![]() ![]() ProtonMail does, however, offer the ability to send end-to-end encrypted emails to non-ProtonMail accounts through our outside encryption feature or through PGP (for advanced users). This is why for sensitive communications, we recommend that your contacts also utilize a ProtonMail account. For example, if you send an email to somebody using Yahoo mail and Yahoo is breached, that message may be exposed through the recipient’s inbox. However, if presented with a valid order from a Swiss court involving a case of criminal activity that is against Swiss law, ProtonMail can be compelled to share account metadata (but not message contents or attachments) with law enforcement.Emails between ProtonMail accounts and non-ProtonMail accounts are also zero-access encrypted on our servers, but they are not end-to-end encrypted in transit, and copies stored on your recipient’s email service may be vulnerable to exposure. Microsoft Threat Modeling Tool 2016 How To Secure YourBecause ProtonMail messages are encrypted before they leave the user’s browser, an attacker cannot get message data by simply listening in on the communications. An MITM attack cannot easily be used on a large scale to perform mass surveillance.As the name suggests, an MITM is where an adversary sits between the user’s device and the server. Man-in-the-Middle (MITM) attacksThis is a far more difficult attack that can typically only be executed by a strong adversary (like a government) and is generally a targeted attack. ProtonMail does not and can not guard against a compromise of a user’s machine.Learn more about common types of user compromise and how to secure your data. Even if you use the world’s most secure electronic communication system, advanced encryption does you no good if your password has been compromised or there is a keylogger on your computer recording all of your keystrokes. This is a form of key-pinning that provides extra protection by detecting if a fake public key is delivered to your device for that contact. This allows users to “trust” the public key of a contact you have verified. Using ProtonMail’s mobile apps and our desktop Bridge software may reduce the risk of MITM attacks as those environments are more difficult to compromise than web.ProtonMail also features another anti-MITM feature called Address Verification. There are browser plugins that can be used to detect forged certificates and greatly reduce the risk of an MITM attack. Generally speaking, a successful MITM attack requires breaking TLS, typically by using a forged TLS certificate. ProtonMail employs TLS to secure the delivery of our software to users’ browsers and prevent tampering of our code en route. ProtonMail has implemented numerous safeguards against this on the server level which make this a difficult attack to pull off successfully in an undetectable way. Such an attacker could conceivably change the ProtonMail software to send bad encryption code to users’ browsers that would somehow allow the attacker to get unencrypted data. Unauthorized backdoorAnother attack vector would be if an attacker somehow gained access to ProtonMail’s servers in Switzerland without us noticing. For highly sensitive communications, we recommend enabling Address Verification.Learn how to use Address Verification. In this case, ProtonMail offers a great deal of protection. For example, you fear a competitor may want to sue you under false pretenses to get access to sensitive data. Below are some examples of recommended and not recommended use cases for ProtonMail: RecommendedYou have sensitive business information that you want to make sure is protected from competitors and other malicious parties. In such a case, we don’t think encryption would be of much benefit, as this XKCD comic would apply. There are, however, some risks for users facing a strong adversary, such as a government focusing all its resources on a very specific target. ![]() ConclusionWe would like to conclude with a few thoughts about privacy and surveillance in general. While we can offer more protection and security, we cannot guarantee your safety against a powerful adversary. A powerful state adversary will also be better positioned to launch one of the attacks described above against you, which may negate the privacy protection provided by ProtonMail. The Internet is generally not anonymous, and if you are breaking Swiss law, a law-abiding company such as ProtonMail can be legally compelled to log your IP address. Not recommendedIf you are attempting to leak state secrets (as was the case of Edward Snowden) or going up against a powerful state adversary, email may not be the most secure medium for communications. Free voice dictation software for macHowever, the vast majority of our users are individuals seeking greater control over their data, or journalists and activists living under authoritarian regimes where freedom of speech and privacy are not respected. Like any technology, ProtonMail can be used for good or bad. A very powerful counterargument to that, which we recommend everybody watch, can be found here.There are also critics who assert that by building ProtonMail, we are providing a tool for criminals to evade the authorities.
