Microsoft Office 365 email encryption may not be as watertight as it seems

Summary by Ground News

Security researchers at WithSecure found that it is possible to partially or fully infer the contents of encrypted messages sent through Microsoft Office 365. The issue is due to the use of a weak block cipher mode of operation. Microsoft told WithSecure that the issue does not meet the bar for security servicing, nor is it considered a breach, hence there will be no patch for it.
