Discovering that an eCommerce store has sent their credit card data to a malicious third party is the worst nightmare of many shoppers. They adopt an eminently sensible “once bitten, twice shy” attitude towards retailers who allow sensitive financial data to fall into the hands of criminals. Leaking credit card data is a great way […]

Bugs are an inevitable part of the software development process. As hard as developers try to avoid them — and they try very hard indeed — mistakes will be made and some of those mistakes will cause security vulnerabilities. What’s important is how developers handle vulnerabilities when they do occur, including how they communicate about […]

WordPress 4.7 was released towards the end of last year and brought with it a host of new features, including a new default theme, theme starter content, and REST API content endpoints.

Magento eCommerce stores are high value targets for online criminals.

Passwords are not a great authentication method — a point that’s been made many times, not least by me on this blog. Passwords are great in theory, but in practice, when users are asked to choose and manage strong passwords, they don’t. They choose easy-to-remember and hence easy-to-guess passwords. And they use the same password […]

A brute force attack is the least sophisticated technique online criminals have to compromise WordPress sites. It doesn’t take advantage of obscure coding errors or advanced social engineering techniques. Rather, a brute force attacker simply tries lots of username and password combinations until they find one that works. The execution may be more or less […]
