A spear phishing campaign targeting a Colombian government agency under the Ministry of Commerce, Industry and Tourism was discovered in September 2025. The attack, attributed to BlindEagle, utilized a compromised email account within the organization to bypass security controls. The campaign employed a sophisticated multi-layer attack chain, including a fake web portal, nested JavaScript and PowerShell scripts, steganography, and the deployment of Caminho as a downloader for DCRAT. The attack leveraged legal-themed lures, in-memory execution, and abuse of legitimate services like Discord. BlindEagle's evolution in tactics and use of new tools like Caminho demonstrates their ongoing threat to Colombian institutions.
A malware campaign in Latin America uses oversized SVG files containing the full malicious payload to deliver AsyncRAT, a remote access trojan. The attack employs social engineering via emails impersonating trusted institutions with urgent legal warnings, primarily targeting Colombia. Clicking the SVG file opens a fake judicial portal to deceive victims. The campaign uses DLL sideloading to evade detection and AI-generated templates for customization. This method avoids external connections by embedding the payload directly in the SVG file. Attacks peaked mid-week in August, focusing on judicial system impersonation. No CVSS score is available, but the threat is medium severity due to its stealth and control capabilities. European organizations should be aware of this evolving tactic as it could be adapted to target other regions. Vigilance against suspicious SVG attachments and advanced detection techniques are critical for defense.
Between August and October 2025, a phishing campaign targeted Colombian users by impersonating the Attorney General's office to deliver the PureHVNC Remote Access Trojan (RAT) via the Hijackloader malware loader. The attack chain involved sophisticated techniques such as DLL side-loading, anti-virtual machine checks, and multiple code injection methods to evade detection and maintain persistence. This campaign marks the first known use of Hijackloader to deliver PureHVNC in Spanish-speaking Latin America, signaling an evolution in regional threat actor tactics. Although primarily focused on Colombia, the use of phishing and advanced evasion techniques poses a risk to organizations with similar user profiles or language contexts. The campaign's medium severity reflects the complexity and potential for unauthorized remote access but lacks evidence of widespread exploitation beyond the initial targets. Defenders should prioritize user awareness, advanced endpoint detection, and monitoring for indicators of DLL side-loading and unusual process injections. No CVSS score is available; based on impact and exploitation complexity, the threat is assessed as medium severity.
