Learn how to prevent ransomware attacks with Mimecast's robust email security and ransomware prevention solutions.
As ransomware attacks continue to plague companies worldwide, organizations are looking for the most effective ways to prevent ransomware from disrupting business.
Ransomware like Cryptolocker or Locky are usually initiated through email. The message usually contains a malicious URL that launches the ransomware virus when clicked, or an attachment that contains malicious macros to execute the virus when opened by an unsuspecting user.
Once the virus has infected a machine or system, it prevents access to or encrypts files and data. Individuals or organizations must pay a ransom in order to get access to their data again. Getting your data back isn't always easy. Ransomware attacks can be devastating for business of all sizes as the average downtime for a ransomware attack is 16 days.
To prevent ransomware, you need a sophisticated security solution that provides multiple tools to detect and block ransomware before it can cause damage. And to truly protect your organization from ransomware, you also need the ability to backup and recover data quickly in the event of a ransomware attack. Mimecast can help on both fronts.

What is ransomware?
Ransomware is a form of cybercrime where attackers install malicious software on a computer to prevent users from accessing their files and systems, holding the data hostage until a ransom is paid. Ransomware is usually spread through phishing attacks that convince unsuspecting users to share login information, to open a malicious attachment, or to visit a website where ransomware software is surreptitiously downloaded to their computer.
How does ransomware prevent users from accessing files?
Ransomware prevents victims from accessing their data by installing software on a user’s computer that encrypts files with strong encryption algorithms that can only be unlocked with a decryption key delivered after ransom is paid. Ransomware may also threaten to leak or expose sensitive or embarrassing files on the user’s computer unless a ransom is paid. Other forms of ransomware use a lock screen technique that encrypts the master boot record of a drive and prevents the computer from being booted up in a live OS environment.
Why should I prevent ransomware?
Failing to prevent ransomware can cause significant damages to an organization. Businesses may experience significant losses in productivity and operations as well as access to critical information. Business may be disrupted for days or weeks as IT teams struggle to recover data. And the loss of revenue and reputation can be devastating to the profitability of an organization.
How to prevent ransomware attacks?
To prevent ransomware attacks, it’s important to adopt a comprehensive approach to security.
What to do if I can’t prevent ransomware?
It’s likely impossible to prevent ransomware 100% of the time, so having a plan in place to respond to a successful attack is critical to protecting data and users. The first item on your task list should be disconnecting all infected computers from the network to prevent ransomware from spreading to other servers or shared storage. You will also want to report the attack to authorities to help prevent ransomware from infecting other businesses. You can report attacks to the U.S. Cybersecurity and Infrastructure Security Agency (CISA) at www.us-cert.gov/report, and to the FBI at a local field office. An effective data backup plan can help to recover files quickly if you’re unable to prevent ransomware attacks. And technology that enables continuous access to email during and after attacks can help to ensure business continuity.
