The biggest Bulgarian e-mail portal abv.bg launches war against the cooks presenting themselves as members of the company and stealing personal data and passwords of its users by demanding upgrading of data, while the link they provide leads to a fishing page. The frauds demand the providing of a password and user name, the three full names of the user and the civil identification number, and sometimes even a copy of the person’s identity card, the 24Hours daily writes. Abv.bg prepares a special video to explain to the public how to identify the fake messages, the publication further informs.
