Thank you for reading the weekly security newsletter. The purpose of this document is to provide our readers with a quick summary of each week's most relevant Linux security headlines. Feature Extras:

- Social engineering is the practice of learning and obtaining valuable information by exploiting human vulnerabilities. It is an art of deception that is considered to be vital for a penetration tester when there is a lack of information about the target that can be exploited.

- When you’re dealing with a security incident it’s essential you – and the rest of your team – not only have the skills they need to comprehensively deal with an issue, but also have a framework to support them as they approach it. This framework means they can focus purely on what they need to do, following a process that removes any vulnerabilities and threats in a proper way – so everyone who depends upon the software you protect can be confident that it’s secure and functioning properly.

In August 2017, I reported a vulnerability to Panera Bread that allowed the full name, home address, email address, food/dietary preferences, username, phone number, birthday and last four digits of a saved credit card to be accessed in bulk for any user that had ever signed up for an account. This includes my own personal data! Despite an explicit acknowledgement of the issue and a promise to fix it, Panera Bread sat on the vulnerability and, as far as I can tell, did nothing about it for eight months. When Brian Krebs publicly broke the news, other news outlets emphasized the usual "We take your security very seriously, security is a top priority for us" prepared statement from Panera Bread. Worse still, the vulnerability was not fixed at all -- which means the company either misrepresented its actual security posture to the media to save face or was not competent enough to determine this fact for themselves. This post establishes a canonical timeline so subsequent reporting doesn't get confused.
