Trojan “Retefe” attacks mails

In their latest Twitter message, the federal government’s Computer Emergency Response Team (CERT) warns of emails infected with malware that are currently circulating. The cybercriminals are taking advantage of the current media coverage about rising health insurance premiums to send fake emails in the name of health insurance companies. The aim of this action is to infect computers with the “Retefe” e-banking Trojan.

The attachment of the manipulated email contains a Word file. By opening this file, the e-banking Trojan “Retefe” is installed, which is targeting personal e-banking login data.

The best way to protect yourself is to keep your operating system up-to-date and install new updates immediately. In the Swiss Business Cloud, we take care of this for you.

We recommend that you study the Swiss government’s rules of conduct carefully.

1. Block the automatic download of images and files in your e-mail program or web browser.

2. Distrust e-mails whose sender address you do not know. Do not open attached documents, programs or links.

3. Be suspicious if someone contacts you with unusual requests and check the caller critically. In the case of unusual contacts and solicitations, it is advisable to consult within the company to verify the accuracy of the request.
