Designing for security

Got a favourite security tool? No? You’re not alone. Most people don’t have a “favourite” because most people don’t even think about their digital security until they see a news story about the latest data breach, or they receive an email from Facebook saying their account has been hacked. If pressed, many will default to anti-virus software. Not because people love scanning their computers for viruses, but because most people feel anxious about security.

Birth of an icon

The lack of design identity and representation in end-to-end encryption The most exciting part about working for a startup company with a niche service product is that I often have to build my own tools in order to do my work. And tools, either digital or IRL (in real life), have always fascinated me. For an app that functions in a completely end-to-end encrypted (E2EE) environment, the time came at Peerio when we needed to put a (tiny) face on this most important feature.

Ask Floh: What SMS 2FA means and why it’s better than nothing

In today’s episode of Ask Floh, we learn about why two-factor authentication (2FA) with SMS is still better than no 2FA at all. Key takeaways: Authenticator apps and authentication keys were designed for two factor authentication SMS might be a convenient way to do 2FA but it wasn’t designed for 2FA and security It’s not hard to compromise a phone number and gain access to someone’s SMS for 2FA Security is always about cost, 2FA is an extra step an attacker has to overcome 2FA using SMS isn’t ideal but it’s better than not using anything Peerio offers 2FA in the form of two-step verification (2SV).

On secure software updates

Software updates can be inconvenient or annoying for a lot of people. Sometimes the process is problematic or the update itself is a step backwards. Then there are the stories of updates installing malware or breaking things. Developers who care about the people who use their software, should take an interest in making the process safer and less painful. A short history of software updates A long, long, time ago people updated software by going to their local shop, buying a box of diskettes or a disc, and launching a long installation process.

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.

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.

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.

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.
