Action to mitigate further ransomware attacks - your computer may restart

Preventative actions will be performed to prevent further ransomware attacks: your computer may restart

A few days ago, ICTS informed campus that a global ransomware attack has impacted many Windows computers. Most computers on campus are protected, but some users have either refused the updates or their computers have not been restarted following the updates. To protect the university network, we must forcibly update and restart these computers, totalling approximately 1000.

How this will affect you

Your Windows computer may be forcibly restarted to apply critical patches to the operating system.

This will occur at 2pm today, 17 May.

To avoid an unexpected restart, please restart your computer as soon as you can if you have not done so since the last Windows patches were applied. Unsecured computers found to be causing serious problems will be disconnected form the UCT network until the issues have been remediated.

ICTS will be releasing patches and updates for the unsupported Windows XP machines via Windows Software Update Service (WSUS).

What is Ransomware?

Ransomware locks files on your computer and demands a ransom in digital currency to restore the files. There is no guarantee that the files will be restored after paying the ransom. Creating a digital currency account and obtaining digital currency is also not a simple process. While attempts to circumvent the spreading and effect of the ransomware (or any other virus) are announced from time to time, these attempts are often nullified because the creators modify the original version.

At least five new versions on the first attack are spreading, and so far about 200 000 infections in 150 countries have been recorded.

Make sure you back up your data regularly, preferably on an external hard drive that is not constantly connected to your computer and stored in a different location.  This is the only guaranteed way to protect your data.

Please report any cyber security incidents to the CSIRT at csirt@uct.ac.za

Massive global ransomware attack underway

A global ransomware attack, which started on Friday has sent shockwaves around the world and has so far impacted over 100 countries, including South Africa.

The ransomware worm, called "WannaCry" infected about 75,000 computer systems on Friday and is continuing to cause issues across the globe.

The ransomware locks up files on your machine and makes them unavailable to you unless you pay the ransom amount. If your system is infected, a pop-up window will appear with instructions on how to pay a ransom of $300.

What do I do?

  1. The ransomware can infect your machine in several ways, including email. Please do not open any suspicious or unfamiliar emails.
  2. If your machine has been compromised, do not pay the ransom. There is no guarantee you will get your data back.
  3. Make sure your anti-virus software is up to date, on your computer as well as other devices such as phones and tablets.
  4. Make sure the latest security patches have been installed and that your computer has been restarted after the updates.
  5. Make sure you back up your data regularly and that your backups are up to date.

 

Please report any cyber security incidents to the CSIRT at csirt@uct.ac.za
