The latest threats, confidence killers and bad behaviors—and a cyber resilience strategy to fix them
CryptoLocker prevention with Mimecast
A CryptoLocker attack involves one of many strains of the crypto virus, a form of ransomware that encrypts files on a compromised computer and demands that the user pay a ransom in order to regain access to their data. The virus typically presents itself as a malicious email attachment that resembles an invoice, shipping notice, a fax report or an Office document. When the user opens the attachment or clicks on a link in the email, the virus initiates a file that encrypts a large number of documents on the computer's hard drive or on network servers and other storage devices.
As the threat of ransomware viruses and the volume of attacks increases, it's no longer enough to focus just on stopping attacks and CryptoLocker prevention – ransomware threats are evolving so rapidly that it may be impossible to prevent an attack 100% of time. In this heightened threat environment, organizations need to also plan for fast recovery should a virus get past their CryptoLocker prevention measures.
Mimecast is an all-in-one subscription service that offers cloud-based solutions for email security, archiving and continuity. With Mimecast, you can protect and manage business email more easily while reducing cost, complexity and risk.
As an SaaS-based solution, Mimecast can be implemented quickly and easily throughout an organization. Mimecast's centralized administrative tools help to simplify the tasks of managing email and configuring services for CryptoLocker prevention. In addition to helping to protect from ransomware, Mimecast provides defenses against phishing, spear-phishing and impersonation fraud as well as other forms of malware, viruses, spam and data leaks.
For CryptoLocker prevention, Mimecast delivers a suite of Targeted Threat Protection services that block access to suspicious URLs and malicious attachments in email. Mimecast scans all email – both incoming and archived messages – and uses advanced threat intelligence to identify potentially dangerous URLs and attachments. If a link is deemed suspicious, Mimecast's prevents a user from loading the destination website. And if an attachment is considered potentially dangerous, Mimecast can either sandbox it until it has been cleared for use or transcribe the contents to a safe format for immediate access by users. Mimecast also provides tools and services for CryptoLocker prevention that train users to become more aware of the techniques used in ransomware attacks.
Because it may be impossible to prevent ransomware 100% of the time, Mimecast provides archiving and continuity services that ensure users have access to their email and files during and after an attack. Mimecast's cloud archive stores multiple copies of each email and file, enabling users to access them during an attack and administrators to restore them quickly during recovery.
