We would like to warn our customers and readers for the uprising of cyber crime. Over the last 6 months months, 5 customers have been the victim of ransomware like CryptoWall.

The virus penetrates the network mostly by email and is mostly invisible for up-to-date antivirus software.
The infection takes place as soon as you open an attachment. It is not possible to decrypt your encrypted data without paying the "ransom". Some software is available on the internet to decrypt but it doesn't cover all ransomware and might cost a lot of time. A restore from backup is often the only solution.

- The vulnerabilities are used for searching for programmatical holes to break into hardware and software.
