Deleted cloud files can be recovered from smartphones

Via InfoWorld.com:

If you think the files you delete from your mobile device and file-sharing service are really gone for good, think again. Researchers from the University of Glasgow have discovered that they could fully recover images, audio files, PDFs, and Word documents deleted from Dropbox, Box, and SugarSync, using both an HTC Android smartphone and an iPhone. 

The revelation, outlined in a report titled "Using Smartphones as a Proxy for Forensic Evidence contained in Cloud Storage," represents an excellent example as to why companies need to approach both BYOD and cloud adoption with care. In and of themselves, neither end-user mobile devices nor mainstream, consumer-focused file-sharing services are equipped with enterprise-level security, yet employees of all stripes are increasingly using both for work as well as pleasure. Together, they can create perfect storm for data insecurity, as these research results demonstrate.
