Be vigilant about ransomware
At the moment, there is a lot of news about ransomware targeting companies and institutions. Ransomware is type of virus that encrypts files, and demands a ransom for decrypting them again.
In order to prevent the distribution of ransomware, the ISSC makes sure the workstations and servers of our university are continuously up to date. This weekend will also be used to deploy the latest Microsoft security patches.
You yourself can also take action to prevent damage by ransomware. If you receive an email from an unknown sender, do not open any attachment that comes with it. In case of doubt about the validity of an email, file or link, please contact the ISSC Helpdesk during business hours, we are glad to advise in these matters.
If you do get affected by ransomware on your university workplace, please shut down your workstation immediately and contact us as soon as possible, so we may take the appropriate measures. Under no circumstances take up the offer to pay the ransom, as this does not automatically mean your files will be restored. Paying the ransom will also incentivize the perpetrators to try this again. The ISSC can restore the files you saved on the network from backup.
Do take care of proper security at home too. Always run the latest updates that Microsoft provides, if you are running the Windows operating system. Make use of antivirus software, and make regular backups of your files, for example on an external hard drive.</p>
