Some of you will remember the Target and Home Depot cyberattacks in 2013 & 2014, which resulted in $202 million (Sruthi Ramakrishnan, 2017) and $134.5 million USD (Roberts, 2017) of damages respectively. In this blog article, let’s examine these and other infamous hacks in detail to glean important lessons about system and application security.
More and more security companies are including “white-box cryptography” in their product offerings. This is more than buzzword compliance; it’s a recognition that white-box attacks are real, and that the implementation of a cryptographic algorithm is as important as the algorithm itself.
For the average consumer, hopping online to shop is as commonplace as physically going to the mall. No one thinks for a moment about how relatively unsafe it is to conduct business on the web. But in spite of our years’ long dependence on the web for commerce, it’s still astonishingly easy for cybercriminals to hack web-based transactions.
The reason? Web browsers. The fundamental insecurity of web browsers is arguably the weakest link in cyber security today.
We live in a very different world today than we did 10-20 years ago. We’ve never been more connected. So, it’s surprising that software security practices remain in the realm of “We’ve always done it this way before”. Can they really expect to solve today’s security problems with an old way of thinking?
Traditional thinking typically starts with the premise that honest parties control the computer devices and any cryptographic operations are performed free from interference from would-be attackers. Given this, it’s probably understandable
Cryptography is no longer limited to the military and spies. This ancient art underpins modern life. It’s about encoding intelligible data, e.g. numbers, text and transforming them into something unreadable to anyone other than who the information is meant for. The question is, does it need an upgrade for today’s always connected world?
How secure is your house?
Hundreds of times a day we use cryptography in our everyday life. From the lock on the website that you’re browsing, remotely unlocking your car with the key fob to using all kinds of devices.
On a recent flight, I was sat next to a security auditor. He asked “can someone steal keys used to encrypt credit cards from the server memory?” It depends, was my reply. But his question left me wondering. Why hasn’t anyone built a server side white box implementation?
Why does it depend?
Like any implementation, some are more secure than others. If the server side code was using ‘standard cryptographic APIs’ and they were black box implementations then
In Star Wars: The Force Awakens, the sinister First Order dominates the galaxy, with only a small band of trusted resistance fighters left. What’s the link to today’s software world you may ask? It all comes down to the power of cryptography to defeat the dark side.
In this software controlled world the need for software protection is unavoidable. This protection extends to all aspects of day-to-day life. It could be securing your credit card details when shopping on line or a business safeguarding a remote network connection to even protecting premium content such as a blockbuster movie.
