Ransomware: A Quick Guide to Reduce Risk

What is ransomware?

Ransomware is a class of malicious software that holds your data hostage by blocking access and demanding payment. In some instances, the software may even threaten to leak your data unless you pay.

Did you know?

Even if you do pay (Which you should not!), the bad actor will still keep your data and may continue to request additional payments.

 

What are some ways ransomware infects computers?

Most commonly, ransomware infections come from successful phishing attempts in which the victim downloads or opens a fraudulent attachment. Sometimes, infections can occur when a victim starts a download from a fraudulent website.

 

What do I do if I suspect a ransomware infection on my computer?

Stop what you are doing, shut down your computer, and call the Help Desk at 610-526-7440. If you encounter this issue outside of Help Desk hours, please shut down the affected computer immediately and call the Help Desk when it opens or email help@brynmawr.edu from a different device.

 

How do I prevent a ransomware infection?

Have healthy information security habits!

  1. Be wary of fraudulent emails.
  2. Restrict file downloads to senders and websites you trust. Know it’s safe before you download!
  3. Run a virus scan every two weeks.
  4. Be adept at identifying and avoiding fraudulent emails and websites by completing your Information Security Education program at https://www.brynmawr.edu/lits/projects-partnerships/information-security/information-security-education
Did you know?

Sometimes links on legitimate websites can redirect you to a fraudulent website. This most commonly happens on websites for organizations with low funding and, therefore, a small budget for website security. So, always check your website address before starting a download!

Sharing Files and Folders in OneDrive

All folders and sub-folders in OneDrive inherit the permissions of their parent folder. The share settings of individual items within the folder cannot be edited to differ from the folder. The guide below will help ensure that you are only sharing the materials you intend to share and securely deleting them if they need to be deleted.

Uploading and Sharing in OneDrive

  1. Confirm that the files you intend to share adhere to our Data Handling Policy
  2. Upload your files and determine what you would like to share
    • When sharing multiple files with the same people, it is best to group them in a folder
  3. Determine the type of permission you’d like to grant with your collaborators and then share your files and/or folders

Revoking Permissions and Deleting Shared Files in OneDrive

It is crucial to revoke sharing permissions before deleting a file or folder in OneDrive so that deleted files and folders do not end you in your collaborators’ recycle bins where they would be able to restore the files.

To revoke permissions and/or delete only specific files within a shared folder:

  1. move the file out of the shared folder since all files within that folder will automatically inherit the sharing permissions of the folder.
  2. Revoke sharing permissions
  3. Once the permissions have been revoked, you can delete your file(s) and folder(s)
    • If you have accidentally deleted a file you can restore it from the recycling bin

To revoke permissions and/or delete a whole shared folder:

  1. Revoke sharing permissions
  2. Once the permissions have been revoked, you can delete your folder(s)
    • If you have accidentally deleted a file you can restore it from the recycling bin

Departing Faculty and Staff

When a faculty or staff member leaves Bryn Mawr College, access to a variety of College accounts and services changes. Please be mindful of the account access timelines as described in the documentation when moving data because LITS is unable to perform email or file restores in Office 365.

BIONIC

BIONIC access will end on your final day at the College. If you are a faculty member who is teaching courses the semester of your departure, then your BiONiC access will end 30 days after your date of your departure to allow you to submit grades.

Office 365: Email and OneDrive

You will lose access to your College Office 365 account (which includes email, calendars, OneDrive, and downloaded copies of Microsoft Office) on your final day at the College. If you are a faculty member who is teaching courses in the semester of your departure, you will retain access to your Office 365 account for 30 days after your date of departure.

You may want to set up an automatic reply that provides instructions to people who email you after your departure. Please note: for the first 30 days after you lose access to your account, it will be disabled but not deleted. During this time, senders will not receive an automatic reply unless you set one up. Only after the account is deleted will the sender receive an automated message indicating that the address they are writing to cannot be found.

Please back up any information you may want to keep and transfer ownership of shared OneDrive files to someone in your group if the file is still needed. You can find instructions for backing up your email account and OneDrive here: http://techdocs.blogs.brynmawr.edu/5691

If you have downloaded Microsoft Office from your College Office 365 account to your personal computer, you will be able to keep that copy of Microsoft Office but will need personally renew your subscription of Office 365 to reactivate Microsoft Office.

Moodle

You will lose access to Moodle on your final day at the College. If you are a faculty member who is teaching courses in the semester of your departure, then you will retain access for 30 days after your departure. Once you lose access to Moodle, you will no longer have access any of the files you have stored there. Please download and save any files you feel you may need in the future.

Note: All changes to account access are automatic and based on your departure date. LITS is not able to manually reopen any College accounts.

Network Storage

You will loose access to your personal and departmental network storage (H: and S: drives) on your last day at the College. If you are a departing faculty member teaching courses in the semester of your departure, you will retain access to your network storage for 30 days after your final day. Please back up any information you may need. You can access
these drives from off campus by visiting http://ingress.brynmawr.edu/

Data

Personal data from your College computer and H: drive can be backed up to an external hard drive, a flash drive, or an online data storage service. Please speak with your technician regarding which method is best for you. Before you back up any personal data you wish to keep, discuss with your department to make sure they have any information
they’ll need from the account.

Note: Some data may be subject to legal & ethical restraints and may be a violation to take with you. This data can include student/class data and data related to College processes. If you are unsure what information is permissible to take with you as you depart, please consult with your department and Human Resources and see the Data Handling
Policy at http://www.brynmawr.edu/computing/policies/DataHandlingPolicy.htm

Library Borrowing

All library borrowing privileges end on your final day at the College. If you are also a graduate of Bryn Mawr College, you may request alumni borrowing privileges on the Library web site here: https://brynmawr.wufoo.com/forms/borrowing-privileges/ More information about Bryn Mawr College borrowing policies can be found here: http://www.brynmawr.edu/library/BorrowingPolicies.html

Domain of One’s Own

Domain of One’s Own access will end on your final day at the College. For information on migrating your data, please see http://techdocs.blogs.brynmawr.edu/7430

Voicemail

After your departure, your voicemail is emptied and all settings are reset. The phone extension is then assigned to another employee.

Building Access

OneCard door access ends on your final day at the College. You will still have access to any public buildings on campus, but will not be able to access secured spaces.

See the Server Accounts and Access policy for more information.

Exporting Your Email and OneDrive Files

As students graduate and employees leave the College, access to their College accounts will change. To back up email and OneDrive data from Office 365, follow these instructions:
