I don't think there is anything specific you should need to worry about, as long as you keep backups longer than it will take you to notice. I suspect the notice period should be short (usually they will recursively change a LOT of files, and also create a txt file in every folder telling you how to pay the ransom. You could use some post backup script to query the number of changed files and alert against some configured value, but this would be very much site specific. Remember, they don't change all files, so if only 10% of your files are of the type that will be encrypted, then this could be prone to false alarms. IMHO, they generally target MS Office document formats, as well as other well known database files/etc. Regards, Adam -- Adam Goryachev Website Managers www.websitemanagers.com.au ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
