Security Digest
Microsoft: Insecure Encryption might be leaking data
Microsoft Office 365 offers a method of sending encrypted messages. It uses a security framework named Office 365 Message Encryption (OME) to let users send and receive encrypted emails between users within and outside the organization while withholding all information about the communications themselves.
Microsoft Office 365 Message Encryption (OME) utilizes Electronic Codebook (ECB) for cryptographically encrypting the communication.
In a recent report published by Withsecure, a Finnish cybersecurity firm. The firm reported that this framework is generally insecure and can leak information about the structure of the messages sent. This report comes after U.S. National Institute of Standards and Technology earlier pointed out “ECB mode encrypts plaintext blocks independently, without randomization; therefore, the inspection of any two ciphertext blocks reveals whether or not the corresponding plaintext blocks are equal.”
That being said, the vulnerability does not arise from decryption from a single message but rather from analyzing a store of a large amount of stolen encrypted messages. “An attacker with a large database of messages may infer their content (or parts of it) by analyzing relative locations of repeated sections of the intercepted messages,” the company said.
This is a known threat model known as ’ Hack now, decrypt later’ where attackers can use old leached-out encrypted messages in order to fuel their attacks in the future.
While the thread can be contained by switching to Quantum-resistant algorithms, Withsecure states “Microsoft has no plans to fix this vulnerability the only mitigation is to avoid using Microsoft Office 365 Message Encryption”
Users can protect themselves by editing their old mail flow rules to the rule action that use apply the previous version of OME to use Microsoft Purview Message Encryption, as recommended by Redmond notes in its documentation.
