Ransomware attacks

Stop ransomware attacks with Mimecast

Preventing ransomware attacks requires new technology.

Ransomware attacks are increasing at an alarming rate. The U.S. government estimates that companies are subject to more than 4,000 attacks each day, resulting in $1 billion in ransom paid each year.

While ransomware attacks come in many variants – Cryptowall, Locky and Cryptolocker are among the most common – they each follow a similar pattern. A user receives an email with an attachment that looks like a Word document, an invoice, a package notice or a fax report, along with a message that convinces the user the attachment is real. When the attachment is opened, the ransomware virus runs a file that encrypts files and documents on the user's computer. The user receives a message stating that they can get the encryption key and regain access to their files only by paying a ransom.

When trying to prevent ransomware attacks, the challenge is keeping pace with the ingenuity of attackers. And because most ransomware attacks are launched through email, any defensive measures must focus on email security. That's why so many companies around the world choose to combat ransomware attacks with help from Mimecast.

Mimecast's defenses against ransomware attacks.

To thwart attacks like Cryptolocker and Locky ransomware, Mimecast provides Targeted Threat Protection services that prevent users from accessing malicious attachments. Mimecast scans all incoming and archived email and, using advanced threat intelligence, identifies attachments deemed to be suspicious. Attachments can either be preemptively sandboxed until they can be examined for ransomware attacks, or immediately transcribed to a safe format that allows users to have instant access to the content in the attachment.

Mimecast also prevents users from clicking on potentially malicious links in email by scanning the destination website in real time and blocking any suspicious URLs.

To reduce the impact of ransomware attacks, Mimecast Enterprise Information Archiving provides safe storage of all email content in the cloud, enabling administrators to roll back data to a point just before ransomware attack. And Mimecast Mailbox Continuity enables users to have continuous access to email during an outage caused by an attack, a natural disaster, hardware failure or human error.
