TL;DR: Cyberattacks in Latin America rose 38% last year, and incidents affecting Mercado Libre, Samsung, Nvidia, and PressReader show how account compromise, data extortion, and system takeover can spread quickly across large enterprises, according to GlobalSign. The pattern reinforces that identity controls, not just perimeter security, determine how far attackers can move once access is obtained.
Editorial analysis by NHI Mgmt Group, based on content published by GlobalSign: “Noticias de ciberseguridad en América Latina en marzo y abril”.
Key questions
Q: What breaks when a valid account is abused for attack activity?
A: When a trusted account is abused, perimeter controls no longer provide much protection because the attacker is operating inside normal authentication paths.
A: Compromised service credentials are dangerous because they often carry broad privileges, persistent access, and weak human oversight.
Q: What are the signs that identity controls are failing during an active attack?
A: Look for unusual login patterns, new consent grants, rapid token reuse, helpdesk-style vishing followed by legitimate session creation, and access to systems that do not match the user's normal workflow.
Practitioner guidance
- Tighten access scope for high-risk accounts Review which user, employee and administrative accounts can reach sensitive systems, then remove standing access that is not needed for day-to-day work.
- Increase monitoring on identity-driven activity Correlate logins, privilege changes and unusual data access so that a valid session that behaves like an attacker stands out quickly.
- Separate privileged actions from standard user access Require stronger controls for system takeover paths such as admin functions, reset workflows and security changes, especially where one account can affect many systems.
Bottom line: Latin American attack patterns in the article show that account compromise can be enough to turn normal authentication into a route to data exposure, system control or extortion.

Identity is the control plane for regional attack blast radius: The article’s cases show that once attackers gain account access, the boundary that matters is not the perimeter but the scope of trust attached to each identity. That includes human credentials, employee accounts and any shared operational access that can be reused across systems. Practitioners should read this as a governance problem about how far a compromised identity can move.
A question worth separating out:
Q: How should teams respond when a user account is tied to takeover risk?
A: Teams should treat the account as a containment priority, not just a help desk issue. That means revoking access, terminating active sessions, checking for privilege escalation, and reviewing whether the same credentials or role design could let the attacker repeat the path elsewhere.
