Ransomware is software that encrypts data on your own computer and on network drives. Payment of a ransom is required for decryption of the data.
In principle, the same precautions apply here as with traditional phishing, only here the objective is not the capture of credentials, but loss of documents and other data. We therefore ask you to pay particular attention to the following points:
- Be sure to periodically back up your important data to external media, and only have these media connected to your computer during the backup.
It is recommended that you use the free backup version of Veeam for Windows or Linux: https://www.veeam.com/endpoint-backup-free.html
Other manufacturers offer similar solutions.
- Request only user rights required for the work on your computer and if necessary reactivate or tighten the so-called User Access Control in Windows.
- Be wary of emails that “smell” like phishing! Recognising phishing is often difficult, but with a little bit of attention you can find hints like fake sender addresses, links to web pages that are not related to the email content, no personal addresses or alleged documents in zipped format that point to malicious intent.
- Found data carriers, such as USB memory sticks, should generally not be used; see
- In case of uncertainty or if you have inadvertently opened a questionable link, always ask your IT representative for advice!
