Notice of Ransomware Infections at York
Please be advised that several infections of a type of
ransomware/malware known as “Odin” have been detected on York
workstations today. Ransomware infects computers like a virus and
then encrypts all files on the local PC and any network shares it
finds, making the information inaccessible, offering a decryption
key for a ransom.
The main method of infection is via email attachments containing
the code that installs the virus, which is then run when the user
clicks on the attachment.
How to protect against ransomware
York has deployed technology and systems to help filter malware
and related cyber-attacks, including removal/renaming of dangerous
attachment types, however protecting against ransomware requires
vigilance from the University community also.
Important ways you can help including the following:
- Do NOT click links or open attachments in unsolicited email
from people or groups you don’t recognize
- Keep your anti-virus software up to date and enabled; York
provides Trend Micro AV to all staff, faculty and students at the
University
- Keep your computer up to date, including key software such as
your web browser, Adobe Reader, Adobe Flash, Microsoft Silverlight
or Java
- Use York network shared drives, or similar that also has
regular backups, to store important information, and ensure such
information is NOT stored only on your local computer
- If you or your department maintain servers, ensure they are
up to date from an operating system AND application layer
perspective
If you suspect your computer is infected or being attacked, shut
down/power off your computer immediately (to stop encryption of
files) and contact your local IT support or the UIT Service Desk.
