A new form of Ransomware has recently spread to 74 countries, and spreading more. This ransomware arrives via phishing emails, and gets onto systems by the user clicking on a link or attachment in a phishing email.
The ransomware works by exploiting a vulnerability in the Windows operating system. Microsoft have released a security patch for this flaw – and CTEKS clients have already had this patch proactively installed. However, we still recommend the following…
- If it looks suspicious – it probably is. Do not click on any links or attachments that come from someone unexpected in your emails.
- Call the email’s sender to confirm the message’s validity. Don’t respond to a suspicious email with an email.
- Be wary of visiting unsafe or unreliable sites.
- Never click on a link that you do not trust on a web page or access to Facebook or messaging applications such as WhatsApp and other applications.
- If you receive a message from your friend with a link, ask him or her before opening the link to confirm, (infected machines send random messages with links).
- Be aware of fraudulent e-mail messages that use names similar to popular services such as PayPal instead of PayPal or use popular service names without commas or excessive characters.
