Banking vishing in Colombia: Banco de Bogotá alerts to fraudulent calls
Banco de Bogotá warns of fraudulent calls impersonating its Servilínea line to steal passwords and data. Twenty-five per cent of fraud victims in Colombia fell victim to vishing in the first half of 2026.
Criminals impersonate Banco de Bogotá's customer service line to steal data
According to semana.com, Banco de Bogotá issued an alert directed at its customers and users of the Colombian financial system amid a rise in cases of vishing, a form of fraud in which criminals impersonate companies or institutions by telephone to obtain personal information, access passwords or to direct victims to fraudulent links.
The Fraud Trends study by TransUnion for the first half of 2026 revealed that 25 per cent of those who claimed to have lost money were victims of this method, making it one of the most impactful forms of deception in the country.
The technique has become more sophisticated in recent weeks. Fraudsters use telephone numbers that appear on the receiver's screen as identical to those of banking entities, creating a false sense of security for users.
In the specific case of Banco de Bogotá, criminals have directed their attacks against Servilínea, the entity's official customer service channel. Victims receive calls with that line's identification and are manipulated into handing over passwords, personal data, or accessing malicious links.
In response to this situation, the entity urged its customers not to provide confidential information over the telephone, to verify the authenticity of any contact before responding and to communicate directly with official channels if they receive any suspicious calls.
