Criminals have been very busy making fraudulent telephone calls in Switzerland over the past few weeks. Often, such telephone calls seem deceptively real. You can however protect yourself against them.<\/p>\n

As far back as January, EBAS already published information on telephone phishing<\/a>:<\/u> Fraudsters ring victims pretending that they work for banks, authorities or renowned companies and try to obtain sensitive details such as e-banking credentials or credit card data, or to trigger fraudulent remittances.<\/p>\n

Such attacks are usually carried out in a very professional manner and have been on the increase over the past few weeks. Perpetrators frequently use psychological pressure or urgency strategies to entrap their victims into quick reactions and override all common sense.<\/p>\n
