Overview
- Banamex launched a public campaign that tells customers never to open links or install apps sent by SMS, WhatsApp, email or social posts and to contact the bank by verified channels if they suspect compromise.
- Fraudsters use social engineering to imitate official messages and push victims to download fake applications or files that harvest passwords and banking data.
- The bank’s guidance includes downloading apps only from official stores, checking the app developer name before installing, reviewing account and card movements regularly, and calling the institution using numbers found on its website or app.
- Official data show a rise in complaints: Condusef recorded an 18% increase in possible banking fraud claims from January to May 2026, totaling more than 34,300 reports with typical losses reported between 20,000 and 50,000 pesos.
- The fraud wave affects traditional banks, fintechs and Sofipos, prompting continued industry monitoring and consumer alerts that aim to reduce theft, speed detection of unauthorized transactions, and limit financial harm to customers.
