Mimecast also scans attachments and preemptively sandboxes any file that appears to be malicious. If the destination website is deemed to be suspicious based on Mimecast's advanced threat intelligence, the link will be blocked and the user will not be able to load the site.
To enable ransomware prevention, Mimecast scans the URLs in every incoming and archived email, every time a user clicks on a link. Mimecast email security services offer tools to fend off viruses, malware, spam and data leaks, as well as advanced threats like phishing, spear-phishing, impersonation fraud and ransomware. Mimecast provides industry-leading solutions for email security, archiving and continuity, delivered via a cloud-based subscription service that lets you achieve resilience in the face of crypto virus attacks and other advanced threats. To protect against ransomware, you need a multi-layered approach that focuses on preventing attacks as well as mitigating the effect of successful crypto virus attack. The cost of a crypto virus is much higher than the ransom paid to regain access to files – the loss of productivity and potential loss of data also adversely affect the bottom line. Once the crypto virus is launched, it encrypts a large number of files on a user's computer or on servers, hard drives and other storage devices throughout the organization.
Crypto virus attacks are usually initiated when a user clicks a link in an email for a malicious website or opens a malicious attachment that appears to be an invoice, shipping notice, a fax report or a Word document. A crypto virus is a type of ransomware virus like Locky or Cryptowall that encrypts files on a compromised computer and demands a ransom in return for a decryption code.Ĭrypto virus attacks are on the rise, with as many as 4,000 attacks each day and more than $1 billion in ransom paid each year, as estimated by the U.S.
