Testing with CucumberJS: a team endeavour to create code quality

By far the most exciting days at Peerio are Wednesdays. We not only gather to internally test the product update that’s about to ship, but we do it playing trivia. That’s the essence of our testing approach: an accessible activity where everyone participates.The tools allowing us to do so are the Gherkin language and the Cucumber testing framework. A language for collaboration Gherkin enables us developers to communicate with designers, project managers, stakeholders, and users.

Ask Floh: How Secure is G Suite?

In this episode of Ask Floh, we dive into the pros and cons of using G Suite, what to watch out for, and when you may need to use a more secure product. 5 key takeaways are: Google has a world-class security team and handles a lot of different kinds of compliance.

Ask Floh: How to build a good security culture at work

Too many “restrictive” security rules at work messing with your productivity? Having a bad security culture is not only harmful to workflow, it can also be bad for security itself. In this week’s Ask Floh, we take a look at what makes a security culture work well, why building a good workplace security culture is important, and three ways to make your security culture better. A good security culture means that everyone owns security and everyone understands what the security risks are.

Ask Floh: Why you don’t need to change your password every 30 days

Do you really need to change your passwords every month? Nope. This common “password security tip” has been debunked. In fact, frequent password changes can actually make things worse. In this week’s Ask Floh, we learn why you should stop changing your passwords and make stronger ones instead. We at Peerio believe in strong passwords. Our Peerio app uses computer generated passwords (account keys) because we need users to have strong passwords to generate strong cryptographic keys, and to ensure users are protected from any attempts to guess their account keys.

Transcript: Alright, hello. Welcome to Ask Floh. I’m here to answer all of your security questions and help you survive in the digital world. So today, there’s a question from Ajay in Toronto. And he asks:

Embedded server-side spy chips not a risk for Peerio users’ data

Yesterday, a Bloomberg Businessweek article exposed a possible supply chain compromise on many cloud platforms. Attackers embedded hidden spy chips into server hardware during the manufacturing process, which allowed them complete control of the server and access to data passing through and stored on those servers. The provider of our server infrastructure denies that any of their servers were compromised in way mentioned in the Bloomberg’s article, but even if they were compromised, this should not worry Peerio users.

Ask Floh: How to protect against Business Email Compromise

How WhatsApp's Latest Security Bug Could Gaslight You

The latest WhatsApp vulnerability could let hackers impersonate you and gaslight your chat group buddies. Should you be worried? In the video below, our CTO Floh explains how the flaw works and why using end-to-end encryption is still a good thing. Transcript: Right. So WhatsApp has a gaslighting problem. Or rather, they have a vulnerability. That means that messages can be tweaked in a way that makes them seem like they’re possibly something other than what the sender intended them to be.

Filesystem Upgrade (or Unearthing the Hidden Excitement of Strong Foundations)

Within the next thirty years, there’s a 99% chance that California is hit by an earthquake so strong, it’s classified as “major”. How can 40 million Californians possibly deal with such a forecast? One possibility is to design earthquake-proof buildings. The strongest aspect of any structure designed to withstand a natural disaster of that magnitude lies it’s foundation. A properly engineered base transmits the charges of each seismic wave to the nearby land; this allows the building’s structure to adapt to the shaking earth, ensuring safety and stability even through tremors.

How to Build a Billion Dollar Password in 2018

We use passwords to defend our banking information, medical records, and personal communications, but how much do you really know about this little string of characters you trust to protect your data? Most people’s familiarity is limited to what they are told when signing up for a new service, something like “must be at least 8-characters long”, “include a number”, and “mix upper and lowercase characters”. And why would you want to know more?

Why Passphrases are worse for being better

Following the publication of How To Build A Billion Dollar Password, I spent an embarrassing amount of time diving deeper down the password rabbit hole. I conducted very deep research, ended up presenting at a conference dedicated to passwords, and then motioned to remove passphrases from Peerio entirely. Here’s how that happened and why passphrases are still pretty useful. Our passphrases worked. Originally we allowed users to select their own passwords.

Be Curious

Designing Secure Group Chat in Peerio

Last week, researchers from the Ruhr University Bochum released a paper revealing weaknesses in WhatsApp’s security design. Specifically, they discovered that WhatsApp’s servers have complete control over the user list in a group chat, meaning a malicious server could add members to the group. This effectively defeats the goals of end-to-end encryption, as anyone who’s able to access the servers — attackers, WhatsApp staff, or authorities able to legally prompt action from WhatsApp — could discreetly add whoever they want to an existing group.

Encryption Basics

"When you send something to your friend Rabbit, your message doesn't actually go directly to him." Lots of companies say that they encrypt data, but it’s important to know just what type of encryption they use. Unless companies specify that they use end-to-end encryption, they’re most likely only encrypting data in-transit and at-rest. Here’s how messaging apps generally work. When you send something to your friend Rabbit, your message doesn’t actually go directly to him.
