Install CIS Keyboard to Block Ransomware

Most ransomware checks the system language and will not install if a CIS language keyboard is detected.

Installing a Russian or Ukrainian keyboard on a Windows PC can serve as a simple defense against many Eastern European malware strains.

Ransomware groups like DarkSide exclude CIS countries to minimize local law enforcement scrutiny.

Widespread use of this trick forces attackers to risk legal protection or lose income if they remove the language check.

This approach is not foolproof and should be complemented by a defense-in-depth cybersecurity strategy.
