From Western's ITS:
RISK: VERY HIGH
ALERT: Five Western faculties or business units are reporting new ransom-ware infections. This unnamed threat appears to be either an audio wave file attachment, an infected MP4 (movie file) or an email appearing to provide a user's resume. If you receive a resume unexpectedly (out of the blue) with an attachment, or with attached media files from someone not in your contact list, do not open the attachment.
Ransomware is software which scans a computer encrypting all data files it finds, basically hijacking the data. Unless backups exist, this data is unrecoverable unless payment is made to the virus author.
ITS is reporting our community is at risk. Faculty, Staff & Students are being targeted and victimized by a new ransomeware threat whose name is not yet known. Thankfully no faculty has lost data because all affected data was backed up, showing the importance of having backups.
