A threat actor claims to have leaked more than 100,000 records from a public water management entity, exposing Peruvian national identity document numbers, citizen names, emails, and internal complaint registries.
A database containing more than 100,000 records originating from the Peruvian public infrastructure agency Special Project Chavimochic has been posted on an underground cybercrime forum. The archive, totaling approximately 200 megabytes of structured data, reportedly encompasses sensitive personally identifiable information (PII) of citizens and personnel, including national identification document (DNI) numbers, full names, email addresses, internal documents, and formal public complaint records.
The targeting of regional infrastructure authorities highlights persistent vulnerabilities in public sector digital services, where web-facing administrative portals, public record submission forms, and backend relational databases are frequently exposed to automated scanning and credential reuse attacks.
The threat actor claims to have obtained a full database export containing structured citizen records and internal workflow communications. The compromised dataset includes multiple categories of sensitive identity and administrative records:
National Identity Numbers: More than 100,000 citizen and employee Documento Nacional de Identidad (DNI) entries.
Personal Identifiable Information: Full names, personal and government email addresses, and contact records.
Citizen Complaints and Claims: Formal submissions logged through the entity's public complaint book (Libro de Reclamaciones) and documentation processing workflows (Trámite Documentario).
Internal Documentation: Administrative files, operational correspondence, and structural project records associated with regional hydraulic development operations.
The presence of government-issued identification numbers alongside full names and official correspondence makes this dataset particularly potent for secondary social engineering and unauthorized account recovery attempts.
While the threat actor has not publicly published specific exploit tooling or proprietary initial access scripts, the attack pattern aligns with established threat actor tactics targeting public sector web portals across Latin America. Web applications operating on government subdomains frequently run legacy Content Management Systems (CMS), custom PHP portals, or exposed API interfaces that lack modern input validation.
Adversaries targeting public infrastructure databases typically execute a structured progression:
Reconnaissance (MITRE ATT&CK T1596): Scanning external public endpoints across chavimochic.gob.pe to identify exposed database ports (e.g., MySQL on TCP 3306, PostgreSQL on TCP 5432) or vulnerable web applications.
Initial Access (MITRE ATT&CK T1190 or T1078): Exploiting public-facing web vulnerabilities, such as Structured Query Language Injection (SQLi) or Insecure Direct Object References (IDOR), or authenticating with compromised administrative credentials recovered from information-stealer malware logs.
Data Collection and Exfiltration (MITRE ATT&CK T1005 / T1567): Executing bulk export queries across database tables holding citizen submissions and administrative records, followed by staging and downloading compressed archive files over HTTPS or web services.
Impact (MITRE ATT&CK T1491 / T1485): Publishing the exfiltrated archives on illicit marketplaces to build underground reputation or facilitate subsequent extortion.
Proactive attack surface visibility is essential to catch these exposures before threat actors do. Organizations can evaluate exposed digital assets through continuous Attack Surface Management to detect misconfigured endpoints and open database services.

The emerging PEAR Team has leaked 1.8 TB of highly sensitive corporate and client records from Canada-based Exchange Group. Our detailed technical analysis exposes their data-only extortion tactics, RMM persistence methods, and actionable security telemetry to protect enterprise environments.
The downstream consequences of this breach extend beyond direct infrastructure disruption to serious individual identity exposure and organizational security risks.
Adversaries often weaponize leaked DNI numbers, verified email addresses, and names to design highly convincing spear-phishing campaigns. By referencing legitimate citizen complaint reference numbers or official infrastructure project names, malicious actors can impersonate regional government officials to target contractors, farmers, and municipal partners.
In many administrative systems, a valid DNI number combined with full names and birth records serves as primary authentication or secondary identity verification for banking, municipal services, and telecommunications accounts. Stolen identity sets are frequently repurposed for synthetic identity fraud, unauthorized SIM swaps, or fraudulent social benefit claims.
Exfiltrated internal project files and administrative email trails often contain organizational charts, network naming conventions, server hostnames, and software versions. Threat groups actively analyze leaked public sector documentation to map internal network boundaries for follow-on access attempts.

Public sector organizations handling personal citizen data must navigate stringent data protection and disclosure obligations following a confirmed unauthorized disclosure.
Data Protection Authority Reporting: Under national privacy frameworks (such as Peru's National Authority for Personal Data Protection / ANPDP under Law No. 29733), organizations must document security breaches, investigate the scope of unauthorized access, and implement mandatory remediation measures.
Citizen and Partner Notification: Affected individuals whose DNI numbers, complaints, and contact information were compromised should receive transparent breach notifications warning them of potential impersonation and phishing risks.
Critical Infrastructure Governance: Entities managing vital hydraulic and agricultural resources face heightened supervisory review to ensure core operational operational systems (OT/ICS) remain segregated from public-facing web networks.
Continuous monitoring across subterranean channels is vital for tracking exfiltrated assets. Implementing enterprise Dark Web Monitoring enables security teams to identify exposed company data, credential pairs, and internal documents the moment they surface on underground forums.
Security teams managing public sector or enterprise portals should immediately execute verification, containment, and hardening protocols to protect database integrity and user identities.
Audit Relational Database Logs: Review database query logs for high-volume SELECT * statements, table export commands (such as mysqldump or COPY TO), and anomalous connections originating from untrusted public IP ranges.
Inspect Web Server Access Logs: Analyze Apache, Nginx, or IIS logs for automated vulnerability scanning patterns, SQL injection payloads (e.g., UNION SELECT, SLEEP(), `' OR '1'='1`), and unauthorized calls to document management endpoints.
Review Citizen Complaint Portals: Audit Access Control Lists (ACLs) and API authentication mechanisms protecting citizen submission forms, ensuring unauthenticated users cannot traverse records via predictable ID parameters.
Enforce Phishing-Resistant MFA: Mandate multi-factor authentication across all staff email inboxes, administrative portals, VPN gateways, and remote management interfaces.
Revoke and Rotate Credentials: Force an immediate password reset and session invalidation for all administrative, developer, and operational accounts associated with the domain.
Isolate Database Tiers: Restrict database port listening to internal localhost or private virtual networks, ensuring that database management ports are never directly accessible from the public Internet.
Apply Encryption at Rest: Implement Transparent Data Encryption (TDE) for sensitive database tables storing citizen identity numbers and official claims.
