Digital fraud in Mexico online store protection 2026, Digi Mart USA News (Mexico): How many messages with an “urgent” link did you receive this week? If you sell online, the same flood of lures falls on your customers and your team, and CONDUSEF has measured it.
Of the 22,199 complaints it received between January and March 2026, 37.4% were related to possible fraud, and 94% of those cases involved multiple banking institutions. This guide sets out what fraudsters are doing this year and what an online store can do before it is targeted.
CONDUSEF itself mapped the trend in two statements from May and June. The first describes an increase in fraud attempts through SMS messages, messaging apps and fake links, all relying on emotional manipulation: fear, urgency or uncertainty, triggered by supposed notices from banks, tax refunds, online purchases, fines or digital services.
The second adds social networks, fraudulent websites and identity theft. Between January and May 2026, more than 35,000 complaints for possible fraud were recorded; complaints involving multiple banking institutions rose 18% compared with the same period of 2025, and in sofipos and sofomes the increase was around 49%.
One data point challenges the belief that this only affects older people. The sharpest increases were among people aged 50 to 59 (about 25%), 40 to 49 (22%) and young adults aged 18 to 29 (nearly 20%), the same age groups that buy online and run online stores.
Before activating any filter, map the full path of a payment: what the customer sees when choosing card, bank transfer or cash, how long it takes to clear, and what your dashboard shows at each stage. That map helps you spot an altered screenshot or an “I already paid you” claim with no movement behind it.
Cash payment at convenience stores is the step most often misunderstood, because the buyer generates a reference from a phone and the money is credited afterward. Once you understand that sequence, any receipt that departs from it should raise a flag.
From this comes a rule: never release an order based on an image sent by chat. The only valid confirmation is the one that appears in your own dashboard.
Many small shops in Mexico close sales through messaging and request card number, expiration date and security code right there. That turns the business into an unprotected store of sensitive data, exposed to a stolen phone or a hacked account.
The safe approach is for card data never to pass through you: the customer enters it into the processor’s form, which encrypts and validates it.
If you sell through an e-commerce platform, integration should use an official module that redirects to the processor’s checkout and returns the result to your store. Whatever the platform, the payment button must come from the processor’s official site, not from a file shared by third parties.
Payment processors include anti-fraud layers that many sellers never review. These rules reject or hold transactions with unusual signals, such as several purchases in a row from the same card, an amount that is atypical for your history, or a shipping address that does not match the card’s country.
There is also the additional authentication the issuing bank requests from the cardholder, which shifts part of the chargeback liability.
Each processor configures these tools under different names, so review your own dashboard before assuming you are “already protected.” If you use the processor mentioned above, reading about Mercado Pago’s anti-fraud tools can save an afternoon of clicking, since it explains which options are off by default. Overly strict filters reject legitimate buyers, so track how many good transactions you lose in the first two weeks and adjust.
According to CONDUSEF, the most targeted link in 2026 is the person: in a business, whoever answers messages or logs into the dashboard from a phone. An email posing as the processor asking you to “reactivate the account,” or a call from someone claiming to be from the security department asking for a code, are typical examples.
No team member should log into the dashboard from links received by message; type the address manually or use the official application.
Enable two-step verification on the processor, the business email and the store platform, using a second factor that does not rely only on SMS.
A persistent phone number should be checked before you answer. In June 2026 CONDUSEF launched the “Consulta y Reporta” tool to check and report numbers linked to possible fraud; in its first week it recorded more than 11,000 queries and nearly 5,000 registered numbers.
An unrecognized charge can end in a chargeback, which costs the seller the product, the shipping and sometimes a fee. Documenting every order (proof of delivery, messages with the buyer, matching shipping and payment data) is what allows you to dispute it.
On the customer side, the route to file a claim goes first through their bank and, if there is no response, through CONDUSEF.
If you do only one thing this week, log into your processor’s dashboard, check which anti-fraud filters are off, and at least enable the issuer’s additional authentication and two-step verification on your account. It takes less than an hour and targets the mechanisms CONDUSEF has seen growing in 2026.
