Information Technology Services (ITS) Security Advisory Notice:

May 14 2017

IT security issue to be aware of:

As you likely heard, the largest ever ransomware attack occurred last Friday with a reported 45,000 attacks occurring distributed over 100 countries. These interrupted some essential services in Russia, India, Brazil, the UK, US and China.  Canada was lucky so far, however our local neighbour was impacted adversely, Lakeridge Health. 

The malware is delivered in a phishing email, and the payload hidden in the attachment. 

If you accidentally become infected, immediately:

    1. Turn off your PC.
    2. Call the IT Service Desk @ 905-721-3333
    3. Do not hesitate.

This ransomware variant copies itself quickly across shared drives.

You will know you are infected if you see this ransom demand screen displayed by WannaCry:
