A Silent Cyber Storm Is Reshaping Latin
For years, Latin America was largely viewed as a region targeted by cybercriminals and state-sponsored hackers operating from elsewhere. That perception is rapidly changing. A newly uncovered cyber campaign known as Operation Escaneo reveals the emergence of threat actors capable of executing highly sophisticated attacks once associated only with elite nation-state groups.
Security researchers at CloudSEK have uncovered evidence that a threat actor known as MexicanMafia, also referred to as PanchoVilla, conducted a widespread and technically advanced cyber espionage and financially motivated operation across critical infrastructure organizations between 2025 and 2026. The campaign demonstrates a remarkable level of operational maturity, custom-built attack tools, advanced persistence mechanisms, and the ability to compromise both Windows and Linux environments.
What makes this operation especially alarming is not merely its technical sophistication. It is the possibility that financial crime and intelligence gathering are being conducted simultaneously, creating a hybrid threat model that blurs the traditional boundaries between cybercriminal gangs and advanced persistent threat groups.
The discovery signals an important shift in the cybersecurity landscape of Latin America and may represent the beginning of a new generation of regional cyber actors capable of challenging organizations far beyond their traditional geographic targets.
The Rise of MexicanMafia and Its Expanding Reach
MexicanMafia has already built a reputation for targeting some of Mexico’s most sensitive institutions and infrastructure providers.
Previous victims reportedly include state governments, law enforcement agencies, judicial institutions, tax authorities, and major energy organizations. Such targeting patterns indicate a threat actor interested in acquiring information that extends beyond simple financial theft.
Operation Escaneo demonstrates that the group has significantly evolved. Instead of conducting isolated attacks, researchers observed a coordinated campaign stretching across multiple countries and sectors.
Mexico remained the primary target, while Ecuador experienced substantial attack activity. Researchers also identified operational traces extending into Portugal, suggesting that the group’s ambitions may no longer be restricted to Latin America alone.
This geographic expansion highlights a growing confidence among regional threat actors who increasingly possess the resources and expertise required for international operations.
A Sophisticated Arsenal Built for Modern Cyber Warfare
One of the most striking discoveries from
At the center of the campaign sits a proprietary reconnaissance framework known as Kimera. This custom-built engine enables attackers to automate target discovery, map network infrastructure, and identify vulnerable systems before launching deeper attacks.
Unlike ordinary cybercriminal operations that rely heavily on publicly available tools, MexicanMafia appears to invest heavily in maintaining its own offensive capabilities.
Researchers identified an impressive exploit arsenal targeting widely deployed enterprise technologies from vendors such as Fortinet, Ivanti, and Cisco.
The attackers also deployed advanced command-and-control infrastructure using:
Neo-reGeorg web shells
Chisel reverse tunnels
Compromised Cisco routers
Persistent GRE tunnels
Custom reconnaissance frameworks
Portable lateral movement toolkits
The result is a highly resilient attack architecture capable of surviving defensive efforts and maintaining long-term access to victim environments.
How Operation Escaneo Infiltrates Organizations
The attack chain begins with large-scale reconnaissance using Kimera.
After identifying vulnerable systems, attackers exploit several well-known vulnerabilities affecting perimeter security devices and enterprise software.
Among the vulnerabilities abused were:
CVE-2022-42475
CVE-2023-27997
CVE-2024-21762
CVE-2023-46805
CVE-2024-21887
CVE-2020-1938 (GhostCat)
These vulnerabilities affect products widely used by governments, corporations, and critical infrastructure operators worldwide.
Once inside a network, attackers establish persistence through web shells and covert tunnels designed to evade detection.
The campaign then progresses toward privilege escalation and lateral movement using both known vulnerabilities and administrative tools.
Researchers observed the use of:
Zerologon
EternalBlue
PwnKit
Remote Desktop Protocol (RDP)
PsExec
Impacket
This combination allows attackers to move rapidly throughout compromised networks while blending in with legitimate administrative activity.
Windows, Linux, SAP, and Oracle Were All in Scope
Many cybercriminal operations focus on a narrow range of targets.
Operation Escaneo was different.
Researchers discovered capabilities allowing attackers to operate across both Windows and Linux environments while also targeting enterprise applications and databases.
The threat actor reportedly compromised:
Active Directory environments
SAP ERP systems
Oracle database platforms
Mobile Device Management infrastructure
Cryptographic repositories
This level of cross-platform capability is typically associated with highly experienced operators who understand enterprise infrastructure at a deep level.
Such versatility significantly increases the potential damage that can be inflicted during a breach.
Financial Crime Meets Intelligence Collection
Perhaps the most intriguing aspect of Operation Escaneo is the apparent overlap between financial motives and intelligence gathering.
