Best practices to prevent ransomware attacks Perform regular backups of all critical information to limit the impact of data or system loss and to help expedite the recovery process. Ideally, this data should be kept on a separate device, and backups should be stored offline. Establish a Sender Policy Framework SPF,Domain Message Authentication Reporting and Conformance DMARC, and Domain. Keys Identified Mail DKIM for your domain, which is an email validation system designed to prevent spam by detecting email spoofing by which most of the ransomware samples successfully reaches the corporate email boxes. Dont open attachments in unsolicited e mails, even if they come from people in your contact list, and never click on a URL contained in an unsolicited e mail, even if the link seems benign. In cases of genuine URLs close out the e mail and go to the organizations website directly through browser. Restrict execution of powershell WSCRIPT in enterprise environment Ensure installation and use of the latest version currently v. Power. Shell, with enhanced logging enabled. Send the associated logs to a centralized log repository for monitoring and analysis. Application whitelistingStrict implementation of Software Restriction Policies SRP to block binaries running from APPDATA, PROGRAMDATA and TEMP paths. Ransomware sample drops and executes generally from these locations. Enforce application whitelisting on all endpoint workstations. Deploy web and email filters on the network. Configure these devices to scan for known bad domains, sources, and addresses block these before receiving and downloading messages. Scan all emails, attachments, and downloads both on the host and at the mail gateway with a reputable antivirus solution. Disable macros in Microsoft Office products. Some Office products allow for the disabling of macros that originate from outside of an organization and can provide a hybrid approach when the organization depends on the legitimate use of macros. For Windows, specific settings can block macros originating from the Internet from running. Configure access controls including file, directory, and network share permissions with least privilege in mind. If a user only needs to read specific files, they should not have write access to those files, directories, or shares. Maintain updated Antivirus software on all systems. Consider installing Enhanced Mitigation Experience Toolkit, or similar host level anti exploitation tools. Block the attachments of file types, exepiftmpurlvbvbescrregcerpstcmdcombatdlldathlphtajswsf. Regularly check the contents of backup files of databases for any unauthorized encrypted contents of data records or external elements, backdoors malicious scripts. Keep the operating system third party applications MS office, browsers, browser Plugins up to date with the latest patches. Follow safe practices when browsing the web. Ensure the web browsers are secured enough with appropriate content controls. Network segmentation and segregation into security zones help protect sensitive information and critical services. Separate administrative network from business processes with physical controls and Virtual Local Area Networks. Disable remote Desktop Connections, employ least privileged accounts. Ensure integrity of the codes scripts being used in database, authentication and sensitive systems, Check regularly for the integrity of the information stored in the databases. Restrict users abilities permissions to install and run unwanted software applications. Enable personal firewalls on workstations. Implement strict External Device USB drive usage policy. Employ data at rest and data in transit encryption. Carry out vulnerability Assessment and Penetration Testing VAPT and information security audit of critical networkssystems, especially database servers from CERT IN empaneled auditors. Repeat audits at regular intervals. Individuals or organizations are not encouraged to pay the ransom, as this does not guarantee files will be released. Report such instances of fraud to CERT In and Law Enforcement agencies. Generic Prevention Tools Removal Tools Download Free Bot Removal Tool. Crystal. Maker 2 for Windows Release Notes.
