The dangers to IT security are manifold. Not only malware (ransomware, encryption software, Trojans), but also phishing emails, spam, security gaps in hardware and software in addition to direct attacks by hackers threaten the security of technical networks, devices and data.
Complaint mails arrive more frequently or own mails are returned.
Internet and/or mail access only work slowly or not at all: If limits are exceeded when connecting or sending mails, automatic blocks take effect.
The computer reacts "strangely" or slowly (network load constantly high, even if you are not working intensively on the computer).
The URMZ reacts when it becomes known and blocks the university account and mail access. As soon as the URMZ can be sure that your account is no longer compromised and no longer poses a threat to others, your access will be reactivated after your password has been reset. Computers with malware must be re-installed to ensure that no further unwanted malware is hidden.
What does data privacy have to do with it?
Compromising a mailbox or IT device that contains personal data is already a violation of the protection of that data. In addition to IT security, be sure to inform data protection. They will assess the risk together with you and whether further measures, such as reporting to the supervisory authority, may be necessary. Information on reporting channels and deadlines as well as the form for reporting can be found at the Data Protection Officers' websites.
What should I do if I suspect something?
Immediately disconnect the device from the university network (pull the network cable or switch off WLAN)! This will prevent viruses from being passed on to other devices in the same network.
If it's a device from the university:
Immediatly report to the service desk with the following information: Who is reporting, which IT system is affected, what did you observe or how did you work, when did the event occur, where is the affected IT system (building, room, workstation)?
