their network, no actions were taken to contain the compromise, allowing it to escalate until the customer’s security team responded to the alerts provided by Darktrace.

Darktrace observed a device on the customer’s network being directed over HTTP to a rare external IP, namely 62[.]60[.]226[.]112, which had never previously been seen in this customer’s environment and was geolocated in Germany. Multiple open-source intelligence (OSINT) providers have since linked this endpoint with phishing and malware campaigns [9].

The device then proceeded to download the executable file hxxp://62[.]60[.]226[.]112/file/3601_2042.exe.

Darktrace’s detection of the affected device connecting to an unusual location based in Germany.

Figure 2: Darktrace’s detection of the affected device downloading an executable file from the suspicious endpoint.

The device was then observed making unusual connections to the rare endpoint 21ene.ip-ddns[.]com and performing unusual external data activity.

This dynamic DNS endpoint allows a device to access an endpoint using a domain name in place of a changing IP address. Dynamic DNS services ensure the DNS record of a domain name is automatically updated when the IP address changes. As such, malicious actors can use these services and endpoints to dynamically establish connections to C2 infrastructure [6].

Further investigation into this dynamic endpoint using OSINT revealed multiple associations with previous likely Blind Eagle compromises, as well as Remcos malware, a RAT commonly deployed via phishing campaigns [7][8][10].

Darktrace’s detection of the affected device connecting to the suspicious dynamic DNS endpoint, 21ene.ip-ddns[.]com.
Figure 3: Darktrace’s detection of the affected device connecting to the suspicious dynamic DNS endpoint, 21ene.ip-ddns[.]com.

Shortly after this, Darktrace observed the user agent ‘Microsoft-WebDAV-MiniRedir/10.0.19045’, indicating usage of the aforementioned transmission protocol WebDAV. The device was subsequently observed connected to an endpoint associated with Github and downloading data, suggesting that the device was retrieving a malicious tool or payload. The device then began to communicate to the malicious endpoint diciembrenotasenclub[.]longmusic[.]com over the new TCP port 1512 [11].

Around this time, the device was also observed uploading data to the endpoints 21ene.ip-ddns[.]com and diciembrenotasenclub[.]longmusic[.]com, with transfers of 60 MiB and 5.6 MiB observed respectively.

Figure 4: UI graph showing external data transfer activity.

This chain of activity triggered an Enhanced Monitoring model alert in Darktrace / NETWORK. These high-priority model alerts are designed to trigger in response to higher fidelity indicators of compromise (IoCs), suggesting that a device is performing activity consistent with a compromise.

A second Enhanced Monitoring model was also triggered by this device following the download of the aforementioned executable file (hxxp://62[.]60[.]226[.]112/file/3601_2042.exe) and the observed increase in C2 activity.

Following this activity, Darktrace continued to observe the device beaconing to the 21ene.ip-ddns[.]com endpoint.

Darktrace’s Cyber AI Analyst was able to correlate each of the individual detections involved in this compromise, identifying them as part of a broader incident that encompassed C2 connectivity, suspicious downloads, and external data transfers.

Figure 7: Cyber AI Analyst’s detection of the affected device’s broader connectivity throughout the course of the attack.

As the affected customer did not have Darktrace’s Autonomous Response configured at the time, the attack was able to progress unabated. Had Darktrace been properly enabled, it would have been able to take a number of actions to halt the escalation of the attack.

For example, the unusual beaconing connections and the download of an unexpected file from an uncommon location would have been shut down by blocking the device from making external connections to the relevant destinations.

Conclusion

The persistence of Blind Eagle and ability to adapt its tactics, even after patches were released, and the speed at which the group were able to continue using pre-established TTPs highlights that timely vulnerability management and patch application, while essential, is not a standalone defense.

Organizations must adopt security solutions that use anomaly-based detection to identify emerging and adapting threats by recognizing deviations in user or device behavior that may indicate malicious activity. Complementing this with an autonomous decision maker that can identify, connect, and contain compromise-like activity is crucial for safeguarding organizational networks against constantly evolving and sophisticated threat actors.
