LAC Cybercrime Trends 2025: Banking Trojans and Ransomware Shifts
- [01] Immediate impact: Financial institutions and critical infrastructure in Brazil, Mexico, and Colombia face increasing threats from sophisticated banking trojans and specialized ransomware.
- [02] Affected systems: Organizations relying on legacy authentication and unpatched public-facing assets are primarily targeted for initial access and credential harvesting.
- [03] Remediation: Defenders must implement phishing-resistant multi-factor authentication and enhance endpoint monitoring to identify localized financial malware before lateral movement occurs.
According to Recorded Future, the Latin American and Caribbean (LAC) cybercrime landscape in 2025 is defined by a sophisticated mix of localized financial malware and international Ransomware operations. The region has historically served as a fertile ground for banking trojans, but recent shifts indicate that local actors are increasingly collaborating with global syndicates, adopting more advanced TTP sets to target both regional and international victims.
Evolution of Regional Banking Trojans
Financial crime remains the dominant motive within the LAC underground. Sophisticated malware families such as Grandoreiro and Mekotio continue to dominate the threat landscape. These threats typically utilize Phishing as their primary infection vector, often masquerading as official government or judicial documents to trick users into executing malicious installers.
Mekotio Banking Trojan Technical Analysis
A detailed Mekotio banking trojan technical analysis reveals that the malware specializes in credential theft through overlay attacks. When a victim accesses a targeted banking portal, the malware intercepts the browser session and presents a fake window that mimics the legitimate site. This allows the attacker to harvest credentials and second-factor authentication codes in real-time. The infrastructure supporting these operations often utilizes local C2 servers to bypass geo-fencing restrictions implemented by regional financial institutions.
Security teams focusing on regional operations should prioritize understanding how to detect banking trojans in Brazil, where these campaigns are most frequent. Common IoC patterns include unusual registry modifications for persistence and the presence of localized DLL sideloading techniques used to evade traditional signature-based detection.
Essential Latin America Ransomware Mitigation Steps
The ransomware threat in LAC has matured, moving from opportunistic attacks to targeted campaigns against critical infrastructure and government entities. Groups like LockBit have maintained a presence in the region by recruiting local affiliates who understand the specific regulatory and technical environments of their targets. These affiliates facilitate Lateral Movement within compromised networks, often utilizing living-off-the-land techniques to avoid triggering an EDR alert.
To defend against these threats, organizations should implement the following Latin America ransomware mitigation steps:
- Network Segmentation: Isolate critical financial and operational technology (OT) systems from the general corporate network to prevent the spread of Ransomware.
- Credential Hardening: Enforce Zero Trust principles by requiring multi-factor authentication for all remote access points, particularly for VPNs and RDP sessions.
- Enhanced Monitoring: Integrate endpoint telemetry with a SIEM to identify behavioral anomalies, such as the unauthorized use of administrative tools like PowerShell or PsExec.
The Role of Initial Access Brokers
The rise of Initial Access Brokers (IABs) has significantly lowered the barrier to entry for cybercriminals in the LAC region. These actors specialize in gaining Privilege Escalation and then selling that access to the highest bidder on specialized underground forums. This specialization allows even less-technical actors to participate in high-impact campaigns.
Modern SOC teams must monitor for unauthorized account creations and changes in access patterns that indicate an IAB has successfully breached the perimeter. By identifying these early-stage IoC indicators, organizations can prevent a full-scale Data Breach before the access is handed off to a ransomware affiliate.
