API Keys Can Be Phished Too

May 10, 2021

Photo credit: iStock.com/Evkaz We are all very aware of the issues around phishing of user credentials. But it is not only users that can be phished, apps can be too. In previous blogs we’ve shown you how you can make a MITM attack against an app. In this blog we’ll demonstrate that a MITM attack against an app is analogous to a phishing attack against a human. Moreover, there are some similar characteristics to the protections required. Read Full Story

Clubhouse Needs A Bouncer

February 26, 2021

Even if you only have a vague interest in app security I’m sure the recent furore around Clubhouse hasn’t escaped your attention. There is significant buzz around this invite-only iOS app. Enabling live audio chat rooms between participants, it sets the expectation that these interactions are somewhat private and certainly not recorded.  With big celebrity names such as Elon Musk, Kanye West and Oprah Winfrey as users there is a significant demand for a coveted invite.

Scanshake: Meeting the Need for Decentralised Contact Tracing

June 25, 2020

As we discussed in our previous blog, there is a strong argument to be made that Bluetooth Contact tracing is too Blue Sky. The technology has been overhyped, over promised and, in the UK at least , the delivery so bungled that public confidence has been completely undermined. In the meantime we are stepping back to manual contact tracing efforts, with privacy characteristics that don’t come anywhere close to the lofty aspirations of decentralised contact tracing apps.

Is Bluetooth Contact Tracing Too Blue-Sky?

June 24, 2020

Contact tracing has been in the news a lot in recent months. No wonder. It’s widely seen as playing a key role in opening our societies up again after lockdown, and an important part of the strategy for countries that have already done well in suppressing transmissions. As technologists we, and many like us, immediately jumped onto the possibilities of Bluetooth. A ready made technology available on just about every smartphone designed for ubiquitous short range radio communication. Perfect. We just need to throw an app together and we can map all the contacts people are having day to day, so if anyone gets sick we can automatically alert anyone else that might have been exposed. Cool. Should be ready in a couple of weeks, right? Read Full Story

UK Contact Tracing App Privacy Risks

May 5, 2020

More details of the UK's controversial NHSX contact tracing app are being released as the app starts a wider scale trial on the Isle of Wight this week. NHSX is a digital transformation group associated with the UK National Health Service. Why controversial? There are many reasons, some to do with how the app development was initially procured, but also specifically from a technical perspective as the UK has opted for a centralised contact tracing approach rather than the decentralised model being championed by Apple and Google amongst others (including ourselves).
