Mobile applications are increasingly used in all areas of business: HR, finance, insurance, transport, and so on. As a result, they are prime targets for attackers.

There are several ways of assessing the security of a mobile application. In this article, we present the “offensive” approach, which we believe to be the most effective: mobile penetration testing (or mobile pentesting). We detail the principles, objectives, methodology and features tested during mobile application penetration testing.

Security misconfiguration is a worrying problem, occupying fifth place in the OWASP Top 10. In fact, we frequently encounter many vulnerabilities of this type during our web application penetration tests. Furthermore, this security issue affects a large number of web applications (90% according to OWASP).

In this article, we present this type of vulnerability through the prism of the OWASP Top 10, using attack scenarios. We also detail the best practices and measures to be implemented to protect against them.

Third-party components are omnipresent in web applications. Libraries, frameworks and other system components are used more and more, because they reduce costs and make development easier.

However, like any system, these third-party components may contain vulnerabilities that can be exploited in attacks on web applications. Furthermore, exploits that are discovered, and often made public, can have a snowball effect, compromising an entire web application, servers, database systems, etc.

Faced with an ever-increasing number of internal attacks, network infrastructure security is a key factor in ensuring the confidentiality and integrity of data, as well as the continuity of an organization’s activities.

There are several ways of assessing the security of an internal network. In this article, we present the “offensive” approach, which we believe to be the most effective: internal penetration testing. We detail the principles and objectives, as well as use cases for black box and grey box penetration testing of an internal network.

Faced with an ever-increasing number of sophisticated attacks, web application security is a major challenge. Indeed, security is now crucial to reassure customers, build loyalty and convert prospects.

There are several ways of assessing the security of a web application. In this article, we present the “offensive” approach, which we believe to be the most effective: web application penetration testing. We detail the principles and objectives, as well as use cases for black box, grey box and white box penetration tests on various targets.
