In Latin America, fintech is often cited as “rewriting the rules.” With a smartphone and a few clicks, people are sending money across borders, investing in crypto, juggling currencies, and buying whatever they need—no bank branch required. For millions, the app is the bank. And that’s both brilliant and risky.

This mobile-first momentum is unlocking access like never before. LATAM fintechs are building powerful platforms that offer instant international transfers, biometric logins, digital dollar wallets, QR-based payments, and even embedded crypto investing. They’re not just catching up; they’re leaping ahead. And these fintechs are doing it for a generation that expects their financial tools to be fast, fluid, and global.

The standouts

A few names worth knowing:

  • Nubank built a mobile-only bank with 90+ million users and made no-fee credit cool.
  • Mercado Pago turned a regional e-commerce wallet into a full-fledged financial ecosystem.
  • EBANX helps global giants like Spotify sell to LATAM locals through familiar payment rails.
  • Clip arms Mexico’s small businesses with card readers and digital commerce.
  • Bitso brings crypto mainstream in Mexico, Brazil, and Argentina.
  • Kueski, Creditas, dLocal, Neon, and Kavak—they’re all part of a wave reshaping how LATAM moves money.

But here’s the thing no one loves to talk about: attackers love this success too.

Cybercriminals are zeroing in

Follow the incentives, and the story becomes clear: fintech apps hold money, credentials, identity data, and transactional behavior—all in one place. And when the information vault is in a smartphone, cybercriminals don’t need to break in through the front door—they just need a weakness in the code, the API, the device, or the network.

Now layer that onto LATAM, and you see why this part of the world is fertile hunting ground. Mobile-first adoption has outpaced traditional security infrastructure in Central and South America for years. Millions of users are coming online fast, often skipping past desktop banking entirely. Many use low-end Android devices that lack the latest security patches. 

Regulatory frameworks vary and can be limited in strength, and smaller fintechs—who are focused on speed and scale—don’t always factor security in from day one. For attackers, this is an optimal scenario: rapid fintech growth, fragmented defenses, millions of users unfamiliar with digital hygiene, and apps full of valuable data.

The risk is real. A single repackaged app, a clever phishing campaign, or a targeted Trojan can yield a massive return. Sophisticated cybercrime groups are treating fintech the way VCs would: as high-potential targets worth investing in.

As LATAM fintechs scale, so does their exposure. Mobile apps, “portals to financial freedom,” have become bullseyes for attackers. Trojans mimic apps to steal credentials. Jailbroken devices give hackers a base to launch attacks from. Repackaged apps float around app stores laced with malware. Man-in-the-middle attacks eavesdrop on data in transit. Overlay attacks trick users into sending their credentials into thieves’ awaiting hands.

Even the superapps are not immune. In 2022, Mercado Libre saw a breach that affected 300,000 users. It wasn’t catastrophic, but it was loud. And it was a signal: nobody’s untouchable.

Security can’t be an afterthought

Fintechs can’t protect only their backends and hope for the best. The front door, aka “the app,” is where users engage and where attackers probe. If that entry point cracks, everything behind it is at risk: money, trust, and reputation.

Top of mind protection techniques

  • App hardening: Build apps that are tamper-resistant by design.
  • Runtime detection: Don’t just hope nothing goes wrong; watch for it as the app loads.
  • MITM defense: Protect every byte of user data in motion.
  • Threat telemetry: Make your app a sensor, not just a target.
  • AI/ML: Spot threat patterns & initiate countermeasures before attacks do harm.

More than simply compliance checkboxes, app security is about differentiation. The fintechs that win long-term will be the ones that earn user trust and keep it. That means treating app defense as infrastructure, not insurance. It’s what lets you scale confidently, partner credibly, and sleep at night.