Traditionally, cybercriminal groups focus on monetization through ransomware, credential theft, or data sales. State-sponsored actors prioritize espionage and strategic intelligence collection.
MexicanMafia appears to occupy a gray area between these categories.
Researchers found evidence of theft involving highly sensitive assets, including cryptographic materials and SSL private keys belonging to government institutions.
The compromise of mobile device management infrastructure also suggests access to highly valuable intelligence data.
According to CloudSEK researchers, this may not necessarily indicate direct state sponsorship. Instead, the group may simply collect everything of value and monetize whatever can be sold while separately retaining information useful for intelligence purposes.
This creates a unique threat model where financial opportunism and intelligence collection operate simultaneously, potentially without strict coordination.
The approach is highly efficient and difficult for defenders to predict because the attackers do not appear constrained by a single objective.
Why This Matters Beyond Latin America
The implications of Operation Escaneo extend far beyond the countries directly targeted.
Historically, one of the defining characteristics of advanced persistent threats was their superior technical capability.
That distinction is disappearing.
Modern cybercriminal groups increasingly possess:
Custom malware development capabilities
Proprietary reconnaissance tools
Exploit research expertise
Infrastructure compromise techniques
Long-term persistence mechanisms
The gap separating cybercriminals from nation-state operators continues to shrink.
Operation Escaneo demonstrates that sophisticated offensive capabilities are no longer exclusive to intelligence agencies or government-backed groups.
Organizations worldwide should view this campaign as evidence that highly capable attackers can emerge from any region and pursue any objective.
Defenders Must Adapt to the New Reality
CloudSEK’s findings highlight several urgent defensive priorities.
Organizations should immediately patch exposed vulnerabilities affecting perimeter technologies, particularly those impacting Fortinet, Ivanti, and Apache Tomcat deployments.
Network administrators should also audit environments for suspicious tunnels, unauthorized routing changes, and unexpected communications paths.
Visibility remains critical.
Many organizations focus heavily on endpoint detection while overlooking network-level persistence techniques that attackers increasingly exploit.
Effective defense requires:
Strong network segmentation
Continuous vulnerability management
Endpoint monitoring
Application-layer visibility
Strict access controls
Active threat hunting
Continuous logging and forensic readiness
The era of relying solely on traditional perimeter defenses has ended.
Modern attackers are persistent, adaptive, and increasingly capable of maintaining access for extended periods.
What Undercode Say:
Operation Escaneo represents more than another cybercrime campaign.
The most important takeaway is the convergence of criminal and intelligence operations.
Historically, cybersecurity professionals classified actors into separate categories.
Nation-state actors collected intelligence.
Cybercriminals pursued money.
Hacktivists sought publicity.
Operation Escaneo demonstrates that those distinctions are becoming obsolete.
The attackers appear willing to steal anything valuable.
Financial records become targets.
Government secrets become targets.
Cryptographic keys become targets.
Infrastructure access becomes targets.
This collect everything strategy maximizes operational flexibility.
The use of custom tooling is especially significant.
Most criminal groups depend heavily on publicly available frameworks.
MexicanMafia invested in proprietary reconnaissance systems.
That requires resources, expertise, testing environments, and operational planning.
The router-level persistence observed in this campaign deserves particular attention.
Many organizations monitor endpoints aggressively.
Far fewer monitor routers.
Compromised network infrastructure can provide long-term stealth access.
The SAP targeting is another warning sign.
Enterprise resource planning systems contain some of the most valuable organizational data available.
Compromising ERP environments provides attackers access to finance, supply chain, procurement, human resources, and strategic planning information.
The campaign also illustrates the growing importance of credential theft.
Attackers increasingly prefer legitimate access over malware deployment.
Valid credentials generate fewer alerts.
They blend naturally into enterprise traffic.
Operation Escaneo demonstrates advanced understanding of hybrid environments.
Linux systems were targeted.
Windows systems were targeted.
Enterprise databases were targeted.
Network devices were targeted.
This reflects a modern attack philosophy focused on total ecosystem compromise.
Latin America is becoming more than a victim region.
It is becoming an active cyber battlefield.
Threat actors are developing indigenous capabilities.
Custom frameworks indicate local technical expertise.
That trend will likely accelerate.
Organizations that continue to view regional cyber groups as unsophisticated will face increasing risk.
The campaign also reinforces the importance of threat intelligence sharing.
Many indicators identified in Operation Escaneo could help organizations detect intrusions before major damage occurs.
The shrinking capability gap between cybercriminals and APT groups may become one of the defining cybersecurity trends of the next decade.
Security teams must stop asking whether an attacker is a criminal or an intelligence operator.
The better question is whether the attacker possesses advanced capabilities.
Operation Escaneo clearly shows the answer can be yes.
