TL;DR: Ransomware and malware can turn Latin American bank incidents into customer-visible disruption, according to GlobalSign. Banking controls need to treat privileged access, recovery accounts and payment integrity as one chain, or outages and abuse can spread together.
Editorial analysis by NHI Mgmt Group, based on content published by GlobalSign: “Las instituciones financieras de América Latina son uno de los principales objetivos de los ciberdelincuentes”.
Key questions
Q: Why do cloud banking environments increase operational and cyber risk?
A: Cloud environments increase risk when teams migrate services faster than they redesign trust boundaries.
Q: What should financial institutions monitor to detect abuse of banking workflows?
A: They should monitor abnormal changes in transaction patterns, exchange-rate manipulation, privileged session activity and unexpected access to payment or online banking systems.
Q: Where do bank security controls usually fail when ransomware reaches online banking systems?
A: They fail when privileged access, recovery accounts and service connections are not isolated from each other.
Practitioner guidance
- Map banking service identities and privileged paths Inventory the accounts, service principals and admin routes that support online banking, payment processing and server management.
- Segment ransomware containment zones Place ATMs, online banking portals, interbank payment systems and core servers into distinct containment zones with limited trust between them.
- Harden high-risk transaction workflows Add stronger authorisation, anomaly checks and reconciliation controls around exchange-rate changes, transfers and other high-value banking actions.
Bottom line: Latin American banks face a compound risk where ransomware, malware and transactional abuse can all turn into customer-visible disruption.

Banking security in LATAM is now a governance problem, not a point-control problem. The article shows repeated pressure across banks, payment systems and online channels, which means security teams are no longer dealing with isolated technical events. They are managing a failure of containment across identity, infrastructure and transaction integrity. Practitioners should treat the banking attack surface as an operating model issue, not a perimeter issue.
A question worth separating out:
Q: What is the difference between banking fraud controls and ransomware containment?
A: Fraud controls focus on preventing unauthorised financial actions, while ransomware containment focuses on stopping attacker movement and limiting service disruption. Banks need both because one incident can create both fraud and outage effects. If these controls are separated too cleanly, teams can miss the overlap between compromised access and transactional abuse.
