Security researchers have discovered a new strain of ransomware coded entirely in Java-script, which could increase its chances of being activated.Unlike executable program files, Java-script documents do not always trigger a security warning on Windows or, require administrator access to run.
Named RAA, the malware is disguised as a document and starts encrypting files immediately when opened.
People should avoid opening attachments from unknown sources to stay safe.
The .js (Java-script) file type is automatically blocked in some email packages, particularly Outlook. G-mail doesn't appear to block it.
Don't open unknown attachments, particularly those with a .js extension.
Don't open macro enabled Office docs either (such as .docm and .xlsm files) - and keep your anti-virus right up to date.
Additionally, Windows can be instructed not to start the "Windows Based Script Host" when a .js file is double-clicked.
