Common ways malware spreads include email attachments, links in emails, downloads of software from rogue sources, drive-by downloads when browsing the web, and lateral movement (i.e., spreading from an infected system to other systems on the network by exploiting vulnerabilities or using compromised credentials). Therefore, you can minimize the risk of infection by being extra vigilant about these issues. Specifically, this means:

  • Click on links in emails only if you are sure that the message came from a legitimate sender and it is clear where the link leads.
  • Open email attachments only if you are sure that the message came from a legitimate sender and you were expecting the attachment.
  • If in doubt, always ask the sender by another means (by phone or in person) what type of link or attachment it is.
  • If you administer your system yourself: Always keep the operating system and all installed programs up to date.
  • When installing new programs, make sure that they come from a trusted source
