How to encrypt email (Gmail, Outlook iOS, OSX, Android, Webmail)

Security News - 14 min 16 sek zpět
Email was one of the earliest forms of communication on the internet, and if you’re reading this you almost undoubtedly have at least one email address. Critics today decry the eventual fall of email, but for now it’s still one of the most universal means of communicating with other people that we have. One of the biggest problems with this cornerstone of electronic communication is that it isn’t very private. By default, most email providers do not provide the means to encrypt messages or attachments. This leaves email users susceptible to hackers, snoops, and thieves.

So you want to start encrypting your email? Well, let’s start by saying that setting up email encryption yourself is not the most convenient process. You don’t need a degree in cryptography or anything, but it will take a dash of tech savvy. We’ll walk you through the process later on in this article.

Alternatively, you can use an off-the-shelf encrypted email client. Tutanota is one such secure email service, with apps for mobile and a web mail client. It even encrypts your attachments and contact lists. Tutanota is open-source, so it can be audited by third parties to ensure it’s safe. All encryption takes place in the background. While we can vouch for Tutanota, it’s worth mentioning that there are a lot of email apps out there that claim to offer end-to-end encryption, but many contain security vulnerabilities and other shortcomings. Do your research before choosing an off-the-shelf secure email app.

If you’d prefer to configure your own email encryption, keep reading.

Google: Security Keys Neutralized Employee Phishing

Security News - 14 min 16 sek zpět
Google has not had any of its 85,000+ employees successfully phished on their work-related accounts since early 2017, when it began requiring all employees to use physical Security Keys in place of passwords and one-time codes, the company told KrebsOnSecurity.

Security Keys are inexpensive USB-based devices that offer an alternative approach to two-factor authentication (2FA), which requires the user to log in to a Web site using something they know (the password) and something they have (e.g., a mobile device).

Crypto gripes, election security, and mandatory cybersec school: Uncle Sam´s cyber task force emits todo list for govt

Security News - 14 min 16 sek zpět
The US Department of Justice (DOJ) this week released the first report from its Cyber Digital Task Force – which was set up in February to advise the government on strengthening its online defenses.
The report [PDF], compiled by 34 people from six different government agencies, examines the challenges facing Uncle Sam´s agencies in enforcing the law and protecting the public from hackers. It also lays out what the government needs to do to thwart looming threats to its computer networks.

Let´s (not) Encrypt

If you´ve been following the news for the last few years it will come as no surprise that the Justice Department is not a fan of the common man having access to encryption.
The report bemoans the current state of encryption and its ability to keep the government from gathering and analyzing traffic for criminal investigations. The word ´encryption´ comes up 17 times in the report, not once in a favorable light.
In the past several years, the Department has seen the proliferation of default encryption where the only person who can access the unencrypted information is the end user, the report reads.
The advent of such widespread and increasingly sophisticated encryption technologies that prevent lawful access poses a significant impediment to the investigation of most types of criminal activity.

Quantum computing revenue to hit $15 billion in 2028 due to AI, R&D, cybersecurity

Security News - 14 min 16 sek zpět
The demand for quantum computing services will be driven by some process hungry research and development projects as well as by the emergence of several applications including advanced artificial intelligence algorithms, next-generation encryption, traffic routing and scheduling, protein synthesis, and/or the design of advanced chemicals and materials. These applications require a new processing paradigm that classical computers, bound by Moore’s law, cannot cope with. However, one should not expect quantum computers to displace their classical counterparts anytime soon.

The FBI now says encryption is good for you

Computerworld.com [Hacking News] - 1 min 22 sek zpět

Apple has faced an unequal battle in recent years as some lawmakers, the FBI, and regulators insist that the company create backdoors through which to access messages and other parts of its platform.

Apple and others have always insisted that there is no such thing as a safe backdoor, and that if one person has access, then it’s only a matter of time until others gain access, too. 

Use encryption for all your communications

Now, the FBI seems to agree.

In a recent security warning, the FBI and the US Infrastructure Security Agency have warned people to use encrypted apps such as iMessage and FaceTime for communication in order to retain security resilience against foreign hackers

They also warn people to avoid using Rich Communication Services (RCS) when sharing messages between iPhones and Android devices, as RCS does not yet provide end-to-end encryption. (It is allegedly coming eventually, according to RCS standards body, the GSMA). What this means is that Android and iPhone users should probably consider installing Signal for cross platform communications, which does provide cross-platform encryption. 

Apple also continues to invest in encryption technologies to protect its customers, and recently introduced upgraded protection against future high-level attacks that use quantum computers to break into your communications.  

An about face?

What’s noteworthy about the FBI warning is that the agency has been battling Apple for years to convince it to put backdoors into its encryption — ostensibly to enable law enforcement. Apple has resisted so far, arguing that once you leave any form of vulnerability in any platform you are automatically placing customers at risk. 

Knowledge of these back doors will inevitably slip outside the control of law enforcement into the hands of nation state attackers and — eventually — criminal groups, making everybody far less secure and placing personal, commercial, and national interest at risk. Not only does such weakened encryption directly threaten personal privacy, it also undermines national security. 

A former head of UK national security agency MI5 warned of this almost a decade ago, while Apple software Vice President Craig Federighi has similarly warned: “Weakening security makes no sense when you consider that customers rely on our products to keep their personal information safe, run their businesses or even manage vital infrastructure like power grids and transportation systems.”

All the same, demands that Apple weaken platform security by diluting device encryption have remained. But with the attack environment now in a red zone, the FBI issued its warning about encryption.

It comes after a CISA warning concerning ongoing attacks by China-based hackers.

So, what is the FBI saying? 

“Our suggestion, what we have told folks internally, is not new here: Encryption is your friend, whether it’s on text messaging or if you have the capacity to use encrypted voice communication,” said Jeff Greene, executive assistant director for cybersecurity at the CISA. “Even if the adversary is able to intercept the data, if it is encrypted, it will make it impossible [to use].” 

The FBI also shared a recipe for security that should be on the desk of every IT purchaser. It recommends you use mobile devices that automatically receive timely OS updates, have encryption built in, and use multi-factor authentication for most collaboration tools. In other words, use a higher-end smartphone in preference to a low-end land-fill wannabe. Or, given that the best way to ensure security in your tech is to invest in secure products, use an iPhone, which has built-in encryption and is designed with a security-first agenda.

That focus on security likely reflects how Apple approaches the topic. 

The next big war

After all, it was almost a decade ago that Apple CEO Tim Cook warned: “I think some of the top people predict that the next big war is fought on cybersecurity. With hacking getting more and more sophisticated, the hacking community has gone from the hobbyist in the basement to huge, sophisticated companies that are essentially doing this, or groups of people or foreign agents inside and outside the United States. People are running huge enterprises off of hacking and stealing data.

“So yes, every software release we do, we get more and more secure,” he said at the time.

Now, at last, the FBI seems to agree that encryption makes us safer. We really should keep using it, and reject arguments against doing so.
