Safeguard against a ransom virus with Mimecast
A ransom virus, or ransomware virus, is an attack that takes control of files and data on a computer and permits users to regain access only after paying a fee or ransom. In the past few years, ransom virus incidents have risen sharply – the U.S. government estimates that more than 4,000 ransom virus attacks occur every day and that companies and individuals collectively are paying more than $1 billion in ransom each year.
There are many variations of the ransom virus but they follow a similar pattern: a user receives an email with an attachment that appears to be an invoice, a Word document, a fax report or another legitimate file. When the user opens the attachment or clicks on a link, the ransom virus is launched, initiating a file that encrypts certain data on the user's computer.
Successful ransomware prevention involves solutions that block malicious attachments and access to URLs. But because ransom virus attacks are constantly evolving, organizations must also take action to prevent ransomware from disrupting business when an attack is successful. Mimecast can help on both accounts.
Mimecast provides email security and archiving services that both prevent ransom virus attacks and minimize the impact on the organization when an attack makes it past security defenses. Offered as a cloud-based, subscription service, Mimecast dramatically simplifies the task of defending against a ransom virus as well as other advanced threats like phishing, spear-phishing and impersonation fraud.
To block ransomware attacks, Mimecast scans all incoming email as well as archived email to detect ransomware code in attachments and URLs. Mimecast rewrites all links in emails, scanning destination websites in real time when clicked to block access to malicious URLs. Suspicious attachments may either be preemptively sandboxed or safely transcribed to a format that allows users instant access to the content within the attachment. Mimecast also provides dynamic user awareness tools that help to protect from ransomware by empowering users to recognize attacks more easily.
Because it is nearly impossible to mitigate every attack, every hour of the day, Mimecast promotes cyber resilience in the face of multiple evolving threats by providing continuous access to email data during and after a ransom virus attack. When an outage occurs – due to a ransom virus attack, a disaster, hardware failure or human error – Mimecast enables users to continue working with email and attachments without any disruption to their workflow. And Mimecast speeds recovery after an attack by providing a cloud archive with redundant and continuous data protection for email, files and IM conversations.
