I was watching this DefCon talking about Solid State Drives (SSDs) destroying forensic and data recovery jobs. It was interesting to note, that the speaker did acknowledge that it is unknown how long deleted files will remain recoverable for.
I have read several academic papers which state it is unknown how long a deleted file is recoverable for on an SSD due to wear-leveing, and that secure erasure of individual files was impossible. Some SSDs do have features to shred them, however this would wipe all of the contents and is irrelevant to cryptolocker-ransomware malware.
I was curious how cryptolocker-ransomware being spread in the wild addresses this problem, as it appears simply jumping ship from HDD to SDD would drastically increase the chances of file recovery?
