APT 'Blind Eagle' Cyberattacks Target Colombian Government Institutions

In a concerning development, the South American-based Advanced Persistent Threat (APT) group known as “Blind Eagle” (also tracked as APT-C-36) has intensified its cyberattacks on Colombian government institutions. The attacks, which began in November 2024, have targeted various Colombian entities, including judicial bodies and government organizations. With a high infection rate, these operations have raised alarms about the threat actor’s growing capability and intent. This article delves into the specifics of the attacks, the tactics employed, and the broader implications for cybersecurity in Colombia.

APT Blind Eagle Campaigns Against Colombian Targets

In a recent report published on March 10, 2025, Check Point Research revealed that “Blind Eagle” has been leveraging a vulnerability associated with CVE-2024-43451 to execute its cyberattacks. The vulnerability, related to the Windows NTLMv2 hash, was initially patched by Microsoft in November 2024. However, the threat actor has developed a variant of this exploit, allowing them to continue targeting victims even after the patch was released.

One of the most alarming aspects of this attack campaign is its efficiency. Check Point’s research indicates that more than 1,600 victims were affected during one particular attack campaign on December 19, 2024. This high infection rate is unusual for a targeted APT group like Blind Eagle, which is typically associated with espionage and cybercrime aimed at specific government or infrastructure targets.

Blind Eagle has been active since 2018 and has primarily focused on government institutions, critical infrastructure, and financial organizations across Colombia and other Latin American nations. The group is known for its sophisticated social engineering tactics, including phishing emails with malicious attachments or links that facilitate the deployment of remote access trojans (RATs) like NjRAT, AsyncRAT, and Remcos.

The infection chain typically begins with a phishing email containing a malicious .url file, often disguised as an invoice or payment receipt. When downloaded, this file triggers a series of malicious actions, ultimately leading to the installation of the Remcos RAT and other malware payloads. These infections often involve command-and-control servers and botnets that further compromise the targeted systems.

What Undercode Says: Analyzing the Threat Landscape

Blind Eagle’s tactics reflect the growing sophistication of APT groups targeting government institutions and private organizations, particularly in Latin America. These attacks highlight the vulnerabilities in systems that, despite being patched, remain susceptible to variants of known exploits. While patching is an essential defense, it’s evident that cybercriminals like Blind Eagle are constantly evolving, ensuring that their attacks can bypass traditional security measures.

One key aspect of Blind Eagle’s success is its use of legitimate cloud platforms like Google Drive, Dropbox, and GitHub to distribute malware. These services are commonly trusted by both users and organizations, allowing attackers to bypass traditional security measures. For example, in the case of the phishing campaign detailed by Check Point, the malicious .url file was hosted on a potentially compromised Google Drive account. By using legitimate file-sharing platforms, Blind Eagle can stealthily distribute malware, making it harder for security systems to detect and block the threat.

Furthermore, Blind Eagle’s ability to exploit human error through social engineering techniques remains a significant vulnerability. Phishing remains one of the most effective methods for cybercriminals to gain initial access to target systems. The use of deceptive emails that appear legitimate—such as payment receipts—demonstrates how easily users can be manipulated into downloading malicious files.

This combination of advanced malware, social engineering, and the exploitation of trusted platforms makes Blind Eagle a formidable threat. Organizations must go beyond traditional antivirus and patching systems and focus on proactive threat intelligence and continuous monitoring to detect such campaigns early.

Another critical aspect of this attack is the high infection rate, which is unusual for a group focused on espionage. It suggests that Blind Eagle may be shifting tactics, perhaps aiming for more widespread disruption rather than the more targeted, stealthy campaigns typical of APT groups. This shift could signal a broader strategic goal or a change in resources that enables the group to scale its operations.

The focus on Colombia, in particular, reflects the geopolitical context in which these cyberattacks are occurring. As one of South America’s largest economies, Colombia is a prime target for cyber espionage and political destabilization efforts. The country’s judicial institutions and critical infrastructure are likely seen as valuable targets for both intelligence gathering and disruption. In this context, the increasing frequency and scale of these attacks suggest that Blind Eagle may be emboldened by its successes, intensifying its focus on both Colombian and broader Latin American targets.

Fact Checker Results

CVE-2024-43451 Vulnerability: Correct, this vulnerability was patched in November 2024 by Microsoft.
Targeted Entities: Accurate, the attacks have predominantly targeted Colombian government institutions and critical infrastructure.
Infection Rate: Verified, Check Point’s report confirms over 1,600 victims were affected in one attack.

In conclusion, the rise of Blind Eagle’s cyberattacks against Colombia emphasizes the urgent need for stronger cybersecurity defenses, particularly in government and critical sectors. The group’s use of innovative tactics and legitimate cloud services makes traditional security measures less effective, suggesting a need for more comprehensive, adaptive security strategies.
