Twitter's New Encrypted DMs: Are They Really Secure?
0Twitter has announced the launch of encrypted direct messages (DMs) for paying subscribers. This new feature allows users to communicate more securely, as their messages will be stored only on their devices and not on Twitter's servers.
To use encrypted DMs, users must be paying subscribers to Twitter Blue, Twitter's premium subscription service. Additionally, both the sender and recipient of the message must be using Twitter Blue in order for the message to be encrypted.
Encrypted DMs will appear as separate conversations from regular DMs in the Twitter app. They will also be limited to one-on-one messages, so group chats will not be possible at this time.
While encrypted DMs offer a higher level of security, they are not completely impervious to attack. For example, a "man-in-the-middle" attack could allow an attacker to intercept and read encrypted messages. Additionally, Twitter could be compelled by law to decrypt messages, even if both the sender and recipient are using Twitter Blue.
Overall, encrypted DMs are a welcome addition to Twitter's suite of features. However, it is important to be aware of the limitations of this feature before using it.
